The z/OS Basic Skills Information Center is a Web-based information resource
intended to help users learn the basic concepts of z/OS, the operating system that
runs most of the IBM mainframe computers in use today. The Information Center
is designed to introduce a new generation of I/T professionals to basic concepts
and help them prepare for a career as a z/OS professional, such as a z/OS systems
programmer.
Specifically, the z/OS Basic Skills Information Center is intended to:
v Provide basic education and information about z/OS without charge
v Shorten the time it takes for people to become productive on the mainframe
v Make it easier for new people to learn z/OS.
To access the z/OS Basic Skills Information Center, open your Web browser to the
following Web site, which is available to all users (no login required):

How to Read Syntax Diagrams
There is one basic rule for reading the syntax diagrams: Follow only one line at a
time from the beginning to the end and code everything you encounter on that
line.
The following rules apply to the conventions that are used in the syntax diagrams
for all the OAM commands:
v Read the syntax diagrams from left to right and from top to bottom.
v Each syntax diagram begins with a double arrowhead () and ends with
opposing arrows ().
v An arrow (─) at the end of a line indicates that the syntax continues on the next
line. A continuation line begins with an arrow (─).
v Commands and keywords are shown in uppercase letters.
v Some commands and keywords have alternative abbreviations; these appear as
part of the stack for that command or keyword. For example, the alternative
abbreviation for DISPLAY is D.
DISPLAY
D
v Where you can choose from two or more keywords, the choices are stacked one
above the other. If one choice within the stack lies on the main path, a keyword
is required, and you must choose one. In the following example you must
choose either DETAIL or STATUS.
DETAIL
STATUS
v If a stack is placed below the main path, a keyword is optional, and you can
choose one or none. In the following example, PURGE, KEEP, and LOCATION
are optional keywords. You can choose any one of the three.
About This Book
xiii
PURGE
KEEP
LOCATION
v Where you can choose from two or more keywords and one of the keywords
appears above the main path, that keyword is the default. You may choose one
or the other of the keywords, but if none is entered, the default keyword is
automatically selected. In the following example you may choose either DETAIL
or STATUS. If neither is chosen, STATUS is automatically selected.
STATUS
DETAIL
v Words or names in italicized, lowercase letters represent information that you
supply. The values of these variables may change depending on the items to
which they refer. For example, volser refers to the serial number of a volume,
while storgrp_name refers to the name of a storage group.
v You must provide all items enclosed in parentheses ( ). You must include the
parentheses. In the following example, you must supply the volume serial
number (volser) and it must be enclosed in parentheses.
DISPLAY
D
SMS,
VOLUME
VOL
(volser)
You would code this as follows:
D SMS,VOL(volser)
The variable volser is the serial number of the volume you wish to display.
v The repeat symbol shown below indicates that you can specify keywords and
variables more than once. The repeat symbol appears above the keywords and
variables that can be repeated. For example, when a comma appears in the
repeat symbol, you must separate repeated keywords or variables with a
comma.
In the following example, you may specify the library_name and one or more
system identification numbers (system_id) that are separated by commas. You
must enclose the name of the library and all of the system IDs in parentheses.
(library_name
)
,
, system_id
You would code this as follows:
(library_name, system_id, system_id, system_id)
The variable library_name is the name of the library you are working with, and
system_id names three different instances of system identification numbers.

z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Chapter 1. Introduction to Tape Library Management
The Object Access Method (OAM) is a component of DFSMSdfp, the base of the
storage management system (SMS) of DFSMS. OAM uses the concepts of
system-managed storage, introduced by SMS, to manage, maintain, and verify tape
volumes and tape libraries within a tape storage environment.
The management of data on tape volumes is not discussed in this manual. See
z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Object
Support for information on OAM's role in the storage of objects on tape volumes.
Also, see z/OS DFSMSrmm Managing and Using Removable Media for information on
of DFSMSrmm's role in the management of data on tape volumes.
In general, a tape library is a set of tape volumes and the set of tape drives where
those volumes may be mounted. The relationship between tape drives and tape
volumes is exclusive; a tape volume residing in a library (library-resident tape
volume) can only be mounted on a tape drive contained in that library
(library-resident tape drive), and a library-resident tape drive can only be used to
mount a tape volume which resides in the same library. A tape library can consist
of one or more tape systems.
When a volume is entered into a tape library, it is assigned to a tape storage group.
A tape library can contain volumes from multiple storage groups, and a storage
group can reside in up to eight libraries.
As new tape data sets are created, the installation allocates data sets to tape
volumes in an SMS-managed tape library by associating one or more tape storage
group names (using the SMS storage group ACS routine) with the allocation
request. DFSMS ensures that only tape devices within the tape libraries associated
with the tape storage groups are allocated to the request. Existing tape data sets on
library-resident volumes are allocated to tape drives within the library where the
volume resides.
Automated Tape Storage
Tape automation provides satisfactory solutions for many of the problems that
occur when tape library storage requires human intervention. Mount times are
reduced from minutes to seconds. The number of lost, misfiled, or damaged tapes
decreases. Security is enhanced because the tape library hardware and tape
cartridges can be kept in a secure area. Customers experience the benefits of a
cost-effective, efficient, and automated method for storing their tape media, and
they drastically reduce the amount of human intervention required to maintain
their tape storage environments.
The IBM Automated Tape Libraries and their supporting software streamline and
automate the roles of the storage administrator, tape operator, and the tape
librarian. They also use the concepts of SMS to manage the tape volumes within
the library.

a discussion of the TotalStorage Automated Tape Library (3584), see “System
Storage Automated Tape Library (3584) System Attachment” on page 14.
Automated Tape Library
An automated tape library dataserver (ATLDS) consists of tape drives, tape
cartridges, a tape cartridge storage area, input and output stations for inserting
and removing cartridges, and a mechanism for moving tape cartridges among
these areas. The volumes within an automated tape library are known as
library-resident tape volumes. Tape volumes can also be located on shelves outside
the automated tape library. These volumes are known as shelf-resident tape
volumes. See Figure 1 on page 10 and Figure 2 on page 12 for examples of the IBM
TotalStorage Enterprise Automated Tape Library (3495) and the IBM TotalStorage
Enterprise Automated Tape Library (3494).
Tape cartridges are stored and retrieved by an automated cartridge accessor. The
cartridges are placed in an input station by the tape library operator. The cartridge
accessor then scans the external volume label on the cartridge, carries the cartridge
to the appropriate storage location, and places it into the library. When a volume
mount is requested, the cartridge accessor retrieves the cartridge from the storage
location, carries it to the requested drive, and mounts the cartridge in the drive.
Upon completion of the tape operation, the tape cartridge is unloaded, the accessor
retrieves it from the drive, and returns it to a storage location in the library.
However, the tape library operator can continue library operation during periods
when the cartridge accessor is not operational. During this time the operator
responds to commands displayed on the manual mode console. This is known as
manual mode operation.
In an ATLDS environment, mount and demount messages are only issued to the
system log and will not appear on the console.
Manual Tape Storage
Manual tape library management provides the advantages of system-managed tape
in a non-automated environment. The tape library operator continues to use the
MVS console to receive tape-related instructions. The library volumes can reside on
a shelf near the tape library drives to satisfy mount requests. The grouping of
volumes and drives provides system-managed support for manual tape libraries in
multiple locations.
Manual Tape Library
A manual tape library (MTL) is an installation-defined set of tape drives and a
customer-defined set of tape volumes with mount capability on those tape drives.
The volumes can be physically stored in shelf storage located near the MTL, but
since these volumes are specifically defined as residing in the MTL, they are
known as library-resident volumes. When the volumes are logically ejected from
the MTL, they become shelf-resident volumes.
In an MTL environment, the operator or tape librarian responds to commands at
the MVS console, manually loading and unloading the tape cartridges. Before a
tape cartridge can be used, the tape cartridge must first be logically entered into an
MTL. Cartridges can be entered into an MTL through invocation of the CBRXLCS
manual cartridge entry (MCE), general use programming interface, or through
invocation of the LIBRARY ENTER command (see “Entering a Tape Volume into
an MTL” on page 106 for more information).

z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Guidelines:
1. Operation of this support outside of the true stand-alone environment is not
intended. To determine feasibility of this support within a non-IBM robotic tape
library, contact the manufacturer of the robotic tape library.
2. If a vendor’s tape device, emulating a 3490E or IBM TotalStorage Enterprise
Tape System 3590 native device, is defined to the library, the manual tape
library support will treat this device as a real 3490E or as a real 3590 Model B.
When entered into the library, the media must be defined as its emulated
media. It is then the user’s responsibility to manage media or device
incompatibilities. This can be managed by keeping incompatible devices with
the same emulated or real device type in separate libraries.
Object Access Method Support for Tape Libraries
OAM uses system-managed storage concepts within the SMS component of
DFSMS to provide the management facilities for the physical movement and
tracking of the tape volumes used within tape libraries.
There are three components of OAM:
v Object Storage and Retrieval (OSR)
v OAM Storage Management Component (OSMC)
v Library Control System (LCS)
This manual covers the use of the LCS component of OAM in support of tape
libraries. For information on the roles of OSR, OSMC, and LCS in support of object
data, see z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide
for Object Support.
OAM provides the following services in support of tape libraries:
v Cartridge entry, eject, audit, mount, and demount processing
v Operator command processing
v Tape configuration database (TCDB) management
v A set of tape library related services which may be used by the installation (see
Chapter 6, “Library Control System (LCS) External Services,” on page 147)
v Installation exits that influence tape processing at four critical points:
– Entering a cartridge into a tape library, or importing logical volumes into a
virtual tape system (VTS)—CBRUXENT
– Ejecting a cartridge from a tape library, or exporting logical volumes from a
VTS—CBRUXEJC
– Changing the use attribute of a tape cartridge—CBRUXCUA
– Allowing the installation to enter a nonlibrary-resident cartridge into a tape
library during allocation processing—CBRUXVNL
See Chapter 7, “Installation Exits,” on page 211 for more information on these
installation exits.
v Unsolicited attention message processing.
Recommendation: Only a subset of the functions above actually execute within the
OAM address space (entry, eject, audit, and unsolicited attention message
processing). Cartridge mount and demount activity (job processing) does not
require the OAM address space. However, since job processing often results in
volumes being entered and error and status messages being displayed, run the
installation with the OAM address space active whenever possible.
Chapter 1. Introduction to Tape Library Management

ISMF Role with Tape Libraries
The storage administrator performs library-related functions through the use of the
Interactive Storage Management Facility (ISMF) library management panels.
ISMF serves two roles in tape library management. First, it allows the storage
administrator to define tape libraries in the tape configuration database (TCDB).
Second, it allows the storage administrator to define tape libraries in specified
source control data sets (SCDSs), making them a part of the SMS configuration
when that SCDS is activated. Upon activation of an SCDS that has tape libraries
defined, an operator on any console within an SMS complex can issue commands
targeted for any tape library within the SMS configuration. Each change associated
with an SCDS does not take effect until that SCDS is activated. Changes to the
TCDB take effect the next time an SCDS that includes that tape library is activated.
Rule: Tape drives associated with either an automated tape library dataserver or a
manual tape library must be defined using the hardware configuration definition
(HCD). For more information on HCD requirements, see “Creating the Hardware
Configuration” on page 80 and to z/OS HCD User's Guide.
ISMF allows the storage administrator to define, alter, list, and display:
v Tape library definitions
v Tape storage group definitions
v Data class definitions
v Storage class definitions
v Management class definitions
Managing the tape library’s volume inventory is also handled through ISMF. For
more detailed information, see Appendix B, “Using ISMF Panels to Define and
Monitor Your Configuration,” on page 327 and z/OS DFSMS Using the Interactive
Storage Management Facility.
Installation Storage Management Policy Overview
Each installation defines a storage management policy that allows effective tape
storage management without requiring user intervention. Through ISMF, the
storage administrator and system programmer define an installation storage
management policy in an SMS configuration.
An SMS configuration for tape libraries consists of the following elements:
v Base configuration. The base configuration identifies the systems and system
groups in an SMS complex and contains installation defaults.
v SMS constructs. Constructs are lists of attributes that are assigned to data sets
and storage areas. An SMS configuration can contain five construct types. The
following describes all five constructs; however, SMS-managed tape uses only
storage group, storage class, and data class. With outboard policy management
support in the Virtual Tape Server (VTS), the storage group, storage class,
management class, and data class names are sent to the library.
– Storage group allows you to define a storage hierarchy and manage that
hierarchy as if it were one large, single storage area.
– Storage class allows you to define different levels of performance objectives
and availability requirements for system-managed storage.
– Data class allows you to define specific data attributes.
– Management class allows you to define different backup, retention, and class
transition characteristics.
4
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
– Aggregate group allows you to group a collection of data objects that form a
data type. This allows the data to be referred to collectively or individually.
An SMS configuration can contain multiple constructs of each type.
System Groups in an SMS Configuration
The systems that share the SMS configuration may be defined in one of two ways:
v As an individual system (the name of the system is known to SMS)
v As part of a system group (only the name of the group is known to SMS). There
can be a maximum of 32 systems, system-group names, or both sharing the SMS
configuration.
Recommendation: Although a system group may be defined to SMS, define all
systems connected to a tape library as individual systems. If the tape library is
connected to a system group, the installation loses the ability to vary the library
online or offline to the individual systems that comprise the group. A VARY
SMS,LIBRARY command directed to a system group causes the library to be varied
online or offline to all the individual systems in the group. There is no way to
direct a VARY SMS,LIBRARY command to an individual system that is part of the
system group.
Storage Groups and Automated Class Selections Routines
A tape storage group is a collection of tape cartridges that are located within one
or more tape libraries. Only a tape storage group may be used in association with
tape libraries. As part of the definition of a tape storage group, one to eight library
names can be associated with the tape storage group. Tape storage groups can
have on each system or system group in the SMS complex any one of the
following four attributes:
ENABLED
The system can create and access data sets on any tape volume
belonging to this storage group. This condition can be changed by
the VARY SMS,STORGRP operator command.
NOTCON
The system cannot create or access data sets on any tape volume
belonging to this storage group. This condition cannot be changed
by the VARY SMS,STORGRP operator command.
DISNEW
The system cannot create a new data set which is the first data set
on a tape volume. It can read an existing data set, extend an
existing data set, and create a new data set that is not the first on a
tape volume. This condition can be changed by the VARY
SMS,STORGRP operator command.
DISALL
The system cannot create or access data sets on any tape volume
belonging to this storage group. This condition can be changed by
the VARY SMS,STORGRP operator command.
Tape storage groups can be associated with one or more tape libraries, but all
volumes of a multivolume data set must be contained within a single library and a
single storage group. If one of the volumes required in a multivolume data set
request resides outside of the library, the volume not in library installation exit
(CBRUXVNL) can be used to direct the volume back into the library.
When a private volume is entered into a tape library and a storage group name is
not provided, OAM sets the storage group name to blanks. The blank storage
Chapter 1. Introduction to Tape Library Management
5
group name becomes the system default. The blank storage group is always
enabled on all systems within the Storage Management Subsystem (SMS) complex.
It is a good idea for the storage administrator to assign all volumes in the blank
storage group to other named storage groups as soon as possible. This allows an
installation to take advantage of the storage group states (ENABLED, NOTCON,
DISNEW, and DISALL). Also, the storage group name can be used to direct a
volume to a particular library or libraries, rather than to any library within the
SMS complex. This ensures that a volume is reentered into the appropriate library
following the ejection of that volume, and provides a filter for reducing the length
of the volume list displayed through ISMF.
Automated class selection (ACS) routines are storage-administrator-defined
routines that automatically identify the storage class, storage group, and data class
that are used for allocation of volumes for new tape data sets. The storage group
definitions in the active control data set (ACDS) contain the names of the libraries
to which these volumes may be assigned. During allocation, these library names
are used to find the associated named collection of tape devices or device pool. The
device pool names are then used during allocation to find the associated device
numbers for the tape drives that may be used to satisfy the request.
Notes:
1. For limitations on the number of device pools refer to “Tape Subsystem (Device
Pool) Limitation” on page 88.
2. When both DASD and tape storage groups are eligible for a new allocation
through the ACS routine, SMS defaults to DASD over the tape storage group,
choosing the more efficient device. The user cannot influence this decision after
the ACS routine has made the storage group selection.
Understanding the Pre-ACS Routine Exit
The pre-ACS routine exit (IGDACSXT) enables an external source, such as a tape
management system, to provide input (through read-only variables) to the ACS
routine to influence construct selection and assignment. The tape management
system can use these variables to direct new allocations to a particular tape library
to coordinate vaulting runs for backups or off-site storage. For more detailed
information regarding this pre-ACS routine exit, see z/OS DFSMS Installation Exits.
Integrated Catalog Facility and the Tape Configuration Database
The integrated catalog facility (ICF) provides support for the following tape
configuration databases:
Volume catalog
A volume catalog (VOLCAT) is an ICF user catalog marked as a volume
catalog. It contains only volume and library entries. There are two types of
VOLCAT: general and specific. The TCDB may be shared by all or some of
the systems and system groups in one or more SMSplexes that have
connection to the tape library dataservers that are defined in the TCDB.
The TCDB is the collection of all VOLCATs—the general and all the
specifics.
The general VOLCAT
The default volume catalog contains all the library records as well as any
volume records that are not recorded in a specific VOLCAT. Each system
must have access to one and only one general VOLCAT. The general
6
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
VOLCAT must be defined before defining a tape library. The name of the
general volume catalog is hlq.VOLCAT.VGENERAL.
A specific VOLCAT
A volume catalog that contains a specific group of volume records based
on the first character of the volume serial number. The name of the specific
volume catalog is hlq.VOLCAT.Vx. For examples on defining VOLCATS,
see “Creating the Tape Configuration Database” on page 78 or z/OS
DFSMS Access Method Services for Catalogs.
Note: The “hlq” and the “x” in the name of the volume catalog, hlq.VOLCAT.Vx,
stand for high-level qualifier and reference to valid character values (A–Z
and 0–9) respectively. For information on changing high-level qualifiers on
VOLCATs, see z/OS DFSMS Managing Catalogs.
The following TCDB records are used in association with tape libraries:
Library record
There is one library record for each tape library. The library record resides
within the general VOLCAT. Each record contains information related to
the library (for example, library name, library ID, and device type) and is
created by the ISMF tape library define option.
Volume record
Each volume record represents a tape volume. It can reside in the general
or the specific VOLCAT. It contains information related to a volume (for
example, volume serial number, library name, and storage group name)
and is created during cartridge entry processing.
Access method services provide users access to catalog entries for tape libraries
and tape volumes, allowing them to create, alter, list and delete entries residing in
the TCDB. However, access method services is used mainly as a recovery tool to
repair damaged catalogs and should be used with caution whenever you create,
alter, and delete TCDB entries. Incorrect use of this recovery tool can cause
database (host, library manager, and tape management) conflicts. For example,
IDCAMS ALTER can be used to change the use attribute of a volume in the TCDB,
but it does not change the library manager’s inventory record or the tape
management system’s database. When changing a volume’s use attribute, use
CBRXLCS FUNC=CUA or ISMF volume ALTER to keep the databases
synchronized. For more information concerning recovery of catalog entries, see
“Establishing Recovery Procedures” on page 94.
MVS Hardware Configuration Definition
MVS hardware configuration definition uses the LIBRARY parameter to define
drives configured to a tape library. For more information on using HCD to define
drives, see “Creating the Hardware Configuration” on page 80 and z/OS HCD
User's Guide.
Rule: Tape drives associated with an automated tape library dataserver, a manual
tape library, or configured as a stand-alone device must be defined using the
hardware configuration definition (HCD).
Chapter 1. Introduction to Tape Library Management

Types of Tape Volumes
Unlike DASD or optical volumes, which are shared among many users, tapes are
assigned to individuals or functions. They are retained for specified periods of time
as required by the storage administration plan for your business. Tape cartridges
that are assigned to a specific individual or function are considered private.
Unassigned tapes are known as scratch and are used in response to a system
scratch request, or assigned as a private tape in response to a nonspecific request
from a user. The volume use attribute (whether the cartridge is private or scratch)
is initially assigned by the cartridge entry installation exit (CBRUXENT) or set by
the ISMF entry default use attribute.
Private Tape Management
You can use private volumes by explicitly requesting a specific volume serial
number.
Scratch Tape Management
All scratch tapes within a library are contained within common scratch pools—one
for each type of media in the library—and cannot be explicitly mounted by
specifying a volume serial number. See page 332 for more information on scratch
threshold processing. Once a tape is removed from a common scratch pool, it is
assigned to a storage group, the volume use attribute is changed to private, and it
remains private until it is returned to scratch status.
Private tapes are returned to the common scratch pool through an ISMF ALTER
request, through the use of the Library Control System (LCS) external services
change use attribute function, or by a tape management system.
Scratch Tape Management in an MTL
In an MTL environment, because there is no outboard category assignment and
outboard selection of a particular scratch volume, the operator, as in the
stand-alone environment, is free to mount an appropriate scratch volume.
Additionally, in an MTL environment, the scratch volume mounted must be of the
appropriate media type for the request, and it must have previously been entered
into the library as a scratch volume in the MTL in which the allocated drive
resides. The ability of the operator to mount a scratch volume enables volume
pooling to work in a fashion similar to that of the stand-alone environment. See
your tape management system for specific implementation details about volume
pooling and the MTL.
If an MTL resident scratch volume is mounted outside of the MTL environment on
a stand-alone device, the volume will remain scratch in the tape configuration
database.
Rule: Keep MTL-resident scratch volumes separate from the stand-alone scratch
pool.
VTS Stacked Tape Management
OAM does not keep volume records in the tape configuration database (TCDB) for
the physical stacked volumes used in the VTS. However, when logical volumes are
exported from a VTS, the stacked volumes containing the logical volumes are
reported through messages and passed to the cartridge eject installation exit
(CBRUXEJC). This is done so that a tape management system can track the
physical stacked volume on which an exported logical volume resides.
8
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
VTS Outboard Policy Management
Outboard policy management enables you to better manage your VTS stacked and
logical volumes. With this support, the SMS construct names that are associated
with a volume (storage class, storage group, management class, and data class) are
sent to the library. When file sequence 1 is written (DISP = NEW), the 8-character
SMS construct names (as assigned through your ACS routines) are passed to the
library. At the library, you can define outboard policy actions for each construct
name, enabling you and the VTS to better manage your volumes. For example,
through the storage group policy and physical volume pooling, you now have the
ability to group logical volumes with common characteristics on a set of physical
stacked volumes.
Duplicate Volume Management
Special care must be taken to mount a volume with a duplicate volume serial
number outside of an IBM managed tape library. When the duplicate volume serial
number is requested, if a volume record exists for that volume in the tape
configuration database indicating that the volume is library resident, the allocation
for that request will be directed to the library in which the volume resides. To
direct the allocation of the duplicate volume to a stand-alone device, a special
reserved storage class name, DUPT@SMS, can be specified with the storage class
parameter on the JCL with DISP=OLD. This will force allocation of this request to
a stand-alone device.
A tape management system such as DFSMSrmm can provide support for
managing duplicate volumes while they are both in the library and
system-managed. DFSMSrmm duplicate volume support allows you to have
different barcoded labels on volumes that have the same VOL1 label volume serial
number.
TotalStorage Automated Tape Library (3495) System Attachment
The IBM TotalStorage Enterprise Automated Tape Library (3495) is attached to host
systems by a communications path to an IBM 3490 or 3490E control unit with the
addition of a library attachment facility feature. The feature provides a
microprocessor card and attachment cable for connection of each 3490 or 3490E
control unit path to the library manager application. The equivalent of the library
attachment facility is built into the control unit for an IBM 3590. See “TotalStorage
Automated Tape Library (3494) System Attachment” on page 11 for more
information concerning these systems.
The ATLDS (see Figure 1 on page 10) is capable of supporting multiple control
units and tape drives. The details for each callout in Figure 1 on page 10 are
explained in the text that follows. See Table 3 on page 44 for more information
concerning configuration capabilities, and “TotalStorage Automated Tape Library
(3494) System Attachment” on page 11 for more details concerning the tape
systems. For more detailed information regarding the hardware features of the IBM
TotalStorage Enterprise Automated Tape Library (3495), see 3495 Tape Library
Introduction and Planning Guide.

Figure 1. IBM TotalStorage Enterprise Automated Tape Library (3495)
High Capacity Input and Output Facility
All 3495 ATLDS models can have an optional high-capacity input and output
facility (Figure 1, item 1) that reserves a section of the cartridge storage area to
be used for input and output of large numbers of cartridges. This optional facility
requires that the tape library be placed in paused mode (indicating that the cartridge
accessor is not active) while the areas are being loaded and unloaded. The software
term for the process of ejecting cartridges into the high-capacity output station is
known as bulk eject, and the software term for the process of entering cartridges
into an automated tape library dataserver using the high-capacity input station is
known as bulk entry.
External High-Capacity Input and Output Facility
The optional external high-capacity input and output station feature (not shown in
Figure 1) allows the operator to add or remove up to 240 cartridges from the IBM
TotalStorage Enterprise Automated Tape Library (3495) without pausing automated
operations or without the operator entering the 3495 enclosure.
Note: If the external high-capacity input and output station feature is installed, the
high-capacity input and output facility cannot be enabled.
Manual Mode Terminal
A manual mode terminal (Figure 1, item 2) is located in the enclosure of the tape
library and is used to assist the operator with manual mode operations when the
10
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
cartridge accessor is not active. The library manager uses the manual mode
terminal to inform the operator which volumes to mount and eject, and where to
locate the volumes in the storage cells.
Library Manager Application
The library manager (Figure 1 on page 10, item 3) is a licensed internal code
application installed in the library controller that controls all operations in the tape
library. The library manager controls tape library automation, communicates with
the host through each control unit, and allows communication paths for operators
and service personnel. The library manager is also used for service and test
sessions and provides operator status information and control panels for the
operator’s use. Transaction logs and an error log are also provided as problem
determination aids. For more information concerning the library manager for the
3495, see the 3495 Tape Library Introduction and Planning Guide .
Commands are processed by the library manager and translated into requests for
cartridge movement or database processing. The library manager database
provides a cross-reference between a volume serial number, a volume’s actual
storage location, and a volume’s category. See “Displaying Tape Volume Status” on
page 133 for a list of valid volume categories and their descriptions.
Convenience Input and Output Facility
Each tape library has a convenience input and output station (Figure 1 on page 10,
item 4) for inserting cartridges into and ejecting cartridges from the tape library,
without requiring the pausing of automated operations or operator entry into the
tape library enclosure area. Each convenience input and output station has a
capacity of 20 cartridges.
For more information on these hardware features, see 3495 Tape Library Introduction
and Planning Guide.
TotalStorage Automated Tape Library (3494) System Attachment
The IBM TotalStorage Enterprise Automated Tape Library (3494) (Figure 2 on page
12) can be attached to host systems by two methods. The first method is
attachment to host systems through a communications path to the control unit of
an IBM 3490E, an IBM 3590, an IBM 3592, or a combination thereof. The second
attachment method stems directly from the library manager to open systems hosts
through a host attachment feature. This attachment provides direct communication
between the open system host and the 3494 library manager.
The details for each callout in Figure 2 on page 12 are explained in the text that

Tape Systems
The 3494 uses the 3490E Magnetic Tape System, the IBM TotalStorage Enterprise
Tape System 3590, and the IBM TotalStorage Enterprise Tape System 3592,
individually or in combination (Figure 2, item 3). Each system has its own
integrated control unit. The 3490E models can read cartridges written by other
3480 and 3490 base models. For more information concerning the IBM 3490E
models, see IBM 3490E Tape Subsystem Installation, Planning, and Operator's Guide.
The IBM TotalStorage Enterprise Tape System 3590 Model B is capable of
coexisting with 3490 and 3490E devices in the IBM TotalStorage Enterprise
Automated Tape Library (3495). The 3490E Magnetic Tape System, the IBM
TotalStorage Enterprise Tape System 3590 Model B, Model E, and Model H, the
12
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
IBM TotalStorage 3592 Model J, the IBM TotalStorage 3592 Model E05, and the IBM
TotalStorage 3592 Model E06 are all capable of coexisting in the same IBM
TotalStorage Enterprise Automated Tape Library (3494). With native fibre
connection (FICON®) attachment, the controllers can provide even greater
improvements in tape performance and attachment distance.
The IBM TotalStorage Enterprise Tape System 3590 Model E and Model H, and the
IBM TotalStorage Enterprise Tape System 3592 Model J, Model E05, and Model E06
are supported in the IBM TotalStorage Enterprise Automated Tape Library (3494)
and in the Manual Tape Library (MTL) in 3590-1 emulation mode only. Inside an
IBM tape library, the SMS tape software support recognizes the 3590-1 emulated
devices by their real device types rather than by the drives they are emulating.
This enables 3590 Model B, Model E, Model H, the 3592 Model J, Model E05, and
Model E06 devices to coexist in the same library.
The 3590 Model E and Model H can read cartridges written by the 3590 Model B.
The 3590 Model H can also read cartridges written by the 3590 Model E. The 3590
tape systems use the IBM High Performance Cartridge Tape (MEDIA3) and the
IBM Extended High Performance Cartridge Tape (MEDIA4). The 3592 tape systems
model use the IBM Enterprise Tape Cartridge (MEDIA5), the IBM Enterprise
WORM Tape Cartridge (MEDIA6), the IBM Enterprise Economy Tape Cartridge
(MEDIA7), and the IBM Enterprise Economy WORM Tape Cartridge (MEDIA8).
The 3592 Model E05 and Model E06 also uses two additional media types, the IBM
Enterprise Extended Tape Cartridge (MEDIA9) and the IBM Enterprise Extended
WORM Tape Cartridge (MEDIA10). The 3592 tape systems cannot read cartridges
written by the 3590 tape systems, nor can the 3590 tape systems read any
cartridges written by the 3592 tape systems.
The 3590 and 3592 expand the storage capabilities and performance for these
libraries by providing higher performance, a larger capacity cartridge, and
increased reliability over previous tape systems.

Convenience Input and Output Station
The convenience input/output station (Figure 2 on page 12, item 4) is an
optional feature on the 3494 that is used for inserting cartridges into or ejecting
cartridges from the ATLDS, without interrupting normal automated operations. For

High Capacity Input/Output Facility
The high-capacity input/output facility (not shown) is an option that reserves a
section of the cartridge storage area to be used for the input/output of cartridges.
Either a high capacity output facility or a high capacity input/output facility can
be defined, but not both.
Library Manager Application
The library manager (Figure 2 on page 12, item 1) is a licensed internal code
application installed in the library controller that controls all operations in the tape
library. The library manager communicates with the host through each control unit,
and allows communication paths for operators and service personnel. The library
manager is also used for service and test sessions and provides operator status
information and control panels for the operator’s use. Transaction logs and an
error log are also provided as problem determination aids. For more information
concerning the library manager for the 3494 ATLDS, see IBM TotalStorage Enterprise
Automated Tape Library (3494) Introduction and Planning Guide.
System Storage Automated Tape Library (3584) System Attachment
The IBM System Storage™ 3584 Tape Library TS3500, with the added 3953 Library
Manager, enables the open systems SCSI medium changer library to be connected
and used by zSeries® attached hosts. The 3953 Library Manager provides
capabilities similar in functionality to the 3494 Library Manager. As with the 3494
automated tape library, the 3584 tape library can be shared by multiple operating
system platforms (open systems and System z® attached hosts) and can be
partitioned across multiple System z hosts. However, the 3584 tape library
supports only the 3592 tape drive technology and the Virtual Tape Server (VTS),
unlike the 3494 tape library, which supports (by System z attachment) the 3490E,
3590 and 3592 native tape drive technologies as well as the VTS. For more detailed

Virtual Tape Server system of the ATLDS
The virtual tape server (VTS) system (not pictured) in an ATLDS combines the
random access and high performance characteristics of DASD with outboard
hierarchical storage management and virtual tape devices and virtual tape
volumes, providing significant reductions in the number of physical cartridges,
devices, and automated libraries needed to store customer data.
The key concepts of this system are as follows:
v Emulating 3490-type tape devices (virtual devices)
v Emulating 3490-type tape volumes (virtual volumes)
v Import and export functions
v Tape volume cache
v Storage management of the tape volume cache
v Improved cache management
v Deleting expired virtual tape server logical volume data
v Maintaining data fragments from migrated volumes
v Fast response for nonspecific mount requests

Emulating 3490-Type Virtual Tape Devices
From a host perspective, the virtual system looks like multiple 3490E control units,
each with 16 tape devices. Each emulated device is called a virtual tape device.
The virtual system handles all 3490 tape commands. Each virtual device has the
following attributes:
v Has a host device address
v Is included in the I/O generation for the system
v Is varied online or offline to a host
v Signals ready when a virtual volume is loaded
v Responds to and processes all 3490E tape commands
v Becomes not ready when a virtual volume is rewound and unloaded
v Indicates that it has a cartridge loader
v Can be associated with a pool of scratch volumes that allow very fast mount
access for scratch mounts
Note: The active status of the cartridge loader depends on the availability of
scratch volumes in the assigned pool.
Data is written and read as if it is stored on a real Standard or Enhanced Cartridge
System Tape; however, within the system it is really stored on DASD. All tape read
and write commands are translated to read and write data records to or from
DASD. Volumes residing on the DASD are called virtual volumes. For more
information concerning virtual volumes, see “Emulating 3490-Type Virtual
Volumes.”
All host interactions with data in a VTS are through virtual volumes and
associated virtual tape devices; there is no direct access to the data on a physical
cartridge or device.
Emulating 3490-Type Virtual Volumes
The virtual tape server (VTS) system in a 3494 or 3584 ATLDS uses virtual volumes
for all interactions with host software. When these virtual volumes and the data
associated with them are being used by the host system, they are stored in the tape
volume cache, not on a physical tape device or volume. For more information on
tape volume cache, see “Tape Volume Cache” on page 17 and see IBM TotalStorage
Enterprise Automated Tape Library (3494) Introduction and Planning Guide. These
virtual volumes emulate the functional characteristics of a cartridge system tape.
Each virtual volume has the following attributes:
v Has a unique volume serial number
v Is loaded and unloaded on a virtual device
v Supports an IBM Standard Label
v Can be appended to after having been initially written from the beginning of the
tape
v Has an advantage over a physical volume because the mount response time for
a virtual volume request, specific (when in cache) or nonspecific, is faster, since
there is no dependency on the physical movement of a cartridge or the loading
delays of a physical drive
Chapter 1. Introduction to Tape Library Management
15
The tape volume cache of the virtual tape server enables the utilization of the 3590
and 3592 tape technology. When a virtual volume is copied from the tape volume
cache to a native cartridge, the volume then becomes a logical volume. A native
cartridge that contains logical volumes is referred to as a stacked volume. The VTS
stacks multiple host-created volumes onto a native cartridge to create a stacked
volume. The native library volumes used for stacking are identified through their
volume serial numbers.
When a native cartridge identified as a stacked volume is inserted into a library, it
becomes part of the volumes managed by the VTS and is not reported to the host
as a newly inserted volume. Only the logical volumes specified at the library
manager console are reported to the host. By buffering host created volumes, then
later stacking them on a native cartridge, the cartridge capacity of the native
technology is fully utilized. The cartridges used with this volume stacking
technology emulate Cartridge System Tape or Enhanced Capacity Cartridge System
Tape to the host system. When a logical volume is moved from a native cartridge
to the tape volume cache, the volume becomes a virtual volume again.
Larger Logical Volume Sizes
By default the VTS supports two logical volume sizes 400 MB and 800 MB which
correspond to the supported 3490 media types: cartridge system tape (MEDIA1)
and enhanced capacity cartridge system tape (MEDIA2). Using outboard policy
management support, the default volume size can be overridden at the library
through a data class policy specification. If a maximum volume size is specified in
the assigned data class, that volume size will override the default volume size for
the volume when it is first mounted. A logical volume's maximum volume size can
then change when it is mounted as a scratch volume again. However, for TS7700
Virtualization Engine Release 1.6 or later, the logical volume's maximum size can
change when the volume is written from load point, for either a scratch or private
(specific) request. Prior to Release 1.6, the TS7700 retained the capacity of the
logical volume (on reuse), unless the volume was mounted as a scratch volume.
For additional information on the supported logical volume sizes, refer to the
applicable tape library operator guide. In addition to this, application
configuration-related changes may also be needed to fully utilize the larger logical
volume sizes (TAPEPERCENTFULL or TAPECAPACITY-type specifications).
Starting with Release 1.4 of the TS7700 Virtualization Engine (and only the TS7700
Virtualization Engine), support was put in place for the host (and associated
applications) to obtain the logical volume size from the library. Refer to the
applicable application-related documentation, for any added support in this area.

VTS System Import and Export Functions
The virtual tape server (VTS) system provides the ability to physically import
(enter) and export (remove) logical volumes within the VTS. This support includes
managing the physical removal of the native cartridges containing stacked logical
volumes from a VTS and the corresponding function for entering these cartridges
into a VTS. These functions require interaction with the host and the tape
management system software. See “Exporting Logical Volumes from a 3494 VTS
System” on page 37 and “Importing Logical Volumes into a 3494 VTS System” on
page 29 for more information.
See “Import/Export Considerations for the 3494 VTS” on page 70 for information
on coexistence considerations for the VTS import and export functions, particularly
for outboard policy management support implications.

z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Tape Volume Cache
The tape volume cache consists of a high performance array of DASD and storage
management software. Virtual volumes are held in the tape volume cache when
they are being used by the host system. Outboard storage management software
manages which virtual volumes are in the tape volume cache and the movement of
data between the tape volume cache and physical devices. The size of the DASD is
made large enough so that more virtual volumes can be retained in it than just the
ones currently associated with the virtual devices.
After an application modifies and closes a virtual volume, the storage management
software in the system makes a copy of it onto a physical tape. The virtual volume
remains available on the DASD until the space it occupies reaches a predetermined
threshold. Leaving the virtual volume in the DASD allows for fast access to it
during subsequent requests. The DASD and the management of the space used to
keep closed volumes available is called tape volume cache. Performance for
mounting a volume that is in tape volume cache is quicker than if a real physical
volume is mounted.
Storage Management of the Tape Volume Cache
Storage management software in the system manages the contents of the tape
volume cache. Virtual tape volumes are migrated from the tape volume cache to
physical tape when they are no longer needed for fast access and recalled from
tape to the tape volume cache when they are again requested to be mounted. The
storage management software stacks multiple migrated files onto a native tape,
thereby utilizing its storage capacity. For more information on this volume stacking
concept, see “Emulating 3490-Type Virtual Volumes” on page 15.
Improved Cache Management
Improved cache management enables you, through your installation's ACS
routines, to select a cache preference group of 0 or 1. You can use the storage class
initial access response time (IART) parameter at the host to select the preference
group. If the value specified in this parameter is greater than or equal to 100, the
logical volume is associated with cache preference group 0. If the value specified is
less than 100, the logical volume is associated with cache preference group 1,
which is also the default. When space is needed in the cache, logical volumes
associated with preference group 0 will be removed from the cache before logical
volumes associated with preference group 1. Volumes are removed from preference
group 0 are based on their size, with the largest volumes being removed first.
Volumes continue to be removed from preference group 1 based on a least recently
used algorithm. Data written to the VTS for backup or long-term archival purposes
can assign a storage class that specifies an initial access response time parameter
greater than or equal to 100.
With outboard policy management support, you can define the cache preference
level at the library through the library manager storage class policy, rather than
through the IART parameter. The outboard specification overrides the host IART
specification if you have defined a cache preference level setting in the library
manager policy construct definition. If the outboard construct was automatically
created and was defined with no cache specification, the host IART specification is
used. If there is no IART specification, then the default preference level of 1 is used
for the volume.
|
|
With Release 1.6 of the TS7700 Virtualization Engine, you can use the LIBRARY
REQUEST command at the host to temporarily override (while the volume is in
Chapter 1. Introduction to Tape Library Management
17
cache) a volume’s preference group assignment, causing the volume to remain in
cache longer or to be removed from cache sooner. Refer to “Requesting
Information from the TS7700 Virtualization Engine” on page 108 for information on
the LIBRARY REQUEST command.

Deleting Expired Virtual Tape Server Logical Volume Data
Logical volumes in a VTS are stored on physical stacked volumes after the host
closes the logical volumes. Without the deletion of expired VTS logical volume
data, the data that represents the contents of a logical volume on a physical
stacked volume is not expired from the VTS point-of-view until the logical volume
is rewritten or otherwise modified. This causes the VTS to continue managing the
data as if it were still active, even though the user has actually scratched it. These
“user-expired” logical volumes are maintained as active data by the VTS during
reclaim processing. These volumes also needlessly consume physical stacked
volume resources, thus requiring more physical stacked volumes in a VTS.
The deletion of expired logical volume data eliminates the need for the VTS to
manage logical volume data that has already been expired at the host. At the same
time, it provides a “grace period” during which the VTS continues to manage the
data after the host has expired the data. The deletion times are associated with
categories that have the Fast Ready attribute.
Additionally, a "hold" setting can also be associated with categories that have the
Fast Ready attribute to restrict the usage of volumes with an unexpired expire
time. Restricted volumes cannot be used to satisfy a mount request and cannot be
moved to a different category until their expire time duration has elapsed. Since
volumes with an unexpired expire time cannot be used to satisfy a mount request,
they are also excluded from the scratch volume category count in the DISPLAY
SMS,LIBRARY command.
See IBM TotalStorage Enterprise Automated Tape Library (3494) Operator’s Guide for
more information on defining the Fast Ready categories.
Secure Data Erase
The secure data erase support guarantees that logical volume data that has expired
in the VTS cannot be recovered by any reasonable means once the physical volume
where the data resided has been reclaimed. The secure data erasure function is
enabled on a physical volume pool basis when a non-zero value is specified for the
secure data erase reclaim policy. For additional information on using this support,
see IBM TotalStorage Enterprise Automated Tape Library (3494) Operator’s Guide.
Maintaining Data Fragments from Migrated Volumes
When a virtual tape volume is no longer needed in the tape volume cache, the
data it represents is not completely removed. A fragment of the data is kept on
DASD. The data fragment includes information about the migrated virtual volume
so that it can be recalled and it also includes the first several records from the last
use of the volume.
Fast Response for Nonspecific Mount Requests
When a nonspecific mount is requested, data is written from the beginning of the
tape, overwriting any existing data on the tape. Within a VTS system, a nonspecific
mount request is satisfied by accessing the data fragment in the tape volume cache
associated with the virtual volume selected by the library manager to satisfy the
request. No recall of the data from the previous usage of the volume is performed
18
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
because the fragment contains the label information needed by the host tape
management software to validate the use of the volume for a nonspecific mount
request. The system signals the host that the mount is complete when the fragment
is accessed. The result is a very low mount response time because no physical
movement or mounting of a cartridge is involved.
Using the 3590 and 3592 Storage Capacity
One of the key features of the VTS is its capability to automatically use the 3590
and 3592 tape technology cartridge storage capacity. With a VTS, volumes being
created by the host applications are stored in a tape volume cache which is built
from DASD devices. The size of the tape volume cache is greater than the capacity
of a native cartridge. The tape volume cache can potentially contain hundreds of
tape volume images called virtual volumes, depending on the size of the volumes
and tape volume cache. Through tape volume cache management policies, the VTS
moves virtual volumes from the tape volume cache to a native cartridge managed
by the VTS system. As virtual volumes are moved from the tape volume cache,
they are stacked end to end on the cartridge and take up only the number of bytes
written by the host, effectively using all of the storage capacity of the cartridge.
Logical Library Partitioning
To support the requirement that virtual tape server systems coexist with native
tape systems in the same library, the library manager partitions the physical library
into logical libraries: one library for each VTS system (a physical library can contain
up to two VTS systems) and another that contains all other systems. This must be
done because a virtual tape server system presents the image of 3490-type tape
device and yet cannot read or write a real 3490 cartridge. By placing a virtual tape
server system in its own logical library, host software will not be able to attempt to
allocate a virtual tape server device for a real 3490 mount, and likewise, the other
way around.
A logical library can contain:
v A single virtual tape server system
v The native tape systems
Each logical library will have its own unique library sequence number and will
look like a separate physical library to the hosts attached to the system in that
partition. The physical assets used by the system are managed by the library
manager in the library.
Operator Interface
The library manager console is used to perform the setup, management, and status
functions needed to support a VTS system.
Logical Volume Inventory
The database in the library manager is expanded to handle the large number of
logical volumes that a VTS system uses. There are also operator functions that
allow you to add logical volumes by specifying a volume serial number range
through the library manager console.
For more information concerning the usage, configuration, and characteristics of
the virtual tape server, see IBM TotalStorage Enterprise Automated Tape Library (3494)
Introduction and Planning Guide.
Chapter 1. Introduction to Tape Library Management
19
Physical Volume Pooling
Using outboard policy management support, you can manage logical volumes
much more easily and efficiently by grouping volumes that have common
characteristics on a set of physical stacked volumes, providing volume affinity. This
group of stacked volumes is known as a physical volume pool. Common
characteristics can include expiration dates, off-site disaster recovery data, backup
copies, and so on. Physical volume pooling provides your installation with the
following capabilities and benefits:
v It allows you to accurately charge for storage management services that is based
on the number of physical stacked volumes that are allocated for a particular
enterprise.
v It ensures that you can reserve groups of physical media for specific uses or
owners.
v It enhances adherence to security policies by grouping data for different
divisions or areas of an enterprise.
Use the library manager storage group policy construct to assign logical volumes
to physical stacked volumes and to group sets of stacked volumes into physical
volume pools. The VTS system writes the logical volumes that are assigned to this
storage group to the set of physical volumes that are assigned to the physical
volume pool.
If you do not specify a physical volume pool in the library manager storage group
policy construct, the VTS system writes the volumes to the common scratch pool.
If you update the library manager storage group policy construct to allow for the
assignment of logical volumes to a specific physical volume pool, the VTS does not
move the data to the specified pool until the next time you rewind and unload the
logical volume from the tape drive.
Selective Dual Copy
Using outboard policy management support, the library can make a second copy
of a logical volume and assign it to a secondary physical volume pool. This
function is supported in both the stand-alone and in the Peer-to-Peer VTS library.
In a Peer-to-Peer VTS, a second copy is made in each distributed library. Because
placing a second copy of a logical volume on the same physical media as the
primary copy risks the integrity of the data, this support allows you to place the
second copy of the logical volume on a physical volume associated with this
secondary volume pool. This helps eliminate physical media as a single point of
failure.
Use the library manager management class policy construct to make a second copy
of a logical volume and assign it to a secondary physical volume pool. The VTS
system writes the second copy of the volume to the secondary volume pool that
you designate.
If you do not predefine the management class policy construct at the library and
the VTS system automatically assigns default actions to the policy, the system does
not perform the selective dual copy function. The default action is to make only a
primary copy of the logical volume. It is not to create a second copy of the volume
in the VTS. If you update the management class policy construct to make a second
copy of the volume, the VTS does not make the second copy retroactively. The
action of creating the second copy occurs the next time you rewind and unload the
logical volume from the tape drive.

z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Bulk Volume Information Retrieval
The outboard Bulk Volume Information Retrieval (BVIR) facility allows a host job
to request and obtain information about all of the logical volumes managed by a
virtual tape server (VTS), including a Peer-to-Peer VTS. Within a VTS, a database is
maintained that contains information about the state and data validity of each
logical volume. This function uses a logical volume to allow a batch job to request
information from the VTS. When the logical volume is mounted, the VTS formats
the requested information onto the volume as an IBM standard labeled tape
volume containing a single file. The file contains multiple records, one for each
logical volume in the VTS. Because it is standard volume format, the data is
accessible through standard host utilities such as IEBGENER. Physical–to–logical
volume mapping is just one example of the information you can obtain with this
facility. For additional information on using this facility, refer to the following IBM
Whitepapers: IBM Virtualization Engine TS7700 Series Bulk Volume Information
Retrieval User's Guide and IBM TotalStorage Virtual Tape Server 3494 Bulk Volume
Information Retrieval Function User's Guide.
Peer-to-Peer Virtual Tape Server
The IBM TotalStorage Enterprise Peer-to-Peer Virtual Tape Server addresses data
availability, system availability, remote copy and data vaulting desires for the VTS
family. Virtual Tape Controllers exist between MVS hosts and the virtual tape
servers to provide replication, transparent tracking, and synchronization of the
Logical Tape volumes. The Peer-to-Peer VTS provides multiple copies of all tape
data.
The Peer-to-Peer VTS system supports an immediate or deferred copy option. In
deferred copy mode, the library schedules creation of the copy upon receiving the
rewind/unload command from the host. The copy is then made in the background
as VTS activity permits. In immediate copy mode, the copy is started upon
receiving the host rewind/unload command and signals completion of the
rewind/unload command when the copy operation is complete.
The Peer-to-Peer VTS system appears as one library image to the attached hosts.
The single library image is referred to as the composite library. The underlying
physical VTS libraries that make up the composite library are referred to as the
distributed libraries. All three libraries (the composite library and two distributed
libraries) will be defined to the host, whereas the drives and volumes will be
defined and associated with the composite library.
The composite library will reflect the overall state of the VTS systems, with
individual library status being reflected through the distributed libraries. For
example, if one of the distributed libraries is in paused mode and the other is in
automated mode, the overall status of the VTS composite library will be automated
with messages to the host indicating which of the distributed libraries is paused. If
one of the distributed libraries is taken offline at the library, the state of the
composite will remain online and operational as long as one of the distributed
libraries is operational.
Note: The Import/Export feature is not supported in a Peer-to-Peer VTS system.
Geographically Dispersed Parallel Sysplex Support for
Peer-to-Peer VTS
The Geographically Dispersed Parallel Sysplex™ (GDPS®) integrates Parallel
Sysplex® technology and remote copy technology to enhance application
Chapter 1. Introduction to Tape Library Management
21
availability and improve disaster recovery. GDPS topology is a Parallel Sysplex
cluster distributed across two sites, with all critical data mirrored between the sites.
GDPS manages the remote copy configuration and storage systems, automates
Parallel Sysplex operational tasks, and automates failure recovery from a single
point of control, thereby improving application availability. GDPS supports all
transaction managers (for example, Customer Information Control System [CICS]
and Information Management System [IMS]) and data base managers (for example,
DB2®, IMS™, and Virtual Storage Access Method [VSAM]).
The Peer-to-Peer VTS allows GDPS to include tape data in its management of data
consistency and integrity across sites. A new I/O VTS selection option is provided
for use with GDPS such that all virtual volumes are processed from a primary VTS
and a copy is stored on the secondary VTS. GDPS has the control capability to
“freeze” copy operations so that tape data consistency can be maintained across
GDPS-managed sites. Additionally, GDPS can switch the primary and secondary
VTSs, and synchronize system data sets such as catalogs, TCDB, and tape
management databases with the Peer-to-Peer VTS after an emergency switchover.
The physical topology of a GDPS consists of a base or Parallel Sysplex cluster
spread across two sites, with one or more z/OS systems at each site. GDPS uses
the Parallel Sysplex cluster facilities to communicate between the systems. Each
GDPS system joins the GDPS Parallel Sysplex cluster group. When a system joins a
Parallel Sysplex cluster, GDPS automation will transfer GDPS policy and all GDPS
status to the joining system.
If your installation is running Peer-to-Peer VTS under GDPS, take into account the
considerations that are shown in Table 1 for your particular environment:

Selective Peer-to-Peer Copy Mode
Using outboard policy management support, you can specify whether a
Peer-to-Peer VTS makes a copy of a logical volume immediately or defers the copy
operation to a later time. This is known as selective peer-to-peer copy mode. It allows
greater flexibility in allocating system resources. This function overrides, on a
volume-by-volume basis, the existing copy mode setting.
Use the library manager management class policy to specify whether a volume’s
copy is made with the immediate or deferred copy mode.
If you do not predefine the management class policy construct at the PtP VTS
library and the VTS system automatically assigns default actions to the policy, the
selective peer-to-peer copy mode uses the current copy mode setting. If you update
the management class policy construct to make an immediate or deferred copy of
the volume, that management class policy setting overrides the current setting the
next time the volume is written.
Selective Peer-to-Peer Dual Copy
Using outboard policy management support, you can also specify whether a
Peer-to-Peer VTS makes a copy of the logical volume in each distributed library.
On a volume-by-volume basis, you can indicate which distributed VTS library is to
be used as the I/O VTS and whether the data written is to be copied to the other
VTS. Use the library manager management class policy to specify which
distributed VTS library should be the I/O VTS and to specify the "no copy" option.
TS7700 Virtualization Engine
The IBM System Storage Virtualization Engine TS7700 provides tape virtualization
capabilities for the System z environment and is the successor to the IBM Total
Storage 3494 Virtual Tape Server (VTS) and the IBM TotalStorage 3494 Peer-to-Peer
VTS (PtP VTS). Members of the TS7700 product family include the TS7740
Virtualization Engine (3957-V06) and the disk-only TS7720 Virtualization Engine
(3957-VEA). Unless stated otherwise, references to the TS7700 Virtualization Engine
apply to both the TS7740 and the TS7720. In addition to the following sections, for
Chapter 1. Introduction to Tape Library Management
23
more information on the TS7700 Virtualization Engine, refer to the IBM Redbook
IBM System Storage Virtualization Engine TS7700: Tape Virtualization for System Z
Servers.
Note: In general, references throughout this document to the terms "VTS" and
"Peer-to-Peer VTS" also apply to the TS7700 Virtualization Engine. In
general, the TS7700 Virtualization Engine uses the existing 3494 VTS and PtP
VTS support that is in place at the host. However, with specific releases of
the TS7700, explicit host support is added. For TS7700 Release 1.3 refer to
APAR OA20065 (z/OS V1R6 and above), for TS7700 Release 1.5 refer to
APAR OA24966 (z/OS V1R8 and above), and for TS7700 Release 1.6, refer to
APAR OA28632 (z/OS V1R9 and above).

TS7740 Virtualization Engine (3957-V06)
The TS7740 Virtualization Engine, displayed by the host as a 3957-V06, utilizes
virtual and physical tape drives, disk cache, and integrated hierarchical storage
management to provide a data storage solution. The TS7740 Virtualization Engine
expands upon the capabilities provided by the 3494 VTS and the Peer-to-Peer VTS.
The TS7740 Virtualization Engine (each known as a cluster) can be interconnected
to form a grid configuration. Using advanced policy management, also referred to
as outboard policy management, you can create policies to perform tasks such as
creating a secondary copy of data, creating one or more copies across a grid
network, and controlling physical volume pooling. This solution provides high
availability, disaster recovery, and disaster recovery testing capabilities.
A grid configuration presents itself to the attached hosts as a single library image
with 3490-E emulated virtual tape devices. The copying of the volumes in a grid
configuration is handled by the clusters and is completely transparent to the host.
Each TS7740 Virtualization Engine in a grid manages its own set of physical
volumes and maintains the relationship between logical volumes and the physical
volumes on which they reside.
The TS7740 Virtualization Engine is supported by the host similarly to the
Peer-to-Peer VTS. The TS7740 Virtualization Engine appears as one library image
to the attached hosts. The single library image is referred to as the composite
library, the logical image of the grid. The underlying clusters of the composite
library are referred to as the distributed libraries. As with the Peer-to-Peer VTS, all
drives and volumes are associated with the composite library with the distributed
libraries being used to report on the state of each library. A stand-alone TS7740
Virtualization Engine (single cluster grid) is a grid consisting of one cluster. Even
though the single cluster grid consists of one VTS (distributed library), this is
different from the standalone VTS, and requires that a composite library and a
distributed library be defined at the host in order to represent the TS7740
Virtualization Engine. Multiple TS7740 Virtualization Engines (multi-cluster grid)
form a grid consisting of multiple clusters, and to the host, consists of one
composite library and multiple distributed libraries. All the libraries (composite
and distributed) must be defined to the host.
TS7720 Virtualization Engine (3957-VEA)
|
The TS7720 Virtualization Engine, displayed by the host as a 3957 Model VEA, is
similar in concept to the TS7740; however, what makes it different is that it
provides support for a disk-only solution. The TS7720 is a virtual tape solution that
has no back-end physical tape. Because all of the data written to the TS7720
Virtualization Engine resides in cache, the TS7720 supports larger amounts of cache
than the TS7740. The TS7720 is also supported in a multi-grid configuration and
|
|
|
|
|
|
24
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
|
|
|
starting with Release 1.6 of the TS7700, the clusters in a grid can be heterogeneous
(TS7720 and TS7740), referred to as a hybrid configuration. Like a TS7740, the
TS7720 is also defined to the host using composite and distributed libraries.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
When the TS7720 detects that available cache space has fallen below preset
thresholds, the TS7720 sends CBR3792E (limited cache free space warning state
reached) and CBR3794A (out of cache resource critical state reached) attention
messages to the attached hosts. The CBR3792E message can be used to trigger
return to scratch processing or the copying of data to another library. If the amount
of available cache subsequently reaches the critical state, all fast ready (scratch)
mounts are failed and any specific mount operations are allowed; however, any
attempt to write to the volume will be failed. Mount operations that have been
accepted before entering this state complete and volumes currently mounted can
continue to perform host I/O operations. As appropriate, the VARY SMS,STORGRP
operator command can also be used to steer scratch allocations to another
composite library that is eligible for the scratch request. The DISPLAY
SMS,LIBRARY command with DETAIL, can also be used periodically to display
the "CACHE PERCENTAGE USED" in a distributed library.
|
|
|
|
|
|
|
|
|
|
To assist with the cache management in a TS7720, having a TS7740 Virtual Engine
in the multi-cluster grid configuration (hybrid configuration) provides an
additional back-end tape capability. To manage the migration of data from the
TS7720 to the TS7740, with Release 1.6 of the TS7700, there is a ‘Volume Removal
Policy’ at the library. Since the TS7720 has a finite amount of cache, once that cache
fills, this policy allows logical volumes to be automatically removed from cache
while a copy is retained elsewhere in the grid. This copy could exist on physical
tape associated with a TS7740 or in another TS7720 tape volumes cache. When
coupled with copy policies, this provides an automatic data migration function
between the clusters in the grid.

Logical WORM Considerations
|
|
|
|
|
|
|
|
|
|
|
|
|
Support for logical WORM is provided with Release 1.6 of the TS7700
Virtualization Engine (for both the TS7740 and the TS7720). Refer to APAR
OA28632 (z/OS V1R9 and above) for additional detail. If the TS7700 is a
multi-cluster grid, all clusters in the grid must be at a release level that supports
logical WORM for the TS7700 to be WORM enabled. To request a logical WORM
volume, an outboard data class policy must be defined (at the library) requesting
logical WORM. This data class must then be assigned through the ACS routines,
for a logical WORM request. A logical volume will become WORM when it is first
mounted and written from load point. A volume will not take on the WORM
attribute if user data had already been written to the volume. Also, when a dataset
written to a WORM volume extends to another volume (EOV processing), the next
volume in the chain will also be WORM. This is handled through the existing
advanced (outboard) policy management support.
|
|
|
|
|
|
|
|
|
|
As with the 3592 physical WORM tape support, any attempt by the host to modify
a previously written user data record of a logical WORM volume will be failed by
the TS7700. With the 3592 WORM tape support, a volume is designated as WORM
through usage of special WORM media types (MEDIA6, MEDIA8 and MEDIA10).
A logical volume (MEDIA1 or MEDIA2) will be designated as WORM, not by the
usage of a special WORM media type, but when it is first mounted and written
from load point (and associated with a data class policy that has WORM
functionality enabled at the library). As with the 3592 WORM tape support, a
logical WORM volume is assigned a world-wide unique identifier (WWID) and is
associated with a write mount count (WMC). During the mount, the TS7700
Chapter 1. Introduction to Tape Library Management
25
assigns a WWID and WMC to the volume. Once a logical WORM volume has
expired, to be consistent with physical WORM and the special release actions that
may be in place by the tape management system, for the logical volume’s VOLSER
to be reused, it must be returned to scratch and the reuse of the volume (as either
WORM or rewritable (R/W)) must then occur as a scratch (category) mount. If the
volume is subsequently reused as logical WORM, the library will create a new
WWID and WMC for this new instance of the volume. If, instead, the expired
WORM volume’s VOLSER is to be reused (from load point) by specific mount (and
not by scratch mount), the volume must first be moved to scratch and ejected
“purged” from the library. At that time, the volume can then be entered (as a new
logical volume) into the library as private and used as either WORM or rewritable
(R/W). Also, once a previously used R/W volume has expired, to be reused as
logical WORM, it must also go through the logical WORM steps above if the
volume is to be mounted by specific VOLSER (and not by scratch mount). In
summary, a logical volume can become WORM when it is mounted as a scratch
volume (category mount) or mounted by specific volser and the volser referenced
is considered a new logical volume. Refer to your tape management system for its
usage of the WWID and the WMC and for its handling of expired logical WORM
volumes.

TS7680 Tape Virtualization
|
|
|
|
|
|
|
The IBM System Storage TS7680 ProtecTIER Deduplication Gateway is designed to
deliver a high performance inline data deduplication solution on System z. Like
the IBM System Storage TS7720 Virtualization Engine, the TS7680 provides a
disk-only virtual tape solution. The TS7680 emulates an IBM tape library and 3592
Model J1A tape drives. The TS7680 appears to the host as an automated tape
library (AL) and not as a virtual tape library (VL) and, is displayed as a 3958-DE2
by the DISPLAY SMS,LIBRARY command.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
For high availability, the TS7680 supports two nodes, with each node consisting of
an enterprise tape control unit and deduplication engine. Each node supports up to
128 virtual tape devices (8 logical control units with 16 devices per logical control
unit) and emulates the IBM System Storage 3592 Model J1A tape drive and JA
(MEDIA5) media for a maximum configuration supporting up to 256 devices. Even
though the library supports up to 256 virtual tape devices, based on the size of the
backend disk repository, only a subset of the drives may be supported (refer to the
TS7680 product documentation for any configuration-related requirements).
Devices in the first (lower) tape control unit are defined using subsystems X'01'
through X''08' and devices in the second (upper) tape control unit are defined
using subsystems X''11' through X'18'. With the TS7680, one tape controller or
deduplication engine can be offline (for code upgrade or repair) and, with a shared
disk cache, all logical volumes are accessible through the remaining node’s virtual
device addresses.
|
|
|
|
|
|
|
|
The capacity of a TS7680 logical volume is less than a traditional JA (MEDIA5)
physical cartridge (100 GB versus 300 GB). Performance scaling and performance
segmentation, which are options with physical JA (MEDIA5) media, are not
supported with the TS7680 and will be ignored. The host's compression setting is
also ignored by the TS7680. The TS7680 will attempt compression regardless of the
setting. Logical volumes defined to the TS7680 (through the IBM ProtecTIER
Manager GUI) do not take up any disk space until they are written by the host.
The TS7680 will support up to a million logical volumes.
|
|
Note: Even though 7-digit slot-values are being supported in the DISPLAY
SMS,LIBRARY command output (TOTAL SLOTS and EMPTY SLOTS), ISMF
26
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
|
|
|
|
|
and IDCAMS will still only support 6-digit slot-values and will truncate the
high order digit. The slot counts reflect the maximum number of logical
volumes that can be defined to the TS7680 (TOTAL SLOTS) and the number
of logical volumes that can still be defined (EMPTY SLOTS).
Cache Management
|
|
|
|
|
|
|
|
|
|
|
|
|
|
When the TS7680 detects that available cache space has fallen below preset
thresholds, the TS7680 sends CBR3792E (limited cache free space warning state
reached) and CBR3794A (out of cache resource critical state reached) attention
messages to the attached hosts. The CBR3792E message can be used to trigger
return to scratch processing or the copying of data to another library. If the amount
of available cache subsequently reaches the critical state, all fast ready (scratch)
mounts are failed and any specific mount operations are allowed; however, any
attempt to write to the volume will be failed. Mount operations that have been
accepted before entering this state complete and volumes currently mounted can
continue to perform host I/O operations. As appropriate, the VARY SMS,STORGRP
operator command can also be used to steer scratch allocations to another library
that is eligible for the scratch request. The DISPLAY SMS,LIBRARY command with
DETAIL, can also be used periodically to display the “CACHE PERCENTAGE
USED”.
|
|
|
|
|
|
|
|
|
|
When the host returns a volume to scratch, the TS7680 applies (by default) a nine
day grace period to the volume. The default grace period can be overridden at
install time and set to a value from 0-9 days (0 indicating no grace period). After
the grace period elapses, the data associated with the scratch volume will be
deleted from the library to free up back-end disk space, rendering the contents of
the tape volume unusable. When the TS7680 reaches the critical “Out of Cache
Resources” state (CBR3794A), it can also be configured (at install time) to
automatically delete data associated with scratch volumes that are in the “grace
period”. Volumes with the shortest time remaining in the grace period will be
deleted first. The default behavior is to honor the grace period.
|
Load Balancing
|
|
|
|
|
|
|
To balance the workload across the two enterprise tape control units, the virtual
tape devices should be divided equally across the controllers. For example, if the
size of the disk repository supports fewer than 256 devices (for example 128
devices), define 64 devices using subsystems X'01' through X'04' and 64 devices
using subsystems X'11' through X'14'. Or, if a given host only needs a subset of the
devices, spread the online devices in equal proportions across the two enterprise
control units.
|
|
|
|
|
If an imbalance across the two enterprise tape controllers is observed with one
enterprise tape controller (and its tape subsystems) getting the majority of the
mounts, consider using the new MVS Device Allocation TAPELIB_PREF
randomization option "BYDEVICES". For a discussion of the load balancing option,
refer to “Load Balancing Considerations” on page 51.

Information Center and APAR OA27786 (z/OS V1R9 and above).
Entering a Tape Cartridge into a Tape Library
To enter tape cartridges into an automated tape library dataserver, place the
cartridges into an input station of the library. The following actions occur once the
cartridges are placed in the input station:
Chapter 1. Introduction to Tape Library Management
27
v The library vision system reads the external label of each cartridge to be entered
into the library.
v The library manager notifies all connected systems that there are cartridges to be
entered into the tape library dataserver.
v The cartridge entry installation exit (CBRUXENT) is invoked to approve or deny
the request to enter the cartridges into the library.
v The volume record in the TCDB is created or updated.
Tip: To force cartridge entry processing to occur on a particular system, use the
LIBRARY DISABLE command. For more information concerning this command,
see “Disabling Installation Exit Processing” on page 110.
Tape cartridges are identified in a VTS at the library manager console through
volume serial number ranges. When a native cartridge, identified as a stacked
volume, is entered into a library, the volume is recognized as being a VTS
managed volume and is not reported to the host as a newly entered volume. Thus,
a volume record for the stacked volume is neither created or maintained in the
tape configuration database (TCDB). However, the volumes identified at the library
manager console as being logical volumes are placed in the insert category and are
processed as part of normal cartridge entry. A volume record for the logical
volume is created and maintained in the TCDB. If a logical volume fails cartridge
entry processing, the logical volume is purged from the library manager database.
For information concerning entering logical volumes into a VTS, see “Importing
Logical Volumes into a 3494 VTS System” on page 29.
Note: If you have enabled the library for outboard policy management support
and if you are defining the logical volumes to the library, the library
supports the preassignment of constructs to a volume or a range of volumes.
However, this preassignment of constructs is not recommended in the
system-managed tape environment. The host, even in coexistence, can reset
the preassigned construct names during entry processing. It is recommended
that you let the host assign the appropriate constructs during entry and job
processing.
Tape cartridges can be entered into a manual tape library through the use of the
CBRXLCS manual cartridge entry (MCE) programming interface, or through use of
the LIBRARY ENTER command. The following actions occur:
v The cartridge entry installation exit (CBRUXENT) is invoked to approve or deny
the entry request.
v The volume record in the TCDB is created or updated.
For more information on manual cartridge entry (MCE), see “Manual Cartridge
Entry (MCE)” on page 147. For more information on the LIBRARY ENTER
command, see “Entering a Tape Volume into an MTL” on page 106.
Tip: You can also use sample program CBRSPLCS to enter volumes into a manual
tape library.
Cartridge Entry Processing Without an Online Device
During cartridge entry processing, even if the library is online and operational to a
given host, at least one device needs to be online, or had been online, to that host
for the library to be able to send the cartridge entry attention interrupt to that host.
If the library is online and operational, yet there are no online devices to a given
host, that host will not receive the attention interrupt from the library unless a
device had previously been VARYed online. To get around this, ensure that at least
28
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
one device is online, or had been online, to each host or use the LIBRARY
RESET,CBRUXENT command to initiate cartridge entry processing from the host.
This is especially important if you only have one host attached to the library that
owns the volumes being entered. In general, after you have entered volumes into
the library, if you do not see the expected CBR36xxI cartridge entry messages being
issues, you can use the LIBRARY RESET,CBRUXENT command from MVS to
initiate cartridge entry processing. The LIBRARY RESET,CBRUXENT command
causes the host to ask for any volumes in the insert category.
Importing Logical Volumes into a 3494 VTS System
Note: This section discusses the import support that is available in the 3494 VTS.
For a discussion of the copy export support that is available in the TS7740
Virtualization Engine (3957-V06) and what mechanism is used to bring the
copy exported volumes back into a TS7740, refer to “Copy Export from the
TS7740 Virtualization Engine (3957-V06)” on page 39.
To introduce logical volumes with data into a VTS library or to reintroduce logical
volumes back into a VTS to reuse the volume serial numbers, the volumes must be
imported into the library. An import can be performed at the host, with a list of
logical volumes to import, or at the library manager, if a single logical volume is to
be imported. For more information concerning importing a single logical volume,
see “Importing a Single Logical Volume at the Library Manager” on page 32.
An import operation performed at the host begins with you or the tape
management system writing the list of volumes to be imported into a library on a
logical volume in the library. This logical volume then becomes the import list
volume. The input list volume indicates:
Import all logical volumes
The list of volumes written on file sequence 1 is a list of stacked volumes
to be imported into the VTS. All logical volumes residing on the stacked
volumes specified are imported.
Import specific logical volumes
In this case, the list of volumes is a list of stacked and logical volume
pairs; each stacked volume is followed by the logical volume to import.
With IMPORT LIST format 01, import option SCRATCH or INITIALIZE can be
specified along with the volume serial numbers of the stacked and logical volume
pairs. If this import option is omitted (blank), the data contents of the logical
volume are copied into the VTS system and a data fragment file entry and the
library manager record are created. If the option specified indicates “SCRATCH”,
only the data fragment file entry and the library manager record are created (data
contents not copied). If the option specified indicates “INITIALIZE”, only a library
manager record for the volume is created. If a logical volume serial number is not
included with the stacked volume serial number, the import option specified
applies to all logical volumes on the stacked volume. If you are importing into a
library that supports outboard policy management, any constructs that are
associated with the volume at the time of the export are assigned to the volume on
the import. IMPORT LIST format 02 can then be used to override these construct
names.
With IMPORT LIST format 02, you can also specify additional options to initially
set or override the policy management constructs that are associated with a
volume. You can set these options on a global or a logical volume basis. Also on a
Chapter 1. Introduction to Tape Library Management
29
global basis, the import list specification can indicate how the library manages
policy names that have not been predefined (FAILIMPORT, CREATENAME, or
USEDEFAULT).
File sequence two is written and later updated by the library manager to record
the import status of each requested logical volume. All files must be written in the
library specified format. see IBM TotalStorage Enterprise Automated Tape Library
(3494) Operator’s Guide for details regarding the library specified format. See
“SAMPLIB Member CBRSPSIM” on page 307, “SAMPLIB Member CBRSPPIM” on
page 310, and “SAMPLIB Member CBRSPPIP” on page 313 for sample JCL that
can be used to write the two required files on the import list volume.
The required stacked volumes containing logical volumes to be imported must be
entered into the library before initiating the import operation at the library. If the
import operation is initiated before the volumes have been entered and placed in
the import category, the import operation immediately fails.
Once the import list volume is written and the stacked volumes are entered into
the library, the host needs to notify the library of the logical volume being used for
the import operation and to initiate the import operation at the library. The
CBRXLCS external services programming interface FUNC=IMPORT or the
LIBRARY IMPORT command can be used to initiate the import operation and to
identify the import list volume. See “Import Logical Volumes (IMPORT)” on page
148 and “Importing Logical Volumes into a VTS” on page 175 for more
information. Only one import operation can be queued or in progress at a time in
a physical library. This is a different restriction than for export processing which
allows one export operation at a time in each VTS system. Also, if an export
operation is already queued or in process, an import operation initiated to the
same VTS system as the export operation fails. However, an import operation
initiated to a different VTS system is allowed.
When all of the requested logical volumes on a stacked volume have been
imported, the library manager places the logical volumes in the insert category to
be processed as part of normal cartridge entry processing. There are additional
flags that are passed to the cartridge entry installation exit (CBRUXENT) to
indicate that the volume is a logical volume and that it has been imported. The
logical volume flag is also set for non-imported logical volumes entered into a
VTS. This provides a mechanism for the tape management system to track logical
volumes.
For the import operation to continue with minimal host delays, it is important for
a host that owns the TCDB records for the logical volumes being imported to have
the OAM address space available to process the volumes in the insert category.
This enables the import category to be processed without delays and allows the
library to continue with the next stacked volume.
Note: If an import operation is initiated and no host processes the logical volumes
added to the insert category within 60 minutes, the VTS terminates the
import operation. This termination is equivalent to a cancel initiated by an
operator at the library manager console. See “Canceling an Import
Operation” on page 31 for more information.
All attached hosts are notified once the import operation is complete. This enables
the import completion status to be reported independently of the status of the host
that initiated the import operation. If the attached host has the import list volume
30
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
in its TCDB, messages are issued with the completion results of the import
operation. See “Import Status Messages” for more information.
To release the import stacked volumes from the library, the operator can selectively
eject the volume or volumes from the library at the library manager. Another
operator option is to alter the volume from the import category to the insert
category which would allow the stacked volume to be entered into a VTS or a
non-VTS library for reuse as a scratch stacked volume or as a physical scratch
volume. Before reusing an import stacked volume, make sure that all the logical
volumes on the stacked volume either have been successfully imported, or that the
data on the logical volumes is no longer needed.
If using DFSMSrmm as your tape management system, use the SEARCHVOLUME
subcommand with CONTAINER(volser) to verify that no logical volumes are still
associated with the stacked volume. This verification should indicate that all
logical volumes have been imported. To reuse the volume as a scratch stacked
volume, enter the volume into a VTS library. To reuse the stacked volume as a
scratch physical volume, enter the volume into a non-VTS library. The new
physical volume will be automatically added to the DFSMSrmm control data set if
DFSMSrmm is used. For more information regarding DFSMSrmm commands, see
z/OS DFSMSrmm Managing and Using Removable Media.
Rule: When a logical volume is successfully imported, the original exported copy
of the logical volume is not altered. To avoid losing changes made to the imported
copy, do not import this level of data again.
Canceling an Import Operation
If needed, the LIBRARY IMPORT,volser,CANCEL command or the CBRXLCS
external services programming interface FUNC=IMPORT with the cancel option
can be used to cancel an executing import operation to expedite other work or to
quiesce library activity in preparation for maintenance. A cancel from the host is
normally effective immediately, except for the period of time when host insert
processing is occurring for logical volumes that are being imported from a stacked
volume. In this case, the host cancel takes effect after host insert processing is
completed. The host cancellation method is the preferred method for canceling an
import operation. However, in addition to the host cancellation methods, an import
operation can also be explicitly canceled at the library manager, if there is no host
available to cancel the import operation. Differences in the cancel methods will
occur during host insert processing. If the explicit cancel occurs during host insert
processing, the import operation terminates and logical volumes that are still
assigned to the insert category are left in the insert category to be processed by the
host when it is available.
The status of all logical volumes requested for import is found in the status file of
the import list volume after the import operation completion. Exported stacked
volumes that were provided for import and were completed before the cancel are
not affected by the cancel.
Import Status Messages
As the library is processing an import operation, status messages are reported to
all attached hosts. This results in OAM issuing message CBR3750I. Status messages
are issued at the following key processing points:
v When import processing begins for a stacked volume
v When the library completes importing the requested logical volumes on a
stacked volume (that is, the volumes are in the insert category to be processed
by the host)
Chapter 1. Introduction to Tape Library Management
31
v When the import processing is complete for a stacked volume (that is, all of the
requested logical volumes on the stacked volume have been processed by OAM)
v When processing completes for the import operation
The library may also issue message CBR3750I if an error occurs during the import
operation that temporarily or permanently stops the operation.
Importing a Single Logical Volume at the Library Manager
There may be instances in which an exported logical volume is needed during job
processing and the logical volume has not previously been imported. To expedite
this process, the library allows an operator to initiate a single volume import
operation at the library manager. The operator enters the stacked volume
containing the logical volume to import and indicates which logical volume is
being imported. This eliminates the need for the host to write the logical list
volume discussed in “Importing Logical Volumes into a 3494 VTS System” on page
29.
To further assist in this process, when a logical volume is exported from the
library, the volume record in the TCDB is updated with a shelf location of
STACKED=volser (if the TCDB record is retained and the shelf location is blank).
The volume not in library installation exit sample program, CBRSPUXV, also
recognizes a shelf location of STACKED=volser and displays the stacked volume.
This allows the operator to identify the specific stacked volume on which the
requested logical volume resides. If an installation is not using this default support,
nor DFSMSrmm, custom modifications to the volume not in library installation exit
will need to be made.
The sample volume not in library exit supplied by DFSMSrmm also takes into
account whether an exported logical volume is being requested and will display
the stacked volume on which the logical volume resides.
As with a host initiated import operation, when the single volume import
operation is complete, all hosts attached to the VTS system that performed the
operation will be notified of this completion. Only one import operation, host or
library initiated, is allowed per physical library.
Checking the Volume Serial Number for Uniqueness
When entering tape cartridges into a tape library, OAM checks each volume serial
number in the insert category for uniqueness (see “Volume Serial Number
Restrictions” on page 35). If there is already an SMS-managed DASD or optical
volume with the same volume serial number as the tape volume being entered, the
cartridge entry is rejected. Also, if the media type of the volume being entered
does not match the media type of the volume in the TCDB, cartridge entry is
rejected. For cartridge entry processing into a manual tape library, only DASD
volumes are checked for uniqueness.
If OAM determines that the volume serial number is unique, it obtains the tape
volume record from the TCDB. Depending on whether or not a record is found,
several different actions can occur:
v Tape volume record is not present (for a newly entered cartridge, normal
cartridge entry occurs).
v Tape volume record indicates the volume is in another library (In an automated
tape library environment, a check is made to determine if the volume still
32
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
resides in the other library. If the volume does not reside in that library, entry
processing continues. In a manual tape library environment, since a check cannot
be made, entry is denied).
v Tape volume record indicates volume is in this library (In an automated tape
library environment, entry processing continues. In a manual tape library
environment, since the possibility of a duplicate exists, entry is denied.).
v Tape volume record indicates volume shelf-resident (normal cartridge reentry).
Before the volume record is created or updated, the cartridge entry installation exit
(CBRUXENT) is called to set or verify values for many of the record fields. See
“Cartridge Entry Installation Exit (CBRUXENT)” on page 221 for a list of fields.
Using Global Resource Serialization with Cartridge Entry
Processing
Cartridge entry processing is usually serialized; that is, one system performs
cartridge entry for the entire SMS complex. This is accomplished by using global
resource serialization (GRS) with a SYSTEMS level enqueue.
The resource names are as follows:
QNAME-SYSZCBR
RNAME-CARTRIDGE_ENTRY_libname
If the library is a PtP VTS, the libname represents the composite library.
Note: OAM already performs a SYSTEMS level enqueue for global resource
serialization. If you are using IBM global resource serialization ring or star
support, you do not need to include the QNAME or RNAME in the
SYSTEM inclusion RNL. The QNAME and RNAME are provided for
documentation purposes. If a GRS-equivalent product is being used, refer to
that product documentation to ensure that the SYSTEMS level enqueue is
honored and for any setup that might be needed to propagate the enqueue
across your systems.
It is possible to perform cartridge entry processing without global resource
serialization. The consequences of unserialized processing are as follows:
1. Cartridge entry occurs concurrently in all processors. Each processor handles a
subset of the entered volumes.
2. Some additional processing overhead takes place, due to concurrent processing
of the same list of volumes.
3. The cartridge entry installation exit is entered once for each volume on each
processor. The installation must account for this possibility when writing the
exit.
Recommendation: Use global resource serialization.
Related reading: For more information on using GRS, see z/OS MVS Planning:
Global Resource Serialization.
Using Global Resource Serialization in a Manual Tape Library
To serialize tape configuration database (TCDB) updates during cartridge entry,
eject, and change use attribute processing, a systems level enqueue, at the volume
serial number level, is performed using global resource serialization.
Chapter 1. Introduction to Tape Library Management
33
The resource names are as follows:
QNAME-SYSZCBR
RNAME-MTL_VOLSER_volsername
Note: OAM already performs a SYSTEMS level enqueue for global resource
serialization. If you are using IBM's global resource serialization ring or star
support, you do not need to include the QNAME or RNAME in the
SYSTEM inclusion RNL. The QNAME and RNAME are provided for
documentation purposes. If a GRS-equivalent product is being used, refer to
that product documentation to ensure that the SYSTEMS level enqueue is
honored and for any setup that might be needed to propagate the enqueue
across your systems.
Recommendation: Use global resource serialization. Without this serialization,
simultaneous processing of the same volser may result in a double increment or
decrement of the appropriate scratch count.
Tape Volume Requirements
The ATLDS and the MTL support a multitude of IBM tape cartridge types,
depending on the tape devices and media types supported in the library. Each tape
volume is identified by a unique volume serial number with the following
requirements being enforced:
v All physical volumes residing in an ATLDS must have a supported external
barcode label readable by the automated tape library dataserver vision system
unless the unlabeled tape facility at the library manager is being used.
v All volumes residing in a MTL should also have a supported machine readable
external label to be compatible with the ATLDS.
v All private volumes must have either an internal IBM standard tape label or an
International Organization for Standardization American National Standards
Institute (ISO/ANSI) label, unless bypass label processing (BLP) or nonlabeled
tape (NL) is specified.
v All private volumes must have identical internal and external volume serial
numbers, unless BLP or NL is specified. The internal volume serial number is
recorded in the tape volume label (VOL1 label).
v BLP or NL may be requested for input processing on specific volume serial
references. It may also be requested for output processing on specific or
nonspecific references.
v All volume serial numbers in the same SMS complex must be unique across
tape, DASD, and optical environments.
v A scratch volume cannot be requested using a specific volume serial number.
v All volumes of a multivolume data set should reside in the same library, or all
should reside outside a library; however, if they do not, the installation will be
given the chance to enter the volumes through the volume not in library
installation exit (CBRUXVNL).
v All volumes of a multivolume data set must belong to the same tape storage
group.
v All volumes of a multivolume data set must be recorded using the same tape
recording technology.
v Volumes of a multivolume data set may be an intermix of media types
supporting the same recording technology.
v Volumes of a multivolume data set must be recorded either on all rewritable
media or on all WORM media and cannot be intermixed.
34
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Accessing the Tape Volumes
Because tape volumes can reside either inside libraries or on shelves outside the
library, physical procedures for accessing volumes vary according to their location:
v When a library-resident volume is requested, the system mounts it on a tape
drive in the tape library containing the volume.
v When a shelf-resident volume is requested, the installation is given the
opportunity to enter the volume into a tape library by using the volume not in
library installation exit. If the volume is not entered into the library, the system
requests the volume be mounted on a nonlibrary device (stand-alone tape drive).
Note: Shelf storage may be local to the computer facility and, therefore,
accessible to the operator, or it may be located at another location.
Volume Serial Number Restrictions
When a physical tape volume is entered into an ATLDS or MTL, the cartridge
must have an external label (readable by machine, human, or both). If the volume
is assigned the private use attribute on entry into the tape library, a magnetically
recorded volume serial number on the tape volume label must be present and
match the volume serial number on the external label. This label is not checked on
entry into the tape library, so if there is an error, it is not detected until the volume
has been mounted and the label has been read.
If the volume is assigned the scratch use attribute and no volume serial number
exists for it, a new volume label with a matching volume serial number is written
whenever the data set is opened for output on the tape. For a scratch volume with
an existing volume serial number that does not match the volume serial number
on the external label, the internal label is rewritten to match the external label.
Recommendation: In the case of an MTL scratch volume, since the label process is
not automated, use the IEHINITT utility (or RMM equivalent EDGINERS) to
pre-label the scratch cartridge; otherwise, the operator may be prompted for the
volume serial number when the volume is first mounted for output.
Ejecting a Tape Cartridge from a Tape Library
Ejecting a cartridge from a tape library breaks the connection between the cartridge
and the library in which it resided. Cartridges may need to be moved to a different
location and must therefore be ejected from the library in which they currently
reside so they may be put into a library at the new location. Once the cartridges
are ejected from the library in which they reside, they are no longer associated
with that library and are not eligible to be mounted in the library without going
through the cartridge entry process.
In the automated tape library environment, there is currently a limit on the
number of eject requests that device services can have queued across all libraries
from a single system. This queue limit is currently set at 1600. For this limit to be
as transparent as possible, OAM will not send more than 100 eject requests to a
single library from a single system. If OAM receives more than 100 eject requests
for a given library, it will wait until an eject request completes before sending
another request to that library. However, if the OAM address space is stopped or
restarted with an SCDS activation, rather than purging the remaining eject
requests, OAM will try and send down as many of the remaining eject requests as
it can before reaching the device services queue limit of 1600. Additionally, there is
a Peer-to-Peer VTS system limitation. This library will only accept up to 1000 eject
requests across all connected systems.
Chapter 1. Introduction to Tape Library Management
35
Recommendation: Given these limitations (and potential storage constraints when
processing thousands of outstanding eject requests), limit the number of
outstanding eject requests at any given time to no more than a couple thousand
per system. Then, as the outstanding eject requests complete, more can be initiated.
Cartridges can be ejected from a tape library in several ways, as shown in Table 2:
Table 2. Methods for Ejecting Cartridges from a Tape Library

panel.
“Ejecting a Volume from a
Tape Library” on page 367
Application program

“Ejecting a Tape Cartridge”
on page 163
Before a cartridge can be ejected from a tape library, the cartridge eject installation
exit (CBRUXEJC) is invoked to approve or deny the eject request. See “Cartridge
Eject Installation Exit (CBRUXEJC)” on page 232 for more information.
Rule: OAM does not support the manual removal of volumes from a 3494 tape
library for the purpose of ejecting them. The volumes which are manually ejected
from a library are still library-resident in the TCDB, causing an
out-of-synchronization condition with the library manager database. Volumes must
be ejected following the methods outlined in Table 2.
When OAM ejects a tape volume residing in a manual tape library, no automated
movement of the cartridge takes place. It is up to the operator to physically
remove the tape cartridge from the storage racks associated with the manual tape
library.
After the eject request completes, OAM notifies the invoker of the eject request of
its success or failure and the volume record in the TCDB is updated or deleted.
For information concerning exporting or removing a logical tape volume from a
VTS, see “Exporting Logical Volumes from a 3494 VTS System” on page 37 and
“Ejecting a Logical Volume from a VTS.”
Ejecting a Logical Volume from a VTS
If a logical volume is in a fast ready category at the VTS, it can be ejected (purged)
from the library using the methods described in Table 2. An export operation for
the purpose of deleting a logical scratch volume is not required. If a logical volume
is in the insert category, it can also be ejected (purged) using the same methods
after a TCDB record is manually created or updated indicating that the volume
resides in the library. For information concerning an export operation, see
“Exporting Logical Volumes from a 3494 VTS System” on page 37.

z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Exporting Logical Volumes from a 3494 VTS System
Note: This section discusses the export support that is available in the 3494 VTS.
For a discussion of the copy export support that is available in the TS7740
Virtualization Engine (3957-V06), refer to “Copy Export from the TS7740
Virtualization Engine (3957-V06)” on page 39.
To remove a set of logical volumes from a VTS, the operator or the tape
management system should first run a vaulting-type operation at the host to
determine the list of logical volumes to be exported. This list is then written in
volume serial number and destination pairs as the first file on an available logical
volume. This volume then becomes the export list volume. This export list volume
must reside in the library where the volumes to be exported reside and it must be
written in a library specified format. Two more files are also written on this export
list volume. File sequence two is a file reserved for future use. File sequence three
is written and later updated by the VTS to record the export status of each logical
volume listed in the export list. All three files must be written in the library
specified format.
See IBM TotalStorage Enterprise Automated Tape Library (3494) Operator’s Guide for
details regarding the library specified format. See “SAMPLIB Member CBRSPSXP”
on page 317 and “SAMPLIB Member CBRSPPXP” on page 320 for sample JCL that
can be used to write the three required files on the export list volume. The
DFSMSrmm SEARCHVOLUME command with the CLIST option can be used to
create this export list. For more information on this command, see z/OS
DFSMSrmm Managing and Using Removable Media.
Once the export list volume is written, the LIBRARY EXPORT command or the
CBRXLCS external programming interface FUNC=EXPORT can be used to identify
the export list volume and to initiate the export operation at the library. For more
information, see “Export Logical Volumes (EXPORT)” on page 148 and “Exporting
Logical Volumes from a VTS” on page 173. Only one export operation can be
queued or in progress at a time in each VTS system. Also, if an import is currently
queued or in progress, an export operation cannot be initiated to the same VTS
system.
The library then mounts the export list volume and determines the list of volumes
to export and either the destination or destinations for the logical volumes. Logical
volumes with the same destination will be grouped together on the same stacked
media. This lets a single export operation cover multiple destination sites. The
library then begins writing the export logicals on stacked volumes. If the VTS has
outboard policy management support, the volume's policy names are included on
the stacked volume. On the third file of the export list volume, the library records
the status of each logical volume being exported; this can be referred to as the
export status file. If a volume cannot be exported because it is currently in use or
does not exist in the library, the export status file indicates the error that occurred,
as well as reflects the successful export of each logical volume. Each exported
stacked volume contains a volume map identifying the contents of the stacked
volume, logical volume data fragment files for each logical volume successfully
copied, and the logical volumes themselves. A single export operation may result
in many stacked volumes being exported with multiple volumes per destination.
As the library manager finishes with a stacked volume, the logical volumes are
assigned to the exported category. The volumes in this category are then processed
by OAM. Volume export processing is similar to eject processing; however, in
addition, the cartridge eject installation exit (CBRUXEJC) is passed the container
Chapter 1. Introduction to Tape Library Management
37
volume serial number of the stacked cartridge on which the logical volume resides.
This is information that the tape management system will want to record. The tape
management system’s acceptance of the eject is implicit (there is no opportunity to
fail the eject). However, in an environment where a common TCDB is shared by
more than one tape management system and each tape management system has its
own database, the tape management system can return UXJIGNOR, Return Code
12, to allow another tape management system who “owns” the exported volume to
process. If UXJIGNOR is returned from the CBRUXEJC installation exit, the logical
volume remains in the exported category; otherwise, each logical volume is then
purged from the library manager inventory and the host TCDB volume record is
kept or purged, depending on the disposition specified by the installation exit or
defaults set for the library when it was defined using ISMF.
Once all logical volumes residing on a stacked cartridge have been successfully
purged from the library manager inventory, the export operation continues at the
library, filling another stacked volume for the destination currently being
processed. The completed stacked cartridge can then be released by an operator at
the library manager either on an individual completion basis, or after a set of
volumes has been processed. For the export operation to continue with minimal
host delays, it is important for a host that owns the TCDB records for the logical
volumes being exported to have the OAM address space available to process the
volumes in the exported category. This enables the exported category to be
processed without delays and allows the library to continue with the next stacked
volume.
Attention: If an export operation is initiated and no host processes the exported
category within 60 minutes, the VTS terminates the export operation. This
termination is equivalent to a cancel initiated by an operator at the library manager
console. See “Canceling an Export Operation” for more information.
Once the export operation is complete, all hosts attached to the VTS system that
performed the operation are notified of this completion. This enables export
completion status to be reported independently of the status of the host that
initiated the export operation. If the attached host has the export list volume in its
TCDB, messages are issued with the completion results of the export operation.
Status messages are also issued at key processing points throughout the export
operation. See “Export Status Messages” on page 39 for more information.
Canceling an Export Operation
Because an extensive list of export volume candidates could take considerable time
to complete, it might be necessary to cancel an export operation to expedite other
processing or to quiesce the library activity in preparation for maintenance. The
LIBRARY EXPORT,volser,CANCEL command or the CBRXLCS external services
programming interface FUNC=EXPORT with the cancel option can be used for this
purpose. A cancel from the host is normally effective immediately, except for the
period of time when host purge processing is occurring for logical volumes being
exported to the exported stacked volume. In this case, the host cancel takes effect
after host purge processing is completed for the exported stacked volume.
The host cancellation method is the preferred method for canceling an export
operation. However, in addition to host cancellation methods, you can also
explicitly cancel an export operation at the library manager if there is no host
available to cancel the export operation. Differences in the cancel methods will
occur during host purge processing. If the explicit cancel occurs during host purge
processing, the export operation terminates and logical volumes in the exported
category are placed in the insert category (none of these logical volumes will be
38
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
exported) and the host will perform insert processing on these logical volumes
when it is available. The exported stacked volume will go back into the pool of
usable scratch stacked volumes.
The status of all logical volumes requested for export is found in the status file of
the export list volume after the export operation completes. Exported stacked
volumes that were completed and placed in the export hold category before the
cancel are not affected by the cancel.
Export Status Messages
As the library is processing an export operation, status messages are reported to all
attached hosts. This results in OAM issuing operator message CBR3750I. Status
messages are issued at the following key processing points:
v When export processing begins for a particular destination
v When the library completes a stacked volume and the logical volumes are in the
exported category and ready for host processing
v When the library completes a stacked volume and it is ready to be released
(ejected) by an operator
v When processing completes for a particular destination
v When processing completes for the export operation
The library may also issue message CBR3750I if an error occurs during the export
operation that temporarily or permanently stops the export operation.
Copy Export from the TS7740 Virtualization Engine (3957-V06)
A copy of the data within a TS7740 Virtualization Engine (3957-V06) can be
removed from the library, both in a stand-alone and in a multi-grid configuration.
The information below discusses the copy export capability in a stand-alone and in
a multi-grid configuration.
Copy export enables a copy of the data to be used for disaster recovery purposes
while the original data remains accessible for production use. For the recovery of
the copy exported volumes, a modified disaster recovery process is used instead of
an import. The copy export support builds on the existing capability (through
advanced policy management and management class) to create a secondary copy
of a logical volume in a secondary physical pool. During a copy export operation,
all of the physical volumes with active data on them, from a specified secondary
pool, are removed from the library associated with the TS7740 performing the
export operation. Only the logical volumes that are valid on that TS7740 are
considered during the execution of the operation (if they are in the cache, but have
not yet been copied to the secondary pool, copies are performed as part of the
copy export operation). If the TS7740 is in a grid configuration, copies that have
not yet been completed to the TS7740 performing the copy export operation are
not considered during the execution of the operation. It is expected that the copy
export operation runs on a periodic basis resulting in multiple groups of physical
volumes containing the copies of the logical volumes from the TS7740. However,
the number of offsite volumes a TS7740 allows is limited to 2000. When a copy
export is initiated, the TS7740 determines the total count of physical volumes that
are currently offsite, then add to that number the number of physical volumes in
the specified pool that have active data on them and would be exported. If that
number exceeds 2000, the export fails. During the copy export operation, a copy of
the current TS7740’s database is written to the exported physical volumes. To
restore access to the data on the physical volumes that have been removed, all
exported physical volumes for a source TS7740 are placed into a library that is
Chapter 1. Introduction to Tape Library Management
39
attached to an empty TS7740. A disaster recovery procedure is then performed that
restores access using the latest copy of the database.
The physical volumes exported during a copy export operation continue to be
managed by the source TS7740 in regards to space management. As logical
volumes that are resident on the exported physical volumes are expired, rewritten
or otherwise invalidated, the amount of valid data on a physical volume decreases
until the physical volume becomes eligible for reclamation based on the criteria
provided by the customer. The exported physical volumes to be reclaimed are not
brought back to the source TS7740 for processing, instead, a new secondary copy
of the remaining valid logical volumes are made using the primary logical volume
copy as a source. The next time the copy export operation is performed, the
physical volumes with the new copies are also exported. The physical volumes that
were reclaimed (that are offsite) are no longer considered to have valid data and
can be returned to the source TS7740 to be used as new scratch volumes.
Before initiating a copy export operation using the existing LIBRARY EXPORT
command, the export list volume must first be created on the TS7740 that is to
perform the export operation (using export list format 03). When creating the
export list volume, since a multi-cluster grid configuration can have drives online
in more than one TS7740, management class can be used to direct in which TS7740
the export list volume is created. For copy export, the export list volume cannot be
valid on more than one TS7740 in a grid configuration, it must only be valid on
the TS7740 that is to perform the copy export operation, otherwise the request fails.
Then when the LIBRARY EXPORT command is issued, the library directs the
export operation to the TS7740 that has a valid copy of the export list volume
(again, only one TS7740 can have a valid copy of the export list volume for the
export operation to proceed). The export list volume contains instructions
regarding the execution of the operation (the number of the secondary pool to
export) as well as a reserved file that the TS7740 uses to provide completion status
and export operation information. As part of the execution of the copy export
operation, the TS7740 creates response records in the reserved file that lists the
logical volumes exported and the physical volume that they reside on. This
information may be used by the users as a record for what data is offsite. The
TS7740 also writes records in the reserved file on the export list volume for any
offsite physical volumes that have been reclaimed and no longer contain any active
data.
The copy export operation can also be cancelled using the existing LIBRARY
EXPORT command with the CANCEL option or it can be cancelled at the library.
For a copy export, processing for the current physical volume completes. Status
files are written for all logical and physical volumes which completed export
processing.
In addition to providing a list of the offsite physical volumes that are empty in the
export list volume status file, the Bulk Volume Information Retrieval (BVIR)
function can also be used to obtain a current list of exported physical volumes for
a secondary pool. For each exported physical volume, information is provided
regarding the amount of active data that each contains.
Because the primary copy of the logical volumes being exported are not removed
from the TS7740, no notification of their change in state is performed at the host
(the logical volumes are not placed in the exported category, nor is the host
notified on which physical volume the exported logical volume resides). Instead,
the database entries at the library for the physical volumes are updated to indicate
that they have been exported and the hosts are notified that export processing has
40
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
been completed. In addition to the export completion message which results in the
generation of a console message, status messages are also generated during the
export operation and displayed at the console using the existing CBR3750I
message. When the export operation completes, the user can eject the exported
copy physical volumes from the library and move them to an offsite location.
For additional details on the copy export support and the BVIR function, refer to
IBM Redbook, IBM System Storage Virtualization Engine TS7700: Tape Virtualization
for System z Servers, and the following IBM Whitepapers: IBM Virtualization Engine
TS7700 Series Bulk Volume Information Retrieval User's Guide and IBM Virtualization
Engine TS7700 Series Copy Export User's Guide.
Host Implications
A copy export operation is initiated using the existing LIBRARY EXPORT
command. However, unlike the export support that is available in the 3494 VTS,
when the logical volumes are exported from the , a copy of the logical volume
remains in the library. So from a host database perspective the logical volumes are
still library resident. There is no automatic notification to the host (or to the tape
management system) that a copy of the logical volume also exists outside the
library. When logical volumes are exported from the 3494 VTS, the volumes are
placed in an exported category and the host is notified. As part of this notification,
the host processes each volume in the exported category. This results in the host
and the tape management system updating their database to indicate that the
volume now resides outside the library. The capability also exists for this support
to track on which physical volume an exported logical volume now resides.
Because there is no host notification with a copy export, it is up to the user to
manage and track the exported physical volumes. One mechanism may be to use
the existing SHELF LOCATION field in the tape configuration database (TCDB).
This is a 32-byte free form field which is available for the users. As with the 3494
VTS support, a customer can use the SHELF LOCATION field to track on which
physical volume the logical volume resides (using IDCAMS ALTER
VOLUMEENTRY). For example, COPY EXPORT STACKED=xxxxxx could be placed in
this field to differentiate from STACKED=xxxxxx which is used with the 3494 VTS
support. For users that use DFSMSrmm, when you have stacked volume support
enabled, DFSMSrmm automatically handles and tracks the stacked volumes
created by copy export. However, there is no way to track which logical volume
copies are on the stacked volume. You should retain the updated export list file
created by you and updated by the library, so that you have such a record. Refer to
z/OS DFSMSrmm Implementation and Customization Guide, SC26-7405 for more
information about DFSMSrmm support of copy export.
Using Global Resource Serialization with Export Processing
To prevent multiple hosts from attempting to simultaneously process logical
volumes in the export category, a SYSTEMS level enqueue, similar to cartridge
entry processing, is used. The resource names are:
QNAME—SYSZCBR
RNAME—EXPORTED_CATEGORY_libname
It is possible to perform export processing without global resource serialization.
The following are the consequences of unserialized processing:
1. Export completion processing occurs simultaneously in all processors. Each
processor handles a subset of the exported volumes.
2. Some additional processing overhead takes place, due to concurrent processing
of the same list of volumes.
Chapter 1. Introduction to Tape Library Management
41
3. The cartridge eject installation exit is entered once for each volume on each
processor. The installation must account for this possibility when writing the
exit.
Recommendation: Use global resource serialization.

Chapter 2. Planning for the Tape Library Support
In many ways, planning is the most important phase of a product’s
implementation and administration cycle. Time spent in planning is fully repaid in
time, effort, and money saved by a well-implemented installation and a smooth
transition to full system integration. This chapter identifies key areas that must be
addressed during the planning stage for tape library support, as well as installation
procedures to follow when you are ready to install OAM. Rather than repeat large
amounts of information available elsewhere, this chapter focuses specifically on
issues related to tape library dataservers and provides references to other
resources.
Analyzing Your Hardware Environment
Installing a new product is rarely an isolated event. Planners must evaluate how
the environment is affected by the new product, as well as how to customize the
new product to integrate it with the existing components. This section presents
hardware and media requirements and considerations.
Hardware
Drive types supported in a tape library:
3480
Identified in JCL statements as UNIT=3480. Only supported in the
MTL.
3490
Sometimes referred to as a base 3490. It is identified on JCL
statements as UNIT=3480X. Supported in the 3495 ATLDS and in
the MTL.
3490E
It is identified on JCL statements as UNIT=3490. Supported in the
3495 and 3494 ATLDS and in the MTL.
3590-1
It is identified on JCL statements as UNIT=3590-1. Supported in
the 3495 and 3494 ATLDS and in the MTL as a 3590 Model B Tape
Subsystem.
3590-E
It is identified on JCL statements as UNIT=3590-1 or UNIT=3490.
Supported in the 3494 ATLDS and in the MTL in 3590-1 emulation
mode as a 3590 Model E Tape Subsystem.
3590-H
It is identified on JCL statements as UNIT=3590-1 or UNIT=3490.
Supported in the 3494 ATLDS and in the MTL in 3590-1 emulation
mode as a 3590 Model H Tape Subsystem.
3592-J
It is identified on JCL statements as UNIT=3590-1 or UNIT=3490.
Supported in the 3494 or 3584 ATLDS and in the MTL in 3590-1
emulation mode as a 3592 Model J Tape Subsystem.
3592-2
It is identified on JCL statements as UNIT=3590-1. Supported in
the 3494 and 3584 ATLDS and in the MTL in 3590-1 emulation
mode as a 3592 Model E05 Tape Subsystem (not encryption
capable).
3592-2E
It is identified on JCL statements as UNIT=3590-1. Supported in
the 3494 and 3584 ATLDS and in the MTL in 3590-1 emulation
mode as a 3592 Model E05 Tape Subsystem with encryption

capability (capable from a host perspective implies that the
encryption feature in the drive is enabled).
It is identified on JCL statements as UNIT=3590-1. Supported in
the 3494 and 3584 ATLDS and in the MTL in 3590-1 emulation
mode as a 3592 Model E06 Tape Subsystem with encryption
capability (capable from a host perspective implies that the
encryption feature in the drive is enabled). Unlike the 3592 Model
E05, a non-encryption capable version of the 3592 Model E06
(3592-3) is not supported under System z with control unit
attached devices.
3592-3E
Notes:
1. The 3495 ATLDS can be configured with 3490, 3490E, and 3590 Model B tape
subsystems.
2. The 3494 ATLDS can be configured with 3490E, 3590 Model B, 3590 Model E,
3590 Model H, 3592 Model J, 3592 Model E05, and 3592 Model E06 tape
subsystems.
3. The 3584 ATLDS can be configured with 3592 Model J, 3592 Model E05, and
3592 Model E06 tape subsystems.
4. The MTL can be configured with 3480, 3490, 3490E, 3590 Model B, 3590 Model
E, 3590 Model H, 3592 Model J, 3592 Model E05, and 3592 Model E06 tape
subsystems.
Note: Due to the compaction incompatibility between the 3480 and the base
3490 (3480X), both of these device types are not allowed in the same
manual tape library.
5. Though a mix of tape subsystem is supported within a library (ATLDS or
MTL), all drives under the same control unit must have the same capabilities.
This ensures that all of the devices under the same control unit are capable of
handling the same allocation request.
Table 3 describes hardware configurations that can be used separately or in specific
combinations to create or modify your tape storage environment. The notes that
correspond to the reference numbers in the table are listed at the end of the table.

9. The library models indicated can be configured with any combination of correlating tape subsystem devices. These
configurations may vary in the number of drives, slots, and media type supported in the libraries.
WORM Considerations
The write-once, read-many (WORM) function of tape data storage is accomplished
on the 3592 models through a combination of microcode controls in the drive and
special WORM tape cartridges. All 3592 drives with the appropriate version of
microcode installed are capable of reading and writing MEDIA6 and MEDIA8
WORM cartridges. The MEDIA10 WORM tape is only applicable with the 3592-2,
3592-2E, and 3592-3E drive models.
When the drive senses that a cartridge is a WORM cartridge, the microcode
prohibits alteration of user data already written on the tape by means of an
overwrite-protection pointer stored in the cartridge memory (CM). Statistical
Analysis and Reporting System (SARS) data can be written and updated on
WORM tapes because the SARS data is not in the user area of the tape. Each
WORM cartridge is identified using a world-wide unique cartridge identifier
(WWCID), which is permanent and locked, providing another level of security for
Chapter 2. Planning for the Tape Library Support
47
data that must be maintained. This permanent locked information is stored in both
the cartridge CM and on the tape itself, and can also be associated with the unique
barcode VOLSER.
While the overwriting of data is not allowed on a WORM cartridge, appending of
data is allowed under certain conditions. For example, an additional file can be
appended following the last file on a tape. Records can also be appended to the
last file written on the tape.
In the system-managed tape library environment (ATLDS or MTL), WORM media
is not mounted by default to satisfy a scratch mount request. WORM scratch
volumes must be explicitly requested through data class by the specification of
MEDIA6, MEDIA8 or MEDIA10. In the MTL environment, WORM scratch mounts
can be managed through the tape management system pooling support instead of
by data class. The DEVSUPxx PARMLIB member keyword,
MTL_NO_DC_WORM_OK, allows a WORM scratch volume to be used even if it is
not explicitly requested through data class.
Also see “Logical WORM Considerations” on page 25.

Manual Tape Library Hardware Considerations
Operation of this support outside of the true stand-alone environment is not
intended. To determine the feasibility of this support within a non-IBM robotic
tape library, contact the manufacturer of the robotic tape library. Also, if a vendor's
tape device, emulating a 3490E or 3590 native device, is defined to the library, the
manual tape library support will treat this device as a real 3490E or as a real 3590
Model B. When entered into the library, the media must be defined as its emulated
media. It is then your installation's responsibility to manage media or device
incompatibilities. This can be managed by keeping incompatible devices with the
same emulated or real device type in separate libraries.
In addition, the manual tape library support can also be used to help manage the
IBM System Storage TS3400 Tape Library (3577 Model L5U). Even though the 3592
Model E05 and E06 drives in the TS3400 tape library are in an automated tape
library, unlike the 3494 or 3584 tape libraries, the drives in the TS3400 report to the
host as if they were stand-alone drives with cartridge loaders. As such, the normal
system-managed tape library support that is available with the 3494 or 3584 tape
libraries is not applicable to the TS3400. Instead, the drives in the TS3400 must be
defined to the host as stand-alone tape drives. For information on the TS3400, refer
to IBM System Storage TS3400 Tape Library Planning and Operator Guide and the IBM
Whitepaper: Overview of IBM TS1120 Tape Controller Support for TS3400 Tape Library.
Managing Multiple Media Formats
Your planning strategy must include consideration of multiple media formats and
a choice of cartridge system tapes. The TCDB provides the tape device selection
information (TDSI) that determines the data class attributes assigned to a volume.
Depending on the IBM subsystems, available features, and interchange
requirements between stand-alone and library-resident tape drives, you should
include the following multimedia considerations:
1. Should data compaction be used?
2. Does the tape subsystem write in 18-track, 36-track, 128-track, 256-track,
384-track, EFMT1, EFMT2, , EEFMT2, EFMT3 or EEFMT3 format?
3. Does the tape subsystem use IBM Cartridge System Tape, IBM Enhanced
Capacity Cartridge System Tape, IBM High Performance Cartridge Tape, IBM

Extended High Performance Cartridge Tape, IBM Enterprise Tape Cartridge,
IBM Enterprise WORM Tape Cartridge, IBM Enterprise Economy Tape
Cartridge, IBM Enterprise Economy WORM Tape Cartridge, IBM Enterprise
Extended Tape Cartridge, or IBM Enterprise Extended WORM Tape Cartridge?
Compaction Considerations: Compacting data may increase effective storage
capacity. The 3490E subsystem uses the improved data recording capability (IDRC)
as the default mode. IDRC is a standard feature on the 3490 subsystems. The 3590
and 3592 subsystems use an improved compaction algorithm to increase effective
cartridge data capacity.
Recording Technology Considerations: The 3490 subsystem writes data in the
18-track format. Data written in the 18-track format can be retrieved or read by the
3490E. All 3490E subsystems write data in the 36-track format, which doubles the
storage capacity of a tape cartridge.
The 3590 Model B tape drives write data in the 128-track format, the 3590 Model E
tape systems write data in the 256-track format, and the 3590 Model H tape
systems write data in the 384-track format. Data that is written on a 3590 Model B
tape system can also be read on 3590 Model E or Model H tape systems. Data that
is written on a 3590 Model E can also be read on a 3590 Model H.
The 3592 Model J tape drives read and write only in EFMT1 format.
The 3592 Model E05 tape drives read and write in EFMT1 and EFMT2 formats.
The encryption-capable 3592 Model E05 tape drives read and write in EFMT1,
EFMT2, and EEFMT2 formats.
The 3592 Model E06 tape drives read EFMT1, EFMT2, EEFMT2, EFMT3, and
EEFMT3 and write EFMT2, EEFMT2, EFMT3, and EEFMT3 formats.
Tape Capacity Considerations: It is important to keep in mind the capacities of the
tape cartridges you are using within the tape library to allow the most efficient use
of the storage space available. Table 3 on page 44 depicts the capacity differences
between the tape cartridge types.

Tape Device Selection Information
The device selection attributes of a tape volume are recorded in the TDSI fields of
the tape volume record. The TDSI fields are set when a tape cartridge is entered
into a library. Your installation should provide a cartridge entry installation exit to
assist in the process of setting the TDSI fields. See “Cartridge Entry Installation
Exit (CBRUXENT)” on page 221 for more information concerning this cartridge
entry installation exit. See “TDSI Coexistence Considerations” on page 70 for more
information on TDSI. The following tape device selection information is assigned
to the tape volume:

v Recording technique-specified as UNKNOWN, 18TRACK, 36TRACK,
128TRACK, 256TRACK, 384TRACK, EFMT1, EFMT2, EEFMT2, EFMT3, or
EEFMT3.

MEDIA5, MEDIA6, MEDIA7, MEDIA8, MEDIA9, or MEDIA10.
v Compaction-specified as UNKNOWN, NONE, or COMPACTED.
v Special attribute-can be set to NONE or READCOMPATIBLE.
3490 read-compatibility processing allows a MEDIA1 cartridge written on a base
3490 device using 18-track recording technique to be mounted and read on a 3490E
device. Data originally written to a volume using a base 3490 can be overwritten
using a 3490E device as long as the recording starts at the load point of the
volume. However, using a 3490E device to write additional data starting in the
middle of a volume originally written by a base 3490 is not permitted, since this
intermixes the 18-track and 36-track recording techniques on the same volume.
In a nonlibrary environment, the allocation process provides two system-defined
esoteric unit names—SYS3480R and SYS348XR—that allow the installation to
specify that the volume is used for read-only purposes so that 3490E drives
become eligible for allocation.
3590 Model E read-compatibility processing allows a MEDIA3 or MEDIA4
cartridge written on a 3590 Model B using the 128-track recording technique to be
mounted and read on a 3590 Model E. Data originally written to a volume using a
3590 Model B can be overwritten using a 3590 Model E as long as the recording
starts at the load point of the volume. However, using the 3590 Model E to write
additional data starting in the middle of a volume originally written by a 3590
Model B is not permitted, because this intermixes the 128-track and 256-track
recording techniques on the same volume.
3590 Model H read-compatibility processing allows a MEDIA3 or MEDIA4
cartridge written on a 3590 Model B tape drive using the 128-track recording
technique or a cartridge written on a 3590 Model E tape drive using the 256-track
recording technique to be mounted and read on a 3590 Model H tape drive. Data
that was originally written to a volume using a 3590 Model B or Model E tape
drive can be overwritten using a 3590 Model H tape drive as long as the recording
starts at the load point of the volume. However, using the 3590 Model H tape
drive to write additional data starting in the middle of a volume originally written
by a 3590 Model B or Model E tape drive is not permitted, because this intermixes
the recording techniques on the same volume.
3592 read-compatibility processing for the 3592 Model E05 and E06. Because the
3592 Model E05 is downward read and write compatible with the EFMT1 format,
explicit specification of the read-compatible special attribute indicator (TDSSPEC)
or usage of the LABEL=(,,,IN) on the DD statement of JCL, is not required for an
EFMT1 formated cartridge to be read on a 3592 Model E05. However, since the
3592 Model E06 is only downward read compatible with the EFMT1 format,
explicit specification of the read-compatible special attribute indicator (TDSSPEC)
or usage of the LABEL=(,,,IN) on the DD statement of JCL is required for the 3592
Model E06 to be considered eligible for an EFMT1 read request. Furthermore, since
the 3592 Model E06 can read and write the EFMT2 and EEFMT2 recording formats,
no read-compatible considerations are needed for the EFMT2 or EEFMT2 formats.
In a nonlibrary environment, there are no equivalent 3590 system-defined esoteric
unit names.
50
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
For a request for an SMS-managed volume, the JCL UNIT specification is ignored,
so read-compatibility must be managed in a different manner. There is a special
attribute field included in the TDSI that can be set to read-compatible, allowing
3490E drives to become eligible to manage requests for 18-track recorded volumes,
3590 Model E drives to become eligible to manage 128-track recorded volumes,
and 3590 Model H drives to become eligible to manage 128-track and 256-track
recorded volumes. Your installation is responsible to set the read-compatible
special attribute in either of the following manners:
v Using the cartridge entry installation exit (CBRUXENT).
v Using the LCS external services CUA function.
v Using the access method services ALTER VOLUMEENTRY service. (For more
information on access method services, see z/OS DFSMS Access Method Services
for Catalogs.)
Once the attribute is set, it remains set until the volume is returned to scratch. To
request read-compatibility for a single usage of the volume, you can specify
LABEL=(,,,IN) on the DD statement of your JCL.
Demand Allocation with System-Managed Tape
For a system-managed tape request, by default, the JCL UNIT specification is
ignored. This enables the automatic class selection (ACS) routines to steer
allocation to a set of eligible libraries and devices and enables MVS allocation to
randomize across the eligible devices. This is the preferred and recommended way
to use the system-managed tape support. There may be times, however, when it is
beneficial to direct an allocation request to a specific device or set of devices. With
z/OS V1R11, you can specify the JCL keyword SMSHONOR on the UNIT
parameter or the dynamic allocation text unit DALSMSHR. When this keyword is
specified, MVS allocation will use the list of eligible devices returned by SMS and
the devices specified on the UNIT parameter and will allocate using the
intersection of the two lists. So, if a single device is specified, and that device is
one of the eligible devices returned by SMS, MVS allocation will allocate to the
device specified. And if an esoteric is specified on the UNIT parameter (one or
more devices), MVS allocation will allocate from the intersection of the two lists.
Devices that are not in both lists will be ignored. For more information on the
SMSHONOR keyword, refer to z/OS MVS JCL Reference, SA22-7597.

Load Balancing Considerations

This topic discusses load balancing considerations for scratch allocations and
specific allocations.
|

Scratch allocations
|
|
|
The default algorithm "EQUAL" works well if the libraries under consideration
have an equal number of online devices. For example, if two libraries are eligible
for a scratch allocation and each library has 128 devices, over time, each library
For non-specific (scratch) allocations, by default, MVS Device Allocation will first
randomize across all eligible libraries and then once a library is selected, will
randomize on the eligible devices within that library. In terms of the TS7700
Virtualization Engine, "library" is in reference to a composite library since MVS
allocation has no knowledge of the underlying clusters (distributed libraries). z/OS
also provides an alternate selection algorithm that will instead randomize scratch
allocations across all eligible devices. This alternate algorithm is available at z/OS
V1R11 and above, as well as z/OS V1R8 through V1R10 with APAR OA26414
installed.
Chapter 2. Planning for the Tape Library Support

will receive approximately half of the scratch allocations. Likewise, if one of the
libraries has 128 devices and the other library has 256 devices, over time, each of
the libraries will still receive approximately half of the scratch allocations
regardless of the number of devices in the library.
|
|
|
|
|
|
|
|
The alternate algorithm "BYDEVICES" will instead randomize scratch allocations
across all devices. For example, if two libraries are eligible for a scratch allocation
and each library has 128 devices, over time, each library will receive approximately
half of the scratch allocations, similar to the "EQUAL" algorithm. However, if one
of the libraries has 128 devices and the other library has 256 devices, over time, the
library that has 128 devices will receive approximately 1/3 of the scratch
allocations and the library that has 256 devices will receive approximately 2/3 of
the scratch allocations.
|
|
|
|
|
|
|
|
With the default algorithm "EQUAL", there may also be times when device
randomization within the selected library (or composite library) appears
unbalanced either across subsystems or across clusters in a TS7700 Virtualization
Engine (multi-cluster grid configuration running in balanced mode). As the
number of eligible subsystems increases, the likelihood of this imbalance occurring
also increases as the number of subsystems increases. If an imbalance is seen that
impairs the overall throughput rate of the library, consider enabling the
"BYDEVICES" algorithm.
|
|
|
|
|
|
|
|
|
|
|
The alternate "BYDEVICES" algorithm can be enabled through the ALLOCxx
PARMLIB member by using the SYSTEM TAPELIB_PREF(BYDEVICES) parameter
or it can be enabled (after an IPL) through the SETALLOC operator command by
issuing SETALLOC SYSTEM,TAPELIB_PREF=BYDEVICES. The alternate
"BYDEVICES" algorithm can be disabled by specifying the default "EQUAL"
algorithm through the SETALLOC command or the ALLOCxx PARMLIB member
in a similar manner. Before enabling the new load balancing support, care must be
taken to ensure that the desired results will be achieved. This is particularly
important if the libraries are being shared across multiple systems and the systems
may be at different levels of support or if manual actions had already been taken
to account for the behavior of algorithms used in previous releases.
|
|
|
Note: The SETALLOC operator command support is available only in z/OS V1R11
or later releases. In earlier z/OS releases, "BYDEVICES" must be enabled
through the ALLOCxx PARMLIB member.

Specific Allocations
For specific allocations (JES2-only environment), an ordered list of subsystems may
be returned to MVS allocation. The environments that support an ordered list
include the 3494 tape library and the TS7700 Virtualization Engine (Release 1.5 and
higher). With the TS7700 Virtualization Engine, the list of subsystems returned is in
cluster preference order. When an ordered list is returned, MVS allocation attempts
to allocate from the first subsystem returned in the list. If an online device is not
available within that subsystem, MVS allocation moves to the next subsystem in
the list and tries again until a device is chosen. The default algorithm "EQUAL",
supports an ordered list for the first seven subsystems returned in the list. After
that, if an eligible device is not found, all of the remaining subsystems are
considered equal. The alternate algorithm "BYDEVICES" removes the ordered
subsystem limitation. With the TS7700 Virtualization Engine (Release 1.5 or higher),
additional APAR OA30718 should also be installed prior to enabling the new
"BYDEVICES" algorithm. Without this APAR, the ordered subsystem list may not
be honored properly, causing specific allocations to appear randomized.

Balanced Mode in the TS7700 Virtualization Engine
|
|
|
|
|
|
A multi-cluster grid can be run in "Preferred" or "Balanced Mode". "Preferred
Mode" is where a host has virtual devices online to only one cluster in the grid. All
allocations are then directed to the devices in that one cluster. "Balanced Mode", on
the other hand, is where a host has virtual devices online to two or more clusters in
the grid. Allocations from the host could then select virtual devices from multiple
clusters.
|
|
|
|
|
|
|
|
|
|
|
|
With Release 1.5 of the TS7700 Virtualization Engine, during device allocation for a
specific (private) mount, the host will query the TS7700 to determine which cluster
is the “best” cluster to direct the allocation. With this query, the TS7700 will return
an ordered list of clusters with the preferred cluster being listed first. In doing so,
the TS7700 looks at whether a valid copy exists in a cluster (in cache or on
back-end tape) and other factors to determine the preferred cluster order. Device
allocation will then take into account this ordered list of clusters "subsystems"
when allocating a device. The allocation assist "affinity" function improves
performance by reducing cross cluster mounts. The allocation assist function is
supported in a JES2-only environment at z/OS V1R8 and above with APAR
OA24966. Refer to information APAR II14516 and “Load Balancing Considerations”
on page 51 for additional considerations when running in balanced mode.
Tape Encryption Support
Data encryption is an important tool for protecting against the possible misuse of
confidential information that could occur should tapes be lost or stolen. The 3592
Model E05 and the Model E06 support tape encryption with the actual encryption
and decryption of the data occurring outboard in the tape drive itself. References
in this document to "encryption-capable," mean that the encryption feature in the
drive has been enabled and the drive is capable of encrypting. In other documents,
this may be referred to as "encryption-enabled." For further discussion of
encryption-enablement and any MES capabilities, refer to IBM System Storage
TS1120/TS1130 Tape Drive and Controller Introduction and Planning Guide 3592 Models
J1A, E05, J70, and C06 and IBM System Storage TS1120/TS1130 Tape Drive and
Controller Operator Guide 3592 Models J1A, E05, J70, and C06.
The DFSMS tape subsystem encryption support allows specification by data class
that data is to be encrypted when stored on an encryption-capable tape drive. In
addition to this, the key label-related information that is used to encrypt the data
key (of a tape cartridge) can be specified through the DD statement (JCL, dynamic
allocation, and TSO ALLOCATE), data class or Encryption Key Manager (EKM)
defaults. When the encryption-capable tape drive needs a key to perform an
encrypted write, a data key is generated by the EKM. The data key used to encrypt
the data on a tape cartridge is itself encrypted (using the public key of a
public/private key pair) with either one or two key encrypting keys (KEKs) stored
in the key stores. The KEKs are maintained by the EKM through an existing key
store and are pointed to by the appropriate KEK label, also referred to as the key
label.
The communication path to the Encryption Key Manager (EKM) is across TCP/IP
with the choice to go either in-band or out-of-band for the key management flow.
With out-of-band key management, the communication path to the Encryption Key
Manager is handled by the control unit going directly to the Encryption Key
Manager. Then for in-band key management, the communication path to the
Encryption Key Manager is handled across ESCON/FICON with a new IOS proxy
Chapter 2. Planning for the Tape Library Support
53
interface in z/OS then handling the key exchange (across TCP/IP) with the
Encryption Key Manager. The IOS proxy interface supports both a primary and a
secondary encryption key manager.
An encryption capable 3592 Model E05 records in the non-encryption enterprise
format 1 (EFMT1) and enterprise format 2 (EFMT2) recording formats, and also
records in the encryption specific recording format (enterprise encrypted format 2
(EEFMT2)). The EEFMT2 recording format is supported across all of the 3592
media types (MEDIA5, MEDIA6, MEDIA7, MEDIA8, MEDIA9, and MEDIA10).
Although the 3592 Model E05 can record in a lower (EFMT1) and a higher
(EFMT2) recording format, an encrypted version of the lower recording format
(EFMT1) is not supported. Only the higher recording format (EFMT2) is supported
with an encrypted version (EEFMT2). You can also use the Performance Scaling
and Performance Segmentation data class options, applicable with MEDIA5 and
MEDIA9, with EEFMT2. The capacities of EMFT2 and EEFMT2 written tapes are
the same.
The 3592 Model E06 records in non-encryption enterprise format 2 (EFMT2) and 3
(EFMT3), as well as encrypted enterprise format 2 (EEFMT2) and 3 (EEFMT3). The
encryption formats (EEFMT2 and EEFMT3) are supported across all of the 3592
media types (MEDIA5, MEDIA6, MEDIA7, MEDIA8, MEDIA9, and MEDIA10).
You can also use the Performance Scaling and Performance Segmentation data
class options, applicable with MEDIA5 and MEDIA9, with EEFMT2 or EEFMT3.
The capacities of EMFT3 and EEFMT3 written tapes are the same.
When writing from the beginning of tape (file sequence 1, DISP=NEW), the
encryption capable 3592 Model E05 drive records in the non-encryption recording
format (EFMT2) by default; this default is set by z/OS OPEN processing. Lower
format EFMT1 and encryption format EEFMT2 must be explicitly requested
through data class. The 3592 Model E06 drives records in the non-encryption
recording format (EFMT3) by default. Lower formats EFMT2 and EEFMT2, as well
as the encryption format EEFMT3, must be explicitly requested through data class.
When writing from the beginning of the tape (file sequence 1, DISP=OLD), since
this processing does not go through the data class ACS routine, OPEN processing
determines if the previous usage of the tape was encrypted and if encrypted,
OPEN will explicitly set the EEFMT2 format (3592 Model E05) and the EEFMT3
format (3592 Model E06) with the volume's existing key management-related
information being used by the drive to encrypt the data.
For an encrypted tape cartridge, the cartridge stores not only the encrypted user
data but also critical key management-related information which is needed to
interact with the key manager when decrypting data on the cartridge. A mix of
data written in encrypted and non-encrypted formats is not supported on the same
tape cartridge; whether the data on a cartridge is written in encrypted format is
determined during OPEN processing, when the first file sequence on the tape is
written. If the first file written to a tape is in the encrypted format; all subsequent
files written to that tape cartridge are written in the encrypted format. All files
written to a cartridge in the encrypted format are encrypted using the same data
key. The exception to this is the volume label structure for the first file sequence,
which is encrypted using a key known to all encryption capable 3592 drives.
In the 3592 Model E05 and Model E06 environment (system-managed or
stand-alone), when writing from the beginning of tape (file sequence 1,
DISP=NEW), to request the encryption format, EEFMT2 or EEFMT3 is specified in
54
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
data class. OPEN processing passes key management-related information (such as
the key labels) to the drive for subsequent communication with the key manager.
For more information regarding the DFSMS encryption support, the encryption key
manager (EKM), and the IOS proxy interface to the encryption key manager, refer
to z/OS DFSMS Software Support for IBM System Storage TS1130 and TS1120 Tape
Drives (3592).
Performance Scaling Considerations
Performance scaling, also known as capacity scaling, is an optional data class
specification that allows you to contain data in a specified fraction of the tape,
yielding faster locate and read times.
The 3592 Model J tape subsystem supports the performance scaling option for the
IBM Enterprise Tape Cartridge (MEDIA5). The 3592-2, 3592-2E, and 3592- 3E drive
models support the performance scaling option on the IBM Enterprise Tape
Cartridge (MEDIA5) and on the IBM Enterprise Extended Tape Cartridge
(MEDIA9). Performance scaling, an optional specification, limits the data written to
the first 20% of the cartridge (the optimum scaled performance capacity)
improving the access time to the data. By default, the MEDIA5 or MEDIA9
cartridge is used to its full capacity. When written from loadpoint, the scaled tape
cartridge is reformatted to its full capacity format or to the performance scaled
format, depending on the assigned data class. If performance is of a higher priority
than capacity, consider using the performance scaling data class option or the
economy length cartridges.
Performance Segmentation Considerations
In addition to performance scaling, performance segmentation is a function that
allows you to divide the tape into longitudinal segments. Using this optional data
class specification, it is possible to segment the tape into two segments: one as a
fast access segment to be filled first, and the other as additional capacity to be
filled after the first segment is filled.
The 3592-J model supports the performance segmentation option on the IBM
Enterprise Tape Cartridge (MEDIA5). The 3592-2, , 3592-2E, and 3592-3E models
support the performance segmentation option on the IBM Enterprise Tape
Cartridge (MEDIA5) and the IBM Enterprise Extended Tape Cartridge (MEDIA9).
Where applicable, both the encryption and the non-encryption formats are
supported. When using the performance segmentation option, the overall capacity
of the cartridge is limited to 86.6% of the total capacity. The fast access segment
occuplies the first 20% of the cartridge, followed by the slower access segment. So,
for example, using EFMT2 or EEFMT2, a MEDIA5 cartridge written on a 3592
Model E05 has a capacity of 500 GB. If the cartridge is performance segmented, the
MEDIA5 cartridge is segmented into a 100 GB fast access segment and a 333 GB
slower access segment (for a total capacity of 433 GB). By default, the MEDIA5 or
MEDIA9 cartridge is used to its full capacity. When written from loadpoint, the
segmented tape cartridge is reformatted according to the assigned data class.
Because a segmented cartridge only has one physical partition and one EOV
indicator, data can only be written to the slower access segment after the fast
access segment has been filled. If an application wants to manage what data is
placed in which segment, the application needs to manually track and fill the fast
access segment before it can place less frequently accessed data in the slower
access segment.
Chapter 2. Planning for the Tape Library Support

Note: A cartridge can be defined for performance scaling or performance
segmentation, but not both.
Using the Tape Configuration Database to Manage Tape Volumes
The tape configuration database (TCDB) is an Integrated Catalog Facility user
catalog that contains tape volume and tape library records. You can use the TCDB
to maintain information about an IBM tape library and the volumes that reside
there.
Software Volume Categories
Table 4 identifies the software categories used in support of the ATL. see “TCDB

Scratch Threshold Setting and Scratch Allocation Implications
If a particular media type is being used in a tape library, IBM suggests setting a
scratch threshold value that is greater than zero. This value indicates that the
media type is being used in the library. This value also is used for scratch
56
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
threshold processing, allowing the CBR3660A message to be issued when the
number of scratch volumes falls below the scratch threshold setting.
|
|
|
You need to determine whether a library has scratch volumes for the media types
requested. A preferred library is one in which each media type requested (or
rewritable media inferred from a recording technology specification) for the
allocation request has a scratch volume count that is at or above the scratch
threshold value. In an ATL, the scratch count is derived from the hardware, so
scratch volumes that have been placed in the software error category are not
considered usable scratch volumes and are not included in the scratch count.
Unless the physical WORM media type is explicitly requested by data class
(MEDIA6, MEDIA8 and MEDIA10), it is excluded from the criteria when
determining whether a library is preferred.
The search for a prospective library uses the applicable media type. The applicable
media type is based either on the explicit type requested or based on the
applicable rewritable media type for the recording technology requested through
data class. If the library scratch threshold for the requested (or applicable) media
type is zero, the system assumes that the media type is not being used in the
library. This library is not considered to be a preferred library. A library with a
scratch threshold setting above zero and with the number of scratch volumes at or
greater than the threshold value becomes a candidate for the request and is a
preferred library. However, a library with a scratch threshold setting above zero
and with a scratch count below the threshold value is not considered to be a
preferred library.
If you do not use data class to specify a particular media type or recording
technology, all rewritable media types are applicable for the scratch request. All
media types with a nonzero scratch threshold value are examined to determine if
their scratch count is above or below the threshold. If any of the media types in
the library are below the threshold, the library is not preferred. If all the media
types with a nonzero scratch threshold setting are at or above threshold, then the
library is preferred. If the scratch threshold for all the media types are set to zero,
OAM cannot determine which media types exist in the library. By default, the
library is considered preferred as it is likely that there are scratch volumes for the
media type. However, as the example below explains, this situation can lead to a
workload imbalance among multiple libraries depending on whether data class is
used for the media interchange.
Recommendation: Set a scratch threshold value for all media types that are being
used in a library. In some situations, a workload imbalance could occur if some of
the libraries that are eligible for the scratch request set a nonzero scratch threshold
value for a particular media type and other libraries leave the scratch threshold
value for that media type at zero. If a media type is to be used in a library, you must
set a nonzero scratch threshold value in each of the libraries that are eligible for the scratch
allocation.
The following is an example where the scratch threshold setting would impact
workload balancing if some of the eligible libraries had specified a scratch
threshold value and other libraries had not. This scenario uses data class to
explicitly request MEDIA2. The following three libraries are eligible for the request.
Example:
v Two VTS libraries (ATLVTS1 and ATLVTS2) have zero MEDIA2 threshold
settings but have 2000 MEDIA scratch volumes in each library.
Chapter 2. Planning for the Tape Library Support
57
v One VTS library (ATLVTS3) has 1000 set for the MEDIA2 scratch threshold and
has 2000 MEDIA2 scratch volumes.
When applying scratch threshold factors for the MEDIA2 request, the first two
libraries (ATLVTS1 and ATLVTS2) are marked below threshold as OAM assumes
that MEDIA2 is not being used in the library because the scratch threshold values
are set to zero. The third library (ATLVTS3) is a preferred library because the
number of scratch volumes is greater than the scratch threshold setting. Until the
third library (ATLVTS3) falls below its scratch threshold for MEDIA2, ATLVTS3
with the specified scratch threshold of 1000 will be preferred and scratch requests
probably will be allocated to drives in this library, causing a scratch threshold
workload imbalance along the three libraries. In this scenario, providing a
reasonable or equivalent scratch threshold setting for the first two VTS libraries
creates a better balance for MEDIA2 scratch requests.
However, in the above example, if data class is not being used to request a
particular media type, each of the three libraries are considered to be above
threshold and are preferred, resulting in a better workload balance across the three
libraries. With the two VTS libraries (ATLVTS1 and ATLVTS2) not having any
scratch threshold values set, by default, these libraries would be considered above
threshold.
Recommendation: Always set a scratch threshold value that is greater than zero if
a particular media type is to be used in a library.
TCDB Volume Error Status Field and Software Error Category
in an Automated Tape Library
When a hardware or software error is detected, the volume error status field in the
tape configuration database (TCDB) is updated to reflect the error, and the volume
may also be placed in the software error category in the library manager database.
More specifically, when a software error is detected for a scratch volume, this
results in the volume being placed in the software error category in the library
manager database. The setting of an error category prevents the volume from
being selected for future nonspecific (scratch) mount requests. In addition, the
error status field in the TCDB volume record is updated to reflect the software
error condition.
Detecting Software Errors for Private Volumes
A software error detected for a private volume results in an update to the volume
record in the TCDB with the appropriate error status; however, since private
volumes are requested by volser and not by a category value, there is no need to
place private volumes in the software error category.
Detecting Hardware Errors for Volumes
When a hardware error is detected (for either scratch or private volumes), the error
is tracked in the library manager database and in the TCDB. Since the library
manager tracks hardware-related errors for volumes, there is no need to place the
volume in the software error category.
Resetting the Volume Error Status Field
There are several ways to reset the volume error status field in the TCDB and, if
applicable, move the volume out of the software error category:
v General use programming interface CBRXLCS FUNC(CUA) can be used to
change the volume’s use attribute from SCRATCH to PRIVATE, PRIVATE to
58
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
SCRATCH, PRIVATE to PRIVATE, or SCRATCH to SCRATCH. See “Change Use
Attribute (CUA)” on page 147 for more information on how use this interface. If
the only purpose of the CBRXLCS invocation is to reset the volume error status
field, CBRXLCS FUNC(CUA) from SCRATCH to SCRATCH or PRIVATE to
PRIVATE accomplishes this (it is not necessary to actually change the volume’s
use attribute). Invoking CBRXLCS FUNC(CUA) will also move a volume out of
the software error category.
v The ISMF volume ALTER command or line operator can be used to update
specific fields in the TCDB volume record, including the volume error status
field. If no other changes to the volume are required, invoke ISMF ALTER to
change the volume’s use attribute from PRIVATE to PRIVATE or SCRATCH to
SCRATCH. Changing the volume’s use attribute from SCRATCH to PRIVATE or
from PRIVATE to SCRATCH using ISMF ALTER also resets the volume’s error
status field. Invoking ISMF ALTER against a volume record also moves a
volume out of the software error category.
v If a volume is ejected from the library where it resides and is reentered into the
same library, or a different library, the volume error status field and software
error category resets upon entry.
v A successful audit of a volume resets a hardware error in the TCDB (such as
misplaced volumes), but it does not clear a software error in the TCDB. Since
hardware errors do not result in the volume’s category being changed, audit
never alters the setting of a volume in the error category. If a scratch volume has
a software error associated with it, a successful audit of the volume leaves the
volume error condition set in the TCDB and leaves the volume in the error
category.
Note: Also keep in mind that resetting a hardware error condition in the
volume’s TCDB volume record does not clear the condition in the library
manager database.
v When DFSMSrmm is used, EDGUTIL with PARM='MEND(SMSTAPE)' can reset
some error status values.
Displaying Scratch Volume Counts
Whenever you use the DISPLAY SMS,LIBRARY command, the scratch volume
counts that are displayed reflect the number of scratch volumes in the scratch
media categories. If a scratch volume is in the software error category, it is not
included in this count because it is not considered a usable scratch cartridge.
Displaying Software Error Category Count
Use the DISPLAY SMS,LIBRARY to display the number of scratch volumes
currently in the software error category associated with a particular library. See
“Displaying Library Detail Status” on page 121 for more information on this
command.
TCDB Volume Error Status Field and the MTL
When a software error is detected, the volume error status field in the tape
configuration database (TCDB) is updated to reflect the error, however there is no
equivalent software error category. In a manual tape library environment, the
setting of this field is for informational use only. An operator can attempt to mount
a cartridge with an error condition and if the error condition no longer exists, it
will be cleared. Additionally, see“Resetting the Volume Error Status Field” on page
58 for more information.
Chapter 2. Planning for the Tape Library Support
59
TCDB Volume Expiration Date
When an expiration date is specified when writing a data set, the volume’s
expiration date is recorded in the TCDB Volume Expiration Date field. If an
expiration date pre-exists for the volume, the later date becomes the new
expiration date. If the pre-existing date is later than the new date, the pre-existing
date is retained. However, if special “never expire” dates 99365 or 99366 are
involved, these special dates take precedence. Special “never expire” dates appear
in ISO format as 1999/12/31 for 99365, and 1999/12/32 or 1999/13/01 for 99366.
Console Name Message Routing
Through console name message routing support, an MVS console can be associated
with each tape library. Instead of routing library specific messages to all consoles
associated with the messages’ routing codes, they are routed to a specific library
console.
For critical messages that need to be broadcast to a wider audience, the messages
will be issued to the library console and to the MVS consoles associated with the
routing codes. For example:
CBR3758E
Library library-name operation degraded.
Associating Console Names with Tape Libraries
When the storage administrator defines a tape library using the ISMF Tape Library
Define panel, an MVS console name can be associated with the tape library. The
console name is stored in the library record in the TCDB. The console name is also
passed to the following installation exits:
v Cartridge Entry Installation Exit (CBRUXENT)
v Cartridge Eject Installation Exit (CBRUXEJC)
v Change Use Attribute Installation Exit (CBRUXCUA)
v Volume Not in Library Installation Exit (CBRUXVNL)
The console name specified on the ISMF Tape Library Define panel must also be
defined in the CONSOLxx member of PARMLIB for each system connected to the
library.
Defining an Alternate z/OS MCS Console
You can define an alternate z/OS MCS console using an active 3270 session on the
library manager machine console. You may want to have an active z/OS MCS
console on the same machine running the library manager; this allows the person
managing the library manager console to perform the following tasks:
v Display and change the status of the tape library and its associated tape drives
v Display the host status of a tape volume within the tape library
v Display or change the status of an SMS TAPE storage group
v Receive library specific MVS messages
Taking Advantage of Console Name Message Routing
To take advantage of console name message routing, the installation must
configure each sysplex sharing the library in one of the following ways:
v In a JES3 environment, the console name associated with the library must be
attached to the current JES3 global processor, and must be switchable to any
local processor capable of becoming the global. The console should be defined in
the JES3 initialization deck as an MCS console by specifying TYPE=MCS and
60
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
using the UNIT keyword on the CONSOLE statement (not the DEVICE
statement) to establish the logical association to the actual device number on the
individual processors.
v In a cross system communication facility (XCF), define a physical console to
receive tape library-specific messages. Make sure each system in the sysplex has
that console defined with the same name. A separate console can be used per
library.
v In a JES2 environment without XCF, each system must have a separate physical
console, and all consoles must have the same name.
If more than one sysplex shares the library, each sysplex must have a separate
physical console. If there is a single TCDB, then all consoles must have the same
name. If there is a separate TCDB for each sysplex, then each sysplex may have a
unique console name.
Sharing a Tape Library Among Multiple Systems
The ATLDS and the MTL may be shared among multiple systems and, in some
cases, among multiple SMS complexes. In all cases, it is the responsibility of the
installation to ensure that an individual library-resident tape drive not be allocated
by two systems concurrently. This means that the tape drive can be online to only
one SMS complex. In addition, if the SMS complex where the tape drive is online
does not have JES3 or equivalent support for the sharing of tape drives, the tape
drive can be online to only one system. To ensure that volumes intended for VM
use are not made available to SMS, the installation should assign a recognizable
volume serial number range to VM and a different range to SMS. The cartridge
entry installation exit, through use of the ignore return code, prevents SMS from
using the wrong set of volumes. See Figure 3 on page 62 for an example of sharing
a tape library among systems.
Chapter 2. Planning for the Tape Library Support
61
Figure 3. Sharing a Tape Library among Multiple Systems
The ATLDS and the MTL can also be shared among multiple SMS complexes,
provided the following restrictions are observed:
v There must be a single shared tape configuration database among all systems in
all SMS complexes. This means there is one general volume catalog, and at the
most one specific volume catalog for each valid initial volser character.
v The library name associated with the hardware library ID must be the same in
each SCDS. The library console name and the scratch volume message
thresholds must also be the same. The entry default data class, entry default use
attribute, eject default, and system connectivity status can be different in each
SCDS.
v There is a single pool of scratch volumes to be shared among all the SMS
complexes. This pool consists of separate library manager categories for each of
the supported media types.
Managing Private Volumes in a Library Sharing Environment
There are two options for the management of private volumes:
1. The simpler option allows sharing of private volumes among all systems in all
SMS complexes. This requires that each SCDS have the same set of tape storage
group definitions. All storage groups with the same name must reside in the
62
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
same set of libraries, though the storage group state on each system in the SMS
complex can vary. The cartridge entry installation exit must also be the same on
all systems.
2. The other option, which proves more difficult, is to restrict access to private
volumes to a single SMS complex. Each SCDS can have its own set of tape
storage groups; an attempt to use a private volume in a SMS complex where its
assigned storage group does not exist causes the job to fail. When existing
private volumes are entered into the library, the cartridge entry installation exit
must recognize the volumes which belong to its particular SMS complex. If this
is not possible, the volumes may be assigned to the blank storage group at
cartridge entry time, then selectively assigned to the proper storage group by
the storage administrator at some later time.
No matter which private volume management mechanism is selected, it should be
noted that a permanent association between the volume and a particular SMS
complex is not possible. When the volume use attribute is changed from private to
scratch, the volume becomes eligible for use on any system sharing the ATLDS, or
the MTL.
Partitioning Tape Libraries among Multiple Sysplexes
Partitioning a tape library is dividing the resources in the library—tape drives and
tape volumes—among multiple systems or sysplexes, or both, for their exclusive
use. The set of tape drives and tape volumes which belong to one or more systems
or sysplexes, or both may not be used by a nonsharing system or sysplex without
manual intervention. Each sharing partition may be either an MVS platform or a
non-MVS platform. A single MVS platform may consist of one or more systems or
sysplexes, or both, connected to a shared tape configuration database (TCDB); this
group of sharing systems or sysplexes, or both, is referred to as a TCDBplex.
Multiple TCDBs may each contain configuration information about the library and
some subset of the volumes in the library. Partitioning may thus be viewed as
dividing a physical library into multiple logical libraries, with each logical library
(TCDBplex) represented by one TCDB. Figure 4 on page 64 provides a pictorial
description of library partitioning.
Chapter 2. Planning for the Tape Library Support
63
Figure 4. Partitioning a Tape Library
Changing the Library Manager Category Assignments in an
ATLDS
To partition a library among multiple TCDBplexes requires separation of the
scratch pools; that is, each TCDBplex must have a separate library manager
category for each scratch media type. For logical completeness, the error and
private volume categories should also be unique to each TCDBplex. The default
category assignments are described in Table 4 on page 56.
To change the default category assignments, specify the categories in PARMLIB
member DEVSUPxx. The category specification parameters enable the installation
to change the default category assignments associated with a system or sysplex, or
both. It is the responsibility of the installation to ensure that all systems or
sysplexes, or both, associated with the same TCDB (TCDBplex) use the same
category assignments. For a discussion of the partitioning-related DEVSUPxx
parameters, see z/OS MVS Initialization and Tuning Reference.
In a partitioned library, it is recommended that the installation use DEVSUPxx to
change the default categories associated with each TCDBplex. This means that no
TCDBplex uses the default categories, so there are no volumes in those categories.
If the DEVSUPxx parameters are inadvertently removed from one system, scratch
mount requests are directed to the empty default categories and the mount
requests fail. If there is a TCDBplex that is using the default categories, volumes
may be mounted by the system where the DEVSUPxx parameters were removed. If
64
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
a scratch volume from a default category is mounted on the system where the
parameters were removed, it is not used since there is no tape volume record in
the TCDB. The volume is assigned to the error category with resultant disruption
in library operations in the TCDBplex that owns the default categories.
Processing Default Categories When Using DEVSUPxx in an
ATLDS
If an installation has been running with its tape libraries in unpartitioned mode for
some period of time, the tape volumes will already be assigned to default
categories. When the partitioning related DEVSUPxx parameters are used, special
processing is necessary to move volumes to the new categories established through
DEVSUPxx:
v Modify the DEVSUPxx PARMLIB member associated with each system or
sysplex, or both, in each TCDBplex.
v If the library is a Virtual Tape Server (VTS) or a Peer-to-Peer VTS and you wish
to take advantage of the library's nonspecific (scratch) mount performance,
define the Fast Ready attribute at the library manager for the DEVSUPxx scratch
categories to be used at the library.
v IPL all systems in the TCDBplex to activate the DEVSUPxx changes.
v Ensure that no jobs which require scratch mounts in a library are run. This may
be done by varying all library-resident tape drives offline to all systems.
v Start the OAM address space and make sure that all tape libraries are online.
The tape drives must remain offline.
v Obtain a list of volumes whose storage group name is ‘*SCRTCH*’ using the
ISMF Mountable Tape Volume Application. It is a good idea to do this one
library at a time by also specifying the library name.
v Use the ISMF ALTER command (not the line operator) to change the volume use
attribute for all volumes in the list from scratch to scratch. This causes the
library manager category for each volume to be changed from the default value
to the new value established through DEVSUPxx. All volumes in the default
scratch categories and in the error category are changed to the new DEVSUPxx
scratch categories.
v It is not necessary to change the category of private volumes. When a private
volume is returned to scratch, its category will be changed to one of the new
scratch categories.
v Vary the tape drives online as appropriate, and start to run normal tape job
streams.
Separating the Volumes for Use in Different TCDBplexes
To ensure that only one TCDBplex has access to any single tape volume, assign a
separate range of volume serial numbers to each TCDBplex. Cartridge Entry
Installation Exit (CBRUXENT) may be used to accept volume serial numbers in the
range assigned to the TCDBplex when they are entered, but to ignore volume
serial numbers that are outside the range. Each system in the TCDBplex must have
the same installation exit. Each different TCDBplex must have installation exit logic
that accepts a different range of volume serial numbers.
DFSMSrmm offers facilities (the PRTITION or the REJECT ANYUSE commands in
PARMLIB member EDGRMMxx) that allows an installation to specify partitioning
information for this TCDBplex. See “DFSMSrmm Support for Sharing a Tape
Library Dataserver” on page 67.
Chapter 2. Planning for the Tape Library Support
65
Handling Tape Drives in a Partitioned ATLDS
When a tape library is partitioned, each tape drive may be online in only one
sysplex. If the sysplex does not have JES3 or equivalent support for the sharing of
tape drives, the tape drive may be online to only one system within the sysplex. A
tape drive may be switched from one sysplex to another by varying the drive
offline in the old sysplex and then varying it online in the new sysplex.
To provide optimum tape library performance, assign one of the scratch media
types to be preloaded into the integrated cartridge loader (ICL) on each 3495
library-resident tape drive. Varying the drive offline in one place and then online
in another place does not change which media type has been assigned to the ICL.
If the drive is now online in a different sysplex, the category for the preloaded
scratch media type is not one that is defined in the new sysplex. A LIBRARY
DISPCL or DISPDRV command displays the category as currently assigned. As
part of switching the device to the new sysplex, the operator should use LIBRARY
SETCL to assign the scratch media type; this causes the assignment of a category
that is defined in the new sysplex. In response to the command, the Library
Manager unloads the cartridges that are currently in the ICL and replaces them
with cartridges from the scratch category in the new sysplex. See “Displaying the
Cartridge Loader Scratch Media Type” on page 112, and “Setting the Cartridge
Loader Scratch Media Type” on page 113 for more information.
Handling Tape Drives in a Partitioned MTL
When a tape library is partitioned, each tape drive may be online in only one
sysplex. If the sysplex does not have JES3 or equivalent support for the sharing of
tape drives, the tape drive may be online to only one system within the sysplex. A
tape drive may be switched from one sysplex to another by varying the drive
offline in the old sysplex and then varying it online in the new sysplex.
To provide optimum tape library performance, first determine which TCDBplex is
to own the cartridges in the cartridge loader. For the systems associated with that
TCDBplex, use the LIBRARY SETCL command to associate the cartridge loader
with a particular media type or ANY (this must be done on each system). To
ensure that the other non-owning TCDBplex systems don't attempt to index
another system's cartridges, use the LIBRARY SETCL command on those systems
to set the cartridge loader to NONE. Also by default, after an IPL the cartridge
loader will be set to NONE. See “Displaying the Cartridge Loader Scratch Media
Type” on page 112, and “Setting the Cartridge Loader Scratch Media Type” on
page 113 for more information.
Ability to use MTL Drives as Stand-Alone
Through use of the MTLSHARE keyword, a manual tape library device on one
system can be used on another system as a non-library (stand-alone) device.
Specification of the MTLSHARE keyword on the non-MTL (stand-alone) systems
also ensures that the cartridge loader can only be indexed on the systems using the
device as a manual tape library device. This prevents the stand-alone environment
from using scratch cartridges assigned to the manual tape library. For additional
information see “Manual Tape Library Considerations” on page 70.
Sharing Tape Volumes between an SMSplex and a Non-MVS
Platform
All library-resident tape volumes used by an SMSplex must be defined in the tape
configuration database. This means that cartridge entry must occur on an SMS
system. Therefore, all volumes to be used exclusively by SMS, and all volumes to
be shared by SMS and a non-MVS platform must be entered on an SMS system.
66
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Either the Cartridge Entry Installation Exit or DFSMSrmm may be used to control
which cartridges are accepted. Other considerations include:
v If the volumes already contain useful data, they should be assigned the private
volume use attribute.
v If the volumes do not contain useful data and they are to be written on the
non-MVS platform, they should be assigned the private volume use attribute to
prevent their use as scratch volumes by SMS.
v If the volumes do not contain useful data and they are to be written on the SMS
system, they may be assigned the scratch volume use attribute.
v All references to the volumes from a non-MVS platform should be specific
volume serial number references.
v Private volumes should be returned to scratch only on an SMS system.
v An attempt to mount a volume on one platform will fail if the volume is already
in use on another platform.
v Cartridges should be ejected only from an SMS system.
DFSMSrmm Support for Sharing a Tape Library Dataserver
DFSMSrmm provides support for easier installation control over sharing a tape
library dataserver. DFSMSrmm provides a cartridge entry installation exit that can
be used to help partition volumes in a tape library dataserver across multiple
sysplexes. This can include both VM and MVS platforms, as well as multiple
SMSplexes. Support for partitioning with VM is provided based on volume
naming convention, and at the individual volume level for volumes defined to
DFSMSrmm on MVS. With a single tape configuration database (TCDB) across
multiple MVS systems and complexes, a single DFSMSrmm control data set is
typically used. With a single DFSMSrmm control data set, all volumes can be used
on any or all systems with no partitioning possible. Then with carefully selected
PRTITION and OPENRULE parameters for DFSMSrmm, you can also partition the
tape library dataserver across multiple MVS systems. In doing so, there is typically
one-to-one correspondence of tape configuration database TCDB to DFSMSrmm
control data sets. You must use the DFSMSrmm facilities to ensure that a single
volume is defined in only a single tape configuration database and a single
DFSMSrmm control data set. See z/OS DFSMSrmm Implementation and Customization
Guide for implementation details for these and any additional scenarios. Also refer
to the IBM Redbook Guide to Sharing and Partitioning IBM Tape Library Dataservers.

Chapter 3. Installing Your Tape Library Support
This chapter explains how to install and customize your tape library environment.
To simplify the installation process, a library of sample jobs and other useful data
sets (SAMPLIB) is shipped with the product. This chapter includes instructions for
using SAMPLIB (Appendix A, “SAMPLIB Members,” on page 255 contains listings
of the SAMPLIB members), and an installation checklist to assist you with the
software installation of your tape library. Before running any SAMPLIB member,
remember to change the JCL to reflect your installation’s requirements (for
example, accounting information and data set names).
Verifying Prerequisites
Before proceeding with the installation checklist, verify that the hardware and
media requirements “Analyzing Your Hardware Environment” on page 43 have
been met. Ensure that all the prerequisites have been installed and thoroughly
tested to verify that they operate correctly in your processing environment before
proceeding with any other installation steps. For more information on prerequisites
for DFSMS and z/OS, see z/OS Migration.
Outboard Policy Management Coexistence Considerations
Outboard policy management is supported at OS/390® V2R10 and above. There is
no separate coexistence support at the full-support release level. Once the
full-support PTFs have been installed, for a library with outboard policy
management support enabled, the ACS-routine-assigned Storage Management
Subsystem (SMS) constructs are passed to the library during mount processing for
file sequence 1 (DISP=NEW). However, for specific policy actions to be taken at the
library, policies must have been established at the library with defined actions for
these SMS construct names. Otherwise, the policies are created by the library by
using default actions.
The following results occur when the coexistence support is installed on systems
that share an outboard policy management-enabled library:
v Volumes that are returned to scratch from the coexistence and full-support level
systems are assigned default policy names of "blanks" at the library.
v A volume's existing policies and actions remain in effect for mount requests on
the systems that have the coexistence support installed. This includes a private
volume that is mounted and rewritten from the load point.
Likewise, when a scratch volume is mounted on a system that has the
coexistence support installed, the volume when it is returned to scratch has
default policy names of "blanks" and actions that are assigned at the library.
These default policy names and actions remain set for the volume.
v Also at the coexistence level, multivolume data sets that are extended to another
volume are processed the same way as at the full-support level. The policies that
are assigned to the previous volser are assigned to the subsequent volume so
that the volumes that are associated with the multivolume data set have the
same policies in effect.
v To prevent volumes with policy names from being left in the insert category,
cartridge entry processing at the coexistence and full-support level are the same.
© Copyright IBM Corp. 1993, 2010
69
Any existing policy names for the volume at the time of entry or import are
passed to the cartridge entry installation exit.
Recommendation: Install the appropriate coexistence or full-function outboard
policy management support on all systems that share an outboard policy
management-enabled library to reduce confusion and maintain policy consistency.
Import/Export Considerations for the 3494 VTS
Logical volumes exported from a 3494 VTS library with no outboard policy
management support do not have policy construct data included on the export
stacked volume. When these volumes are imported into a library with outboard
policy management support, default policy names (blanks) are assigned to the
volumes unless explicitly specified through the Import List file.
Logical volumes exported from a library with outboard policy management
support have policy construct data included on the export stacked volume.
Libraries with no outboard policy management support are capable of importing
logical volumes from a library with outboard policy management support by
ignoring the policy construct data.
Import List 01 and Import List 02 are supported by libraries with outboard policy
management support; however, only Import List 01 is supported by libraries with
no outboard policy management support. For more information regarding Import
List 02, see “SAMPLIB Member CBRSPPIP” on page 313.
Manual Tape Library Considerations
The system keyword MTLSHARE enables MTL-defined devices to be treated as
stand-alone devices. This keyword can be specified to either override the IODF
MTL definition or without a shared IODF, to indicate that stand-alone devices are
being used elsewhere as manual tape library devices. Usage of this keyword tells
the system that the cartridge loaders are to be owned by the systems that
recognize and treat the devices as MTL resident library devices. This prevents MTL
resident scratch volumes from being indexed and incorrectly used by the
stand-alone systems. The MTLSHARE keyword (if used) must be specified in the
LOADxx member of SYS1.IPLPARM or SYS1.PARMLIB. With a shared SCDS, the
manual tape library should only be enabled on those systems that are using the
devices in the context of a manual tape library.
TDSI Coexistence Considerations
Built into the base support are coexistence considerations for up-level media types
and recording technologies. This support recognizes when it is dealing with
up-level tape device selection information (TDSI) information and acts accordingly.
For example, during cartridge entry processing, a volume whose media type
and/or recording technology is not supported at this system level will be left in
the insert category to be processed by a system that understands the up-level TDSI
values. Also, if the TCDB is being shared across multiple system levels, volume
records containing up-level TDSI information will not be displayed through ISMF.
This support also prevents operator commands, job requests, and CBRXLCS
requests for up-level volumes from being honored. This prevents the system from
processing up-level media that it does not fully understand.

3590 Model H Coexistence Considerations
The 3590 Model H is supported in the base release at z/OS V1R5 with full support
PTFs available at earlier release levels. However, device services coexistence
support is needed to prevent the 3590 Model H from coming online on a system
that does not have the full support installed. This coexistence support is built into
their full support PTF. Without the coexistence support installed, the 3590 Model H
appears to lower-level systems as a 3590 Model B, which results in an incorrect
recording technology being recorded in the tape configuration database (TDSI) and
in potential job failures.

Considerations” on page 70.

3592 Model J Coexistence Considerations
Coexistence support for the base 3592 support and MEDIA5 is provided in OS/390
V2R10 and above by installing the needed full-support PTFs without the Device
Services enabling PTF. Device services coexistence support prevents the 3592
Model J devices from coming online on a system that does not have all of the
full-support PTFs installed. Installation of the base support enabling PTF brings in
all of the needed full-support PTFs and enables the base 3592 support on that
system.
In support of the additional 3592 media types, MEDIA6, MEDIA7, and MEDIA8,
coexistence support is also provided at OS/390 V2R10 and above. However, since
full support for these media types is only available at z/OS V1R3 and above,
coexistence support is provided at OS/390 V2R10 through the installation of
separate coexistence specific PTFs. At the full support release levels, coexistence
support is provided by installing the needed full-support PTFs without the Device
Services enabling PTF. As with the base 3592 support, installation of this support's
enabling PTF will bring in all of the needed support PTFs for MEDIA6, MEDIA7,
and MEDIA8. If the system is enabled for the base 3592 support and is not enabled
for the additional media support, only MEDIA5 volumes are supported on 3592
drives. Before using the additional 3592 media types, ensure that all of the support
code is installed as appropriate (full or coexistence).
Before using MEDIA6, MEDIA7, or MEDIA8 in the tape library environment
(ATLDS or MTL), ensure that all 3592 drives in the library are at a microcode level
that supports the additional 3592 media types. Otherwise, a drive without the
proper microcode support might be allocated for a mount request resulting in
potential job failures.
3592 Model E05 Coexistence Considerations
Coexistence support for the 3592 Model E05 is provided at z/OS V1R4 and above
by installing the needed full-support PTFs without the Device Services enabling
PTF. In addition to this, existing device services support (with APAR OA02207)
prevents the 3592 Model E05 devices from coming online on a system that does
not have all of the full-support PTFs installed. Installation of the Devices Services
enabling PTF brings in all of the needed full-support PTFs. You must install the

needed coexistence support on systems that will not have all of the 3592 Model
E05 support installed. Even with full support enabled, the z/OS V1R4 system does
not support the MEDIA9 and MEDIA10 media types; these two media types are
supported beginning with the z/OS V1R5 release. For more information on
existing tape library coexistence support, see “TDSI Coexistence Considerations”
on page 70.
Encryption-Capable 3592 Model E05 Coexistence Considerations
Coexistence support for the encryption-capable 3592 Model E05 is provided at
z/OS V1R4 and above by installing the needed full-support PTFs without the
Device Services enabling PTF. Installation of the Devices Services enabling PTF
brings in all of the needed full-support PTFs. Device Services provides coexistence
support which allows the encryption-capable 3592 Model E05 devices to come
online as 3592-2 drives (not encryption capable) if the system does not have all of
the full-support PTFs installed. You must install the needed coexistence support on
systems that do not have all of the 3592-2E encryption support installed. Even with
full support enabled, the z/OS V1R4 system does not support the MEDIA9 and
MEDIA10 media types; these two media types are supported beginning with the
z/OS V1R5 release. For more information on existing tape library coexistence
support, see “TDSI Coexistence Considerations” on page 70.
Encryption-Capable 3592 Model E06 Coexistence Considerations
Coexistence support for the 3592 Model E06 is provided at z/OS V1R7 and above
by installing the needed full-support PTFs without the Device Services enabling
PTF. In addition to this, existing device services support prevents the 3592 Model
E06 devices from coming online on a system that does not have all of the
full-support PTFs installed. Installation of the Devices Services enabling PTF brings
in all of the needed full-support PTFs. You must install the needed coexistence
support on systems that will not have all of the 3592 Model E06 support installed.
For more information on existing tape library coexistence support, see “TDSI
Coexistence Considerations” on page 70.
Considerations When Running z/OS as a Guest under z/VM
If z/OS is run as a guest under the z/VM operating system, STDEVOPT LIBRARY
CTL must be specified in the VM directory entry for the VM user ID under which
the z/OS guest operating system is IPLed. The STDEVOPT statement specifies the
optional storage device management functions available to a virtual machine. The
LIBRARY operand with CTL tells the control program that the virtual machine is
authorized to issue tape library commands to an IBM Automated Tape Library
Dataserver. If the CTL parameter is not explicitly coded, the default of NOCTL is
used. NOCTL specifies that the virtual machine is not authorized to issue
commands to a tape library, and this results in an I/O error when z/OS tries to
issue a command to the library. For further information on the STDEVOPT
statement, see z/VM CP Planning and Administration and z/VM Running Guest
Operating Systems.
Tape Library Installation Checklist
This section provides a checklist to assist in your installation of the tape library
dataserver support. See “Installation Procedures” on page 74 for more detailed

Installation Procedures
This section provides details to assist in the installation of tape library support in
your storage environment.
Building the Library Inventory
1Build the library inventory.
To initially load the library manager inventory in an ATLDS, insert tape cartridges
into the library storage slots and start the teach operation at the library manager
console. In a virtual tape server (VTS) library, the logical volumes are identified at
the library manager console through volume serial number ranges. All cartridges
are placed in the insert category by the library manager for later cartridge entry
processing by the host. It is later during OAM address space initialization and the
host going through vary online processing that the cartridges in the insert category
are processed and the records in the TCDB are created. As the host processes each
cartridge in the insert category, the cartridge entry installation exit (CBRUXENT) is
invoked to approve or deny the entry of the cartridge.
If the volumes in the library are shared between an MVS and a non-MVS platform,
see “Sharing Tape Volumes between an SMSplex and a Non-MVS Platform” on
page 66. If the volumes are already owned by a non-MVS platform and are no
longer in the insert category, the TCDB volume records must be manually created
in order for MVS to have use of the volumes. Because this bypasses the Cartridge
Entry Installation Exit, the volumes may also need to be added to your tape
management system.
74
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
To initially load the MTL inventory, the general use programming interface,
CBRXLCS FUNC=MCE, or the LIBRARY ENTER command may be used. Also
check with your tape management system to determine what support they may
provide for building the MTL inventory.
Changing System Libraries
After using SMP/E to install z/OS, change the system libraries using the following
procedures.
2Update PARMLIB.
2aUpdate IGDSMSxx PARMLIB member.
Update the IGDSMSxx PARMLIB member to include the following OAM-related
keywords:
OAMPROC(procname)
Optional parameter that specifies the procedure name to be used to start the
OAM address space. Specify this keyword to start the OAM address space
automatically during IPL. The procedure name can be from 1 to 8 characters,
and there is no default.
OAMTASK(taskid)
Optional parameter that specifies the identifier to be used to start the OAM
address space. If you specify this keyword without the OAMPROC keyword,
it is ignored. This identifier can be from 1 to 8 characters, and there is no
default. Code the OAMTASK keyword if you prefer to use an identifier other
than the procname when starting the OAM address space. taskid is the identifier
that is used on the START command. taskid corresponds to the ‘identifier’
parameter of the MVS START command documented in z/OS MVS System
Commands.
These optional parameters are used when you want the OAM address space to
start automatically as part of SMS initialization. “OAM” can be used as the
procedure name, the task identifier, or both.
Note: For examples of the OAM START command and more information
concerning the identifier parameter, see “Starting OAM” on page 100. For
more information on the START command, see z/OS MVS System Commands.
Also, for more details concerning these optional parameters and other
keywords associated with the IGDSMSxx PARMLIB member, see z/OS
DFSMSdfp Storage Administration.
2bUpdate IEFSSNxx PARMLIB member.
Add or update the OAM1 entry in the IEFSSNxx PARMLIB member.
SUBSYS SUBNAME(OAM1) INITRTN(CBRINIT) INITPARM('[TIME=GMT][,MSG=xx]')
where:
TIME=GMT
Specifies that OAM uses Greenwich Mean Time. If this option is omitted,
or if any value other than GMT is specified, local time is used. For tape
library volumes, this time specification affects the date set in the tape
configuration data base (TCDB) volume record when a volume is
entered/imported into or ejected/exported from a tape library.
Chapter 3. Installing Your Tape Library Support
75
MSG=xx Specifies the format of OAM message text:
v MSG=EM specifies message text is in mixed-case English.
v MSG=EU specifies message text is in uppercase English.
If the MSG parameter is omitted, the default is mixed-case English.
OAM1 is the name of the subsystem, and CBRINIT is the name of the initialization
module executed at IPL time.
2cUpdate CONSOLxx PARMLIB member.
To define a library console to MVS that allows console name message routing,
perform the following steps:
v Update PARMLIB member PARMLIB(CONSOLxx).
– Add console definitions for each library in your SCDS; an example follows:
CONSOLE DEVNUM(device number)
NAME(library console name)
UNIT(terminal type)
AUTH(SYS,IO)
(...)
– The library console name matches the console name defined in your SCDS
using the ISMF library definition panel.
The authorities (SYS and IO) are suggested in order to perform the modify
commands for OAM and the VARY commands for MVS.
See z/OS MVS System Commands and z/OS MVS Planning: Operations for further
information regarding multiple console support (MCS) definitions.
2dUpdate DEVSUPxx PARMLIB member.
Normally, when a scratch volume recorded in higher-level recording format is
mounted on a drive that that supports the media type but not the higher-level
recording format, the operating system rejects the mounted volume and asks for
another volume to be mounted. This is because the data set labels on the volume
cannot be read and validated. If you want the volume to be used, create a
DEVSUPxx member of PARMLIB and specify VOLNSNS=YES.
If you are partitioning an ATLDS, use the DEVSUPxx library partitioning-related
parameters to change the system default category assignments. See z/OS MVS
Initialization and Tuning Reference for more information regarding DEVSUPxx.
To take advantage of nonspecific (scratch) mount performance in a Virtual Tape
Server (VTS) or a Peer-to-Peer VTS, remember to set the Fast Ready attribute at the
library manager for the scratch categories to be used. This includes the system
default scratch categories and any user-defined scratch categories to be used for
partitioning the library.
For the capability to share MTL devices as stand-alone, see “Manual Tape Library
Considerations” on page 70 for potential usage of the MTLSHARE keyword.
3Update PROCLIB, by running CBRAPROC SAMPLIB member.
Sample jobs are provided in SAMPLIB to assist you in making the needed
additions to PROCLIB. Before running each SAMPLIB member:
v Update the JOB statement.
76
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
v Ensure that the high-level qualifier on the //OUT DD JCL statement matches the
naming standard at your installation.
Run SAMPLIB member CBRAPROC (see “SAMPLIB Member CBRAPROC” on
page 306) to create member OAM in PROCLIB. The following member is created
as the default:
//OAM PROC OSMC=YES,MAXS=2,UNLOAD=9999,EJECT=LRW,RESTART=YES
//IEFPROC EXEC PGM=CBROAM,REGION=0M,
// PARM=('OSMC=&OSMC,APLAN=CBROAM,MAXS=&MAXS,',
//
'UNLOAD=&UNLOAD,EJECT=&EJECT,RESTART=&RESTART')
//SYSABEND DD SYSOUT=A
Note: The default can be used because most of the parameters are only applicable
if OAM is used to store objects. For more information concerning the
RESTART parameter, see “Restarting OAM” on page 102. For information
concerning the other parameters associated with this procedure statement,
refer to z/OS DFSMS OAM Planning, Installation, and Storage Administration
Guide for Object Support.
Creating the Global Resource Serialization Environment
4Create the global resource serialization environment.
If you are going to share a tape library among two or more systems in an SMS
complex, the global resource serialization environment may be created to include
all sharing systems. This allows OAM to serialize the cartridge entry process for
more efficient operation. For general information about global resource
serialization, see z/OS MVS Planning: Global Resource Serialization.
The global resource serialization configuration is defined in member GRSCNFxx of
PARMLIB, which is described in the z/OS MVS Initialization and Tuning Guide. The
following resource names are obtained:
QNAME-SYSZCBR
RNAME-CARTRIDGE_ENTRY_libname
For export processing, the following resource names are used:
QNAME-SYSZCBR
RNAME-EXPORTED_CATEGORY_libname
For manual tape library processing, the following resource names are used:
QNAME-SYSZCBR
RNAME-MTL_VOLSER_volsername
For a further discussion of the resource names used by OAM during cartridge
entry processing, see “Using Global Resource Serialization with Cartridge Entry
Processing” on page 33. For further information regarding resource names used by
OAM during VTS export processing, see “Using Global Resource Serialization with
Export Processing” on page 41. For further information regarding resource names
used with manual tape library processing, see “Using Global Resource Serialization
in a Manual Tape Library” on page 33.
Note: OAM already performs a SYSTEMS level enqueue for global resource
serialization; therefore, there is no need to include the QNAME or RNAME
in the system inclusion RNL. The QNAME and RNAME are provided for
documentation purposes.
Chapter 3. Installing Your Tape Library Support
77
Creating the Tape Configuration Database
5Define the volume catalogs.
Use the AMS DEFINE command to define the general volume catalog
hlq.VOLCAT.VGENERAL. The general VOLCAT is the default volume catalog and
contains all of the library records as well as any volume records that do not reside
in a specific volume catalog. This volume catalog must exist before any tape library
can be defined.
If a large number of tape volumes have the same first character in the volume
serial number, it may be advisable to define specific volume catalogs
(hlq.VOLCAT.Vx), where x is the first character of the volume serial number.
Note: The letter V is reserved exclusively as the first character in a VOLCAT
volume serial number. It readily identifies the volume serial number as
belonging to a VOLCAT. To avoid confusion with the VOLCAT naming
conventions, the letter V is restricted from being used as the first character
of a tape library name. Any other character is valid.
See z/OS DFSMS Access Method Services for Catalogs manual for more information
on the DEFINE command and the z/OS DFSMS Managing Catalogs for more
information on estimating the size of the catalogs. Keep in mind that each virtual
tape server can contain thousands of volumes.
5aDefine general volume catalog.
The following example shows how to define the general volume catalog,
hlq.VOLCAT.VGENERAL.
//DEFVCAT JOB
...
//STEP1
EXEC PGM=IDCAMS
//SYSPRINT DD
SYSOUT=A
//SYSIN

The catalog parameters are:
NAME
Specifies the volume catalog,
hlq.VOLCAT.VGENERAL.
VOLCATALOG
Specifies that the user catalog is a volume catalog.
VOLUME
Specifies that the user catalog is to reside on
volume 338001.
CYLINDERS
Specifies that one cylinder is allocated to the
catalog and that when the catalog is extended, it
extends in increments of one cylinder.
All other parameters are allowed to default.
Note: The system uses “SYS1” as the default high-level qualifier (hlq). You may
choose any other high-level qualifier in its place. For more information on
changing the high-level qualifiers for VOLCATs, see z/OS DFSMS Managing
Catalogs.
78
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
5bDefine specific volume catalogs.
The following example shows how to define a specific volume catalog,
hlq.VOLCAT.VT. The catalog contains all the volume entries for tape volumes with
the first character of “T” in the volume serial number.
//DEFVCAT JOB

The catalog parameters are:
NAME
Specifies the volume catalog, hlq.VOLCAT.VT.
VOLCATALOG
Specifies that the user catalog is a volume catalog.
VOLUME
Specifies that the user catalog resides on volume
338001.
CYLINDERS
Specifies that one cylinder is allocated to the
catalog and that when the catalog is extended, it
extends in increments of one cylinder.
All other parameters are allowed to default.
Note: The system uses “SYS1” as the default high-level qualifier (hlq). You may
choose any other high-level qualifier in its place. For more information on
changing the high-level qualifiers for VOLCATs, see z/OS DFSMS Managing
Catalogs.
5cConnect the volume catalogs to the SMS complex.
Connect the volume catalogs to all other systems in the SMS complex that use the
tape library.
Use the AMS IMPORT command to connect the general volume catalog,
hlq.VOLCAT.VGENERAL and any specific volume catalog, hlq.VOLCAT.Vx.
The following function must be performed on each system in the SMS complex
except the one where the catalogs have been defined.
IMPORT CONNECT VOLCATALOG OBJECTS((hlq.VOLCAT.VGENERAL) operands)
IMPORT CONNECT VOLCATALOG OBJECTS((hlq.VOLCAT.Vx) operands)
5dDefine the RACF facility class profile.
Define the RACF facility class profile for access to the tape configuration database.
If you use RACF to protect your system resources, enter the following command
from an authorized TSO session:
RDEFINE FACILITY STGADMIN.IGG.LIBRARY options
5eAuthorize the storage administrator to the RACF facility class
Chapter 3. Installing Your Tape Library Support
79
The storage administrator TSO logon ID must be authorized for READ-level access
to the facility class. Enter the following command to authorize the storage
administrator for READ-level access.
PERMIT
STGADMIN.IGG.LIBRARY CLASS(FACILITY) ACCESS(READ) ID(logonID)
See z/OS Security Server RACF Command Language Reference for more information.
Creating the Hardware Configuration
6Define tape drives using HCD.
Use the MVS hardware configuration definition (HCD) to define the tape drives
that belong to the tape library. For an automated tape library device, specify the
LIBRARY parameter as YES. For a manual tape library device, specify the MTL
parameter as YES. The LIBRARY and MTL parameters are mutually exclusive.
Note: When defining the drives using HCD, device number 0000 is not supported
in an automated (which includes virtual) or manual tape library
environment.
The devices in an ATLDS are recognized as tape library devices as they are
initialized during IPL and during IODF activation. The devices in an MTL are
recognized as MTL devices only through the IODF definition.
When you define the tape drives in an ATLDS, you can optionally specify the
LIBRARY-ID and LIBPORT-ID parameters. If a tape drive is then busy or
unavailable at system IPL, the drive is configured based on the information
provided in the optional parameters and a subsequent IODF activate should not be
required. Without specification of the optional parameters, tape drives that are
busy or unavailable at system IPL are not included in the library control blocks
built by the system and are not eligible for allocation until the tape drives become
available and an IODF ACTIVATE is issued. When you define the tape drives in an
MTL, since the devices are not self-defining during IPL or IODF activation, the
LIBRARY-ID and LIBPORT-ID parameters must be specified. As with an ATLDS,
the LIBRARY-ID specified must match the LIBRARY-ID specified on the ISMF
define panel and can be any unique five-digit hexadecimal number. The
LIBPORT-ID identifies all devices attached to a specified control unit and should
start with subsystem “01”. Also, note that in the MTL environment, the maximum
number of subsystems supported is 32. For further information, see “IPLing the
System.” See z/OS HCD User's Guide for additional information about using the
HCD.
Note: For a Peer-to-Peer VTS Subsystem, the LIBRARY-ID specified should be the
composite library ID.
Because a library may contain emulated devices, successful communication to at
least one device in a subsystem must be made to determine if the devices defined
through HCD are real or emulated. If the communication cannot be made during
system IPL, the devices in the subsystem will not be considered eligible for
allocation until successful communication has been established with the MVS
VARY, ONLINE command. This will prevent the wrong device from being
considered in allocation recovery.
IPLing the System
7IPL the system.
80
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Use the new I/O configuration definition that contains the library tape drive
definitions to IPL the system. This also activates the OAM1 subsystem. The system
issues the following messages and you can use them to verify a successful IPL of
the system.
CBR8001I OAM1 subsystem initialization starting.
Note: If your installation is not using OAM to store objects, and is strictly using
OAM for tape library management, ignore the following messages when
they are displayed during IPL:
CBR8007I No DB2 SSID or the DB2 SSID value of “NONE” has been specified.
OTIS subsystem cannot successfully initialize.
CBR8002I OAM1 subsystem initialization completed.
Devices Unavailable at IPL: If message IEA438I is issued during system IPL
indicating that devices were not available during the IPL process (perhaps they
were in use on another system), perform the following steps:
1. Issue the MVS VARY command to vary the devices online.
2. Issue the ACTIVATE command to activate the IODF containing the devices that
were unavailable.
If your installation is using OAM for object support (DASD, optical, or tape), See
z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Object
Support for more information.
Creating the SMS Definitions
Creating Definitions with ISMF: ISMF provides a series of panels through which
SMS constructs can be defined. See z/OS DFSMS Using the Interactive Storage
Management Facility for detailed information about using ISMF. Use ISMF to:
v Define the base SCDS
v Define the libraries in the tape configuration database
v Define storage groups
v Define storage classes
v Define data classes
v Write and test ACS routines
v Validate the SCDS
Before proceeding with the following topics, study the relevant information
concerning creating the SMS definitions in Appendix B, “Using ISMF Panels to
Define and Monitor Your Configuration,” on page 327, and the z/OS DFSMSdfp
Storage Administration. This book, along with the online ISMF functional and help
panels, explains the items you specify using ISMF.
8Define the base SCDS.
The procedure for defining a source control data set is provided in z/OS DFSMSdfp
Storage Administration. It is possible to define several source control data sets
describing different configurations; however, only one SCDS can be activated at
any time.
9Define the tape libraries.
Chapter 3. Installing Your Tape Library Support
81
You need to define your tape library to add the library record to the TCDB and the
library definition to the specified SCDS. Choose option 3, DEFINE, on the ISMF
Tape Library Application Selection panel (Figure 37 on page 329) to display the
ISMF Tape Library Define panel shown in Figure 38 on page 330 and in Figure 40
on page 333. When defining the Peer-to-Peer VTS Subsystem, remember to define
not only the composite library but also the underlying distributed libraries.
10Define tape storage groups.
Use ISMF to define your tape storage groups and the library names associated
with the storage groups. For more information on how to define tape storage
groups, see z/OS DFSMSdfp Storage Administration and z/OS DFSMS Implementing
System-Managed Storage. To direct allocation to a Peer-to-Peer VTS Subsystem, the
composite library should be used and not the associated distributed libraries.
11Define storage classes.
Use ISMF to define storage classes that cause the installation storage group filter
routine to select tape storage groups. The storage class determines whether or not
a request is SMS-managed. If a storage class is not assigned, the request is not
SMS-managed.
12Define data classes.
Define data classes to direct your nonspecific requests to a specific media type and
recording technology, and to specify whether compaction is required. You may also
specify performance scaling, performance segmentation and encryption key label
information in your data class definitions. Choose option 4 on the ISMF Primary
Option Menu panel to display the ISMF Data Class Define panel to define your
data classes.
13Write and test ACS routines.
Create or modify the installation’s storage class, data class, and storage group ACS
routines to select tape constructs for certain types of new data requests. There can
be only one set of ACS routines in an active configuration. See z/OS DFSMSdfp
Storage Administration for information on using ISMF to define ACS routines.
Creating the Installation Exit Routines
14Create a cartridge entry installation exit routine—CBRUXENT.
If all cartridges entered into the library have the same use attribute and the same
tape device selection information (TDSI), these values can be assigned using the
entry default use attribute and the entry default data class on the library definition.
If cartridges are to have different use attributes, TDSI, or both, you need to write a
cartridge entry installation exit routine. You may use SYS1.SAMPLIB member
CBRSPUXE as a model. Otherwise, the system uses the installation exit provided
with DFSMSrmm. For detailed information on the installation exit, see “Cartridge
Entry Installation Exit (CBRUXENT)” on page 221.
15Create a change use attribute installation exit routine—CBRUXCUA.
If you need to influence the process of changing a volume’s use attribute (for
example, by preventing the return of a private volume to scratch), you need to
82
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
create an installation exit routine of your own. You may use SYS1.SAMPLIB
member CBRSPLCS as a model. Otherwise, the system uses the installation exit
provided with DFSMSrmm. For detailed information on the installation exit, see
“Change Use Attribute Installation Exit (CBRUXCUA)” on page 211.
16Create a cartridge eject installation exit routine—CBRUXEJC.
If you want to be able to prevent the ejection of a cartridge from the library or to
change the tape volume record for an ejected cartridge, you need to create an
installation exit of your own. You may use SYS1.SAMPLIB member CBRSPUXJ as a
model. Otherwise, the system uses the installation exit provided with DFSMSrmm.
For detailed information on the installation exit, see “Cartridge Eject Installation
Exit (CBRUXEJC)” on page 232.
17Create a volume not in library installation exit routine—CBRUXVNL.
If you want to be able to insert a volume into a tape library during job set up,
device allocation, or library mount processing to prevent job failures, you need to
create an installation exit routine of your own. You may use SYS1.SAMPLIB
member CBRSPUXV as a working model. Otherwise, the system uses the
installation exit provided with DFSMSrmm. For detailed information on the
installation exit, see “Volume Not in Library Installation Exit (CBRUXVNL)” on
page 240.
Note: Customer written installation exits are optional.
Validating the Configuration
18Validate the configuration.
You cannot use tape libraries until a configuration containing all the elements
described in this chapter are defined and validated. See z/OS DFSMSdfp Storage
Administration for information about validating the configuration that you have just
defined.
Activating the SMS Configuration
19Activate the SMS configuration.
Activate the SMS configuration that contains the library definitions. Only one
SCDS can be activated at any time. Activating another SCDS or reactivating the
current SCDS while OAM is running causes OAM to restart by default, unless
RESTART=NO is specified on the OAM PROCLIB member. During this
reinitialization, all libraries are set either online or offline according to the
attributes defined in the activated SCDS.
Note: How soon OAM is notified of the SCDS activation depends on the time
interval specified with the INTERVAL keyword in the IGDSMSxx PARMLIB
member.
Starting the OAM Address Space
20Start the OAM address space.
Start the OAM address space using the MVS START command. See “Starting
OAM” on page 100 for the syntax of the START command. Or the system
programmer can update the IGDSMSxx member of PARMLIB to start OAM
Chapter 3. Installing Your Tape Library Support
83
automatically during MVS IPL. “Changing System Libraries” on page 75 includes
information concerning updating the IGDSMSxx member of PARMLIB.
Note: The OAM address space must have been started on at least one of the
systems connected to each library to complete the definition of the library or
libraries in the TCDB. This completed information in the TCDB is needed to
properly run subsequent job streams.
Varying the Library Online
21Vary the library online.
Vary the library online using the SMS VARY command. See “Varying a Tape
Library Online or Offline” on page 101 for the syntax of the VARY command.
If the library was defined as online to the system, it is brought online as part of
OAM address space initialization.
Displaying and Setting the Cartridge Loader Media Type
22Display and set the cartridge loader media type.
22aDisplay the cartridge loader media type.
Use the MVS LIBRARY DISPCL or the LIBRARY DISPDRV command to display
the scratch volume media type assigned to the cartridge loader of each
library-resident tape drive. See “Displaying the Cartridge Loader Scratch Media
Type” on page 112 and “Displaying Tape Drive Status” on page 126 for the
command syntax.
22bSet the cartridge loader media type.
Use the MVS LIBRARY SETCL command to set the media type of scratch volumes
to be loaded into the cartridge loader of each library-resident tape drive. See
“Setting the Cartridge Loader Scratch Media Type” on page 113 for the command
syntax.
Running the Job Stream
23Run the job stream.
You can now run a job stream that uses library-resident volumes.
Outboard Policy Management Installation Recommendations
Before installing the outboard policy management support at the library, use the
following recommended steps to introduce this support. If a library with outboard
policy management support is shared by multiple systems, special consideration
should be taken as indicated in the steps below.
1 Define the SMS constructs to be used for outboard policy management and
their associated ACS routines. Activate the SCDS that contains the appropriate
changes. For example, to take advantage of physical volume pooling, you can
define additional storage groups to group logical volumes with common
characteristics on the same set of physical stacked volumes.
84
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
2 Install the full support PTFs (see OW54054) and coexistence support (see
OW54056), as appropriate, across all systems that will be sharing an outboard
policy management-enabled library.
Note: If all the systems have not installed the appropriate outboard policy
management support yet share both a common TCDB and an outboard
policy management-enabled library, the systems with full outboard policy
management support begin assigning the construct names as policy names
to the volumes in the outboard policy management-enabled libraries. This
assignment of construct names is normally a result of mount processing (or
another method such as entry processing or manual assignment).
However, when a system with no outboard policy management support or
with coexistence support mounts the volume (perhaps to write from load
point), the constructs that are assigned by the outboard policy management
supported system remain in effect. Also, a system with no outboard policy
management support does not clear the policy construct names when it
changes the use attribute to scratch. Therefore, previously assigned policies
and their associated actions are still in effect if the volume is subsequently
used from that system.
The following examples illustrate the assignment of a storage group policy based
on three separate scenarios:
Scenario 1: System with Full Outboard Policy Management Support
System A with full outboard policy management support assigns, through the ACS
routine, storage group SGBACKUP to volume VOL123 during mount processing
for file sequence 1. At the tape library, SGBACKUP is defined and associated with
physical stacked volumes belonging to POOL03. Logical volumes belonging to
SGBACKUP can then be segregated from logical volumes belonging to other
storage groups.
If System A changes the use attribute of VOL123 to scratch, the storage group
policy assignment at the library is changed to blanks, which is the default policy.
The next time VOL123 is used, a new storage group might be assigned through the
storage group ACS routine, and the actions that are defined to the new storage
group policy are performed. Also, if System A extends the data set on VOL123 to
another volume, the subsequent volume inherits the policies of VOL123.
Scenario 2: System with Coexistence Support
If System B with coexistence support uses VOL123 as a private volume to write
from load point immediately after System A's use, the volume is still assigned to
storage group SGBACKUP and the data is stored on physical stacked volumes that
belong to POOL03. If System B changes the use attribute of VOL123 to scratch, the
storage group policy assignment at the library changes to blanks, which is the
default policy. Subsequent use of VOL123 by System B, assuming that there is no
involvement of System A, continues to use default policy actions. No new policy
assignment occurs.
Also, if System B extends the data set on VOL123 to another volume, the
subsequent volume inherits the policies of VOL123.
Scenario 3: System with No Support Installed (Full or Coexistence)
Chapter 3. Installing Your Tape Library Support
85
If System C with no outboard policy management support uses VOL123 as a
private volume to write from load point immediately after System A's use, the
volume is still assigned SGBACKUP and the data is stored on physical stacked
volumes belonging to POOL03. If System C changes the use attribute of VOL123 to
scratch, the SGBACKUP policy attribute remains assigned to VOL123. Subsequent
use of VOL123 by System C, with no System A or System B involvement,
continues to use SGBACKUP storage group policy actions at the library, which is
no longer appropriate for the data that is written on the volume. If System C
extends the data set on VOL123 to another volume, the subsequent volume does
not inherit the policies of VOL123, which results in policy inconsistencies at the
library for the volumes of the multivolume data set.
To prevent the systems from improperly using the policies, install the software
across all sharing systems before installing the outboard policy management
support in the library. Coexistence support is available for DFSMS/MVS V1R5
systems.
If policy name corrections are needed due to a mix of support on the systems, you
can change a volume's policy names by using the LCS External Services general
programming interface FUNC=CUA or by using the LIBRARY LMPOLICY
operator command. However, policy actions based on the policy name changes
might not take effect until after the volume is subsequently mounted. Manually
changing the policy names does not mean that the actions of the policy are acted
upon immediately.
3 As appropriate for your tape management system, update the change use
attribute installation exit (CBRUXCUA) and the cartridge entry installation exit
(CBRUXENT) with the outboard policy management support capabilities. Link-edit
the new version of these exits on the applicable outboard policy management
coexistence or full support systems.
4 Install the outboard policy management microcode enhancement and then
define policy actions at the library:
v Vary the VTS library offline at the host before installing the outboard policy
management support. Otherwise, job processing or entry processing might start
to assign policies before implementation setup is complete. A stand-alone VTS
must be varied offline to install the new level of microcode. However, a PtP VTS
can remain online to the host with the microcode installed while the libraries are
in service preparation mode.
v After the outboard policy management support has been installed at the library,
define the SMS constructs “policy names” that will be assigned through the ACS
routines and their associated actions. If a policy name is not created at the
library, the policy names are automatically created, but given default actions at
the library.
Note: If outboard policy management support is installed before installing the
software PTFs, define default policy actions for all new policies so that the
library performs as if no outboard policy management support has been
installed or continue to use the default policy names (blanks) and actions
that are automatically set up by the library. Once all of the appropriate
software has been installed, nondefault policy names and actions can be
defined at the library.
v Vary the library online at the host.
86
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
5 Allow normal job processing to assign policies to volumes, gradually
implementing the outboard policy management functions. All existing volumes are
initially assigned default policy names (blanks) when the outboard policy
management is first installed. Default policies have actions that are equivalent to a
library without outboard policy management support. Therefore, a library with all
default policies functions like a library with no outboard policy management
support installed.
Outboard Policy Management Test Environments
The ideal test environment is for the outboard policy management-enabled library
to be attached exclusively to the test system, which allows the test environment to
use the same construct names as the production systems.
Recommendation: If the production and test systems share an outboard policy
management-enabled library, each test system can have a separate TCDB and a
separate SCDS with construct names different from those that are used by the
production system. This setup allows the system to experiment with the outboard
policy management function without effecting the production system's volumes.
Outboard Policy Management Migration and Expected Actions
When policy names and their associated actions are not predefined at the library,
the first time that they are assigned to a volume, the library creates the policy
name and assigns default actions.
Storage Group Policy: If the storage group construct is not predefined at the
library and the policy is automatically created with default actions, the logical
volume that is written is stored on a physical stacked volume from the common
scratch pool. If the construct definition is altered to specify a physical pool, the
data is not moved to the pool that is specified until after the volume is next
mounted.
Storage Class Policy: If you are currently using the storage class Initial Access
Response Time (IART) to set cache residency in the VTS, the volume's assigned
storage class construct action overrides the value set by the storage class IART.
However, if the storage class construct has not been predefined to the library but
was created automatically when the host sent the construct to the library, the
policy's cache residency action by default allows the IART value to take
precedence. You can explicitly define the storage class policy at the library to allow
the host's IART specification to take precedence or to allow the outboard policy
action to take precedence. If there is no IART value being passed to the library and
the policy construct does not have a cache preference set, the default preference
level of 1 is used.
Management Class Policy: If the management class construct is not predefined at
the library and the policy is automatically created with default actions, the
selective dual copy function is not performed for a volume because the default
action does not create a second copy in the VTS for the volume. If the policy
definition is updated to make a second copy of the volume, the second copy is not
created retroactively. The action of creating the second copy occurs after the
volume is subsequently mounted.
If the management class policy name is not predefined at the PtP VTS library and
the policy is automatically created with default actions, the Selective PtP Copy
Mode action uses the current library mode control settings as a default. If the
Chapter 3. Installing Your Tape Library Support
87
management class policy PtP Copy Mode is updated, the management class policy
copy setting overrides the current library mode control setting when the volume is
next written.
In addition to the outboard policy management actions identified above, additional
policy actions may be implemented at the library. For a complete discussion of the
outboard policy actions see IBM TotalStorage Enterprise Automated Tape Library (3494)
Operator’s Guide.
Tape Subsystem (Device Pool) Limitation
With the system-managed tape library support, each scratch allocation (through the
ACS routines) will assign one or more tape storage groups and each tape storage
group can be associated with 1-8 tape libraries. As a result of this there can be
many tape subsystems (and devices) that are considered eligible for each scratch
request. A limitation exists today on the number of tape subsystems (device pools)
that SMS and MVS allocation can support with a scratch allocation. Today this
limit is 253 tape subsystems or 4048 devices (253 x 16 devices). With APAR
OA21462, SMS will detect and limit the number of eligible tape subsystems (device
pools) to the first 253 subsystems and will ignore the tape subsystems beyond 253.
For example, if an installation is using the TS7700 Virtualization Engine and
assigns SGTAPE and SGTAPE associated with 4 two-cluster grids, the maximum
number of tape subsystems that could be returned to SMS would be 4 X (32
subsystems each) = 128 which is well within the existing 253 subsystem limit.
However, if an installation, for example were using 6 three-cluster grids, and
SGTAPE was associated with all 6 three-cluster grids, the maximum number of
tape subsystems that could be returned to SMS would be 6 X (48 subsystems each)
= 288 which would go over the existing subsystem limit of 253. If there are more
than 253 tape subsystems considered eligible for the scratch request, SMS will only
return the first 253 tape subsystems to MVS allocation. As you start using libraries
with more and more tape subsystems (for example, the TS7700 Virtualization
Engine), review your ACS routines and the number of tape libraries, and
subsystems, being used for your scratch allocations.
Library Subsystem Modifications
This section discusses the steps that are necessary when tape subsystems are
added, moved or deleted. A cable change within a library that switches ports so
that existing subsystems are now associated with different subsystem IDs should
be treated as if the subsystems had been physically moved.
For an existing library, before modifying the subsystem configuration, use the
VARY SMS command to VARY the library offline to each attached host. After the
necessary IODF ACTIVATEs or optional IPL, use the LIBRARY DISPDRV
command to verify that the correct number of devices appear in the library
configuration and that no device appears multiple times in the display for that
library.
Adding Subsystems to a Library
The simplest way to add new subsystems to a new or existing library is to add
previously undefined library devices to the physical end of the library. This keeps
the existing subsystems associated with the same subsystem IDs and the new
subsystems associated with the next sequential subsystem IDs. To add subsystems
to a new or existing library, perform the following steps:
88
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
1. Use the MVS hardware configuration definition (HCD) to add the new tape
devices to the existing or a new IODF.
2. Activate the IODF containing the new tape devices by activating from the ISPF
HCD panels, or by entering the MVS ACTIVATE command on the z/OS
console.
3. Vary the devices online to MVS using the MVS VARY command.
4. Once again, activate the IODF containing the new tape devices to complete the
configuration activity by activating from the ISPF HCD panels, or by entering
the MVS ACTIVATE command on the z/OS console..
Note: Steps 1–4 can be replaced with a system IPL using the IODF that was
created in step 1.
If one or more of the subsystems being added to the physical end of the library
(library A) had previously existed in another library (library B), perform the
following steps:
1. Use the MVS hardware configuration definition (HCD) to delete all devices
from library B.
2. Activate the IODF that has the devices from library B removed by activating
from the ISPF HCD panels, or by entering the MVS ACTIVATE command on
the z/OS console.
3. Use HCD to add all of the devices that are now in library A and in library B.
4. Activate the IODF that has all the devices defined by activating from the ISPF
HCD panels, or by entering the MVS ACTIVATE command on the z/OS
console.
5. Vary the devices online to MVS using the MVS VARY command.
6. Once again, activate the IODF containing all of the tape devices to complete the
configuration activity by activating from the ISPF HCD panels, or by entering
the MVS ACTIVATE command on the z/OS console.
Note: Steps 1–6 can be replaced with a system IPL using an IODF containing
all of the moved or new devices, or both.
If the subsystems being added are not added to the physical end of the library, see
“Moving Subsystems within a Library.”
Moving Subsystems within a Library
If existing subsystems are physically moved within a library so that the subsystems
are now associated with different subsystem numbers (for example, if the new
subsystems are not added to the physical end of the library), perform the following
steps to properly rebuild the new configuration:
1. Use HCD to delete all devices form the library or libraries involved (multiple
libraries might be involved if the devices came from another library).
2. Activate the IODF that has all the devices from the libraries removed by
activating from the ISPF HCD panels, or by entering the MVS ACTIVATE
command on the z/OS console.
3. Use HCD to add all of the devices that are now in each affected library.
4. Activate the IODF that has all the devices defined by activating from the ISPF
HCD panels, or by entering the MVS ACTIVATE command on the z/OS
console.
5. Vary the devices online to MVS using the MVS VARY command.
Chapter 3. Installing Your Tape Library Support
89
6. Once again, activate the IODF containing all the tape devices to complete the
configuration activity by activating from the ISPF HCD panels, or by entering
the MVS ACTIVATE command on the z/OS console..
Note: Steps 1–6 can be replaced with a system IPL using the IODF containing
all of the library devices.
Deleting Subsystems from a Library
If existing subsystems are physically removed from a library, then perform the
following steps to accurately reflect the new configuration:
1. Use HCD to delete all devices from the library.
2. Activate the IODF that has the devices from the library removed by activating
from the ISPF HCD panels, or by entering the MVS ACTIVATE command on
the z/OS console.
3. Use HCD to add all of the devices that are now in the library.
4. Activate the IODF that has all the devices defined by activating from the ISPF
HCD panels, or by entering the MVS ACTIVATE command on the z/OS
console.
5. Vary the devices online to MVS using the MVS VARY command.
6. Once again, activate the IODF containing all of the tape devices to complete the
configuration activity by activating from the ISPF HCD panels, or by entering
the MVS ACTIVATE command on the z/OS console.
Note: Steps 1–6 can be replaced with a system IPL using an IODF that has the
deleted devices removed.
If the deleted subsystems are then added to another library, follow the
steps documented in “Adding Subsystems to a Library” on page 88.
The sections above assume that as subsystems are added, moved, or deleted,
previously existing subsystems may now be associated with different subsystem
IDs. The sections above also document the steps necessary regardless of whether
the subsystem IDs at the library manager have changed.
If the steps documented in the sections above are not followed, you may have the
same device being configured in multiple device pools or the appearance of more
drives then are actually in the library, or both, resulting in subsequent failures
during library processing.

z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Chapter 4. Defining and Monitoring Your Configuration
Thischapter discusses typical administration tasks for defining and monitoring the
SMS configuration associated with your tape library:
v Monitoring and maintaining the tape configuration
v Monitoring and maintaining SMS constructs and definitions
v Establishing recovery procedures
v Retrieving data from a disabled IBM automated tape library
Monitoring and Maintaining the Tape Configuration
ISMF makes it possible to monitor and maintain information associated with the
tape configuration database, the source control data set, and the tape volumes that
reside in automated and manual tape libraries.
Typical Library Management Functions
The ISMF Library Management option allows you to generate lists of tape libraries
and volumes, display the attributes of a tape library, alter definitions that were
originally defined, add new definitions, audit tape libraries and tape volumes, and
eject tape volumes from the tape library.
This section discusses the effects of some typical configuration maintenance tasks.
See Appendix B, “Using ISMF Panels to Define and Monitor Your Configuration,”
on page 327 for information concerning the use of ISMF with tape libraries, and
see z/OS DFSMS Using the Interactive Storage Management Facility for detailed
information about using ISMF.
Defining Tape Libraries
The first time a tape library is defined, the storage administrator enters all the
appropriate attribute definitions associated with the tape library being defined on
the ISMF define panels. Once all the information is entered, an entry containing
that information is added to the tape configuration database (TCDB). Also, a tape
library definition is added to the specified source control data set (SCDS). For more
detail concerning defining tape libraries using ISMF, see “Defining a Tape Library”
on page 327.
When you attempt changes to the attribute definitions of an existing tape library,
the information residing in the TCDB associated with the tape library is displayed
through a Redefine panel. Changing any of the attributes previously defined
results in an update to the TCDB and to the specified SCDS. For more information
on redefining tape libraries, see “Redefining a Tape Library” on page 340.
Note: Only one SCDS can be activated at any time. Activating another SCDS or
reactivating the current SCDS while OAM is running causes OAM to restart
by default, unless RESTART=NO is specified in the OAM PROCLIB
member. During this restart, all libraries are set to either online or offline
according to the attributes defined in the SCDS. After the restart completes,
display all libraries to verify that they are set to the desired operational
state.

91
Altering the Tape Library Definition
Altering a tape library definition results in an update to the corresponding library
record in the TCDB and the SCDS. For more information on altering a tape library,
see “Altering a Tape Library” on page 342.
Note: The altered library definition takes effect when the SCDS is activated and
OAM is restarted.
Managing the Tape Volume
The ISMF Library Management function also assists in the maintenance and
verification of the tape volumes within the tape library dataservers through the use
of the Mountable Tape Volume Application available from the Tape Library
Application Selection panel (option 1—LIST).
Note: If the TCDB is being shared across multiple system levels, volume records
containing TDSI information that are not understood by the level of
software on the system are not displayed when a volume list is requested
from ISMF. This prevents the system from processing volume records
containing TDSI information that is not understood by the system.
Using the Mountable Tape Volume Application, storage administrators can use line
operators or ISMF commands to perform inventory tasks against tape libraries and
tape volumes. The following functions can be performed using the Mountable Tape
Volume Application:
v AUDIT a volume, a list of volumes, or a tape library
Note: The audit functions are not supported in an MTL.
v ALTER the use attribute, storage group, shelf location, or owner information of
a volume or list of volumes
v EJECT a single tape volume
For more detail on the use of the Mountable Tape Volume Application, see “ISMF
Mountable Tape Volume Application” on page 348.
Auditing the Tape Library Volume in an ATLDS
The AUDIT function in an ATLDS helps you verify the physical location of tape
volumes within the library. It verifies whether or not a library volume resides in
the location listed for that volume in the library manager inventory. The volume
records in the TCDB identify the libraries where the volumes reside. If the TCDB
records do not match the library manager inventory when an audit is performed,
the TCDB records, the inventory, or both, must be corrected. The AUDIT function
does not perform any corrective actions; messages are issued and the volume error
status field in each tape volume record is updated, but the purpose of the audit is
verification only. For more information concerning auditing tape volumes with
ISMF, see “Auditing Volumes in an Automated Tape Library” on page 359.
Note: In an environment with multiple systems at different software levels but
sharing a common TCDB, library audits should be performed on the system
with the highest software level. A library audit on a lower software level
does not include higher release level volumes if there are media types
unknown to the lower level software.
Altering the Tape Volume Record
ISMF allows you to alter the use attribute, storage group, shelf location, and owner
information of a single tape volume or a list of tape volumes through the use of
92
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
the ALTER line operator or the ISMF ALTER command. These commands are used
from the Mountable Tape Volume List panel (see Figure 60 on page 351). For more
detail regarding the ISMF alter commands, see “Altering the Volume Record” on
page 362.
Ejecting the Tape Volume With the EJECT Line Operator
The EJECT line operator is used to eject a single library-resident volume from a
tape library with the option of keeping or purging the associated tape volume
record within the TCDB. The EJECT line operator command is used from the
Mountable Tape Volume List application of ISMF. For more information concerning
this line operator and the Mountable Tape Volume List, see “Ejecting a Volume
from a Tape Library” on page 367 and Figure 60 on page 351.
Monitoring and Maintaining SMS Library Definitions
ISMF library management makes it possible to monitor and make changes to the
SMS library definitions. See z/OS DFSMS Using the Interactive Storage Management
Facility for detailed information about using ISMF.
Changing z/OS Construct Definitions
As installation requirements change, it may be necessary to update data class,
storage group, management class, and storage class definitions in your ACS
routines. Definitions for these constructs can be modified using the ISMF ALTER
panels.
These updates must be done with caution because volumes that do not require
processing after the definitions are changed are not affected by the change, even
though they are assigned to the group to which the new definition applies. The
updated definitions are used only for volumes entering the system or processed by
the system after the change.
Outboard Policy Management Definitions
If the library is also enabled for outboard policy management, the construct’s
policy also needs to be defined outboard at the library with appropriate policy
actions, unless default actions are to be used at the library. If the construct’s policy
does not exist, the library creates the policy name and uses default actions.
Maintaining Tape Storage Group Definitions
New storage groups may be needed for separation of new types of volumes. In
addition to defining the new tape storage groups, it is necessary to modify the
ACS routines to use the new tape storage groups.
It is important to consider when you are designing these changes that existing
volumes do not change their storage group assignments until they are changed to
scratch and then back to private, or until they are manually changed either
through ISMF volume ALTER, the CBRXLCS FUNC=CUA interface, or the
LIBRARY LMPOLICY command. If a private volume is assigned to a new storage
group through the storage group ACS routine, the storage group remains as it was
set in the tape configuration database.
Changing ACS Routines
As mentioned above, ACS routines may need to be changed to support changes in
storage group, data class, management class, or storage class definitions. Defining
Chapter 4. Defining and Monitoring Your Configuration
93
new storage groups, data classes, management classes, or storage classes has no
affect unless the ACS routines are changed to select those new constructs.
ACS routines can be changed to provide initial class defaults for new volumes.
Defining new classes does not always mean new values for parameters; a new
class can have the same parameters as an existing class. A new class may be
created to make the relationship between a class and an application more
understandable. This action makes it possible to modify parameters later to fit the
needs of one application without affecting other applications.
A Final Note of Caution about Changing SMS Library Definitions: Changing
existing library definitions may not affect all volumes associated with those
definitions. Only those being stored after the library definitions have been changed
are affected.
Establishing Recovery Procedures
As part of your disaster recovery plan, you should establish and test procedures
for recovering the following entities:
v Tape configuration database
v Library entries in the volume catalog
v Volume entries in the volume catalog
Recovering Volume Catalogs
OAM attempts to keep volume catalog entries current. This cannot be
accomplished if the catalog entry does not exist or if the catalog is unusable (for
example, because of I/O errors). Recovery of the catalog may be required.
Standard catalog recovery procedures apply to recovering volume catalogs. Those
procedures usually involve making an image copy (for example, IDCAMS
EXPORT) at certain intervals and restoring that copy (for example, IDCAMS
IMPORT) to recover an unusable catalog, then applying changes to individual
records based on some ICF transaction log (for example, SMF records).
Note: For further information on the use of IDCAMS with catalog entries, see z/OS
DFSMS Access Method Services for Catalogs.
Recreating Library Entries
If library entries are added or deleted after the image copy is made, restoring an
image copy does not complete the recovery; you must also recreate those added or
deleted entries. Use IDCAMS CREATE or IDCAMS DELETE to create or to delete
the library entries.
If library entries are modified after the image copy is made, use IDCAMS ALTER
to update the library entry to its current state.
Note: Attempt this level of recovery only if the transaction log recovery cannot be
used. For further information on the use of IDCAMS with library entries,
see z/OS DFSMS Access Method Services for Catalogs.
Recreating Volume Entries
If volume entries are added or deleted after the image copy is made, restoring an
image copy does not complete the recovery; you must also recreate those added or
deleted entries. Use IDCAMS CREATE or IDCAMS DELETE to create or to delete
the volume entries.
94
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
If volume entries are modified after the image copy is made, use IDCAMS ALTER
to update the volume entry to its current state.
Note: Attempt this level of recovery only if the transaction log recovery cannot be
used. For further information on the use of IDCAMS with volume entries,
see z/OS DFSMS Access Method Services for Catalogs.
Disaster Recovery Site Considerations
If you plan to run your disaster recovery test on a system where there is no tape
library, then you must EXPORT DISCONNECT the TCDB from that remote system
so that normal stand-alone drive allocation paths are used by SMS and MVS
allocation. Your ACS routines should also be reviewed and changed, if necessary,
to ensure that they are not assigning a tape storage group that forces the allocation
to a tape library.
Typically this processing does not require the OAM address space to be started;
however, if you are also using OAM object support and need to start the OAM
address space, considerations must be given to any tape library definitions that are
in the SCDS. Before starting the OAM address space, any tape library definitions
associated with the remote system that have an "Initial Online Status" of "YES" or
"NO", need to have the initial online status set to blank to indicate that the library
is not connected to that system. This enables the OAM address space to bypass
those tape library definitions during OAM initialization. However, for that update
to be successful, the TCDB needs to be connected. Once the updates have been
made, the TCDB can be disconnected and the updated SCDS can be activated.
Note: For further information on the use of IDCAMS EXPORT of VOLCAT, see
z/OS DFSMS Access Method Services for Catalogs.
TCDB Procedure for Retrieving Data from a Disabled IBM Automated
Tape Library
There may be a time when you might experience a problem that could disable
your IBM automated tape library. The following procedure provides instructions
for retrieving data from an IBM automated tape library after a serious library
manager failure occurs with the PC controller. By following this procedure, you
can allocate your library volumes to stand-alone devices to retrieve your data after
a few modifications to the TCDB and possibly the job stream. This procedure is
only a short-term solution and should only be used if there is an immediate need
for the data in the disabled IBM automated tape library.
Altering Private Tape Configuration Database Records
Alter the TCDB for each private volume serial number from the disabled library
that you plan to use. Use IDCAMS or a utility from your tape management system
that invokes the IDCAMS facility. The LOCATION field in the TCDB must be
altered from LIBRARY to SHELF. When altering the LOCATION field, IDCAMS
also modifies the LIBRARYNAME field to SHELF. This field value change allows
the private volume serial numbers to be used outside the library for
non-SMS-managed requests. After the library manager is back online, and the
volumes are returned to their home cells, the LOCATION and LIBRARYNAME
fields in the TCDB must be altered. The LOCATION field must be altered back to
LIBRARY and the LIBRARYNAME field must be altered to reflect the library name
where the volumes reside.

//ALTERVOL JOB 'NAME',MSGCLASS=H,MSGLEVEL=(1,1),CLASS=A

//ALTER EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
ALTER VOAM100VOLUMEENTRYLOCATION(LIBRARY)LIBRARYNAME(ATLF4007)
/*
//
Changing from SMS-Managed to Non-SMS-Managed Requests
JCL jobs and applications that refer to scratch requests or to altered shelf-resident
private volumes using DISP=NEW can be changed from SMS-managed to
non-SMS-managed requests in one of two ways:
1. Modify the JCL or application associated PARMLIB member so that the
requests are treated as non-SMS-managed requests.
2. Activate a new SCDS that treats the existing JCL and applications with no
modifications as non-SMS-managed requests.
By changing to a non-SMS-managed request in the ACS routine, MVS allocation
selects a non-SMS-managed device during the allocation process. Examine the
constructs and the criteria used in the ACS routines to determine what requests
need to be changed to non-SMS-managed.
Note: If storage groups selected from the ACS routine span multiple libraries,
scratch allocations are automatically directed to the other libraries.
Changing the Use Attribute of Scratch Volumes
If you are using scratch volumes from the disabled library, then after the disabled
library is back online either:
1. Use ISMF to alter the use attribute and the storage group, or
2. Code a CBRXLCS CUA invocation to change the use attribute from S to P and
the appropriate storage group from *SCRTCH*
Either of these procedures must be done before any scratch requests are submitted.
If one of them is not performed, then previously written data may be overwritten
on the next scratch request to that library since the scratch volumes used still exist
in a scratch category in the library manager inventory.
96
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
If you are using scratch volumes outside the disabled library, then after the
disabled library is back online, enter those newly written volumes into the library
and assign a use attribute of P and a storage group to preserve the data written on
the volumes.
JCL jobs and applications that are referencing existing data on the altered private
volumes with DISP=OLD or DISP=MOD may not require any changes. In this case,
the ACS routines are not invoked and a device gets allocated based solely on the
specified UNIT parameter indicated in the JCL or associated with the application
program.
Note: If you have OAM Object Tape support and have altered the SETOAM
parameters in the CBROAMxx PARMLIB member, you must restart the
OAM address space in order for these changes to take effect.
Using the Sample Exit for Volume Not In Library (CBRUXVNL)
After submitting the jobs and applications for the altered private volume serial
numbers, the operator replies to a message from the CBRUXVNL exit. The
operator either replies CONT to continue the request to a stand-alone device, or
DISABLE to deactivate the volume not in library exit for future replies. By
disabling the CBRUXVNL exit, the requests for the altered volume serial numbers
are allocated to stand-alone devices, but for SMS-managed requests for volumes
that reside on the shelf, the jobs fail. The CBRUXVNL exit can be re-enabled by
using the OAM LIBRARY RESET,CBRUXVNL command.
Library Manager Database Volume List
It is important to maintain a volume list that has the current home cell locations
for your ATLDS library volumes. This volume list can be obtained from the library
manager console by selecting DATABASE from the main menu pull-down window
and then selecting a function called LIST DATABASE VOLUMES. This function
generates a volume list that has the current home cell locations. This list can be
saved on a diskette and referenced or printed with any remote PC ASCII editor. If
you configured your Home Cell Mode to FLOAT, this operation will have to be
run more often than if this mode was configured to FIXED. Floating home cells can
change after volumes are demounted from the library devices. Maintaining these
cell locations prevents the operator from manually searching for volumes in the
disabled library.
Returning the Library Manager to an Operational Status
After the tape library is returned to an operational state, restore your modified
JCL, PARMLIB members, and the TCDB records to their original values. Use the
SMS library VARY command to vary the tape library online and then reactivate the
original SCDS. After OAM has restarted, run an OAM library audit command to
ensure that the volumes are returned to their correct home cell locations before
allocating to that library.

Chapter 5. Operating the OAM Address Space
This chapter helps you become familiar with operator commands and describes the
common tasks needed to operate the OAM address space.
Overview of Operator Tasks
You can perform the following operator tasks:
v Start OAM
v Restart OAM
v Vary:
– Tape library online and offline
– Tape drive online and offline
v Eject a specific tape volume
v Audit a tape volume
v Enter a volume into a manual tape library
v Import volumes into a virtual tape server library
v Export volumes from a virtual tape server library
v Request Information from the TS7700 Virtualization Engine
v Disable Cartridge Entry Installation Exit processing
Disable Volume Not in Library Installation Exit processing
Re-enable installation exit processing
Display the cartridge loader scratch media type for a tape drive
Set the cartridge loader scratch media type for a tape drive or a range of tape
drives
v Assign library manager policy names outboard (for libraries that support
outboard policy management)
v
v
v
v
v Display the status of:
– OAM
– Tape library
– Tape drive
– Tape storage group
– Tape volume
– Outstanding OAM messages
v Stop OAM
v Capture Data for Diagnostic Purposes (OAM DUMP)
v Query OAM active and pending tape library requests (OAM QUERY)
v Query device services library information (DEVSERV QLIB)
Note: You may have an environment with multiple systems at different levels
sharing a common TCDB. In this event, if a system attempts to perform an
operator command against a volume that has a media type or recording
technology that is not recognized, the request fails.

Specify shelf location for volume volser.
Note: In message text, italicized words indicate a value supplied by the system.
Starting OAM
Use the MVS START command to start the OAM address space manually or to
restart the OAM address space after it has terminated. The syntax of the MVS
START command that is used to start OAM follows:
START
S
OAM
procname
.identifier
OAM
Name of the IBM-supplied cataloged procedure that invokes OAM.
procname
Name of the user-written cataloged procedure that invokes OAM.
.identifier
User-determined name that identifies the OAM address space. If
you do not specify an identifier, the system automatically uses the
procname as the identifier.
Related Reading: For further information on the MVS START command and
additional parameters that can be specified, see z/OS MVS System Commands.
When OAM is initialized, the system issues the following messages:
100
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
CBR0001I
OAM initialization starting.
CBR0002I
OAM initialization completed.
If other CBRxxxxx messages are issued, see z/OS MVS System Messages, Vol 4
(CBD-DMO) for the appropriate action to take.
Varying a Tape Library Online or Offline
Use the VARY SMS command to vary libraries online or vary them offline. The
syntax of the command to vary the libraries follows:
VARY
V
SMS,
LIBRARY
LIB
(library_name
),
,
*
ALL
(1)
system_id
*
ONLINE
ON
OFFLINE
OFF
Notes:
1
You can specify up to eight system_ids (each must be separated by a
comma).
OAM does not set the library offline until all the tape drives in the library are set
offline. Such drives are considered offline for library reasons. When an individual
drive is marked offline as a result of the VARY ddd,OFFLINE command, it is
considered offline for operator reasons. Each offline state must be separately reset
before the drive is again online. A VARY SMS,LIB command does not bring a
drive online if the drive is currently offline for operator reasons. A VARY
ddd,ONLINE command does not bring a drive online if the drive is currently
offline for library reasons.
Note: A composite and distributed VTS library can be varied online and offline
like any VTS library, though varying a distributed library offline from the
host really has no meaning (does not prevent outboard usage of the library).
Message CBR3016I warns the user when a distributed library is initialized or
varied offline.
LIBRARY | LIB(library_name)
Specifies the name of the library to be varied online or offline. If
the name is not specified or the specified library is not defined in
the SMS configuration, an error message is displayed.
ALL
Varies the state of the tape library on all systems in the SMS
complex to which the library is connected.
*
Varies the state of the tape library only on the system or system
group from which the VARY command is issued. If the system or
Chapter 5. Operating the OAM Address Space
101
system group on which the VARY command is issued is not
connected to the named library, an error message is displayed. This
is the default.
system_id
Varies the state of the tape library only on the systems or system
groups that are specified. If a specified system is not connected to
the named tape library, an error message is displayed.
Note: To specify a system or system group that is named ALL,
surround it with parentheses; for example, VARY
SMS,LIBRARY(library_name,(ALL)),ONLINE.
ONLINE | ON
Specifies that the library be varied online.
OFFLINE | OFF
Specifies that the library be varied offline.
An example of the command to vary a tape library online:
VARY SMS,LIBRARY(ATL01),ONLINE
An example of the command to vary a tape library offline:
VARY SMS,LIBRARY(ATL01),OFFLINE
Restarting OAM
OAM provides the ability for you to specify a RESTART option on the OAM
started procedure statement (see the example in 77 under Run SAMPLIB member
CBRAPROC). This option indicates that OAM should or should not be restarted
upon notification that a new SCDS has been activated. A new or changed SCDS
does not always affect the configuration information that OAM uses; therefore, a
restart of the OAM address space may not always be necessary each time a new or
changed SCDS is activated. This option provides a choice to the customer to decide
on the most efficient use of their OAM resources.
If you specify RESTART=YES (the default), OAM restarts automatically once it is
notified that an SCDS activation has occurred. OAM completes work that is
currently on its execution queues, requeues any work from outside the OAM
address space to the input work queue, and terminates any work from within the
OAM address space not currently executing. OAM rebuilds its internal control
blocks to match the SMS definitions in the recently activated SCDS. When OAM is
back to full capacity (restart complete), the work requeued to the input work
queue begins processing.
Note: How soon OAM is notified of the SCDS activation depends on the time
interval that you specify with the INTERVAL keyword in the IGDSMSxx
PARMLIB member.
If you specify RESTART=NO, OAM continues processing without rebuilding its
internal control blocks when it is notified that an SCDS activation has occurred.

restart may be required.
OAM address space
It is the responsibility of the installation to ensure that the OAM RESTART
command is issued if an OAM address space restart is necessary.
The OAM RESTART command causes OAM to restart the OAM address space.
During restart processing, OAM matches the constructs and definitions to those
that are found in the active SMS configuration.
By using this command, you can avoid having to perform STOP and START
commands of the OAM address space. This command allows the OAM address
space to retain its current ASID.
To restart the OAM address space without first stopping OAM, enter the following
RESTART command:
MODIFY
F
OAM ,
RESTART
Varying Tape Drives Online or Offline
Use the MVS VARY command to vary tape drives online or offline. See z/OS MVS
System Commands for additional information on the MVS VARY command.
Ejecting a Specific Tape Volume
Use the MVS LIBRARY EJECT command to eject a specific tape volume from a
tape library. When this command is issued for an ATLDS, the tape volume is
placed into an output station of the tape library. For an MTL, no physical
movement takes place as a result of this command.
The syntax of the command to eject a specific tape volume is:
LIBRARY
LI
EJECT | E
EJECT
E
,volser
,
PURGE
P
KEEP
K
LOCATION
L
,
BULK
B
Specifies a request to eject a specific tape volume from a tape
library.
Chapter 5. Operating the OAM Address Space
103
volser
Specifies the volume serial number of the tape volume that is
ejected from the tape library.
{PURGE | P | KEEP | K | LOCATION | L}
Specifies the disposition of the volume record in the TCDB when a
tape cartridge is ejected from the library. If neither PURGE nor
KEEP is specified, then the disposition of the volume record in the
TCDB is determined by the eject default that is entered on the
ISMF Tape Library Define panel.
104
PURGE | P
Specifies that the volume record in the TCDB be
deleted upon completion of the EJECT operation.
KEEP | K
Specifies that the volume record in the TCDB be
retained upon completion of the EJECT operation.
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
LOCATION | L
Specifies that you want to update the shelf location
associated with the tape volume. When
LOCATION is specified, a write-to-operator-withreplay (WTOR) message is issued to the MVS
operator prompting for 32 characters of shelf
location information. The entered information is
recorded in the shelf location field in the volume
record in the TCDB. Specifying the LOCATION
keyword implies that the volume record be
retained upon completion of the EJECT operation.
{BULK | B}
Specifies that the tape volume be placed in the high-capacity or
“bulk” output station of the tape library. If neither BULK nor B is
specified, the tape volume is placed in the convenience output
station. If the high-capacity output station is not configured, the
cartridge is ejected to the convenience station. If a convenience
station is not installed in a 3494, the cartridge is placed in the
single cell output area. (This parameter is ignored for volumes
ejected from a MTL.)
To eject a tape cartridge from a tape library, enter the following command:
LIBRARY EJECT,TAP003
Specifying the Shelf Location
If you specify the LOCATION operand on the LIBRARY EJECT command, the
system issues the following message and waits for a reply:
CBR2601A
Specify shelf location for volume volser.
Provide 1 to 32 characters of shelf location information.
The following message displays when OAM accepts the EJECT command:
CBR1000I
OAM EJECT command execution scheduled.
One of the following messages displays upon successful completion of the eject
request:
CBR3010I
Volume volser ejected from library library-name.
location shelfloc.
Place in shelf
or
CBR3011I
Secure checkpoint volume volser ejected from library library-name.
Place in shelf location shelfloc.
If the ejected volume is reentered into a library before the eject completion message
is processed, the following message is issued in place of CBR3010I or CBR3011I:
Chapter 5. Operating the OAM Address Space
105
CBR3014I Eject processing completed for volume volser.
library-name detected.
Reentry into library
You can provide the shelf location by any of the following means:
v LIBRARY EJECT command
v Cartridge Entry Installation Exit (CBRUXENT)
v Cartridge Eject Installation Exit (CBRUXEJC)
v ISMF volume ALTER function
Note: ?????? is displayed in the eject completion messages if you have not
provided a shelf location.
Auditing a Volume
OAM provides an AUDIT command that enables you to audit an automated tape
library-resident tape volume.
Note: The audit function is not supported for volumes that reside in a manual
tape library.
The syntax of the command for the AUDIT function follows:
MODIFY
F
AUDIT
OAM, AUDIT ,
LIBRARY,library-name
VOLLIST,volser1,volser2...
VOLUME,volser
Specifies a request to audit a single volume, list of volumes, or an
entire tape library.
VOLUME | VOLLIST | LIBRARY
Specifies the scope of the audit.
volser
Specifies the volume serial number of the tape volume to be
audited. If VOLLIST is specified, up to 15 tape volumes can be
audited.
library-name
Specifies the name of the tape library to be audited.
Entering a Tape Volume into an MTL
Use the LIBRARY ENTER command to enter a tape volume into a manual tape
library.
The syntax of the command to enter a tape volume into an MTL follows:
106
LIBRARY
LI
ENTER
ENT
,volser ,library_name
,media_type
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
ENTER | ENT
Specifies a request to enter a volume into an MTL.
volser
Specifies the volume serial number of the volume to be entered
into the MTL.
library_name
Specifies the name of the library in which the volume is to be
entered.
media_type
Specifies the media type for the enter request:
MEDIA1
Specifies IBM Cartridge System Tape.
MEDIA2

You do not have to specify a media type; it is optional. If the media type is not
specified and a volume record does not already exist, the media type can be
derived from the entry default data class or the cartridge entry installation exit
(CBRUXENT), or both.
If no media type is determined by any of the above options, the entry will fail.
The LIBRARY ENTER command uses the LCS external services FUNC=MCE
programming interface to enter the volume into the MTL.
Importing Tape Volumes into a VTS
Use the LIBRARY IMPORT command to initiate or cancel an import operation at
the library. Before you can initiate an import operation, the import list volume
must be written to identify which volumes are to be imported. For information on
the 3494 VTS, refer to “Importing Logical Volumes into a 3494 VTS System” on
page 29. For information on the copy export support in the TS7740 Virtualization
Engine (3956-V06) and what mechanism is used to bring the copy exported
volumes back into a TS7740, refer to “Copy Export from the TS7740 Virtualization
Engine (3957-V06)” on page 39.
The syntax of the command to import volumes into a VTS follows:

used for this import operation.
CANCEL | C Requests that the currently executing import operation for the
specified volume serial number be canceled. This is an optional
parameter.
Exporting Tape Volumes from a VTS
Use the LIBRARY EXPORT command to initiate or cancel an export operation at
the library. Before you can initiate an export operation, the export list volume must
be written to identify which volumes are to be exported. For information on the
3494 VTS, refer to “Exporting Logical Volumes from a 3494 VTS System” on page
37, and for information on the copy export support in the TS7740 Virtualization
Engine (3956-V06), refer to “Copy Export from the TS7740 Virtualization Engine

used for this export operation.
CANCEL | C Requests that the currently executing export operation for the
specified volume serial number be canceled. This is an optional
parameter.
Requesting Information from the TS7700 Virtualization Engine
Use the MVS LIBRARY,REQUEST command to request information pertaining to
the current operational state of the TS7700 Virtualization Engine, its logical and
physical volumes, and its physical resources. This command can also be used to
perform outboard operations at the library. Based on the operation requested, the
library then returns information to the host that is displayed in a multi-line WTO
(CBR1280I). For a detailed discussion of the operations that are supported and the
keywords that can be specified, refer to IBM Redbooks, IBM System Storage

Disabling Installation Exit Processing
Use the LIBRARY DISABLE command to disable installation exit processing for a
particular system.
The following syntax is of the command to disable the installation exit processing:
110
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
LIBRARY
LI
DISABLE
DA
,
CBRUXENT
CBRUXVNL
DISABLE | DA
Specifies a request to disable the installation exit.
CBRUXENT
Specifies a request to disable cartridge entry installation exit
processing. Cartridge entry processing does not occur on this
system while the exit is disabled.
Note: Disabling the cartridge entry installation exit on a system
allows cartridge entry to be processed by another system,
which is connected to the library and has the cartridge entry
exit enabled. In effect, this directs cartridge entry processing
to a particular system.
With APAR OA24966 (z/OS V1R8 and above), the cartridge
entry installation exit can be disabled prior to the start of the
OAM address space to ensure that when the OAM address
space is started, entry processing is not attempted on the
disabled system.
CBRUXVNL
Specifies a request to disable volume not in library installation exit
processing.
Note: This does not disable job processing but does result in the
volume not in library installation exit being bypassed or not
called. In the absence of the CBRUXVNL installation exit's
intervention, Job Step Setup processing attempts to allocate
an applicable stand-alone tape drive for a volume that has
been inadvertently ejected from a tape library. If there is no
stand-alone drive capable of handling the tape volume
request, the job or dynamic allocation fails. During Device
Allocation or during Library Mount Processing, normal job
processing for a volume not in the library with no
CBRUXVNL installation exit intervention causes the failure
of the job step or dynamic allocation.
The following message displays upon successful completion of the disable request:
CBR1951I
Installation exit installation-exit-name has been disabled by operator command.
The installation exit processing on this system is disabled until a LIBRARY RESET
command is issued or the system is IPLed. Restarting the OAM address space does
not re-enable installation exit processing if it has been disabled by an operator
command. You can use command DISPLAY SMS,OAM to display the current status of
the installation exits.
Chapter 5. Operating the OAM Address Space
111
Reenabling Installation Exit Processing
When OAM detects an error during installation exit processing, the function that is
being performed when the exit is invoked is disabled. For example, cartridge entry,
cartridge eject, private-to-scratch change use attribute, or volume-not-in-library
processing is not performed. An installation exit might also request, by way of a
return code, that the exit not be invoked again, and function processing continues
without the exit. Also an operator, through the use of the MVS LIBRARY DISABLE
command, might request that cartridge entry processing on a particular system be
disabled, or request that the volume not in library exit be disabled. Use the MVS
LIBRARY RESET command to reenable installation exit processing.
The syntax of the command to reestablish installation exit processing follows:
LIBRARY
LI
RESET | R
RESET
R
,
CBRUXEJC
CBRUXENT
CBRUXCUA
CBRUXVNL
Specifies a request to reactivate an installation exit.
CBRUXEJC | CBRUXENT | CBRUXCUA | CBRUXVNL
Specifies which exit to reactivate.
CBRUXEJC
Specifies that the cartridge eject installation exit (CBRUXEJC) be
reactivated.
CBRUXENT
Specifies that the cartridge entry installation exit (CBRUXENT) be
reactivated.
CBRUXCUA
Specifies that the change use attribute installation exit
(CBRUXCUA) be reactivated.
CBRUXVNL
Specifies that the volume not in library installation exit
(CBRUXVNL) be reactivated.
Note: Resetting the CBRUXENT installation exit invokes cartridge entry processing
for volumes in the insert category.
Displaying the Cartridge Loader Scratch Media Type
Use the MVS LIBRARY DISPCL command to display the media type of scratch
volumes that you want loaded into the cartridge loader of a library-resident tape
drive. The syntax of the LIBRARY DISPCL command follows:
LIBRARY
LI
DISPCL
DC
,device_number
DISPCL | DC Specifies a request to display the media type of scratch volumes
you want loaded into the cartridge loader for a library-resident
tape drive.
112
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
device_number
Specifies the MVS device number of a library-resident tape drive.
Note: The display output for the DISPCL command is the same as the output for
the DISPDRV command for a single drive. See “Displaying Tape Drive
Status” on page 126 for an example.
Setting the Cartridge Loader Scratch Media Type
Use the MVS LIBRARY SETCL command to set the media type of scratch volumes
to be loaded into the cartridge loaders of library-resident tape drives. The syntax of
the LIBRARY SETCL command follows:
LIBRARY
LI
SETCL
SC
,
device_number
device_range

NONE
In an ATLDS, the cartridge loader is emptied. In an
MTL, indexing is not occurring on this system;
however, indexing could be occurring on another
system.
ANY

Chapter 5. Operating the OAM Address Space
113
through data class is not being used; therefore,
index with media appropriate for the drive.
Note: Use this command only for devices in a tape library that have installed
cartridge loaders.
Assigning Categories to ATLDS Cartridge Loaders
At the first IPL after the library is configured, media type defaults are no longer
set for the cartridge loaders by the system so they remain set to NONE.
Use the LIBRARY SETCL command to assign a media type to the tape library data
server cartridge loaders. Once the LIBRARY SETCL command is used, the media
type that is assigned to the cartridge loader is preserved. Subsequent IPLs will not
modify the assignment. Use the LIBRARY DISPCL command to display the media
type.
Assigning Media Types to MTL Cartridge Loaders
For devices in an MTL, the media type setting is not maintained across an IPL and
defaults to NONE. You can use the LIBRARY SETCL command to set the media
type. However, in an MTL environment, you must issue this command to each
sharing system.
Media Selection in an ATLDS
For nonspecific volume requests, the media type assigned to the cartridge loader is
preferred if data class is not specified through the data class JCL parameter or
through the ACS filter routines. If that scratch category is empty, an appropriate
alternate media type is selected. However, if the category assigned to the cartridge
loader is NONE, then MEDIA2 is preferred for a 3490E, and MEDIA4 is preferred
for a 3590. MEDIA5 is preferred for a 3592 Model J, with MEDIA7 as the alternate
media type. MEDIA5 is preferred, with MEDIA7 as the alternate media type when
EFMT1 recording format is requested on a 3592 Model J or 3592 Model E05 drive.
MEDIA9 is preferred, with MEDIA5 and MEDIA7 as the alternate media types,
using the EEFMT2, EFMT3, or EEFMT3 format, or when no recording technology
has been specified and a 3592 Model E05 or 3592 Model E06 is allocated. 3592
WORM media (MEDIA6, MEDIA8 and MEDIA10) can only be used for a
nonspecific volume request when explicitly requested through data class. If a
specific media type is selected using data class, only that media type is used.
If a data set spans multiple volumes, the subsequent volumes are written using the
media type of the last volume written. If the scratch category for the media type is
empty, rather than fail the job, an appropriate alternate media type is selected.
Media Selection in an MTL
For nonspecific volume requests, the cartridge loader media type assignment
through the LIBRARY SETCL command plays an important role. It lets the system
know the intended use of the cartridge loader and whether indexing is to occur on
this system. If indexing is to occur, it indicates what media type should be loaded
in the cartridge loader. If a media type is then preferenced through DATACLASS,
an attempt to index the cartridge loader is made only if the media type that is
assigned to the device matches the DATACLASS specification. If DATACLASS does
not specify a media type, indexing occurs on those systems where the cartridge
loader is not set to NONE. If there is no intention to preference a specific media
114
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
type, all of the cartridge loaders could be set to ANY. This then enables you to
load any appropriate media type for the device. After an IPL, the cartridge loaders,
by default, are set to NONE.
Assigning Policy Names Outboard
Use the LIBRARY LMPOLICY command to assign or change a volume's policy
names outboard at the library. You can use this command only for private,
library-resident volumes that reside in a library that supports outboard policy
management.
The processing for the LIBRARY LMPOLICY command invokes the LCS external
services FUNC=CUA interface. Any errors that the CUA interface returns can also
be returned for the LIBRARY LMPOLICY command. See “Return and Reason
Codes for CBRXLCS Change Use Attribute” on page 156 for more information on
these return codes. If the change use attribute installation exit (CBRUXCUA) is
enabled, the CUA function calls the installation exit. This can override the policy
names that you set using the LIBRARY LMPOLICY command. The results of this
command are specified in the text section of message CBR1086I. To verify the
policy name settings and to see whether the CBRUXCUA installation exit changed
the policy names you set, display the status of the volume. See “Displaying Tape
Volume Status” on page 133.
The syntax of the LIBRARY LMPOLICY command to assign or change volume
policy names is as follows:
LIBRARY
LI
,SG=
,SC=
,MC=
,DC=
LMPOLICY
LP
, volser
storage_group_name
*RESET*
storage_class_name
*RESET*

The following parameters are required:
Required Parameters
LMPOLICY | LP
Specifies a request to set one or more of a private volume's policy names
outboard in the library in which the volume resides. The library must
support outboard policy management.
volser
Specifies the volume serial number of a private volume which resides in a
library with outboard policy management support.
You must specify at least one of the following optional parameters. These
parameters can be specified in any order:
Optional Parameters
Chapter 5. Operating the OAM Address Space
115
SG={storage_group_name | *RESET*}
Specifies a construct name for the SG parameter. If the request is
successful, the construct name becomes the storage group for the
volume in the TCDB and the storage group policy name in the
library. If you specify the *RESET* keyword, you are requesting
that OAM set the volume's storage group name to blanks in the
TCDB, and to the default storage group policy in the library, which
is also blanks.
SC={storage_class_name | *RESET*}
Specifies a construct name for the SC parameter. If the request is
successful, the construct name becomes the storage class policy
name for the volume in the library. If you specify the *RESET*
keyword, you are requesting that OAM set the volume's storage
class name to the default storage class policy in the library, which
is blanks.
MC={management_class_name | *RESET*}
Specifies a construct name for the MC parameter. If the request is
successful, the construct name becomes the management class
policy name for the volume in the library. If you specify the
*RESET* keyword, you are requesting that OAM set the volume's
management class name to the default management class policy in
the library, which is blanks.
DC={data_class_name | *RESET*}
Specifies a construct name for the DC parameter. If the request is
successful, the construct name becomes the data class policy name
for the volume in the library. If you specify the *RESET* keyword,
you are requesting that OAM set the volume's data class name to
the default data class policy in the library, which is blanks.
Rule: The values you specify for the SG, SC, MC, and DC policy names must meet
the Storage Management Subsystem (SMS) naming convention standards:
v Alphanumeric and national characters only
v Name must begin with an alphabetic or national character ($*@#%)
v No leading or embedded blanks
v Eight characters or less
Construct Validity Checking
The SG specification must be a tape storage group that is defined in the active SMS
configuration. The library in which the volume resides must be defined to that
storage group. The SC, MC, and DC specification is only checked to ensure that it
conforms to SMS naming convention standards. It is not checked against the
current active SMS configuration. Use the D SMS, VOLUME command to ensure
that correct names are assigned at the library. See “Displaying Tape Volume Status”
on page 133.

The media type, scratch count, scratch threshold, and scratch category lines are
displayed only for media that have a threshold value or a scratch count greater
than zero. The scratch category counts displayed are returned from the library and
reflect the number of usable scratch volumes. The counts displayed do not include
volumes assigned to the software error category or volumes in the VTS that are in
a delete-expire-hold state. Therefore, the scratch category counts displayed may be
less than the scratch counts that appear elsewhere (for example, through ISMF).
In an MTL, the scratch counts that are displayed reflect the current counts that are
maintained in the TCDB library record. This is meant to be an approximation.
Without having an external source to derive the count, the scratch count from that
point forward may be inaccurate if an update of this count in the catalog fails.
Periodically check the scratch counts against your tape management system or the
TCDB volume records. Also, for an MTL, the scratch category is not applicable and
is displayed as zeros for all media types.
For a VTS composite or distributed library, the appropriate composite or
distributed line will be displayed, mapping the association of the VTS to the
appropriate library.
The library ID line displays the five-character ID assigned to the library.

The cache percentage used will only be displayed for a TS7720 (3957-VEA)
distributed library or for a TS7680 (3958-DE2); it indicates what percentage of
cache the library has utilized.

For an ATLDS, the error category displays the total number of scratch volumes
that have a software error associated with them. Scratch volumes in this category
will still have a use attribute of scratch; however, they are not eligible to be
mounted.
The scratch stacked volume count is only displayed for a virtual tape server (VTS)
library and indicates the number of available physical scratch volumes. For a
Peer-to-Peer VTS subsystem, this information can be obtained by displaying the
distributed libraries associated with the composite library. This count is suppressed
when the library being displayed is a TS7720 (3957-VEA).
The private stacked volume count will only be displayed for a VTS library. This
count indicates the number of physical stacked private volumes. For a Peer-to-Peer
VTS subsystem, this information can be obtained by displaying the distributed
libraries associated with the composite library. This count is suppressed when the
library being displayed is a TS7720 (3957-VEA).
For a VTS library with outboard policy management support, the scratch stacked
volume count and the private stacked volume count will reflect the cumulative
count from all physical volume storage pools. See “Physical Volume Pooling” on
page 20 for more information on physical volume pooling.
The corrupted token volume count will only be displayed for a Peer-to-Peer VTS
library and indicates the number of volumes in the corrupted token category. For a
Peer-to-Peer VTS subsystem, this information can be obtained by displaying the
composite library. For corrective action, contact your hardware service
representative.
For a VTS composite library, the operational state that is returned to the host is
determined by examining the states of the underlying distributed libraries with
much of the other status (for instance, I/O station-related status), being provided
from the designated user interface (U/I) library. Also, since all of the drives and
volumes are defined to and associated with the composite library, the display of a
distributed library will show that, from a host perspective, there are no volumes
and drives associated with that library. The distributed libraries should be
displayed for an accurate picture of the total and empty slot counts (the slot counts
associated with the composite library are zero).
The high capacity input and output station lines are only displayed for an ATLDS
and only if the station has been configured.
In an ATLDS, the following status lines may appear:
v Operation degraded due to unavailable hardware resource
v Safety enclosure interlock open
v Vision system not operational
v Library manager offline
v Operator intervention required
v Library manager check 1 condition
v All storage slots full
v Out of cleaner volumes

3400
This is a 3400 magnetic tape drive.
UNKNOWN
Tape device is not recognized.
Whether a device defined through HCD is real or emulated is not
determined until successful communication to the device has been
made. Until successful communication has been made, the device
type displayed will reflect the device type defined through HCD.
Thus for emulated devices, beginning with the 3590 Model E, the
device type displayed reflects the emulated device type defined
through HCD rather than the real underlying device type (3590-E,
3590-H, 3592-J, 3592-2, 3592-2E and 3592-3E). Once successful
communication to the device has been established, the device type
displayed will reflect the real underlying device type.
Also, on system levels that support the emulated device type
defined through HCD, but do not support the real underlying
device type (such as the 3590 Model E, 3590 Model H, 3592 Model
J, 3592 Model E05, or 3592 Model E06), the device type displayed
reflects the emulated device type that is defined through HCD.
libname
Name or ID of the library in which the tape drive resides. For a
stand-alone tape drive (nonlibrary-resident drive), this field
contains ‘--N/A--’.
The library name is stored during OAM initialization (or during
library VARY processing) for those devices in the library returned
by device services. If, after this process, devices in a subsystem are
128
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
subsequently varied online, the library name displayed may reflect
the LIBRARY-ID. As long as the correct library name or library ID
is displayed, having the LIBRARY-ID appear in the display should
not pose a problem. See “Creating the Hardware Configuration” on
page 80 for more information.

2. To differentiate between logical and physical WORM, "Volume is WORM tape"
will be displayed for a physical WORM volume and "Volume is logical WORM"
will be displayed for a logical WORM volume. In addition to this, since a
logical volume will retain its WORM state (at the library) until the volume is
reused and written from load point; this status line can also be displayed for a
scratch volume, reflecting the past usage of the volume.

Capturing OAM Diagnostic Data
OAM uses SVC dumps as a diagnostic tool for system hangs or performance
problems. To capture this data, issue the DUMP command after the problem has
been recreated or at the time of failure. OAM provides a streamlined version of the
previous DUMP command. The F OAM,DUMP,(operands) command automatically
collects all the pertinent data needed for diagnostic purposes without you having
to key in all the correct parameters.
The syntax of the F OAM,DUMP command follows:
140
MODIFY
F
OAM, DUMP,
OAM
ALL
ASID,asid1,asid2,...
JOBN,jobname1,jobname2,...
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Note: OAM is the default name of the cataloged procedure in your
SYS1.PROCLIB. If a name other than OAM is used for the cataloged
procedure, use that name in the DUMP statement. For example, MODIFY
procname_name,DUMP,OAM.
OAM
Specifies a request to schedule an SVC dump for the OAM address space. If
the first operand after the DUMP verb is either OAM or blank, OAM
schedules an SVC dump for the OAM address space.
ALL
An SVC dump is scheduled for the OAM address space and any address
spaces which currently have work queued to the OAM address space, up to 14
address spaces in addition to OAM.
If the first operand after the DUMP verb is ALL, OAM scans all queues to
identify address spaces that are not the OAM address space. OAM scans until
all queues are searched or 14 address spaces are found. OAM then schedules
an SVC dump for the OAM address space and up to 14 other address spaces
that currently have work queued in the OAM address space.
ASID (address space identifier),asid1,asid2,asid3...
An SVC dump is scheduled for the OAM address space and any address
spaces specified after the ASID operand separated by commas. A valid ASID is
a 1 to 4 hexadecimal (0–9, A–F) value. From one to 14 ASIDs can be specified
with the ASID operand. If more than 14 ASIDs are specified, the first 14 will be
used.
If the first operand after the DUMP verb is ASID, OAM validates that any
ASIDs specified following the ASID operand are valid hexadecimal characters
(0–9, A–F). If they are valid, OAM, schedules an SVC dump for the OAM
address space and any additional address spaces specified (up to 14 address
spaces in addition to OAM).
JOBN (job name),jobname1,jobname2,jobname3...
An SVC dump is scheduled for the OAM address space and any job spaces
specified after the JOBN operand separated by commas. A valid job name is a
1 to 8 character value of the following character set:
v Alphanumeric characters (A–Z, 0–9)
v National characters (&, $, @)
v Wildcard characters (*, ?) where ‘*’ can stand for 0 or more characters, up to
the maximum length of the job name string (8) and ‘?’ can stand for one
character.
From one to 14 job names can be specified with the JOBN operand. If more
than 14 job names are specified, the first 14 will be used.
If the first operand after the DUMP verb is JOBN, OAM validates that any job
names specified following the JOBN operand contain the valid character set. If
they are valid, OAM schedules an SVC dump for the OAM address space and
any job names specified (up to 14 jobs in addition to OAM).
OAM issues messages for any errors found in the DUMP command at SVC
scheduling time and at SVC DUMP data capture completion. For more information
concerning these messages, see z/OS MVS System Messages, Vol 4 (CBD-DMO).

Chapter 6. Library Control System (LCS) External Services
Library Control System (LCS) External Services provides a programming interface
that allows you to access and manipulate information about each tape volume
record in the TCDB.
LCS External Services Overview
The executable macro CBRXLCS is used to invoke the LCS External Services to
perform the following functions:
v Change the use attribute of a volume
v Enter one or more volumes into a manual tape library
v Eject a tape cartridge from a tape library
v Query the name and type of a tape library where a specified volume resides
v Determine whether a tape volume can be mounted on a specific device
v Export a list of logical volumes from a VTS
v Import a list of logical volumes into a VTS
v Change current operating modes of a Peer-to-Peer VTS library
v Obtain operational mode settings and device-related information from a
Peer-to-Peer VTS library
v Obtain library name information
Note: You might have an environment with multiple systems at different levels
sharing a common TCDB. In this event, if a system attempts to perform a
CBRXLCS function against a volume that has a media type or recording
technology that is not recognized, the request fails.
Change Use Attribute (CUA)
The change use attribute (CUA) function changes the status of the specified
volume from PRIVATE to SCRATCH, SCRATCH to PRIVATE, PRIVATE to
PRIVATE, or SCRATCH to SCRATCH, and updates the tape volume record in the
TCDB. It also calls the change use attribute installation exit to allow the installation
to approve or disapprove the change in the volume status and to set values for
many of the fields in the volume record. See “Change Use Attribute Installation
Exit (CBRUXCUA)” on page 211.
Manual Cartridge Entry (MCE)
The manual cartridge entry (MCE) function allows the user to enter a list of one or
more tape cartridges into a manual tape library. When the MCE function is
invoked, a tape volume record is created or updated in the TCDB. MCE calls the
cartridge entry installation exit to allow the installation to approve or disapprove
the entry of the cartridge into the manual tape library, and to set values for many
of the fields in the volume record. For more information regarding the cartridge
entry installation exit, see “Cartridge Entry Installation Exit (CBRUXENT)” on page
221.
Cartridge Eject (EJECT)
The cartridge eject (EJECT) function of the LCS External Services provides two
major functions for tape cartridge ejects:
v Can eject a tape volume from a tape library. The tape volume record in the
TCDB may be kept or purged. The cartridge eject installation exit is also called
© Copyright IBM Corp. 1993, 2010
147
to allow the installation to approve or disapprove the eject request. If the eject
request fails after the installation exit is invoked, the exit can also specify that a
second failed eject notification call be made to the exit. See “Cartridge Eject
Installation Exit (CBRUXEJC)” on page 232 for more information regarding the
cartridge eject installation exit.
v Can determine the eject status of a tape volume. Use the QUERY option of the
EJECT function to determine if a volume has an eject request pending on an
OAM internal queue. This use of the EJECT function does not invoke the
cartridge eject installation exit, as it is only a query. See “Ejecting a Tape
Cartridge” on page 163 for more information on this function.
Query Volume Residence (QVR)
The query volume residence (QVR) function allows the installation to query the
residency and type of library in which a specified volume resides. It also returns
the console name associated with the library, if one has been specified by the
installation, and if requested, other available information about the volume from
the TCDB and library manager inventory.
Additionally, QVR provides audit capabilities from a tape management system
database, since QVR does not require the presence of a TCDB record to perform
this audit. A tape management system can use this capability to verify its
inventory against the TCDB and the library manager inventory. It can also be used
to track and verify the library residency of volumes that are not managed in the
TCDB, such as stacked volumes in a VTS. See “Querying the Residence of a
Volume” on page 166.
Test Volume Eligibility (TVE)
The test volume eligibility (TVE) function verifies that the specified tape volume
serial number can be mounted on the specified tape device. See “Testing the
Eligibility of a Volume” on page 171.
Export Logical Volumes (EXPORT)
After the tape management system or customer utility has written the list of logical
volumes to export on an export list volume (logical volume residing in the same
library as the volumes to be exported), the export function can be used to identify
the logical volumes to export and to initiate the export operation at the library.
This interface can also be used to cancel an executing export operation. See
“Exporting Logical Volumes from a VTS” on page 173.
Import Logical Volumes (IMPORT)
After the tape management system or customer utility has written the list of logical
volumes to import on an import list volume (logical volume residing in the same
library as the volumes to be imported), the import function can be used to identify
the logical volumes to import and to initiate the import operation at the library.
This interface can also be used to cancel an existing import operation. See
“Importing Logical Volumes into a VTS” on page 175.
Peer-to-Peer Mode Control (PTPMC)
The Peer-to-Peer VTS mode control (PTPMC) function allows an installation or
application to change current operating modes of the library. This CBRXLCS
function is not supported by the TS7700 Virtualization Engine. If invoked, the
148
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
PTPMC function fails with Return Code 12, Reason Code 322, 'Command rejected
by the library'. See “Changing Library Operating Modes (Peer-to-Peer VTS Mode
Control)” on page 177.
Peer-to-Peer Data (PTPDATA)
The Peer-to-Peer VTS data (PTPDATA) function allows an installation or
application to obtain operational mode settings and device-related information
from the PTP VTS library. This CBRXLCS function is not supported by the TS7700
Virtualization Engine. If invoked, the PTPDATA function fails with Return Code
12, Reason Code 322, 'Command rejected by the library'. See “Obtaining
Operational Mode Settings (Peer-to-Peer VTS Data)” on page 180.
Obtain Library Name Information (OLN)
The obtain library name information (OLN) function of the LCS External Services
macro allows you to obtain the library name or library ID, the console name, an
indication of whether outboard policy management is supported, and the library
type. See “Obtaining Library Name Information (OLN)” on page 182.
LCS External Services Functions
An executable macro called CBRXLCS is used to invoke the functions provided by
LCS External Services. The macro expansion sets parameter values in the LCS
External Services parameter list (LCSPL), which is mapped by the CBRLCSPL
macro, retrieves the entry point for LCS External Services, and branches to perform
the requested function. See “CBRXLCS Macro Interface” on page 184 for the
CBRXLCS macro usage, return and reason codes, and parameter list.
This section provides the syntax, required and optional parameters, and return and
reason codes for each CBRXLCS function.

volume serial number of the volume whose use attribute is to be changed. The
volume serial number must be left justified in the field and padded on the
right with blanks. If the volume resides in a library, the library must be
defined in the active SMS configuration.
Optional Parameters
DEVTYPE=tape-device-selection-information-address
Specifies the name of a variable which contains the address of the tape device
selection information to be associated with the data sets written on this tape
volume. The TDSI is mapped by the structure CBRTDSI (see Figure 18 on page
208), and consists of four 1-byte fields which specify recording technology,
media type, compaction indicator, and special attribute to be associated with
the volume.
The following fields in the TDSI may be specified on a CUA request:
v Recording technology may be specified as unknown, 18TRACK, 36TRACK,
128TRACK, 256TRACK, 384TRACK, EFMT1, EFMT2, EEFMT2, EFMT3, or
EEFMT3.
v Media type may be specified as unknown, MEDIA1, MEDIA2, MEDIA3,
MEDIA4, MEDIA5, MEDIA6, MEDIA7, MEDIA8, MEDIA9, or MEDIA10.
v Compaction may be specified as unknown, none, or compacted.
v Special attribute may be specified as none or read compatible.
Any nonzero TDSI field specified for input is merged with the tape device
selection information recorded on the volume record. If incompatible tape
device selection attributes, such as 36TRACK recording technology and
MEDIA4 media type, result from merging the input, an error is returned and
CUA processing is not performed. If CUA processing is successful, the TDSI in
the volume record in the TCDB is updated with the new, merged values.
DEVTYPE is used only when USE=PRIVATE is specified, and is otherwise
ignored.
EXPDATE=volume-expiration-date
Specifies the name of a variable (four-byte length), which contains the
expiration date assigned to the volume. The expiration date should be
specified in TIME DEC format; for example, packed decimal digits of the form
0CYYDDDF. This field is only used when USE=PRIVATE is specified, and is
Chapter 6. Library Control System (LCS) External Services
151
otherwise ignored. If the change use attribute installation exit is invoked, the
value specified by the exit may override the volume expiration date.
GRPNAME=storage-group-name
Specifies the name of a character variable (8-byte length) that contains the
name of the storage group to which the volume belongs. The storage group
name must be left-justified in the field and padded on the right with blanks, if
necessary. This field is only used when USE=PRIVATE is specified, and is
otherwise ignored. If a nonblank storage group name is specified on a change
to PRIVATE, the storage group must be a tape storage group that is defined in
the active configuration. Additionally, if the volume is library-resident, the
library must also be defined to the storage group. If a storage group name is
specified and there is a change from PRIVATE to PRIVATE, the existing storage
group name in the volume record is updated. On a change from PRIVATE to
PRIVATE, if no storage group name is specified, the existing storage group
name in the TCDB is retained. On a change from SCRATCH to PRIVATE, if no
storage group name is specified, the field is set to blanks. If the change use
attribute installation exit is invoked, the value specified by the exit may
override the storage group name. To be consistent with the existing or
resulting storage group name in the TCDB, the storage group name is also
assigned as the private volume's outboard storage group policy, if the library
supports outboard policy management.
WRTDATE=YES
Specification of this keyword requests the update of the date when a data set
was last opened for OUTPUT. The tape volume record is updated with the
current date, as returned by the MVS TIME macro, translated into ISO format
(YYYY-MM-DD). When this keyword is specified the last mounted date is also
set to the current date. This field is only used when USE=PRIVATE is specified,
and is otherwise ignored. If the change use attribute installation exit is
invoked, it may override the last written date and last mounted date.
WRTPROT=write-protection-status
Specifies the name of a character variable (1-byte length) which contains the
volume write protection status. If the write-protect tab is set on the tape
cartridge, this field should be set to “Y”; if the write-protect tab is not set, this
field should be set to “N”; if the tab setting is unknown, it should be set to
blank. This field is only used when USE=PRIVATE is specified, and is
otherwise ignored. If the change use attribute installation exit is invoked, the
value specified by the exit may override the write protection status.
EXITINFO=installation-exit-information
Specifies the name of a character variable (16-byte length) that contains a
customer specified free-form value to be passed to the change use attribute
installation exit (CBRUXCUA).
GETPOLICY=YES
Specifies a request to retrieve the current outboard policy names for a volume
from the library. The library policy names are stored in the CBRUXCPL
parameter list in the UXCLMSG, UXCLMSC, UXCLMMC, and UXCLMDC
fields and passed to the CBRUXCUA installation exit. Blanks in a policy field
indicate that the volume has the default policy for that construct assigned to it.
If GETPOLICY=YES is specified, the CBRUXCUA installation exit can examine
the UXCVLOPM indicator to determine if the policy names have been
retrieved and stored in the UXCLMOPM fields.
If one or more of the UXCLMSC, UXCLMMC, and UXCLMDC fields is
changed by the CBRUXCUA installation exit and the volume use attribute is
PRIVATE (PRIVATE to PRIVATE invocation), constructs that are changed are
152
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
updated in the library. Blanks specified in a policy field indicate that the
default policy is requested. The storage group for the TCDB volume record
and the outboard storage group policy is specified in UXCGROUP. The
UXCLMSG is an input-only variable.
If GETPOLICY=YES is not specified, the library manager policy names are not
retrieved and passed to the exit. The GETPOLICY option is ignored if outboard
policy management is not supported in the library in which the volume
resides. It is also ignored on SCRATCH-to-SCRATCH, PRIVATE-to-SCRATCH,
and SCRATCH-to-PRIVATE CUA invocations and all CUA invocations for
shelf-resident volumes.
GETPOLICY=YES and the GRPNAME, SCNAME, MCNAME, and DCNAME
parameters are mutually exclusive.
SCNAME=storage-class-name
Specifies a request to set a construct name in the library where the specified
volume resides as its outboard storage class policy. The storage-class-name is an
8-byte character variable, left justified, and padded on the right with blanks, if
necessary. If blanks are specified, the request is to set the volume's storage
class library policy to the default policy. If a nonblank storage class name is
specified, it is only validity checked against Storage Management Subsystem
(SMS) naming convention standards and is not checked to see if it is defined in
the active configuration.
The SCNAME option is ignored if outboard policy management is not
supported in the library in which the volume resides, if USE=SCRATCH, or if
the volume is shelf-resident.
MCNAME=management-class-name
Specifies a request to set a construct name in the library where the specified
volume resides as its outboard management class policy. The
management-class-name is an 8-byte character variable, left justified, and padded
on the right with blanks, if necessary. If blanks are specified, the request is to
set the volume's management class library policy to the default policy. If a
nonblank management class name is specified, it is only validity checked
against SMS naming convention standards and is not checked to see if it is
defined in the active configuration.
The MCNAME option is ignored if outboard policy management is not
supported in the library in which the volume resides, if USE=SCRATCH, or if
the volume is shelf-resident.
DCNAME=data-class-name
Specifies a request to set a construct name in the library where the specified
volume resides as its outboard data class policy. The data-class-name is an
8-byte character variable, left justified, and padded on the right with blanks, if
necessary. If blanks are specified, the request is to set the volume's data class
library policy to the default policy. If a nonblank data class name is specified, it
is only validity checked against Storage Management Subsystem (SMS) naming
convention standards and is not checked to see if it is defined in the active
configuration.
The DCNAME option is ignored if outboard policy management is not
supported in the library in which the volume resides, if USE=SCRATCH, or if
the volume is shelf-resident.

Successful Change Use Attribute Processing
When the change use attribute function is successful, the following processing
occurs:
v The use attribute of the volume specified with the VOLUME keyword is
changed to the requested value.
v The tape volume record is updated with the values specified on the CBRXLCS
macro invocation, by the change use attribute installation exit, or both.
v If the volume resides in an ATLDS, the category of the volume is also changed
in the hardware inventory to the requested value.
v If the library supports outboard policy management, the SMS construct names
are passed to the library.
Unless the change use attribute installation exit (CBRUXCUA) has been disabled or
the installation has indicated that it should not be called, the change use attribute
installation exit is invoked for every request to change the use attribute of a
volume. See “Change Use Attribute Installation Exit (CBRUXCUA)” on page 211
for further discussion of the exit.
Changing the Use Attribute from SCRATCH to PRIVATE
For a request to change a volume to PRIVATE, the optional parameters which are
specified on the CBRXLCS invocation are passed to the installation exit for
approval. The exit may override the values supplied on the macro invocation, and
the values supplied by the exit are committed to the tape volume record if CUA
processing is successful.
Changing the Use Attribute from PRIVATE to SCRATCH
For a request to change a volume to SCRATCH, optional parameters are ignored
on the CBRXLCS macro invocation. Upon return from the installation exit, the
following default values are set in the tape volume record:
v Volume use attribute = S
v Storage group name = *SCRTCH*
v Write protection status = N
v Checkpoint volume indicator = N
v Volume expiration date = blank
v Tape device selection values
– Recording technology is unchanged
– Media type is unchanged
– Compaction indicator is unchanged
– Special attribute is set to none
v If the library supports outboard policy management, default policy names
(blanks) are passed to the library.
When the volume whose use attribute is to be changed resides in a tape library, a
call is made to the hardware to change the category of the volume. If the hardware
change is not successful, the tape volume record is not updated and CUA
154
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
processing fails. If the category of the volume is successfully changed, the scratch
count for the library is updated with the number of scratch cartridges returned
from the hardware.
If changing the use attribute of the volume causes the number of scratch volumes
of a particular type in a library to fall below the scratch volume threshold
established through the ISMF library management application, operation action
message CBR3660A is issued requesting that the operator add the appropriate type
of scratch cartridges to the library. If CUA processing causes the scratch count to
exceed twice the scratch volume threshold for the scratch type being processed,
operation action message CBR3660A is deleted if it is outstanding.

Changing a WORM Tape Volume's Use Attribute
Because OAM has no knowledge of whether a volume contains user data and
because volumes may be entered incorrectly as PRIVATE when they are really
SCRATCH, OAM does not prevent changing a WORM volume from PRIVATE to
SCRATCH (for either physical or logical WORM). Also, when you invoke the
CBRUXCUA installation exit, a UXCVWORM indicator in the CBRUXCPL
parameter list is set on when the volume is a physical WORM tape to alert the
tape management system that the CUA function is being performed for a WORM
volume. Because a logical WORM volume is not distinguishable by a unique media
type, the UXCVWORM indicator is not turned on for a logical WORM volume. If
this information is needed, the CBRUXCUA installation exit can invoke the
CBRXLCS FUNC=QVR interface to obtain this information from the library.
Changing to the Same Use Attribute
When the requested use attribute is the same as the existing use attribute (for
example, the change from PRIVATE to PRIVATE or from SCRATCH to SCRATCH
), the tape volume record is updated with values specified on the CBRXLCS macro
invocation, the installation exit, or both; however, a warning return code is
returned. In both cases, if the volume resides in a tape library, a call is made to the
library to change the category of the volume in the library manager inventory.
Setting Policy Names Outboard Using Keywords
The CUA function allows you to set policy names outboard using keywords. If
GRPNAME is specified on the CUA invocation and the volume is a private volume
residing in a library with outboard policy management support, the valid storage
group name specified in GRPNAME is assigned as the volume's outboard storage
group policy. If GRPNAME is not specified, the TCDB storage group name is
assigned as the private volume's outboard storage group policy (PRIVATE to
PRIVATE CUA).
You can use the SCNAME, MCNAME, and DCNAME keywords to specify values
for policy names for the storage class, management class, and data class constructs.
One or more of these options can be specified. The fourth policy construct is
specified using the existing GRPNAME option. The GETPOLICY keyword cannot
be specified at the same time as the GRPNAME, SCNAME, MCNAME, and
DCNAME options.
For a scratch volume, the CUA function sets the default policy names outboard;
these names consist of blanks. The GRPNAME, SCNAME, MCNAME, and
DCNAME options are ignored on SCRATCH-to-SCRATCH and
PRIVATE-to-SCRATCH CUA invocations, as scratch volumes are always assigned
default policy names.

Parameter Descriptions
TYPE=TAPE
Specifies a request related to the TCDB.
FUNC=MCE
Specifies a request to enter a list of one or more volumes into a manual tape
library.
LIBNAME=library-name
Specifies the name of a character variable (eight-byte length) that contains the
fully-specified library name. The library name must be left justified in the field
and padded on the right with blanks.
VOLLIST=volume-list-pointer
Specifies a variable that contains the address of the list of volumes to be
entered into the manual tape library.
The volume list mapping, LCSV and LCSMLIST, is declared in mapping macro
CBRLCSPL. LCSV is the header for the volume list, and LCSMLIST maps the
array of volumes and the associated information for each. Volume-list-pointer
contains the address of the list header.
Each member of the volume list array contains the volume serial number,
left-justified in a six-character field and padded on the right with blanks; a
six-byte reserved area; a four-byte field for tape device selection information
(TDSI); and two full words into which LCS External Services stores the return
code and reason code for this volume.
Processing the Tape Device Selection Information (TDSI)
The tape device selection information for each volume is processed as follows:
v If a volume record exists for the volume to be entered into the manual tape
library, all TDSI values are ignored and the values from the existing volume
record are passed to the cartridge entry installation exit (CBRUXENT).
v If no volume record exists for the volume to be entered into the manual tape
library, TDSI values are processed as follows:
– Recording technology specified in TDSI is ignored. A volume's recording
technology may be determined by using the library's default entry data class,
if applicable, by a default recording technology based on the media type, or
explicitly set by the CBRUXENT installation exit. If the volume is a
SCRATCH volume, UNKNOWN is also a possible recording technology
value.
- If the volume is MEDIA1 and the entry default data class is not defined for
the library or is not applicable for the volume's media type, by default,
36-track is passed to the exit. UNKNOWN can be passed to the exit for a
158
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
-
-
-
-
SCRATCH volume if the default data class is not defined. The installation
exit may set an applicable value (18-track, 36-track).
If the volume is MEDIA2, 36-track is passed to the exit because this is the
only applicable recording technology.
If the volume is MEDIA3 or MEDIA4, and the entry default data class is
not defined for the library or is not applicable for the volume's media type,
by default, 128-track is passed to the exit. UNKNOWN may be passed to
the exit for a SCRATCH volume if the default data class is not defined. The
installation exit may specify an applicable recording technology (128-track,
256-track, 384-track).
If the volume is MEDIA5, MEDIA6, MEDIA7, or MEDIA8 and the entry
default data class is not defined for the library or is not applicable for the
volume's media type, by default, EFMT1 is passed to the exit. UNKNOWN
may be passed to the exit for a SCRATCH volume if the default data class
is not defined. The installation exit may specify an applicable recording
technology (EFMT1, EFMT2, EEFMT2, EFMT3, or EEFMT3).
If the volume is MEDIA9 or MEDIA10 and the entry default data class is
not defined for the library or not applicable for the volume's media type,
by default, EFMT2 is passed to the exit. UNKNOWN may be passed to the
exit for a SCRATCH volume if the default data class is not defined. The
installation exit may specify an applicable recording technology (EFMT2,
EEFMT2, EFMT3, or EEFMT3).
PRIVATE volumes must have an applicable recording technology set.
SCRATCH volumes can be entered with an applicable recording technology
or UNKNOWN.
– Media type for the volume must be set before the volume can be entered into
the manual tape library. Media type may be specified by any of the following:
- Input TDSI—specified in field LCSMMED.
- Default entry data class—this value is used only if no TDSI media type was
specified.
- Cartridge entry installation exit (CBRUXENT)—may provide the media
type if it is not specified in TDSI or default entry data class, or may
override the value specified. If the installation exit is invoked and returns
an invalid media type, cartridge entry processing is discontinued.
If media type is not available from any of the sources listed above, the
volume is not entered into the MTL.
– Compaction type specified in TDSI is ignored, and the UNKNOWN value is
passed to the installation exit. The exit may specify a value for compaction
type.
– Special attribute specified in TDSI is ignored and a value of NONE is passed
to the installation exit. The exit may specify a value for special attribute.
EXITINFO=installation-exit-information
Specifies the name of a character variable (16-byte length) that contains a
customer-specified free-form value that is passed to the cartridge entry
installation exit (CBRUXENT).
The permanent OAM control block structure must be available in order for manual
cartridge entry to be performed. This means that the OAM address space must
have been started since the last IPL.
When manual cartridge entry is successful, the following processing occurs:
v The tape volume record is either created or updated in the TCDB.
Chapter 6. Library Control System (LCS) External Services
159
v TDSI for the volume is returned in LCSMTDSI in structure LCSMLIST.
v The scratch volume counts in the library record in the TCDB are updated.
v Message CBR3610I is issued to inform the operator of the volumes which have
been entered into the library.
If the cartridge entry installation exit (CBRUXENT) is disabled, cartridge entry
processing is not performed. Unless the installation has indicated that the cartridge
entry installation exit should not be called, it is invoked for every volume in the
list.
Even though the manual tape library supports national characters (@ $ and #) and
special characters (, . / ' ( ) * & + − and =), for coexistence, the volume serial
number for each of the volumes entered into a manual tape library should meet
the same character set defined for an ATLDS: upper case alphabetics or numerics.
The volume serial may not contain any imbedded blanks.
The volume serial for each volume entered into a manual tape library may not be
a duplicate of a known DASD volume, or a tape volume which resides in another
tape library dataserver (according to the tape volume record in the TCDB).
If a volume record exists for a private volume and it contains a nonblank storage
group name, the storage group name is validated. If the storage group is not
“tape”, is not defined to the active SMS configuration, or does not contain the
library specified for the MCE request, the request fails and the volume is not
entered into the library.
If a volume record exists in the TCDB for an MCE volume and the volume record
indicates that the volume already resides in the specified library the entry for this
volume fails (duplicate assumed).
If an error is encountered while processing one of the volumes, the return and
reason codes for that volume are stored in the fields LCSMRET and LCSMREAS in
the volume list array, and processing continues for the rest of the volumes. If an
error occurs which causes cartridge entry to be disabled or suspended, no more
volumes are processed and error return and reason codes are set for the remaining
volumes in the list.
If a volume record exists for the volume entered into the manual tape library, tape
device selection information is processed as shown in Table 6.

When a value is requested, the keyword operand might be either the name of the
field that contains the requested value, or the number, in parentheses, of a general
register in the range of 2 through 12 that contains the address of the field.
Parameter Descriptions
TYPE=TAPE
Specifies a request related to the TCDB.
FUNC=EJECT
Specifies a request to eject or query the eject status of a tape volume from a
tape library.
VOLUME=volume-serial-number
Specifies the name of a character variable (six-byte length) that contains the
volume serial number of the volume to be ejected. The volume serial number
must be left justified in the field and padded on the right with blanks.
EJECTOPT=KEEP
Specifies that the TCDB record for the tape volume being ejected should not be
deleted after the eject completes successfully.
EJECTOPT=PURGE
Specifies that the TCDB record for the tape volume being ejected should be
deleted after the eject completes successfully.
If the EJECTOPT parameter is specified on the macro invocation, the cartridge
eject installation exit may override it.
If the EJECTOPT parameter value is not specified on the macro invocation, the
eject default is used. (This default is established when the library is defined by
the storage administrator using the ISMF library define panel.) However, the
cartridge eject installation exit (CBRUXEJC) may ultimately override the value.
EJECTOPT=QUERY
Specifies a request to query the OAM internal work queues to determine if an
eject request is pending. CBRXLCS FUNC=QVR should be invoked first to
determine if an eject request is pending at the library or if the eject request has
completed. If the status of the eject request from the QVR function cannot be
determined, you can use this option to determine if the eject request resides on
an OAM internal queue but might not have been sent to the library yet.
BULKEJCT=YES
Specifies that the ejected cartridge be placed in the high-capacity output station
of an ATLDS. If this parameter is not specified or the high-capacity output
Chapter 6. Library Control System (LCS) External Services
163
station is not configured, the cartridge is placed in the convenience output
station. If a convenience station is not installed in a 3494, the cartridge is
placed in the single cell output area.
BULKEJCT=NO
Specifies that the cartridge be placed in the convenience output station of an
ATLDS. This is the default.
Note: For a manual tape library, BULKEJCT is ignored.
EXITINFO=installation-exit-information
Specifies the name of a character variable (16-byte length) that contains a
customer specified free-form value that is passed to the cartridge eject
installation exit (CBRUXEJC).
USERID=userid
Specifies the name of a character variable (8-byte length) that contains a TSO
user ID. The field must be left-justified and padded on the right with blanks.
After the eject request is successfully scheduled (a zero return and reason code
from the CBRXLCS macro invocation), eject completion or failure messages are
sent to this user ID through the system services SEND interface.
Successful EJECT Processing
When the EJECT completes successfully, the following processing occurs:
v The requested volume is ejected from the library.
For an ATLDS, the volume is placed in an output station of the library. The
volume record is deleted from the library manager inventory. For an MTL
volume, it is the responsibility of the operator to move the logically ejected
volume to an appropriate shelf location. An eject completion message is sent to
the optional TSO user ID specified on the macro invocation and to an MVS
console.
v The TCDB record for the volume is either kept or purged, as stipulated by one
of the following:
– The installation exit
– The parameter specified on the macro invocation
– The default disposition defined for all volumes in the library
v If the TCDB record is kept, it is updated to note that the volume is no longer in
the library.
v When the EJECT of a volume is not successfully scheduled through the
CBRXLCS macro invocation, the error messages are sent to the system log to
provide an audit trail.
To have the cartridge eject installation exit (CBRUXEJC) notified when an eject
request fails, see “Failed Eject Notification Processing” on page 234.
Return and Reason Codes for CBRXLCS Eject
The return code is placed in register 15 and in the LCSPL in field LCSRCODE. The
reason code is placed in register 0 and in the LCSPL in field LCSREAS.
Note: A zero return code and zero reason code from the CBRXLCS EJECT function
do not indicate that the cartridge has been ejected; however, they do indicate
that the CBRXLCS EJECT function was successful in scheduling the request
into the OAM address space for later processing. When the eject request is
later processed, the OAM address space relays the success or failure of the
eject through the issuance of messages.

Querying the Residence of a Volume
The Query Volume Residence (QVR) function allows you to determine the tape
library in which a specified volume resides. If VOLINFO=YES is specified, the
returned information is mapped by the CBRTVI macro. See “Tape Volume
Information (CBRTVI Macro)” on page 201 for more information on this macro.
Figure 8 provides the CBRXLCS Assembler macro syntax that is used to perform
the query volume residence function:

166
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Parameter Descriptions
TYPE=TAPE
Specifies a request related to the TCDB.
FUNC=QVR
Specifies a request to return the name and type of library in which the given
volume is resident.
VOLUME=volume-serial-number
Specifies the name of a character variable (six-byte length) that contains the
volume serial number of the volume whose residence is to be determined. The
volume serial number must be left justified in the field and padded on the
right with blanks.
LIBNAME=library-name
Specifies the name of a character variable (eight-byte length), that contains the
name of the library where the volume is expected to reside. The library name
must be left justified in the field and padded on the right with blanks.
If the volume has no volume record in the TCDB, QVR checks for the volume
in the specified library. If the volume has a record in the TCDB, QVR validates
that the specified library and the library indicated on the volume record match.
It also checks to see the whether the volume physically resides in the library
specified by this parameter.
Note: A library name of SHELF is considered invalid. The SHELF library name
is reserved for shelf-resident volumes.
TCDBCHK=YES | NO
If this optional parameter is omitted or YES is specified, the QVR function
attempts to retrieve the specified volume's TCDB record. TCDBCHK=YES is
the default.
If this optional parameter is specified and NO is specified, the QVR function
does not retrieve the specified volume's TCDB record from the catalog and
only makes the call to the library manager of the specified library. With
VOLINFO=YES specified, the TVI will contain only information from the
library manager inventory of the library specified.
If LIBNAME is not specified, this keyword is ignored.
VOLINFO=YES | NO
Specification of VOLINFO=YES requests that QVR return the information that
is available about the volume from both the volume record in the TCDB and
the library manager inventory. The returned information is mapped by the
CBRTVI mapping macro.
SUBPOOL=spno
Specifies the name of a bit variable (1-byte length) that contains the number of
the subpool from which storage for the volume information is obtained. If no
subpool is specified, storage is obtained from subpool 0 in the key of the caller.
This keyword is only used when VOLINFO=YES is specified, and is otherwise
ignored.
LOC=ANY | BELOW
ANY specifies that the storage for the requested information may be obtained
above the 16-megabyte line. BELOW specifies that the storage for the
requested information is to be obtained below the 16-megabyte line. BELOW is
the default if the LOC keyword is omitted. The LOC option is ignored if
STORADDR is specified.
Chapter 6. Library Control System (LCS) External Services
167
STORADDR=TVI-storage-address
Specifies a 4-byte address for LCS External Services to use when returning tape
volume information; this information is mapped by the CBRTVI macro. The
CBRTVI macro validates TVI header information for the storage specified by
STORADDR, as follows:
v The value for TVIID must be TVI.
v The value for TVILENG must be at least as large as the TVI mapping macro
length currently supported by LCS External Services.
The STORADDR keyword is ignored unless you specify VOLINFO=YES on
the QVR function. Specifying STORADDR on subsequent invocations allows
you to reuse the TVI storage that was obtained by LCS External Services on
the initial QVR invocation. Specifying the LCSTVI@ address as the
STORADDR value enables the storage to be reused, reducing the number of
storage requests that are required for multiple QVR invocations.
Recommendation: On the initial invocation of the QVR function, where
VOLINFO=YES is specified, allow LCS External Services to obtain the TVI
storage. This ensures that the proper CBRTVI mapping macro length is
obtained. (This length may change with future enhancements.) On subsequent
QVR invocations, you can then specify the TVI address returned on the initial
invocation (LCSTVI@) as the STORADDR value, thereby reusing the storage.
The TVILENG value returned on the initial invocation is the appropriate value
for freeing this storage when all QVR invocations are complete.
Successful Query Volume Residence Processing
When the query volume residence function is successful and the volume resides in
a library, the following fields in the LCSPL (Figure 15 on page 187) are updated:
v The name of library in which the volume resides is returned in field LCSLIBNM.
This may be the library name found in the volume record or the library name
specified in the QVR invocation. TVILIBNM contains the library name stored in
the TCDB for comparison.
v If the library is an ATLDS, the flag LCSATL is turned on.
v If the library is an MTL, the flag LCSMTL is turned on.
v If a console name has been specified for the library, it is returned in
LCSCONSN. Otherwise, LCSCONSN is set to blanks.
v If VOLINFO=YES was specified, LCSTVI@ contains the address of the requested
volume information. The information is mapped by macro CBRTVI (see
Figure 17 on page 201 for details).
Note: The caller must free the storage obtained for the tape volume information.
To ensure that the correct amount of storage is freed, use the TVILENG
field in the TVI header section to free this storage.
Return and Reason Codes for CBRXLCS Query Volume Residence
The return code is placed in register 15 and in the LCSPL in field LCSRCODE. The
reason code is placed in register 0 and in the LCSPL in field LCSREAS.
Table 11 on page 169 provides the reason codes associated with each of the return

Required Parameters
TYPE=TAPE
Specifies a request related to the TCDB.
FUNC=EXPORT
Specifies a request to initiate (or cancel) the export of logical volume from a
library.
VOLUME=volume-serial-number
Specifies the name of a character variable (six-byte length) that contains the
logical volume serial number of the export list volume to be used for this
export operation.
Optional Parameters
CANCEL=YES | NO
CANCEL=YES specifies that the export request currently executing in the
library where the specified volume resides be canceled.
CANCEL=NO, or no specification for this optional parameter, indicates that
the export request of the logical volume from a library be processed.
Notes on Export Processing
The export function requires that OAM is active, that the library for the export
operation is online and operational, and that the cartridge eject installation exit
(CBRUXEJC) is not disabled. This environment is necessary for the exported logical
volumes to go through completion processing and for the stacked volumes
containing the logical volumes to be ejected. Also, only one export operation can
be active in a library (VTS) at a time, and an export and import operation are not
allowed to execute simultaneously in the same library (VTS).

Figure 11. CBRXLCS IMPORT Assembler Macro Syntax
Required Parameters
TYPE=TAPE
Specifies a request related to the TCDB.
FUNC=IMPORT
Specifies a request to initiate (or cancel) the import of a logical volume into a
VTS.
VOLUME=volume-serial-number
Specifies the name of a character variable (six-byte length) that contains the
logical volume serial number of the import list volume to be used for this
import operation.
Optional Parameters
CANCEL=YES | NO
CANCEL=YES specifies that the import request currently executing in the
library where the specified volume resides be canceled.
CANCEL=NO, or no specification for this optional parameter, indicates that
the import request of the logical volume into a VTS be processed.
Notes on Import Processing
The import function requires that OAM is active, that the library for the import
operation is online and operational, and that the cartridge entry installation exit
(CBRUXENT) is not disabled. This environment is necessary for the imported
logical volumes to go through entry processing. An import operation is more
restrictive than an export operation in that only one import operation is allowed
per physical library, while one export operation is allowed per logical library
(VTS). Also, import and export operations are not allowed to execute
simultaneously in the same library (VTS).
Return Codes for CBRXLCS IMPORT
The return code is placed in register 15 and in the LCSPL in field LCSRCODE. The
reason code is placed in register 0 and in the LCSPL in field LCSREAS.

Changing Library Operating Modes (Peer-to-Peer VTS Mode
Control)
The Peer-to-Peer VTS mode control (PTPMC) function allows an installation or
application, such as Geographically Dispersed Parallel Sysplex (GDPS), to change
current operating modes of the library. Upon installation of the library, the
customer engineer must determine the default mode settings. (See “Geographically
Dispersed Parallel Sysplex Support for Peer-to-Peer VTS” on page 21 for more
information on GDPS.)
Attention: In a library with outboard policy management support, the selective
peer-to-peer copy mode overrides PTPMC settings. See “Selective Peer-to-Peer
Copy Mode” on page 23 for further information on the selective peer-to-peer copy
mode.
Figure 12 provides the CBRXLCS Assembler macro syntax that is used to perform
the PTPMC function.

When a value is requested, the keyword operand may be one of the following:
v The name of the field that contains the requested value
v The number, in parentheses, of a general register in the range of 2–12 that
contains the address of the field
Required Parameters
TYPE=TAPE
Specifies a request related to the TCDB.
FUNC=PTPMC
Specifies a request to change current mode settings of the Peer-to-Peer VTS
library.
LIBNAME=library-name
Specifies the name of a character variable (eight-byte length) that contains the
fully-specified library name. The library name must be left justified in the field
and padded on the right with blanks. Unless explicitly specified with the
parameter, the library name specified can be either a distributed library or a
composite library.
Optional Parameters
At least one of the following optional keywords must be specified with the
function PTPMC:
v ACCESS
v COPYMODE
v COPYOPER
v IOLIB
Chapter 6. Library Control System (LCS) External Services
177
If an optional keyword is not specified, the current setting for that option is
retained. The operational modes specified are applied to all IBM TotalStorage
Virtual Tape Controllers (AX0).
IOLIB=PRIMARY
Specifies a request to set the distributed library that is to be selected for all
host I/O operations; this makes the selected library the master library. During
mount processing, if the primary VTS is not available, the mount request is
failed. If the VTS does not have a valid version of the volume, and a valid
version is available on another VTS, a copy operation is performed as part of
the mount process. If a valid version cannot be copied, the mount is failed. If
the specified VTS does not have the needed volume in cache, and it is in cache
in another VTS, a copy operation is also performed. If the needed volume is
not in cache in any available VTS, a recall is performed on the specified VTS.
The library specified for LIBNAME must be a distributed library.
Note: If you are setting IOLIB=PRIMARY and the specified distributed library
is not currently the master library, the completion of this request can
take up to 20 minutes.
IOLIB=PREFERRED
Specifies a request to set the preferred distributed library for host I/O
operations. The preferencing is honored as long as the VTS library specified is
available and has a valid version of the volume in its cache, and as long as
another available VTS does not have the volume in its cache. The library
specified for LIBNAME must be a distributed library.
IOLIB=BALANCED
Specifies a request to let the library balance the workload across all the VTS
libraries in the Peer-to-Peer VTS configuration. The balance of the workload is
the primary criterion for selection of the VTS to perform host I/O operations.
IOLIB=DEFAULT
Specifies a request to use the customer engineer's default I/O selection setting
on the AX0s for host I/O operations.
COPYMODE=IMMEDIATE
Specifies a request to set the copy mode to IMMEDIATE. With this setting, a
copy of the data is made upon receiving the host rewind/unload (RUN)
command. The completion of the rewind/unload (RUN) command is held
until the copy has been made.
COPYMODE=DEFERRED
Specifies a request to set the copy mode to DEFERRED. With this setting,
upon receiving the host rewind/unload (RUN) command, the copying of the
data is queued.
COPYMODE=DEFAULT
Specifies a request to use the customer engineer's copy mode setting and the
customer engineer's deferred mode priority threshold value on the AX0s.
DEFVALUE=deferred-priority-threshold
Specifies the name of a bit variable (1-byte length) that contains the number of
hours between 0 and 255 for the deferred copy mode priority threshold value.
If a copy operation has been queued longer than the number of hours specified
by the deferred copy mode priority threshold value, when it is selected for
processing, it is given a higher I/O priority than host I/O operations. This
specified parameter value affects copy operations that are initiated after the
successful completion of this command.
178
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
This parameter is only applicable with the COPYMODE=DEFERRED
specification and is ignored with any other FUNC=PTPMC specification. If
COPYMODE=DEFERRED is specified without this parameter, the current
deferred mode priority threshold value is retained.
COPYOPER=ENABLE
Specifies a request to enable copy operations that have been previously
disabled.
COPYOPER=DISABLE
Specifies a request to disable copy operations. Copies currently in progress are
completed. Subsequent copies are queued to be performed later when copy
operations are enabled again.
ACCESS=RWDISCON
Specifies a request to enable the access mode of Read/Write Disconnected, a
special mode that allows controlled access to data when one or more elements
of a PTP VTS become unavailable and prevent normal operations. The
Read/Write Disconnected mode allows logical volumes to be read, modified,
or rewritten, unless the volumes are known to be invalid. This mode forces the
available VTS to become the master; it should only be set for one VTS. This
mode is no longer in effect when communication with both VTSs has been
established and token updates have been completed.
The library specified for LIBNAME must be a distributed library. IOLIB,
COPYMODE, and COPYOPER specifications are ignored at the library when
the ACCESS keyword is specified.
Note: Check with your hardware support center for the availability of the
Read/Write Disconnected option through this interface. If the installed
microcode does not support this option, it will be ignored.

Obtaining Operational Mode Settings (Peer-to-Peer VTS Data)
The Peer-to-Peer VTS data (PTPDATA) function allows an installation or
application, such as Geographically Dispersed Parallel Sysplex (GDPS), to obtain
operational mode settings and device-related information from the PTP VTS
library. (See “Geographically Dispersed Parallel Sysplex Support for Peer-to-Peer
VTS” on page 21 for more information on GDPS.)

Specifies a request for Peer-to-Peer VTS library device information. The
information is returned in mapping macro CBRTDI pointed to by LCSTDI@ in
the LCSPL output parameter of the CBRLCSPL mapping macro.
Optional Parameters
SUBPOOL=subpool-number
Specifies the name of a bit variable (1-byte length) that contains the number of
the subpool from which storage for the requested information is obtained. If no
subpool is specified, storage is obtained from subpool 0 in the key of the caller.
LOC=BELOW | ANY
BELOW specifies that the storage for the requested information is to be
obtained below the 16-megabyte line. ANY specifies that the storage for the
requested information may be obtained above the 16-megabyte line. ANY is
the default value if the LOC keyword is omitted.
Notes:
1. The VTS I/O distributed libraries are identified as 1 or 2 in the returned
CBRTDI data; however, the TotalStorage Peer-to-Peer VTS Specialist identifies
the distributed libraries as 0 and 1. Use the library name or sequence number,
or both, that are displayed in the TotalStorage Peer-to-Peer VTS Specialist to
ensure that the correct distributed library is being referenced.
2. The caller must free the storage obtained for the returned data information,
pointed to by LCSTDI@, for the length specified in the TDILENG field in the
CBRTDI mapping macro.

CBRXLCS Macro Interface
The executable CBRXLCS macro invokes functions that are provided by LCS
External Services. This section describes how to use the CBRXLCS macro, the
CBRXLCS return and reason codes, and the CBRXLCS parameter list.
Using the CBRXLCS Macro in an Assembler Environment
Perform the following steps to use the CBRXLCS macro in an Assembler language
environment:
__ Step 1. Include mapping macro CBRLCSPL to provide a DSECT for the LCS
External Services parameter list, as follows:
CBRLCSPL
__ Step 2. Create copies of the LCSPL in both static and dynamic storage using
the LIST form of CBRXLCS, as follows:
CBRXLCS
CBRXLCS
MF=(L,static-list-name)
MF=(L,dynamic-list-name)
Note: No other keywords can be supplied on the LIST form of
CBRXLCS.
184
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
__ Step 3. Initialize the LCSPL by copying the static LIST form to the dynamic
LIST form.
Rule: Because the length of the LCSPL exceeds 256 bytes, you must use
the MVCL instruction for the copy.
__ Step 4. Set parameter values in the LCSPL using the MODIFY form of
CBRXLCS, as follows:
CBRXLCS keywords,
MF =(M,dynamic-list-name)
Rule: If you use the MODIFY form of the macro, you must follow it
with the EXECUTE form.
__ Step 5. Set the parameter values in the LCSPL using the EXECUTE form of
CBRXLCS and invoke LCS External Services to perform the requested
function, as follows:
CBRXLCS keywords,
MF=(E,dynamic-list-name)
Note: You can use the EXECUTE form of the macro without having
previously used the MODIFY form.
__ Step 6. To check the completeness and compatibility of the set of parameters
supplied on a single invocation of CBRXLCS, specify one of the
following statements using the MODIFY form of the macro or the
EXECUTE form of the macro, as follows:
CBRXLCS keywords,
MF=(M,dynamic-list-name,COMPLETE)
or
CBRXLCS keywords,
MF=(E,dynamic-list-name,COMPLETE)
There is no standard form of the CBRXLCS macro for Assembler language.
CBRXLCS Return Codes
The return code from CBRXLCS is placed in register 15 and in the LCSPL in field
LCSRCODE. The corresponding reason code is placed in register 0 and in the
LCSPL in field LCSREAS.
Note: See the description of each CBRXLCS function for specific return and reason
code pairs.

185
See the “CBRXLCS REASON CODES” area in Figure 15 on page 187 for a specific
description of XLCS reason codes. Topic CBRXLCS Return and Reason Codes in
z/OS DFSMSdfp Diagnosis, GY27-7618 also contains descriptions of XLCS return
and reason codes.
CBRXLCS Execution Environment
The following execution environment is required for use by the CBRXLCS macro:
v Task mode
v Unlocked
v Noncross-memory mode (HASN = PASN = SASN)
v 24-bit or 31-bit addressing mode
v Primary ASC mode (not AR mode)
v You must also have TESTAUTH authorization.
LCS External Services Parameter List (CBRLCSPL Macro)
The LCS External Services Parameter List (LCSPL), mapped by macro CBRLCSPL,
is used to pass parameters to the LCS External Services, and to pass return and
reason codes and other information back to the caller.
The storage for the LCSPL must be aligned to a fullword boundary. If this is not
the case, an error is returned and the requested function is not performed.
Figure 15 on page 187 provides the format of the LCS External Services parameter
list. The boldfaced lines of code are new for this release.
Rule: Fields that are identified as RESERVED FOR IBM FUTURE OR INTERNAL
USE must not be used by the installation.

Tape Data Information (CBRTDI Macro)
Tape data information (TDI), mapped by macro CBRTDI, is used to pass
information about the composite Peer-to-Peer VTS library that is specified on the
CBRXLCS PTPDATA request. Depending on the PTPDATA request, either the
library's operating mode information or the library's device information is returned
in TDI. Figure 16 gives the format for the tape device information.

Chapter 7. Installation Exits
The following material provides information for creating your own installation exit
routines. For examples of SAMPLIB jobs pertaining to these installation exits, see
Appendix A, “SAMPLIB Members,” on page 255.
Each of the installation exits (CBRUXENT, CBRUXEJC, CBRUXCUA, and
CBRUXVNL) are linked to (on each invocation) using the MVS LINK macro and
must reside in a library in the LNKLST concatenation. Because the exits are called
(on each invocation) using the MVS LINK macro, a new copy of the exit can be
LINKEDITED on the system at any point in time and OAM will pick up the new
version. However, if the exit had been previously disabled or return code 16 had
been used to bypass the exit, to re-enable the exit, you must also restart OAM or
issue the LIBRARY RESET command.
Change Use Attribute Installation Exit (CBRUXCUA)
When you issue the CBRXLCS macro FUNC=CUA, the ISMF ALTER line operator
from the mountable tape volume list, or the LIBRARY LMPOLICY command, the
Change Use Attribute installation exit (CBRUXCUA) is called before the volume
record is changed.
This installation exit is designed to allow the installation the opportunity to
approve or disapprove the proposed change to the volume’s use attribute, and to
view, and if necessary, to change many fields in the TCDB volume record as well
as outboard policy fields, if applicable. Approval or disapproval is communicated
by way of the return code which is passed back in register 15. Volume record fields
are updated by changing the appropriate fields in the change use attribute
installation exit parameter list (CBRUXCPL).
The change use attribute installation exit is supplied by DFSMSrmm. If your
installation is not using DFSMSrmm, the supplied exit returns a return code of 16,
indicating that the installation exit not be invoked again. For more information, see
z/OS DFSMSrmm Managing and Using Removable Media, z/OS DFSMSrmm
Implementation and Customization Guide, and z/OS DFSMSrmm Diagnosis Guide.
If your installation is not using DFSMSrmm and your tape management vendor
has not supplied an exit, OAM provides a sample change use attribute exit
(CBRSPUXC) in SAMPLIB that can be customized to fit your needs. The discussion
that follows will assist in determining whether the exit is needed on your system.
For more information on this SAMPLIB member, see “SAMPLIB Member
CBRSPUXC” on page 271.
If the caller of the CBRXLCS macro specified EXITINFO on the macro invocation,
the 16 bytes of free-form information provided on the invocation are passed to the
exit. If the CBRXLCS invocation is called during job processing for a scratch
volume, SMS TVRU S->P is passed to the exit. If EXITINFO is not specified on the
CBRXLCS invocation, the field in the exit parameter list contains binary zeros.
The following library-related information is passed to the exit but may not be
updated by the installation:
v Library name
v Library device type
© Copyright IBM Corp. 1993, 2010
211
v
v
v
v
Library
Library
Library
Library
logical type
description
console name (if specified) or blanks
supported function indicator
If the volume is not library-resident, the exit parameter list indicates a library
name of SHELF and all the other library fields in the exit parameter list are blank.
Both the current use attribute as it is recorded in the tape volume record and the
new use attribute are passed to the exit as input variables.
On a change to SCRATCH, the fields that are passed to the exit represent the
values in the tape volume record as it currently exists in the TCDB before any
changes are made. If a volume is being changed from PRIVATE to SCRATCH, and
if the installation exit supplies new values for any of the following fields, they are
ignored. The following default scratch values are set before committing the
changes to the TCDB:
v Volume use attribute = S
v Storage group name = *SCRTCH*
v Write protection status = N
v Checkpoint volume indicator = N
v Volume expiration date = blank
v Tape device selection values:
– Recording technology is unchanged
– Media type is unchanged
– Compaction indicator is unchanged
– Special attribute is set to none
v If the library supports outboard policy management, default construct names
(blanks) are passed to the library.
On a change to PRIVATE, the fields that are passed to the exit represent the values
in the volume record as updated with the parameters specified on the CBRXLCS
macro invocation. The installation may override some of those parameters as
described in the table below. If the installation makes no changes, the values are
committed to the TCDB as presented in CBRUXCPL. If the exit changes some
fields, they are processed as described below.
If a field is described as ‘input only’ in the table below, it may not be updated by
the installation. If it is described as ‘output’, it may be updated by the installation.
If it is further described as ‘verified’, the contents or format of the field is validated
before updating the TCDB volume record with information from the installation.
For a change to PRIVATE or SCRATCH for a physical WORM tape volume, the
UXCVWORM indicator is set on. For a logical WORM tape volume, this indicator
is not turned on. Since a logical WORM volume is not distinguishable by a unique
media type, the UXCVWORM indicator is not turned on for a logical WORM
volume. If this information is needed, the CBRUXCUA installation exit can invoke
the CBRXLCS FUNC=QVR interface to obtain this information from the library.

|
|
|
|
|
If the installation exit returns with an invalid value in a parameter field, returns
with an invalid return code, or abnormally terminates, the current request fails. In
addition, change use attribute processing for subsequent PRIVATE to SCRATCH
requests is disabled and the change use attribute exit is not called again until
either OAM is stopped and started, or the LIBRARY RESET,CBRUXCUA operator
command is issued.
212
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Note: When an error occurs in the installation exit, PRIVATE to SCRATCH
requests are disabled in order to prevent the inadvertent assignment of a
private volume to scratch status. Processing continues for
SCRATCH-to-PRIVATE, SCRATCH-to-SCRATCH, and PRIVATE-to-PRIVATE
requests without invocation of the change use attribute installation exit.
Table 19 on page 214 lists the parameters that are passed to the exit. The fields may
or may not be updated by the installation, depending on the function being
performed (for example, changed to SCRATCH or PRIVATE).

If a field is described as verified, the following values are checked for validity upon
return from the exit:
Storage Group Name
When a volume is changed from scratch to private or private to private, the
storage group name that is supplied may be blanks. If a nonblank value is
supplied, the name must be defined in the active SMS configuration as a
tape storage group. In addition, if the volume is library-resident, the
library must be defined to that storage group.
Storage Class Name
When a volume is changed from scratch to private or private to private, the
storage class name that is supplied may be blank. If a nonblank value is
supplied, the name must only conform to Storage Management Subsystem
(SMS) naming conventions standards. See “Syntax Rules” on page 215 for
the syntax checking that is performed.
Data Class Name
When a volume is changed from scratch to private or private to private, the
data class name that is supplied may be blank. If a nonblank value is
supplied, the name must only conform to Storage Management Subsystem
(SMS) naming conventions standards. See “Syntax Rules” on page 215 for
the syntax checking that is performed.
214
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Management Class Name
When a volume is changed from scratch to private or private to private, the
management class name that is supplied may be blank. If a nonblank value
is supplied, the name must only conform to Storage Management
Subsystem (SMS) naming conventions standards. See “Syntax Rules” for
the syntax checking that is performed.
Syntax Rules: The values that you specify for the storage group, storage class, data
class, and management class construct (policy) names must meet the following
SMS naming convention standards:
v Alphanumeric and national characters only
v Name must begin with an alphabetic or national character ($*@#%)
v No leading or embedded blanks
v Eight characters or less
Write protection status
Y, N, or blank can be specified.
Checkpoint volume indicator
Y, N, or blank can be specified.
Last mounted date
The date specified must be in ISO format (YYYY-MM-DD) or blanks.
Last written date
The date specified must be in ISO format (YYYY-MM-DD) or blanks.
Volume expiration date
The date specified must be in ISO format (YYYY-MM-DD) or blanks.
Outboard Policy Management Considerations
The UXCLOPM indicator in the CBRUXCPL parameter list is set on when the
library in which the volume resides supports outboard policy management,
notifying the CBRUXCUA installation exit of this capability.
The CUA GETPOLICY option requests that the volume’s policy names be retrieved
from the library and passed to the CBRUXCUA installation exit in the
UXCLMOPM fields of the CBRUXCPL parameter list. The UXCVLOPM indicator
indicates that UXCLMOPM fields contain the constructs that are retrieved from the
library. The exit can change the UXCLMOPM values for the storage class
(UXCLMSC), management class (UXCLMMC), and data class (UXCLMDC) fields.
These values then set the volume outboard policy names in the library in which
the volume resides. If you set the storage group policy value in the UXCGROUP
field, this value is updated in the TCDB and at the library.
If the GETPOLICY option is specified on the CUA invocation for a scratch volume,
it is ignored. The GETPOLICY option is only honored for PRIVATE-to-PRIVATE
CUA requests for a volume that resides in a library that supports outboard policy
management.
Chapter 7. Installation Exits
215
If the SCNAME, MCNAME, DCNAME, or GRPNAME option, or all, are specified
on the CUA invocation, the UXCVCOPM indicator notifies the exit that one or
more of the UXCLMOPM fields has a value that changes the volume’s outboard
policy names. If the request is to change the storage group name, both the
UXCLMSG and the UXCGROUP fields contain the new value. If GRPNAME is not
specified, the UXCGROUP field contains the TCDB storage group and the
UXCLMSG field contains binary zeros. The installation exit can change the policy
field values.
THE CBRUXCUA installation exit can invoke the QVR function to retrieve the
existing library policy names for a volume for comparison of existing policy names
to the requested policy names. For more information about the QVR function, see
“Query Volume Residence (QVR)” on page 148.
If CUA is invoked with a policy change request and the policy field value is all
blanks, the request is to set the policy name to the default policy. If a policy is not
being changed, the UXCPL policy field is initialized to binary zeros indicating the
current policy name, whether the default or a specific policy name is being
retained.
If you do not specify a policy keyword, the UXCLMOPM fields contain binary
zeros. The CBRUXCUA installation exit can assign construct values in the
input/output fields (UXCLMMC, UXCLMSC, and UXCLMDC). The storage group
name can only be specified in the UXCGROUP field.
Job Processing Considerations
If the library supports outboard policy management and if the CUA invocation is
for job processing of a scratch volume, UXCJOBP is set on and the UXCEXITI field
contains SMS TVRU S->P. Changes to UXCGROUP, UXCLMSC, UXCLMMC, and
UXCLMDC are ignored. UXCJOBP indicates that the storage group and other
policy names are already set at the library and cannot be changed by the exit at
this time.
If the volume resides in a library that does not support outboard policy
management, the storage group can be changed even if the UXCEXITI field
contains SMS TVRU S->P. In this case, the UXCLOPM and UXCJOBP indicators are
off.
Change Use Attribute Installation Exit Parameter List
(CBRUXCPL)
The change use attribute installation exit (CBRUXCUA) is passed by way of
register 1, the pointer to a parameter list mapped by CBRUXCPL. Figure 19 on
page 217 provides the format of CBRUXCPL.

16
Do not call the change use attribute installation exit again. Change the use
attribute of the volume as requested using the existing volume record
information.
Note: If the installation has returned return code 16 indicating that the exit should
not be called again, the exit can be reactivated either by stopping and
restarting OAM or issuing the LIBRARY RESET,CBRUXCUA command. If
the exit abnormally terminates, passes back an invalid return code, or passes
back invalid data, PRIVATE to SCRATCH change use attribute processing is
discontinued until one of the above actions has been taken. This is intended
to protect user data from being inadvertently scratched.
Change Use Attribute Installation Exit (CBRUXCUA) Usage
Requirements
The change use attribute installation exit must reside in load module CBRUXCUA.
It is invoked by way of the MVS LINK macro and must reside in a library in the
LNKLST concatenation. The installation exit can be executed above or below the
16-megabyte line. The installation exit must be coded and link-edited on the
system as re-entrant.
Under some circumstances, CBRUXCUA may be invoked in a key other than the
job key. Therefore, all storage dynamically acquired by CBRUXCUA should be
obtained from subpool 227, 228, 229, 230, 231, or 241, in order to ensure that it is
accessible in the program status word (PSW) key.
The following characteristics describe the execution environment in which the
change use attribute installation exit is invoked:
v Task mode
v Unlocked
v Noncross memory mode (HASN = PASN = SASN)
v The addressing mode specified when the exit was linkage edited
v Primary ASC mode (not AR mode)
v User key, supervisor state
Mapping macro CBRUXCPL must be included by the installation exit.
Cartridge Entry Installation Exit (CBRUXENT)
This installation exit is called to approve or disapprove entry of a cartridge into a
library and to determine TCDB volume record contents for each volume that is
entered into a library. If the library supports outboard policy management, the
installation exit can also obtain and set outboard policy names.
Chapter 7. Installation Exits
221
The cartridge entry installation exit is supplied by DFSMSrmm. If your installation
is not using DFSMSrmm, the supplied exit returns a return code of 16, indicating
that the installation exit not be invoked again. For more information, see z/OS
DFSMSrmm Managing and Using Removable Media, z/OS DFSMSrmm Implementation
and Customization Guide, and z/OS DFSMSrmm Diagnosis Guide.
If your installation is not using DFSMSrmm and your tape management vendor
has not supplied an exit, OAM provides a sample cartridge entry installation exit
(CBRSPUXE) in SAMPLIB that can be customized to fit your needs. The discussion
that follows will assist in determining whether the exit is needed on your system.
For more information on this SAMPLIB member, see “SAMPLIB Member
CBRSPUXE” on page 278.
The following library-related information is passed to the exit. None of the
library-related information can be modified by the exit.
v Library name
v Library device type
v Library console name
v Library logical type
v Library description
v Library support indicator

The fields that are not marked as input only may be modified by the exit. If it is
described as output, it may be updated by the installation. If it is further described
as verified, the contents or format of the field is checked for validity before
updating the TCDB volume record with information from the installation and, if
applicable, updating the library with the changed outboard policy names. Date
fields are in ISO format (YYYY-MM-DD).
For a previously unknown volume (no volume record exists), the volume serial
number, the default volume use attribute, and the default tape device selection
information are passed to the exit. The default volume use attribute is set by the
storage administrator using the ISMF library define panel. The default tape device
selection information (TDSI) is derived from the default entry data class, which is
also set by the storage administrator using the ISMF library define panel. The
default TDSI information is set as follows:
1. The library vision system determines the media type when the cartridge is
entered. OAM uses this information to set the TDSI media type.
2. If a default entry data class is supplied in the library definition, the TDSI
recording technology is set from the data class.
3. For media type MEDIA1, OAM sets 36-track recording technology if the default
volume use attribute is PRIVATE and no recording technology is specified.
4. For media type MEDIA2, OAM always sets 36-track recording technology.
5. For media types MEDIA3 and MEDIA4, OAM sets 128-track recording
technology if the default volume use attribute is PRIVATE and no recording
technology is specified.
6. For MEDIA5, MEDIA6, MEDIA7, and MEDIA8, OAM sets EFMT1 recording
technology if the default volume use attribute is PRIVATE and no recording
technology is specified.
7. For MEDIA9 and MEDIA10, OAM always sets EFMT2 recording technology if
the default volume use attribute is PRIVATE and no recording technology is
specified.
The remaining volume-related values are set to blanks. A volume record creation
date of blanks indicates that the TCDB volume record does not exist.
For a known volume, whatever information existed in the volume record at the
time the cartridge was entered is passed to the exit.
The UXEVATTR field can be used to determine if the volume being entered is a
physical (non-VTS) volume, a logical volume, or a logical volume being imported.
If the shelf location field for a logical volume being imported indicates
STACKED=volser at the beginning of the field, this information is passed to the
entry exit and is cleared upon successful entry of the volume. This should be the
exported stacked volume that was recorded in the volume record in the TCDB
when the logical volume was exported.
If the cartridge entry processing in the manual tape library, was initiated with the
manual cartridge entry programming interface, the 16-byte pass through value
specified with the EXITINFO keyword on the CBRXLCS FUNC(MCE) macro
invocation in passed to the installation exit as an input-only value. Otherwise,
UXEEXITI contains binary zeros.
Since cartridge entry processing in a manual tape library can be initiated by the
MCE programming interface, or the LIBRARY ENTER command, the tape device
Chapter 7. Installation Exits
223
selection field UXEMEDIA may be modified by the installation exit. If a media
type is not provided before the invocation of the exit, and the exit makes no
changes, entry processing for this volume fails, but processing for other volumes
continues. However, if the exit explicitly modifies the media type and specifies an
invalid value, entry processing is discontinued for this and all subsequent volumes.
For entry processing in an automated tape library dataserver, UXEMEDIA is an
input only field (the media type returned by the vision system is used).
The following values are validity checked upon return from the exit:
v Volume use attribute
S(SCRATCH) or P(PRIVATE) can be specified.
v Storage group name
For a volume use attribute of SCRATCH, the storage group name that is
supplied by the exit is ignored. OAM sets the storage group name to
*SCRTCH*. If the library supports outboard policy management, the default
policy (blanks) is set at the library.
For a volume use attribute of PRIVATE, the storage group name may be set to
blanks. A nonblank storage group name is always validity checked, even if the
installation exit has not changed the value. The storage group name must be
defined in the active SMS configuration as a tape storage group, and the library
into which the volume is entered must be one of those in which the storage
group resides. If the storage group name does not pass validation, and it is not
provided by the installation exit, the cartridge is ejected, but cartridge entry
processing continues.
v Storage class name
For a volume use attribute of SCRATCH, the storage class name that is supplied
by the exit is ignored. If the library supports outboard policy management, the
default policy (blanks) is set at the library.
For a volume use attribute of PRIVATE, the storage class name that is supplied
may be blank. If a nonblank volume is supplied, the name must only conform to
SMS naming convention standards. See “Syntax Rules” on page 225 for the
syntax checking that is performed.
v Management class name
For a volume use attribute of SCRATCH, the management class name that is
supplied by the exit is ignored. If the library supports outboard policy
management, the default policy (blanks) is set at the library.
For a volume use attribute of PRIVATE, the management class name that is
supplied may be blank. If a nonblank volume is supplied, the name must only
conform to SMS naming convention standards. See “Syntax Rules” on page 225
for the syntax checking that is performed.
v Data class name
For a volume use attribute of SCRATCH, the data class name that is supplied by
the exit is ignored. If the library supports outboard policy management, the
default policy (blanks) is set at the library.
For a volume use attribute of PRIVATE, the data class name that is supplied
may be blank. If a nonblank volume is supplied, the name must only conform to
SMS naming convention standards. See “Syntax Rules” on page 225 for the
syntax checking that is performed.
v Write protection status
Y, N, or blank can be specified.
v Checkpoint volume indicator
224
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Y, N, or blank can be specified.
v Last mounted date
The date specified must be in ISO format (YYYY-MM-DD) or blanks.
v Last written date
The date specified must be in ISO format (YYYY-MM-DD) or blanks.
v Volume expiration date
The date specified must be in ISO format (YYYY-MM-DD) or blanks.
v Tape device selection information:
– Tape recording technology may be specified as unknown, 18-track, 36-track,
128-track, 256-track, 384-track, EFMT1, EFMT2, EEFMT2, EFMT3, or EEFMT3.
The recording technology must be applicable for the media type. If it is
returned as unknown and there is only one applicable recording technology
for the media type, the applicable recording technology is set by default. If
the volume is PRIVATE and the media type has more than one applicable
recording technology, it is invalid for the installation exit to return unknown
for the recording technology. The following are valid recording technology
and media type combinations:
- MEDIA1 and 18-track or 36-track (or unknown if volume is SCRATCH)
- MEDIA2 and 36-track or unknown
- MEDIA3, MEDIA4 and 128-track, 256-track, or 384-track (or unknown if
volume is SCRATCH)
- MEDIA5, MEDIA6, MEDIA7, MEDIA8 and EFMT1, EFMT2, EEFMT2,
EFMT3, or EEFMT3 (or unknown if volume is SCRATCH)
- MEDIA9, MEDIA10 and EFMT2, EEFMT2, EFMT3, or EEFMT3 (or
unknown if volume is SCRATCH)
– For automated cartridge entry, the media type returned by the hardware is
always used.
– Compaction may be specified as unknown, none, or compacted.
– Special attribute may be specified as none or read-compatible.
Syntax Rules: The values that you specify for the storage group, storage class, data
class, and management class construct (policy) names must meet the following
SMS naming convention standards:
v
v
v
v
Alphanumeric and national characters only
Name must begin with an alphabetic or national character ($*@#%)
No leading or embedded blanks
Eight characters or less
Shelf location and owner information are not validity checked.
If the installation exit returns with an invalid value in a parameter field, returns
with an invalid return code, or abnormally terminates, cartridge entry processing is
discontinued until OAM has been stopped and restarted, or the LIBRARY
RESET,CBRUXENT command has been issued to reenable the cartridge entry
installation exit. This is intended to prevent the inadvertent assignment of a private
volume to scratch status. For an automated tape library dataserver, the volume
remains in the insert category.
Note: During cartridge entry processing in an ATLDS, it is not possible to
determine which system in an SMS complex will perform cartridge entry
processing for any particular occurrence unless the LIBRARY
DISABLE,CBRUXENT command has been issued to disable cartridge entry
installation exit processing on a system. However, to prevent unpredictable
Chapter 7. Installation Exits
225
results, the installation should provide the same cartridge entry installation
exit for each system in the SMS complex. If the library is being partitioned,
each system in the TCDBplex must also run with the same cartridge entry
installation exit. The LIBRARY DISABLE,CBRUXENT command can be used
to test a new version of the exit by forcing cartridge entry processing to
occur on a particular system.
Outboard Policy Management Processing When Calling the
Entry Exit
If the library has outboard policy management support enabled, the UXELOPM
indicator is set on in the CBRUXEPL parameter list to indicate that the library is
enabled for outboard policy management support.
If a volume has nondefault policy names assigned to it, as may be the case with an
imported logical volume, the library policy names are passed to the entry exit in
the UXELMOPM fields. The UXEVOPM indicator is set on to indicate that at least
one of these fields has a nondefault policy name. Otherwise, by default, blanks are
passed in these fields. See “Cartridge Entry Installation Exit Parameter List
(CBRUXEPL)” on page 228 for more information on these new fields in the
parameter list.
The following indicators are set if the import list explicitly sets a policy name:
UXEVSGSP
The storage group name is explicitly set by the import list.
UXEVMCSP
The management class name is explicitly set by the import list.
UXEVSCSP
The storage class name is explicitly set by the import list.
UXEVDCSP
The data class name is explicitly set by the import list.
If a volume being entered has a TCDB record, the UXEGROUP field will contain
the TCDB storage group, unless explicitly specified through the import list
(indicated by bit flag UXEVSGSP). If the UXEVSGSP indicator is set, and the use
attribute is PRIVATE, the UXEGROUP field contains the value specified in
UXELMSG. This ensures that any changes through the import list are reflected in
the TCDB record. UXELMSG will contain the storage group policy name that exists
in the library if a nondefault policy name exists or blanks, by default. For a private
volume, if the TCDB storage storage group is blanks and the library has a
nondefault policy name, the UXELMSG value is also assigned to UXEGROUP.
If a volume being entered does not have a TCDB record, and the library has a
nondefault policy name, the UXEGROUP field contains the value specified in
UXELMSG. This ensures if the entry exit makes no changes, or changes the use
attribute to PRIVATE, that the TCDB storage group field and the library manager
policy names are the same.
226
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Outboard Policy Management Processing When Returning
from the Entry Exit
If the use attribute is SCRATCH when returning from the exit and the library
supports outboard policy management, the construct names at the library are set to
the default policy names, which contain blanks.
If the use attribute is PRIVATE when returning from the exit and the library does
not support outboard policy management, the storage group policy name set by
the cartridge entry installation exit (CBRUXENT) is stored in the TCDB, but the
policy names for storage class, management class and data class in the new policy
fields are ignored.
For a private volume, if the library supports outboard policy management, the
cartridge entry installation exit (CBRUXENT) can assign or change policy names in
the new fields. To change the storage group, use UXEGROUP, as UXELMSG is an
input-only field.
To change the policy names or assign new names for storage class, management
class, or data class policies, the exit can update the respective fields: UXELMSC,
UXELMMC, UXELMDC. Upon return, these fields are checked for valid syntax
(starts with an alphabetic or a national character [$*@#%], contains no embedded
blanks, contains alphanumeric and national characters only); otherwise, the fields
must contain all blanks in order to set the default policy names. These constructs
are not validated to ensure that they are valid SMS constructs in the current SCDS
as is done for the storage group. If the construct names are syntactically correct,
the library is updated with these policy names. This approach provides greater
flexibility, especially on import.

Cartridge Entry Installation Exit (CBRUXENT) Return Codes
The following are the return codes that can be passed back from the exit:
Code
Meaning
0
Perform cartridge entry as requested. No changes have been made to the
parameter list (CBRUXEPL). Use what existed at the time the installation
exit was called.
Chapter 7. Installation Exits
231
4
Perform cartridge entry and note that one or more fields in the parameter
list (CBRUXEPL) have changed.
8
Do not allow this cartridge to be entered. For an automated tape library
dataserver, OAM schedules the cartridge to be ejected.
12
Ignore the cartridge entry request. For an automated tape library
dataserver, OAM leaves the cartridge in the library (volume left in the
insert category).
16
Do not call the cartridge entry installation exit again. Perform cartridge
entry as requested using the attributes that existed at the time that the exit
was originally called.
If an invalid return code is passed back, OAM discontinues cartridge entry
processing.
Note: Once OAM is told not to invoke the installation exit again (return code 16)
or cartridge entry processing is discontinued, the only way to reactivate the
exit is to stop and restart OAM, or to issue the LIBRARY RESET,CBRUXENT
command.
Cartridge Entry Installation Exit (CBRUXENT) Usage
Requirements
The cartridge entry installation exit must reside in load module CBRUXENT. It is
invoked by OAM by way of the MVS LINK macro and must reside in a library in
the LNKLST concatenation. The installation exit can be executed above or below
the 16-MB line. If multiple tape libraries are defined to the system, the installation
exit must be coded and link-edited on the system as re-entrant.
The following characteristics describe the execution environment in which the
cartridge entry installation exit is invoked:
v Task mode
v Unlocked
v Noncross memory mode (HASN = PASN = SASN)
v The addressing mode specified when the exit was linkage edited
v Primary ASC mode (not AR mode)
v Key 5, problem state; or a user key, supervisor state
Rule: Mapping macro CBRUXEPL must be included by the installation exit.
Cartridge Eject Installation Exit (CBRUXEJC)
The cartridge eject installation exit (CBRUXEJC) is called to approve or disapprove
a request to eject a volume from a tape library, as a notification call when a logical
volume has been exported, as a notification call when a volume eject has failed,
and to determine the TCDB volume record disposition and contents for each
volume.
The cartridge eject installation exit is supplied by DFSMSrmm. If your installation
is not using DFSMSrmm, the supplied exit returns a return code of 16, indicating
that the installation exit not be invoked again. For more information, see z/OS
DFSMSrmm Managing and Using Removable Media, z/OS DFSMSrmm Implementation
and Customization Guide, and z/OS DFSMSrmm Diagnosis Guide.
If your installation is not using DFSMSrmm and your tape management vendor
has not supplied an exit, OAM provides a sample cartridge eject installation exit
232
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
(CBRSPUXJ) in SAMPLIB that can be customized to fit your needs. The discussion
that follows will assist in determining whether the exit is needed on your system.
For more information on this SAMPLIB member, see “SAMPLIB Member
CBRSPUXJ” on page 286.
The following library-related information is passed to the exit. None of the

The fields that are not marked as input only may be modified by the exit. If it is
described as output, it may be updated by the installation exit. If it is further
described as verified, the contents or format of the field is validity checked before
updating the TCDB volume record with information from the installation exit. Date
fields are in ISO format (YYYY-MM-DD).
Chapter 7. Installation Exits
233
The 16-byte pass-through value specified with the EXITINFO keyword on the
CBRXLCS FUNC(EJECT) macro invocation is passed to the installation exit as an
input-only value. If the eject request has come from any source except CBRXLCS,
the field contains binary zeros.
If a volume record disposition of purge (P) is returned by the installation exit, the
only value retained from the parameter list is the shelf location. This enables the
proper shelf location to be displayed upon eject completion.
If a volume record disposition of keep (K) is returned by the installation exit, the
following values are checked for validity:
v Volume use attribute
S (SCRATCH) or P (PRIVATE) can be specified.
v Storage group name
For a volume use attribute of SCRATCH, OAM sets the storage group name to
*SCRTCH*. Any name supplied by the exit is ignored. For a volume use
attribute of PRIVATE, the storage group name may be set to blanks. If a
nonblank value is provided, the storage group must be part of the active
configuration, and it must be a tape storage group.
v Write protection status
Y, N, or blank can be specified.
v Checkpoint volume indicator
Y, N, or blank can be specified.
v Last mounted date
The date specified must be in ISO format (YYYY-MM-DD) or blanks.
v Last written date
The date specified must be in ISO format (YYYY-MM-DD) or blanks.
v Volume expiration date
The date specified must be in ISO format (YYYY-MM-DD) or blanks.
Shelf location and owner information are not validity checked.
If the installation exit returns with an invalid value in a volume record field,
returns with an invalid return code, or abnormally terminates, cartridge eject
processing is discontinued until OAM has been stopped and restarted, or the
LIBRARY RESET,CBRUXEJC command has been issued to re-enable the cartridge
eject installation exit.
Failed Eject Notification Processing
If an eject request fails after the exit has been invoked, the tape configuration
database, your tape management system database, and the library manager
database might report the library residency of the volume differently. To help avoid
these discrepancies, on the initial call to the exit (UXJNCALL value UXJEJECT), the
UXJCBACK indicator can be set by the exit. If this indicator is set and the eject
request then fails, a failed eject notification call is made to the exit (UXJNCALL
value UXJRFAIL). This call provides an opportunity for the tape management
system to update its database information on the residency of the volume.
Note: Failed eject notification support is not performed for manual tape library
volumes.

z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Export Completion Processing
Unlike a physical volume, to remove a logical volume with data from a VTS, it
cannot be ejected from the library.
To remove a logical volume with data from a library, the volume must be
physically exported from the library. For more information on the export process,
see “Exporting Logical Volumes from a 3494 VTS System” on page 37.
When a logical volume is successfully exported from the library, the cartridge eject
installation exit is notified and a notification call indicator (UXJEXPRT) is set in
field UXJNCALL. The volume serial number of the stacked container volume on
which the logical volume resides can be found in the stacked volume container
field, UXJSTKVS. The installation or its tape management system then stores the
container information for later use when the logical volume is imported back into
a library. If the TCDB is shared across multiple systems but each system has its
own tape management system database, the exit can return with RC=12 (IGNORE)
if the exported volume is not known to this tape management system. This leaves
the volume in the exported category to be processed by a system that “owns” that
volume. If appropriate for the installation, the 32-character free form shelf location
field in the TCDB volume record (located in the UXJSHLOC field of the cartridge
eject installation exit parameter list) can also be used to store the container volume
serial number. This would require that the volume record be kept after a logical
volume is exported from the library.
If the volume record disposition returned from the exit indicates that the volume
record should be kept and the shelf location returned from the exit is blank, LCS
automatically stores the container volume serial number in the shelf location field
of the volume record as STACKED=volser. This information can later be used in the
volume-not-in-library installation exit (CBRUXVNL) to assist the installation and
operator in importing a logical volume. LCS also stores this information if the exit
is not to be invoked, the volume record disposition is KEEP, and the shelf location
is blank.
This call to the installation exit is a notification call only because the export
operation for the logical volume is near completion. This means that the logical
volume has already been written to a stacked volume, which will soon be ready
for removal. All cartridge eject parameter list fields that can be updated today
when a physical volume is ejected from a library can be updated when a logical
volume is exported from a library and are subject to the same validity checks. If
the export then fails during completion processing, the library recovers by putting
the exported volume back into the insert category. There is no failed eject
notification call.

OAM obtains storage below the line, from subpool 0, key 5, for the installation exit
parameter list.
Cartridge Eject Installation Exit (CBRUXEJC) Return Codes
The following are the return codes that can be passed back to OAM:
Code
Meaning
0
Perform cartridge ejection as requested. No changes have been made to the
parameter list (CBRUXJPL). Use the attributes that existed at the time the
installation exit was originally called.
4
Perform cartridge ejection and note that one or more fields in the
parameter list (CBRUXJPL) have changed.
8
Do not allow this cartridge to be ejected.
12
Ignore export completion processing for this logical volume. OAM leaves
the volume in the library in the exported category.
16
Do not call the cartridge eject installation exit again and perform cartridge
ejection as requested using the attributes that existed at the time the
installation exit was originally called.
Note: If an invalid return code is passed back, OAM discontinues cartridge eject
processing.
Cartridge Eject Installation Exit (CBRUXEJC) Usage
Requirements
The cartridge eject installation exit must reside in load module CBRUXEJC. It is
invoked by OAM through the MVS LINK macro and must reside in a library in
the LNKLST concatenation. The installation exit can be executed above or below
the 16-megabyte line. If multiple tape libraries are defined to the system, the
installation exit must be coded and linkedited on the system as reentrant.
Note: Once OAM is told not to invoke the installation exit again (return code 16)
or cartridge ejection processing is discontinued, the only way to reactivate
the exit is to stop and restart OAM, or issue the LIBRARY
RESET,CBRUXEJC command.
The following characteristics describe the execution environment in which the
cartridge eject installation exit is invoked:
v Task mode
v Unlocked
v Noncross memory mode (HASN = PASN = SASN)
v The addressing mode specified when the exit was linkage edited
v Primary ASC mode (not AR mode)
v Key 5, problem state
Mapping macro CBRUXJPL must be included by the installation exit.
Volume Not in Library Installation Exit (CBRUXVNL)
The volume not in library installation exit (CBRUXVNL) receives control under a
variety of circumstances and error conditions. The primary purpose of the exit is to
give the installation the opportunity to enter a volume into a tape library during
job step setup, device allocation, and library mount processing.
240
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
The volume not in library installation exit is supplied by DFSMSrmm. If your
installation is not using DFSMSrmm, the supplied exit returns a return code of 16,
indicating that the installation exit not be invoked again. For more information, see
z/OS DFSMSrmm Managing and Using Removable Media, z/OS DFSMSrmm
Implementation and Customization Guide, and z/OS DFSMSrmm Diagnosis Guide.
If your installation is not using DFSMSrmm and your tape management vendor
has not supplied an exit, OAM provides a sample volume not in library
installation exit (CBRSPUXV) in SAMPLIB that can be customized to fit your
needs. The discussion that follows will assist in determining whether the exit is
needed on your system. For more information on this SAMPLIB member, see
“SAMPLIB Member CBRSPUXV” on page 293.
Note: For an MTL, the LIBRARY ENTER command can be used to allow an
operator to enter the desired volume into the MTL.
Invoking the Installation Exit
This installation exit can be invoked during the following processing steps:
v Job step setup
v Device allocation
v Library mount
The following conditions can cause invocation of the exit:
v If some of the tape volumes in a multivolume tape data set are not resident in a
tape library, the request would fail, because all the tape volumes belonging to
the same multivolume data set must reside in the same tape library. The exit can
be used to direct the missing tape volumes back into the library.
Note: In a multivolume data set request, during job step setup and device
allocation processing, the exit is only invoked when the first volume of
the data set does not reside in a tape library. However, later during
library mount processing, the exit is invoked each time a multivolume
data set volume is needed but does not reside in the tape library. The exit
can wait until library mount processing to get the additional volumes
entered on an “as needed” basis, or if it is known that specific
applications always use the entire multivolume data set, the exit, during
job step setup, can instruct the operator to enter all volumes of the
multivolume data set. The choice is determined by the exit. However,
keep in mind that the exit is only passed one volume serial number at a
time, and is not passed all the volumes in the multivolume data set, nor is
it passed any data set information.
v If none of the tape volumes reside in a tape library, or the tape volumes were
previously resident in a tape library but are currently shelf-resident, they are
considered non-SMS managed tape volumes and are allocated to a tape drive of
the appropriate device type outside a tape library. The exit can be used to enter
the tape volumes into a tape library.
For example, if the only 3490E tape drives that an installation has are inside a
tape library, then whenever a shelf-resident enhanced capacity cartridge system
tape is requested, it must be entered into a tape library containing a 3490E tape
drive. The exit can be used to direct the enhanced capacity cartridge system tape
into a library that is capable of handling the request.
Note: Before invoking the exit during job step setup, OAM does not know if
there are any stand-alone drives capable of handling the volume. The exit
is invoked to report that the tape volume is not in a tape library, and it
Chapter 7. Installation Exits
241
allows the exit to decide whether the volume should reside in a tape
library, and if so, which tape library should be used.
v If a tape volume is ejected from a tape library between job step setup and
library mount processing, the request requiring the tape volume would fail. The
exit can reenter the required tape volume into the specified tape library to
prevent the job from failing.
However, if a logical volume is being exported from a tape library dataserver
between job setup and library mount processing, the mount request immediately
fails, since an export operation is not immediate.
Note: The input to the exit at device allocation does not identify the library to
which the tape volume must return, because the information was erased
when the volume was ejected from the library. Therefore, the exit must
rely upon other sources to determine which library should receive the
missing volume.
v If tape volumes are not library-resident in a tape library and are physically
located in a remote area, requests for these volumes are allocated to stand-alone
tape drives and are delayed until the volumes are retrieved and mounted on the
stand-alone tape drives. While jobs are waiting for these tape volumes to be
mounted, the system resources allocated to these tape volumes are unavailable
for use by other jobs. CBRUXVNL can identify this condition and interact with
the installation’s tape management system to determine the best course of action
to alleviate this waste of time and resource.
v Since the ATLDS has a finite tape cartridge capacity, infrequently used tape
volumes may be ejected until their next scheduled use. These tape cartridges
should be reentered in advance of reuse to avoid job processing delays, but since
this is not always possible, this exit can be used to identify and correct this
condition, preventing job failures.
Note: With JES3, the job step notification occurs before the job being scheduled
for execution. Therefore, missing tapes can be located and entered into the
tape library well in advance of usage.
Processing Options for the Installation Exit
The following options are available to the exit:
v Continue without entering the cartridge into a library.
v Locate the requested volume and enter it into a tape library.
v Cancel the request immediately.
v Indicate that the exit not be invoked again.
Logical Volume Considerations
If a logical volume is requested to be mounted, it is important that the installation
exit also display the exported stacked volume that contains the logical volume. If
the OAM supplied default is being used, this information is automatically
displayed if the shelf location in the TCDB volume record is STACKED=volser.
Entering Tape Volumes in the Library Using the Installation
Exit
To enter tape volumes into the library under the direction of the exit, the following
conditions must both be met:
v OAM must be up and running on at least one of the systems sharing the tape
library dataserver in the SMS complex or TCDBplex.
242
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
v OAM must have been started since the most recent IPL on the system running
the requested job.
When entering a volume into a tape library under the direction of CBRUXVNL,
you must set the volume use attribute to PRIVATE; otherwise, the request fails.
This is because only specific volume requests are handled by the exit and a specific
volume request for a scratch tape is not permitted. Volume use attributes are set by
default from the ISMF Library Definition or by the cartridge entry installation exit.
Perform the following steps when you enter a volume into a tape library:
v Locate the requested volume using the tape management system inventory.
v Enter the volume into a tape library (or if indicated, the specific tape library).
For a logical volume, enter the required exported stacked volume and initiate a
single volume import at the library manager console.
v Reply to the outstanding WTOR at the MVS console.
Note: If the exit is waiting for an extended period for human intervention to finish
processing, this causes delays for other jobs that may be processing at the
same time or that may need the same resources as the job for which the exit
is active. If the volume is not entered into the library within 15 minutes,
CBR3646D is issued indicating that the operator should retry or cancel the
job request.
Possible Error Conditions
The installation may introduce a number of error conditions in the process of
re-entering a cartridge into a library under the control of the volume not in library
installation exit. The following errors may cause immediate or eventual job
failures:
v Entering a volume into the wrong library (prompts the issuance of message
CBR3646D)
v Setting the wrong storage group name in the cartridge entry installation exit
v Setting incorrect tape device selection information in the cartridge entry
installation exit
v Setting the scratch volume use attribute in the cartridge entry installation exit
incorrectly
v Inadvertently requesting a volume with a level of TDSI information not
recognized by the system
Note: If the operator enters the volume into the wrong library, or OAM is not
aware of the entry of the volume within 15 minutes, OAM issues the
CBR3646D message. This allows the operator the opportunity to correct the
situation and retry or cancel the operation.
The best way to avoid these errors is to not eject the volumes in the first place. If
this is not practical, then the tape volume record should be kept by using the
KEEP option of the LIBRARY EJECT operator command or through the ISMF
Mountable Tape Volume line operator when the volume is ejected. This preserves
the information about the tape volume so that the Cartridge Entry Installation Exit
does not have to rebuild the tape volume record.
If a job on a lower-level system inadvertently requests a volume whose media type
or recording technology is not understood at this software level, the exit can cancel
the job, returning a return code 8, or it can proceed with entering the volume. If
the exit proceeds and enters the volume, once it is successfully entered on an
up-level system and the exit returns with a return code 4 (indicating retry), the job
Chapter 7. Installation Exits
243
on the down-level system fails during job step setup on subsequent retrieval of the
volume record. If the host detects that it is an up-level volume (if the TCDB
volume record exists), the call to the exit is bypassed and the job is canceled.
Job Step Setup
CBRUXVNL is invoked during job step setup processing to provide an opportunity
to enter the tape volume into any tape library chosen. The call to the exit is made
when the first or only volume serial number specified on the DD statement or
dynamic allocation request is not an online DASD volume and no record exists in
the TCDB for the volume, or a record exists but indicates the volume is
shelf-resident. Shelf-resident means the tape volume was ejected from the tape
library with the KEEP option, which retained the TCDB record. For new data sets,
this occurs just before calling the ACS routines; for old data sets, this occurs when
the TCDB search completes before device allocation.
Note: Refer to APAR OA11079, available at z/OS V1R4 and above, for changes to
the processing related to offline DASD volumes. With this APAR installed,
or starting with z/OS V1R8, during DISP=OLD processing, the CBRUXVNL
exit is no longer called for offline DASD volumes.

Table 24 lists the job information fields and possible content when invoked for job
step setup. Job information is only passed to the exit during the job step setup
CBRUXVNL invocation as this is the critical time for the exit to determine if the
volume should be entered into a library. At device allocation and library mount
processing, it has already been determined that the volume should reside in a tape
library; therefore, job information is not passed to the CBRUXVNL installation exit
for these invocations.

UXNDISP
Disposition fields (UXNDISP1, UXNDISP2,
UXNDISP3) - contain standard JCL disposition
parameters (status, normal, abnormal). May contain
zeros if not available or, in some cases, may contain
default disposition settings
UXNCATLG and UXNDEVTP
If the UXNCATLG is on, UXNDEVTP contains the
4-byte device type from the catalog. For old
allocations, if a volser was not specified and the
dataset is cataloged, then the UXNCATLG indicator is
set on and the UXNDEVTP field contains the 4-byte
device type from the catalog. Otherwise, the
UXNCATLG indicator is off and the UXNDEVTP
field contains zeros. When unit information is
available (UNIT=), the UXNUNIT field contains the
passed value; otherwise, the UXNUNIT field contains
zeros.
Device Allocation
If a tape volume is inadvertently ejected from a tape library between job step setup
processing and device allocation, the exit is invoked during device allocation to let
the installation reenter the volume. This invocation occurs for the first or only
volume of the request when there is no TCDB record or the volume is
Chapter 7. Installation Exits
245
shelf-resident. The requested volume should be entered into the tape library in
which it was resident during job step setup.
Note: Although there are circumstances in which the job may run successfully if
the volume is entered into any tape library, it is recommended that the
volume be entered into the library in which it was resident during job step
setup.

Library Mount Processing
If a tape volume is inadvertently ejected from a tape library between device
allocation and library mount processing, the exit is invoked during library mount
processing to let the installation reenter the volume. This exit is only invoked when
the tape library fails a mount request because the tape volume is being ejected or
cannot be found in the tape library. To prevent the CBR3646D message from being
issued, the requested volume must be reentered into the tape library in which it
was resident when the tape drive was allocated.

Volume Not in Library Installation Exit Return Codes for Job
Step Processing
The following return codes can be passed back to OAM from CBRUXVNL for job
step setup processing:
Code
Meaning
0
Perform normal processing.
The system allocates a stand-alone tape drive capable of handling the
requested volume. If the required device type is not installed, the job or
dynamic allocation fails.
4
Retry the failing operation.
Locate the requested tape volume, using the tape management system
inventory or other sources, and enter it into any tape library connected to
the system on which the requesting job is running.
The system rereads the tape volume record for the specified tape volume.
If the tape volume record exists in the TCDB and the record indicates that
the volume is library-resident, the system proceeds with normal
library-resident tape volume processing. If the tape volume record exists
but indicates that the tape volume is still shelf-resident, the CBR3646D
message is issued to allow the operator to retry or cancel the job request.
Note: CBRUXVNL is mostly used for old data sets, but new data sets can
specify a specific volume serial number. When this occurs and the
volume is entered into a tape library at the direction of CBRUXVNL,
the library name is subsequently made available to the ACS
routines. The ACS routines must assign a storage class and a tape
storage group to the request; otherwise, the request fails.
8
Cancel.
The job step or dynamic allocation is canceled.
16
Do not call the exit again.
CBRUXVNL is not invoked again until reactivated. The system allocates a
stand-alone tape drive. If there is no stand-alone tape drive capable of
handling the tape volume request, the job or dynamic allocation fails.

Volume Not in Library Installation Exit Return Codes for
Device Allocation
The following return codes can be passed back to OAM from CBRUXVNL for
device allocation processing:
Code
Meaning
0
Perform normal processing.
The job step or dynamic allocation fails.
4
Retry the failing operation.
Locate the requested tape volume, using the tape management system
inventory or other sources, and enter it into the specific tape library in
which it was previously resident when the job step was set up.
The system rereads the tape volume record for the specified tape volume.
If the tape volume record exists in the TCDB and the record indicates that
the volume is library-resident, the system proceeds with normal
library-resident tape volume processing. If the tape volume record does not
exist or the tape volume record exists but indicates that the tape volume is
still shelf-resident, the CBR3646D message is issued allowing the operator
to retry or cancel the job request.
8
Cancel.
The system cancels the job step or dynamic allocation.
16
Do not call the exit again.
The job step or dynamic allocation fails. The installation exit is not called
again until it is reactivated.
Volume Not in Library Installation Exit Return Codes for
Library Mount Processing
The following return codes can be passed back to OAM from CBRUXVNL for
library mount processing:
Code
Meaning
0
Perform normal processing.
The job step or dynamic allocation is failed.
4
Retry the failing operation.
Locate the requested volume, using the tape management system inventory
or other sources, and reenter the volume into the tape library identified by
the UXNLIB field of the installation exit parameter list.
If the tape volume record still indicates that the tape volume is
shelf-resident or the volume was entered into the wrong library, the
CBR3646D message is issued. This message indicates which library the
CBRUXVNL volume should be entered into and prompts the operator to
retry or cancel the job request.
8
Cancel the job step.
The job step or dynamic allocation fails.
16
Do not call the exit again.
The job step or dynamic allocation fails. The exit is not called again.
Chapter 7. Installation Exits
253
If the installation returns a return code 16, indicating that the exit not be invoked
again, or the installation exit is deactivated as the result of an abnormal
termination or an invalid return code, the exit can be reactivated by stopping and
restarting the OAM address space, or by issuing the LIBRARY RESET,CBRUXVNL
command.
Volume Not in Library Installation Exit (CBRUXVNL) Usage
Requirements
The volume not in library installation exit must reside in load module
CBRUXVNL. It is invoked by way of the MVS LINK macro and must reside in a
library in the LNKLST concatenation.
Since the volume not in library installation exit (CBRUXVNL) receives control
through an MVS LINK macro, the addressing mode on entry to the exit may be
either 24-bit or 31-bit addressing mode. Also, the installation exit can be executed
above or below the 16-megabyte line. The addressing mode and the residency
mode are determined by whatever AMODE (for addressing mode) or RMODE (for
residency mode) characteristics are assigned to the load module when it is created
by the MVS Linkage Editor and Loader or the MVS Program Binder.
Because the exit may be invoked in a key other than the job key:
v All storage dynamically acquired by the exit must be obtained from subpool 227,
228, 229, 230, 231, or 241.
v The exit must be written as a reentrant program and the resulting load module
must be link-edited on the system as REENTRANT.
The following characteristics describe the execution environment in which the
volume not in library installation exit is invoked:
v Task mode (not SRB mode)
v Unlocked
v Noncross memory mode (HASN = PASN = SASN)
v The 24-bit or 31-bit addressing mode depending on AMODE characteristics
assigned when load module was created
v APF-authorized load module or in an APF-authorized library
v Primary ASC mode (not AR mode)
v Enabled for I/O external interrupts
v PSW key of the caller might not match the job key
v State of the caller
Note: Because of the environment in which this exit can be given control, invoking
dynamic allocation from within this exit is not supported and can lead to an
abend.
Mapping macro CBRUXNPL must be included by the installation exit.

z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Appendix A. SAMPLIB Members
This appendix contains sample library members that you can modify to suit your
own business requirements.
Sample Library Members
This appendix contains information on sample library members for the following:
v CBRSPLCS, which is an example program that invokes the CBRXLCS
programming interface.
v CBRUXCUA, CBRUXENT, CBRUXEJC, and CBRUXVNL installation exits. For
more information on the specific installation exit that is illustrated in each of
these SAMPLIB members, see Chapter 7, “Installation Exits,” on page 211.
v CBRAPROC that is used to create member OAM in SYS1.PROCLIB.
v CBRSPSIM, CBRSPPIM, CBRSPPIP, CBRSPSXP, and CBRSPPXP, which are JCL
samples that can be used for creating import or export list volumes.
The installation exits, as supplied by DFSMSrmm, are linked in SMP/E as
reentrant. Installation exits CBRUXCUA and CBRUXVNL must be coded and
link-edited on the system as reentrant. If multiple tape libraries are defined to the
system, CBRUXENT and CBRUXEJC must also be coded and link-edited on the
system as reentrant. To demonstrate this, and to provide multiple library support,
the sample jobs for CBRUXCUA, CBRUXVNL, CBRUXENT, and CBRUXEJC are all
coded as reentrant. The linkage editor parameters found in the prolog are used for
each sample job. If you choose to code the installation exits as nonreentrant, you
need to create the JCL to link-edit the exits as nonreentrant.
Note: These SAMPLIB members are available to you as part of z/OS. Refer to
them as examples for exits you may write to suit your own storage
administration plan objectives.
Additionally, there are five sample JCL examples that are provided to illustrate the
format and required files for both the import and export list volume. The JCL is
commented with the expected format of each of the required files followed by
some sample data, if applicable. The following JCL samples are shipped in
SYS1.SAMPLIB:
v CBRSPSIM for import list volume (scratch request). See “SAMPLIB Member
CBRSPSIM” on page 307
v CBRSPPIM for import list volume (private request). See “SAMPLIB Member
CBRSPPIM” on page 310
v CBRSPPIP for import list volume (private request). Illustrates IMPORT LIST 02
format for outboard policy management specifications. See “SAMPLIB Member
CBRSPPIP” on page 313.

v CBRSPPXP for export list volume (private request). See “SAMPLIB Member
CBRSPPXP” on page 320
Both scratch and private examples are provided; however, in order to allocate a
scratch volume in a target library in an installation with multiple libraries, the ACS

255
routines need to direct the device allocation for the scratch mount to a specific
library. To accomplish this, use an exclusive storage group for each library. This
ensures that based on the storage group selected by the ACS routines, the target
library for the export or import operation will be the library selected for the
scratch mount request. This is necessary since the import or export list volume
must reside in the same library as the logical volumes intended for import or
export processing.
To initiate the import or export operation from within the JCL, the specific volser
examples invoke the CBRXLCS FUNC=EXPORT or FUNC=IMPORT functions
using the CBRSPLCS sample program.

MODULE NAME:
CBRSPLCS
*
*
*
*
DESCRIPTIVE NAME: SAMPLE INSTALLATION MANAGEMENT PACKAGE FOR
*
*
AUTOMATED TAPE LIBRARIES
*
*
*
*
FUNCTION:
*
*
MODULE CBRSPLCS IS PART OF THE SAMPLE INSTALLATION
*
*
MANAGEMENT PACKAGE FOR AUTOMATED TAPE LIBRARIES. IT HANDLES
*
*
REQUESTS ENTERED VIA AN INPUT TRANSACTION DATASET:
*
*
1. EJECT A VOLUME FROM A LIBRARY
*
*
2. CHANGE A VOLUME USE ATTRIBUTE TO SCRATCH
*
*
3. CHANGE A VOLUME USE ATTRIBUTE TO PRIVATE
*
*
4. INITIATE AN IMPORT OPERATION
*
*
5. INITIATE AN EXPORT OPERATION
*
*
6. PERFORM CARTRIDGE ENTRY INTO AN MTL (MCE)
*
*
*
*
CBRSPLCS DEMONSTRATES THE USE OF THE FOLLOWING FUNCTIONS:
*
*
1. THE "QUERY VOLUME RESIDENCE" FUNCTION OF CBRXLCS, USED
*
*
TO DETERMINE WHETHER A VOLUME RESIDES IN A LIBRARY.
*
*
2. THE "CHANGE USE ATTRIBUTE" FUNCTION OF CBRXLCS, USED
*
*
TO CHANGE THE USE ATTRIBUTE OF A VOLUME TO SCRATCH OR
*
*
TO PRIVATE.
*
*
3. THE "EJECT" FUNCTION OF CBRXLCS, USED TO EJECT A VOLUME
*
*
FROM A LIBRARY, USING EITHER THE CONVENIENCE OUTPUT
*
*
STATION OR THE HIGH CAPACITY OUTPUT STATION.
*
*
4. THE ABILITY TO PASS 16 CHARACTERS OF INFORMATION TO
*
*
THE CHANGE USE ATTRIBUTE INSTALLATION EXIT AND TO THE
*
*
CARTRIDGE EJECT INSTALLATION EXIT. THE CHARACTER STRING *
*
PASSED HERE CONTAINS AN AUTHORIZATION CODE, SO THAT THE
*
*
EXIT CAN DETERMINE THE SOURCE OF THE REQUEST.
*
*
5. THE "IMPORT" FUNCTION OF CBRXLCS INITIATES AN IMPORT
*
*
OPERATION FOR A VOLUME OR VOLUMES INTO A LIBRARY OR
*
*
TO CANCEL AN IMPORT OPERATION THAT'S ALREADY IN
*
*
PROCESS.
*
*
6. THE "EXPORT" FUNCTION OF CBRXLCS INITIATES AN EXPORT
*
*
OPERATION FOR A VOLUME OR VOLUMES FROM A LIBRARY OR
*
*
TO CANCEL AN EXPORT OPERATION THAT'S ALREADY IN
*
*
PROCESS.
*
*
7. THE "MCE" FUNCTION ILLUSTRATES ENTERING A VOLUME
*
*
INTO AN MTL (MANUAL TAPE LIBRARY).

TRANSACTION CONTAINS THE FOLLOWING INFORMATION:
1. A TRANSACTION CODE, WHICH INDICATES THE REQUESTED
FUNCTION: EJECT, CHANGE THE USE ATTRIBUTE TO SCRATCH,
CHANGE THE USE ATTRIBUTE TO PRIVATE, IMPORT,
EXPORT, OR MCE
2. A TRANSACTION MODIFIER, WHICH INDICATES WHETHER TO
VERIFY THAT THE VOLUME RESIDES IN A LIBRARY BEFORE
ATTEMPTING THE FUNCTION IN THE TRANSACTION CODE. NOTE
THAT CUA MAY BE PERFORMED ON A SHELF-RESIDENT VOLUME,
PROVIDED THAT THERE IS A TAPE VOLUME RECORD IN THE
TAPE CONFIGURATION DATA BASE, AND THEREFORE THAT THE
MODIFIER MAY BE USED TO PREVENT THIS. THE TRANSACTION
MODIFIER IS IGNORED FOR MCE PROCESSING.
3. THE VOLUME SERIAL NUMBER.
4. FOR A REQUEST TO CHANGE THE USE ATTRIBUTE TO PRIVATE,
THE STORAGE GROUP NAME. THIS MAY BE SUPPLIED AS
BLANKS. THE CUA INSTALLATION EXIT MAY THEN SUPPLY A

*
FUNCTION:
*
*
MODULE CBRUXVNL IS INVOKED TO ALLOW THE INSTALLATION TO
*
*
ENTER A TAPE VOLUME INTO A LIBRARY DURING PROCESSING FOR
*
*
THE JOB STEP WHICH REQUIRES THE VOLUME.
*
*
*
*
THE EXIT IS ENTERED AT THE FOLLOWING TIMES:
*
*
*
*
1. JOB STEP SETUP PROCESSING
*
*
*
*
THE DEVICE AND VOLUME REQUIREMENTS FOR THE JOB STEP ARE
*
*
BEING DETERMINED.
*
*
*
*
THE VOLUME MAY HAVE ONE OF THREE STATES:
*
*
A. THE VOLUME IS KNOWN TO BE SHELF-RESIDENT. THERE IS *
*
A TAPE VOLUME RECORD FOR THE VOLUME IN THE TAPE
*
*
CONFIGURATION DATA BASE.
*
*
B. THE VOLUME IS KNOWN TO BE AN EXPORTED LOGICAL
*
*
VOLUME. THERE IS A TAPE VOLUME RECORD IN THE
*
*
TAPE CONFIGURATION DATABASE WITH STACKED=VOLSER
*
*
IN THE SHELF LOCATION FIELD.
*
*
C. THE VOLUME IS UNKNOWN TO THE SYSTEM. THERE IS NO
*
*
TAPE VOLUME RECORD FOR THE VOLUME IN THE TCDB, THE
*
*
VOLUME IS NOT A CURRENTLY MOUNTED DASD VOLUME, AND
*
*
THE VOLUME IS NOT AN SMS-MANAGED DASD VOLUME.
*

*
*
*
*
*
*
*
*
*
*
*
*
*
*
*
*
*
*
*
*
IF THE EXIT CAUSES THE VOLUME TO BE ENTERED INTO A TAPE
LIBRARY:
A. FOR AN EXISTING DATASET, THE REQUEST WILL BE
SMS-MANAGED MOUNTABLE, AND A LIBRARY-RESIDENT TAPE
DRIVE WILL BE ALLOCATED.
B. FOR A NEW DATASET, THE LIBRARY NAME IS PASSED TO
THE ACS FILTER ROUTINES:
1. IF THE FILTER ROUTINES DO NOT MAKE THE REQUEST
SMS-MANAGED MOUNTABLE, A NON-LIBRARY-RESIDENT
TAPE DRIVE IS ALLOCATED. WHEN A MOUNT REQUEST
IS LATER ISSUED, THE VOLUME WILL HAVE TO BE
EJECTED FROM THE LIBRARY BEFORE IT CAN BE
MOUNTED ON THE DRIVE.
2. IF THE FILTER ROUTINES MAKE THE REQUEST
SMS-MANAGED MOUNTABLE, AND THE LIBRARY INTO
WHICH THE VOLUME WAS ENTERED IS NOT INCLUDED IN
ANY OF THE SELECTED TAPE STORAGE GROUPS, SMS
FAILS THE JOB.
3. IF THE FILTER ROUTINES MAKE THE REQUEST
SMS-MANAGED MOUNTABLE, AND THE LIBRARY INTO
WHICH THE VOLUME WAS ENTERED IS INCLUDED IN ONE
OF THE SELECTED TAPE STORAGE GROUPS, A LIBRARYRESIDENT TAPE DRIVE WILL BE ALLOCATED.

*
*

*
*
*
*

*
*
*
*
IF THE EXIT TAKES NO ACTION:
*
A. FOR AN EXISTING DATASET, THE REQUEST WILL BE
*
NON-SMS-MANAGED, AND A NON-LIBRARY-RESIDENT TAPE
*
DRIVE WILL ULTIMATELY BE ALLOCATED.
*
B. FOR A NEW DATASET, A NULL LIBRARY NAME IS PASSED TO *
THE ACS FILTER ROUTINES:
*
1. IF THE FILTER ROUTINES MAKE THE REQUEST SMS*
MANAGED MOUNTABLE, SMS FAILS THE JOB.
*
2. IF THE FILTER ROUTINES DO NOT MAKE THE REQUEST
*
SMS-MANAGED MOUNTABLE, A NON-LIBRARY-RESIDENT
*
TAPE DRIVE IS ALLOCATED.
*
*
2. DEVICE ALLOCATION PROCESSING
*
*
JOB STEP SETUP PROCESSING HAS DESIGNATED THE REQUEST AS
*
SMS-MANAGED MOUNTABLE, BUT THE VOLUME HAS BEEN EJECTED
*
FROM ITS LIBRARY.
*
*
THE VOLUME STATES ARE THE SAME AS FOR JOB STEP SETUP
*
PROCESSING.
*
*
IN A JES2 ENVIRONMENT, IF THE EXIT CAUSES THE VOLUME TO
*
BE ENTERED INTO ANY TAPE LIBRARY, THEN A LIBRARY*
RESIDENT TAPE DRIVE WILL BE ALLOCATED.
*
*
IN A JES3 ENVIRONMENT, THE EXIT MUST CAUSE THE VOLUME TO *
BE ENTERED INTO THE SAME LIBRARY IN WHICH IT RESIDED
*
DURING JOB STEP SETUP PROCESSING. IN THIS CASE, A
*
LIBRARY-RESIDENT TAPE DRIVE WILL BE SUCCESSFULLY
*
ALLOCATED. IF THE EXIT CAUSES THE VOLUME TO BE ENTERED
*
INTO A DIFFERENT LIBRARY, THEN THE JOB STEP WILL FAIL.
*
*
IF THE EXIT TAKES NO ACTION, THEN THE JOB STEP WILL
*
FAIL.
*
*
3. LIBRARY MOUNT PROCESSING
*
*
THE SYSTEM IS ATTEMPTING TO MOUNT THE VOLUME ON A
*
LIBRARY-RESIDENT TAPE DRIVE.
*
*
THE VOLUME MAY HAVE ONE OF FIVE STATES:
*
A. THE VOLUME IS KNOWN TO BE SHELF-RESIDENT. THERE IS *
A TAPE VOLUME RECORD FOR THE VOLUME IN THE TCDB.
*
B. THE VOLUME IS KNOWN TO RESIDE IN A DIFFERENT
*
LIBRARY. THERE IS A TAPE VOLUME RECORD FOR THE
*
VOLUME IN THE TCDB.

*
LIBRARY, BUT VOLUME EJECTION IS ALREADY IN PROGRESS *
AND CANNOT BE CANCELED. THERE IS CURRENTLY A TAPE
*
VOLUME RECORD IN THE TCDB, BUT THIS MAY BE PURGED
*
WHEN VOLUME EJECTION COMPLETES.
*
D. THE VOLUME IS UNKNOWN TO THE SYSTEM. THERE IS NO
*
TAPE VOLUME RECORD FOR THE VOLUME IN THE TCDB.
*
E. THE VOLUME IS KNOWN TO BE AN EXPORTED LOGICAL
*
VOLUME. THERE IS A TAPE VOLUME RECORD IN THE
*
TAPE CONFIGURATION DATABASE WITH STACKED=VOLSER
*
IN THE SHELF LOCATION FIELD.
*
*
NOTE: IF A LOGICAL VOLUME IS EXPORT PENDING OR IN
*
PROCESS OF BEING EXPORTED, THE VOLUME NOT IN LIBRARY
*
INSTALLATION EXIT WILL NOT BE INVOKED. FOR THE EXIT
*
TO BE INVOKED FOR A LOGICAL VOLUME, IT MUST HAVE
*
COMPLETED THE EXPORT PROCESS.
*
*
IF THE EXIT CAUSES THE VOLUME TO BE ENTERED INTO THE
*
TAPE LIBRARY WHERE THE DRIVE RESIDES, THE VOLUME MOUNT
*
WILL BE RETRIED.
*
*
IF THE EXIT TAKES NO ACTION, THEN THE JOB STEP WILL

FAIL.

Appendix B. Using ISMF Panels to Define and Monitor Your
Configuration
This chapter discusses typical ISMF functions for defining and monitoring the SMS
configuration and tape volumes associated with your tape library:
v “Defining a Tape Library” on page 327.
v “Displaying Tape Library Attributes” on page 336.
v “Redefining a Tape Library” on page 340.
v “Altering a Tape Library” on page 342.
v “Copying Tape Library Definitions” on page 345.

v “Auditing Volumes in an Automated Tape Library” on page 359.
v “Altering the Volume Record” on page 362.
v “Ejecting a Volume from a Tape Library” on page 367.
ISMF for the Storage Administrator
The Interactive Storage Management Facility (ISMF) supports the system
administrator in managing tape libraries and tape volumes through the use of
panels and line operator commands. These panels and commands are used to list,
define, display, and alter the tape library and tape volume attributes that make up
the installation’s SMS configuration.
The following series of panels illustrate examples of using ISMF to list, define,
display, and alter information concerning the automated and manual tape library
through the use of ISMF panels and line operators.
Defining a Tape Library
ISMF provides a library management function to allow the storage administrator to
use a series of panels to define the tape libraries needed for their installation.
To define a tape library, select option 10, LIBRARY MANAGEMENT, from the
ISMF Primary Option Menu (as shown in Figure 35 on page 328) to start the
library management dialog.
Note: When defining the libraries associated with the Peer-to-Peer VTS Subsystem,
remember to define the composite library along with the associated
distributed libraries. From an ISMF define perspective, each library is
defined as a separate tape library. Their association is established once
communication is made to the library.

begin the library definition process:
Enter a CDS NAME.
Enter a LIBRARY NAME.
Select option 3, DEFINE.
Notes:
1. The letter “V” is reserved exclusively as the first character in a VOLCAT
volume serial number. It readily identifies the volume serial number as
belonging to a VOLCAT. To avoid confusion with the VOLCAT naming
conventions, you may not use the letter “V” as the first character of a tape
library name. Additionally, tape library names may not begin with numeric
characters. You may use alphabetics and the special characters “$”, “@”, and
“#” for the first character of a tape library name. You may use alphabetic,
numeric, and the aforementioned special characters for the remainder of a tape
library name.
2. After the first library definition, ISMF primes CDS NAME and LIBRARY
NAME with the last used reference values on the Tape Library Application
Selection panel. The default CDS NAME is the single-quoted word ‘ACTIVE’,
which represents the currently active configuration.
Choosing option 3, DEFINE, displays the TAPE LIBRARY DEFINE panel with all
the input fields set to blank. You can enter a definition for LIB1, as shown in the
sample Figure 38 on page 330 and Figure 39 on page 330.

Figure 39. Tape Library Define Panel (Page 2 of 4)
SCDS NAME and LIBRARY NAME are output fields that contain the SCDS and
library name you specified in the Tape Library Management Application Selection
panel.
Specify the following information for the tape library definition in the tape
configuration database and in the current source control data set.
DESCRIPTION
A 120-byte field used for entering a description of the library
definition. There are no restrictions on its content.
LIBRARY ID
330
Establishes the connection between the software-assigned library
name and the tape drives that belong to the library. A valid value
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
is entered as five hexadecimal digits. For an ATLDS, it is defined at
the library by the customer engineer and must also match what is
optionally specified in the HCD LIBRARY-ID parameter. This value
is returned by the control unit in response to a read device
characteristics command. For an MTL, it must match what was
specified in the HCD LIBRARY-ID parameter. Valid values are
00001 – FFFFF; a default value of 00000 is not allowed.
CONSOLE NAME
Specifies the name of the MVS console associated with the tape
library being defined. The console name provides precise routing
of console messages pertaining to a specific library. When the
console name is not specified on the Tape Library Define panel,
console name routing support is not provided. The console name is
passed to the installation exits for their use. To use console name
message routing, the console name defined on this panel must also
be defined in the CONSOLxx member of the PARMLIB (see the
discussion on page 76 for more information on this PARMLIB
member). A valid value is entered as two to eight characters. Valid
characters are alphanumeric, #, @, or $; the first character must be
nonnumeric.
ENTRY DEFAULT DATA CLASS
Specifies the data class to be used to determine the interchange
attributes for private volumes entered into the tape library. No
other attributes of the data class are used. You can use the
cartridge entry installation exit (CBRUXENT) to assign appropriate
interchange values that override the default data class
specifications.
Note: The specified data class name is not automatically assigned
or used as the default data class policy name for outboard
policy management.
ENTRY DEFAULT USE ATTRIBUTE
Specifies the default volume use attribute for the cartridges entered
into the library being defined.
P
Indicates PRIVATE for the entry default use attribute.
These tape cartridges can be used to satisfy specific volume
requests.
S
Indicates SCRATCH for the entry default use attribute.
These tape cartridges can be used to satisfy nonspecific
volume requests.
EJECT DEFAULT
Specifies the default action for the TCDB volume record when a
tape cartridge is ejected from the library being defined.
P
Indicates PURGE for the eject default parameter. The
volume record is deleted from the TCDB.
K
Indicates KEEP for the eject default parameter. The volume
record is kept in the TCDB.
Note: No matter which disposition is specified, the volume record
in the ATLDS library manager inventory is deleted upon
cartridge ejection.
Appendix B. Using ISMF Panels to Define and Monitor Your Configuration
331
When the first define panel is complete, use the DOWN command to display the
second part of the Tape Library Define panel (Figure 39 on page 330). Continue
with the definition for library LIB1 by completing part two of the Tape Library
Define panel.
SCRATCH THRESHOLD
Specify the minimum acceptable number of scratch volumes for each media
type in the library being defined. The following are recognized media
types:
MEDIA1
IBM Cartridge System Tape. The number must be in the
range of 0 to 999999. The default value of this parameter is
0.
MEDIA2
IBM Enhanced Capacity Cartridge System Tape. The
number must be in the range of 0 to 999999. The default
value of this parameter is 0.
MEDIA3
IBM High Performance Cartridge Tape. The number must
be in the range of 0 to 999999. The default value of this
parameter is 0.
MEDIA4
IBM Extended High Performance Cartridge Tape. The
number must be in the range of 0 to 999999. The default
value of this parameter is 0.
MEDIA5
IBM TotalStorage Enterprise Tape Cartridge. The number
must be in the range of 0 to 999999. The default value of
this parameter is 0.
MEDIA6
IBM TotalStorage Enterprise WORM Tape Cartridge. The
number must be in the range of 0 to 999999. The default
value of this parameter is 0.
MEDIA7
IBM TotalStorage Enterprise Economy Tape Cartridge. The
number must be in the range of 0 to 999999. The default
value of this parameter is 0.
MEDIA8
IBM TotalStorage Enterprise Economy WORM Tape
Cartridge. The number must be in the range of 0 to 999999.
The default value of this parameter is 0.
MEDIA9
IBM TotalStorage Enterprise Extended Tape Cartridge. The
number must be in the range of 0 to 999999. The default
value of this parameter is 0.
MEDIA10
IBM TotalStorage Enterprise Extended WORM Tape
Cartridge. The number must be in the range of 0 to 999999.
The default value of this parameter is 0.
When the number of scratch volumes in the library falls below the scratch volume
threshold for that media type, operator action message CBR3660A is issued
requesting that scratch volumes of the required media type be entered into the
library. When the number of scratch volumes exceeds twice the scratch volume
threshold for that media type, the message is deleted.
Attention: It is recommended that a scratch threshold be set for all media types
used within a tape library. If a media type is not being used, the default threshold
value of zero (threshold=0) should be used.
332
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries

“Scratch Threshold Setting and Scratch Allocation Implications” on page 56.
When the second define panel is complete, use the DOWN command to display
the third part of the Tape Library Define panel (Figure 40). Continue with the
definition for library LIB1 by completing part three of the Tape Library Define
panel. You may also need to use part four of the Tape Library Define panel
(Figure 41).

Appendix B. Using ISMF Panels to Define and Monitor Your Configuration
333
INITIAL ONLINE STATUS
Specifies how the library being defined will be associated to each system or
system group in the SMS complex each time this SCDS is activated. The
following are valid values:
v Online (YES)
v Offline (NO)
v Not connected (blank)
A tape library can be connected to any combination of one or more of the systems
or system groups defined in the CDS base, but it is strongly recommended that the
tape libraries be connected to systems rather than system groups. When a tape
library is connected to a system group, the user loses the ability to vary the tape
library online or offline to the individual systems in the system group. The ISMF
Tape Library panels support both system names and system group names.
The system administrator defining the libraries does not need to be logged on to
one of the systems in the SMS complex to define the libraries in that
complex—both the TCDB and the SCDS can be moved after being created.
However, both the SCDS and the TCDB for the SMS complex being defined must
be available to the system administrator during the library definition process.
The definition for the tape library does not take affect until the SCDS to which it is
defined is activated. Once the library is defined within the SCDS and the record
for the library is updated in the TCDB, the attributes assigned to the last defined
library for the SCDS are displayed on the Tape Library Application Selection menu
and the Tape Library Define panel as defaults. These values can be modified to
define other libraries as needed.
After you complete the definition of LIB1, the Tape Library Application Selection
menu (Figure 37 on page 329) is displayed again, and you can define your second
tape library as follows:
1. Enter a LIBRARY NAME (LIB2)
2. Press ENTER
Note: Since LIB1 was the last library defined, the SCDS to which it belongs is
primed to display in the SCDS NAME field on this panel (assuming the
SCDS was reactivated since the definition of LIB1). If you wish to change
the SCDS NAME, you may do so here; otherwise, the library (LIB2) that is
currently being defined will reside in the same SCDS as LIB1.
The Tape Library Define panels (Figure 42 on page 335, Figure 43 on page 335,
Figure 44 on page 336, and Figure 45 on page 336) are again displayed, and you
enter the appropriate information for LIB2.

INITIAL ONLINE STATUS
The status of whether this tape library should be:
v Online (YES)
v Offline (NO)
v Not connected (blank)
to each system or system group in the SMS complex when the SCDS is
activated. As the online/offline status is changed with the SMS VARY,
LIBRARY command, the current status is maintained in the ACDS but not
in the base SCDS. Thus, the status values in the base SCDS may not be
current.
Appendix B. Using ISMF Panels to Define and Monitor Your Configuration
339
The system and system group names shown are the actual names taken
from the base configuration record of the CDS. The number of system and
system group names shown can vary between one and thirty-two. The
display shows the difference between system names and system group
names by preceding each system group name by an asterisk.
Redefining a Tape Library
The storage administrator can redefine a tape library by specifying a tape library
that has a record in the TCDB, but no corresponding library definition in this
SCDS. The Tape Library Redefine panels (Figure 48, Figure 49 on page 341,
Figure 50 on page 341, and Figure 51 on page 342) are displayed when the storage
administrator selects option 3, DEFINE, on the Tape Library Application Selection
panel, and there is already a tape library record for this library name in the TCDB.
The library is redefined since most of the information describing the library
already resides in the TCDB and does not have to be re-entered.
When the redefine panel is first shown, message DGTLM020—ATTRIBUTES
PRIMED appears to emphasize that a redefine is taking place. When END is
pressed, a record is added to the new SCDS. The TCDB is updated only if one of
the relevant fields on a redefine panel is changed. The changes are not effective
until the updated SCDS is activated.

Altering a Tape Library
The Tape Library Alter panels are displayed when a storage administrator selects
option 4, ALTER, on the Tape Library Application Selection panel or enters the
alter line operator on the Tape Library List panel (see Figure 65 on page 355
through Figure 69 on page 357).
You can use the Tape Library Alter option to alter the attributes of an existing tape
library. Altering a library results in updating the library definition within the
specified SCDS and the attributes stored in the TCDB.

Copying Tape Library Definitions
You can copy existing tape library definitions and modify them to create new tape
library definitions through the use of two methods.
One method is to use the attributes assigned to the last tape library defined. These
fields are primed by ISMF from the last library definition. You can modify the
attributes to define a new tape library and the new tape library is added to the
SCDS and the tape configuration database.
Another method of copying existing tape library definitions to create new tape
library definitions is to use the COPY line operator from the Tape Library List
panel (see Figure 65 on page 355 through Figure 69 on page 357). You enter the
COPY line operator in the LINE OPERATOR column next to the tape library you
wish to copy. Press ENTER to copy the existing tape library attributes and the
COPY ENTRY panel is displayed (see Figure 56 on page 346).

Figure 56. Copy Entry Panel
Identifying the From and To Sources for Copying
The from DATA SET NAME field identifies the source that you are copying. It is
primed with the value you specified on the Tape Library Application Selection
panel. The from DEFINITION NAME field identifies the name of the tape library
that you are copying. This field is primed with the value from the LIBRARY
NAME field of the Tape Library List panel.
The to DATA SET NAME field identifies the target SCDS of the copy. It must be a
name of an SCDS. It is primed with the value of the from DATA SET NAME if the
from DATA SET NAME contains an SCDS name. It is primed with blanks if the
from DATA SET NAME is ‘ACTIVE’. The to DEFINITION NAME field identifies
the name of the tape library you wish to define. It is primed with blanks.
In the PERFORM ALTER field, you indicate if you want to change some of the
attributes of the copy you are creating. If you specify Y for YES, you go to the
pertinent Alter panel. If you specify N for NO, you remain on the COPY ENTRY
PANEL, where you can perform another copy or return to the original library list
panel.
When copying a tape library definition from one SCDS into another SCDS, you do
not need to select the PERFORM ALTER option. In the case where a tape library
definition is copied within the same SCDS, you must choose the PERFORM ALTER
option because tape libraries in the same SCDS must differ from one definition to
another.
When you have specified the values, press ENTER to perform the copy.
Deleting a Tape Library Definition
Deleting a tape library definition removes the definition for that tape library from
the specified SCDS and, upon activation of that SCDS, the tape library data server
is unavailable to the system. Deleting a tape library dataserver has no effect on the
346
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
TCDB because there may be other SCDSs that still contain the tape library data
server. In order to delete a tape library from the TCDB, IDCAMS with the DELETE
LIBENTRY parameters must be used.
As part of the tape library definition deletion, all storage group constructs in the
SCDS that are defined as including the library undergoing deletion are updated to
remove that library from the storage group definition. When the last library is
deleted from a tape storage group, the invalid tape storage group definition
remains in the SCDS. The SCDS will not validate until all invalid tape storage
group definitions are either deleted or altered so that they contain at least one tape
library.
From the Tape Library List panel (see Figure 65 on page 355 through Figure 69 on
page 357):
1. Enter DELETE in the LINE OPERATOR column next to the tape library you
wish to delete.
2. Press ENTER.
The Confirm Delete Request panel, Figure 57, is displayed.

4. Press ENTER.
The Tape Library List appears with ‘*DELETE’ in the LINE OPERATOR column
next to the deleted library.
Monitoring and Maintaining Tape Volumes
The ISMF Volume function assists in the maintenance and verification of the tape
volumes within the automated and manual tape library through the use of the
Mountable Tape Volume Application available from the Tape Library application
Selection panel.
Appendix B. Using ISMF Panels to Define and Monitor Your Configuration
347
Using the Mountable Tape Volume Application, storage administrators can use line
operators or ISMF commands to perform inventory tasks against tape libraries and
the library-resident volumes residing in them. These functions can be performed
using the Mountable Tape Volume Application:
v AUDIT a volume, a list of volumes, or a tape library.
v ALTER the use attribute, storage group, shelf location, or owner information of
a volume or list of volumes.
v EJECT a single tape volume (for information on using the EJECT line operator,
see “Ejecting a Volume from a Tape Library” on page 367).
Note: If the library in which the volume resides supports outboard policy
management, the assigned storage class name, management class name, and
data class name are not maintained in the tape configuration database, nor
are they displayed through the mountable tape volume application. Use the
DISPLAY SMS, VOLUME command or the LCS external services QVR
function to obtain this information.
ISMF Mountable Tape Volume Application
The ISMF Mountable Tape Volume Application allows you to create, save, and
restore lists of tape cartridge volumes. A selection panel allows you to generate a
list based on any combination of the following criteria (wildcards are supported):
v A fully or partially specified volume serial number
v A fully or partially specified storage group name
v A fully or partially specified tape library name
You can use the View, Sort, and Hide functions to further customize your volume
lists.
Note: If the TCDB is being shared across multiple z/OS system levels, volume
levels containing TDSI information that is not understood by the level of the
software on the system will not be displayed when a volume list is
requested from ISMF. This prevents the z/OS system from processing
volume records containing TDSI information that is not understood by the
system.
Generating a Mountable Tape Volume List
There are actually two options available from the ISMF Primary Option menu that
can be used to assist you in generating a Mountable Tape Volume List. Both
approaches are discussed in the following information.
Follow these steps to display the Mountable Tape Volume Selection Entry panel
using the Library Management option of the ISMF Primary Option Menu.
1. Select option 10, Library Management, from the ISMF Primary Option Menu
(see Figure 35 on page 328). ISMF displays the Library Management Selection
menu (see Figure 36 on page 328).
2. Select option 3, TAPE LIBRARY. This in turn, displays the Tape Library
Application Selection panel (Figure 37 on page 329).
Note: Depending on the information provided on this screen, selecting option
1, LIST, and pressing ENTER can either display a list that includes a
single library, a fully or partially specified library, or a list of all the
libraries associated with the SCDS primed on the Tape Library
Application Selection panel.
3. When the library list is displayed, type the line operator command LISTVOL
next to the library name or names for which you need a volume listing.

When option 1, SAVED LIST, is selected, you enter the name of the saved list in
the LIST NAME field under option 1 GENERATE FROM A SAVED LIST. A
previously saved list is displayed.
When option 2, NEW LIST, is chosen, a new list is built using the selection criteria
you described in the GENERATE A NEW LIST FROM CRITERIA BELOW data
columns. z/OS DFSMS Using the Interactive Storage Management Facility describes all
the columns in the Mountable Tape Volume Selection Entry Panel. Complete the
following fields for option 2 (default):
VOLUME SERIAL NUMBER
Enter a full or partial serial number of the volume or volumes to include in the
list. The default value is an asterisk. The volume serial number must consist
entirely of upper case alphabetics A–Z and numerics 0–9.
To include a single volume, enter a fully qualified volume serial number of 1
to 6 characters: VOLUME SERIAL NUMBER ===> SYS001
For a partially qualified volume serial number, use asterisks as global volume
serial number characters or percent signs as place holders. For example, to
include a range of volumes, enter a partially qualified volume serial number
by using one or two asterisks as global volume serial number characters:
VOLUME SERIAL NUMBER ===> T*9*
Use a single asterisk to specify all mounted volumes that fit your other
selection criteria: VOLUME SERIAL NUMBER ===> * This field is primed
with the last value used. The default value is an asterisk.
LIBRARY NAME
Enter the 1 to 8 character name of a tape library, or a partially qualified name.
This field is primed with the last value used. The default value is an asterisk.
STORAGE GROUP NAME
Enter the 1 to 8 character name of an SMS storage group, in the same way as
you would for a volume serial number. This field is primed with the last value
used. The default value is an asterisk.
RESPECIFY VIEW CRITERIA
This field is used to specify whether or not to invoke the Mountable Tape
Volume View Entry panel before displaying the sort or list panel. Values are Y
or N.
RESPECIFY SORT CRITERIA
This field is used to specify whether or not to invoke the Mountable Tape
Volume View Sort panel before displaying the list. Values are Y or N.
Final Step: Generating the List
After entering the information you want on the Mountable Tape Volume Selection
Entry panel, you are ready to generate the list. Press ENTER to display the
volumes that meet your selection criteria. If you specified view or sort criteria, the
VIEW or SORT panels are displayed before the volume list.

Creating a List of Tape Libraries
Generating a tape library list allows you to audit all the volumes within the
selected tape library. You may generate a library list in much the same way that
the volume list is created. Follow the same directions as in “Final Step: Generating
the List” on page 350 to generate the library list.
Once you have generated the library list, the tape library list panels are displayed
(Figure 65 through Figure 69 on page 357). See “Displaying Tape Library
Attributes” on page 336 for descriptions of the attributes on these panels.

Viewing and Sorting a List
You can sort and tailor a list with the View, Sort, and Hide options on the
Mountable Tape Volume List or the Tape Library List panels. z/OS DFSMS Using
the Interactive Storage Management Facility discusses the View, Sort, and Hide
options in more detail.

z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
Auditing Volumes in an Automated Tape Library
From the ISMF panels, you can use the AUDIT line operator or the ISMF AUDIT
command to verify the location of the tape volumes in your tape libraries.
AUDIT provides three auditing scopes:
v Single volume audit (invoked by the AUDIT line operator)
v Volume list audit (invoked by the AUDIT command)
v Library audit (invoked by the AUDIT line operator
Note: The audit functions are not supported in an MTL.
AUDIT can be invoked as an ISMF line operator on the Mountable Tape Volume
List panel (single volume audit) or from the Tape Library List panel (library audit).
AUDIT can also be invoked as an ISMF command to audit all eligible volumes on
the Mountable Tape Volume List (volume list audit). ISMF is an important part of
the audit scheme because it allows you to start with an entire tape volume list, and
then by using sorting and filtering capabilities, you can reduce that list to a subset
of volumes; for example, all the volumes in a single storage group. You can then
use the AUDIT command to request an audit of all volumes in that subset list.
Note: In an environment with multiple systems at different z/OS software levels
but sharing a common TCDB, library audits should be performed on the
system with the highest software level of z/OS. A library audit on a lower
level z/OS software level does not include higher release level volumes if
they are media types unknown to the lower level software.
You may want to use the following criteria when filtering a volume list:
v Fully or partially qualified volume serial number
v Fully or partially qualified storage group name
v Fully or partially qualified library name
v Other criteria using ISMF VIEW, SORT, and HIDE
Before scheduling an audit request for an automated tape library, ensure that the
following criteria is met:
v The library must be defined in the SMS configuration.
v The library must be online, operational, and not pending offline.
v For an automated tape library dataserver, the library must not be in manual
mode and the vision system must be operative.
Verifying External Volume Labels Using the ATLDS Vision
System
The library vision system on an ATLDS verifies the external label on the volume at
the physical location specified in the library manager data base. The cartridge is
not mounted and read, only the external label is verified. The following actions are
performed when an audit is requested against volumes in an automated tape
library dataserver:
v The system verifies that the tape volume has an entry in the library manager.
v The visual system verifies that the tape volume is in its assigned location in the
automated tape library dataserver.
v The vision system verifies that the external cartridge label of the tape volume is
present and readable.
v The system verifies that the tape is accessible in the automated tape library
dataserver.
Appendix B. Using ISMF Panels to Define and Monitor Your Configuration
359
Verifying VTS Logical Volume Entries in the Library Manager
Because a logical volume may or may not yet exist on a physical piece of media (a
stacked volume), the following actions are performed when an audit is requested
against logical volumes in the virtual tape server.
v The system verifies that the logical volume has an entry in the library manager.
v If the logical volume resides on a physical piece of media, the vision system
verifies that the physical volume is in its assigned location in the automated tape
library dataserver.
v The vision system verifies that the external cartridge label of the physical
volume is present and readable.
Verifying Volumes in a 3584 Tape Library
Audit verification of a physical volume or of a logical volume whose virtual tape
server resides in a 3584 tape library does not result in the library physically
scanning the volume's label. Instead, the library manager queries the 3584 Library
database to confirm that it has the volume in the expected cell. For a logical
volume, the physical volume on which the logical volume resides is queried.
Invoking the Audit Command/Line Operator
To perform a volume list audit from the MOUNTABLE TAPE VOLUME LIST
panel, use the AUDIT command on the command line of the ISMF panel.
To perform a library audit from the TAPE LIBRARY LIST panel use the AUDIT
line operator next to the tape library name. When you specify a library audit, all
volume serial numbers known to that library by the host are audited.
Because a library audit and a volume list audit might take a long time to complete,
a confirmation panel is displayed whenever these audits are requested. This panel
gives you the opportunity to confirm or cancel the audit request. To confirm, type
in Y, then press ENTER. See Figure 71 for the Confirm Audit Request panel.

Figure 71. Confirm Audit Request Panel
Note: The audit operation can be a lengthy process. During AUDIT execution,
other activity in the library is not quiesced and AUDIT requests are
prioritized lower than other requested functions. It may take several hours
360
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
for you to receive notification that a full library audit or an extensive
volume list audit has completed. Therefore, when scheduling an audit, take
work load and time factors into consideration.
Receiving Audit Completion Messages
When you invoke the AUDIT line operator or AUDIT command successfully,
AUDIT SCHEDULED is displayed on the Mountable Tape Volume List. A
completion message indicating success or failure of the audit is sent to the storage
administrator. In the case of using the AUDIT line operator, if the volume is
successfully scheduled for an audit, the volume has *AUDIT displayed in the line
operator column. Audits that are not successfully scheduled have ¬AUDIT or
?AUDIT in the line operator column.
When you receive an audit completion message, you can use the REFRESH
command to update the MOUNTABLE TAPE VOLUME LIST or the TAPE
LIBRARY LIST with the same selection criteria. The results of the audit are shown
in the VOLUME ERROR STATUS column and you also receive a message with the
error results.
Identifying Audit Discrepancies
If discrepancies are found when performing an audit, they are related to you by
the following means:
v Scheduling error messages for full library audits are issued to your TSO logon
session, unless the scheduling error occurred before any volumes from the
library being successfully scheduled and that error was severe enough to
prevent any other volumes in the library from also being scheduled. This early
detected severe error is reported on the ISMF panel through the help facilities
offered by ISMF. Messages contain the volume serial number (if known) of the
volume for which the error was found and text that indicates the type of error
found in attempting to validate an audit request.
If the scope of the audit is volume list or single volume, scheduling errors are
not reported to your TSO logon session. These errors are indicated on return to
the ISMF panel from which the AUDIT request was initiated and can be
interrogated by using the message and help facilities offered through the ISMF
panels. See z/OS DFSMSdfp Storage Administration for more information about
the ISMF message and help facilities.
v Errors incurred while attempting to perform the physical audit for any of the
three audit scopes, (single volume, volume list, or full library) are reported to
your TSO logon session.
v After auditing a volume, the error status field (ERRSTAT) of the tape
configuration database (TCDB) volume record is updated.
v As notification that the audit has been completed and that the error status fields
can be reviewed, a completion message is sent to you.
Note: The volume error status field contains only the last error found; no
history is kept.
Detecting Software Errors
If a software error (such as an internal label error) exists before an AUDIT and the
AUDIT detects no errors, the software error is retained and not updated. Only one
value is retained in the volume error status field. No history of errors is
maintained for this field. If no software error exists before the AUDIT, the volume
error status field is updated with the new volume error status.
Appendix B. Using ISMF Panels to Define and Monitor Your Configuration
361
No attempts are made to fix the problems at the time of detection because, based
on the error found, the software is unable to determine exactly what the corrective
action should be.
If you end the TSO session before the audit completes, messages are stored in the
broadcast data set and are displayed the next time you initiate your TSO session.
Altering the Volume Record
ISMF allows you to alter the use attribute, storage group, shelf location, and owner
information of a single tape volume or a volume list through the use of the ALTER
line operator or the ISMF ALTER command. These commands are used from the
Mountable Tape Volume List panel (see Figure 60 on page 351).
ISMF is an important part of the alter scheme when used in conjunction with the
ALTER command because it allows you to start with an entire tape volume list,
and then by using sorting and filtering capabilities, you can reduce that list to a
subset of volumes; for example, all the volumes in a single storage group. You can
then use the ALTER command against the subset list to change information for all
the volumes on the list at once. In an ATLDS, you can also use the ALTER
command to take the volume out of the error category in the library manager
inventory.
Invoking the Alter Command/Line Operator
When you invoke the ALTER command on the MOUNTABLE TAPE VOLUME
LIST panel, the same values for use attribute, storage group, shelf location, and
owner information are assigned to ALL the volumes in the list.
The Mountable Tape Volume Alter Entry Panel (Figure 72) is displayed.

Validating New Values through ISMF
ISMF validates the NEW VALUE input for the use attribute to allow only ‘P’ or ‘S’.
The NEW VALUE input for storage group is validated on the same selection entry
panel; however, blanks are acceptable in this field.
ISMF does not validate the existence of the storage group in the active
configuration; however, if the tape volume is library-resident, OAM provides the
validation to ensure the following:
v The volume’s storage group is defined in the current ACDS as a tape storage
group.
v The volume’s library is defined in the specified storage group.
v The volume’s library is defined in the current ACDS as a valid tape library.
Note: If the tape volume is shelf-resident, only the first check is made.
Detecting Errors with New Values
If OAM detects an error in any of the above conditions, neither the use attribute
nor the storage group is changed. Shelf location and owner information are not
prevented from being altered even though an error is detected.
When an error occurs during the ALTER function, a message is stored in the
message history for the entry. The storage administrator can issue the message line
operator to obtain the error information.
Confirming an Alter Request
When the storage administrator presses ENTER to perform the alter, the Confirm
Alter Request panel (Figure 77) is immediately displayed. The number of volumes
that will be altered is displayed. The storage administrator must confirm the alter
request by changing N to Y and pressing ENTER.

Changing the Use Attribute from Private to Scratch
If the storage administrator uses the ALTER command to specify a NEW VALUE
of scratch for the use attribute and any of the volumes on the list are private with
an expiration date that has not yet passed, the Private to Scratch Confirmation
Panel (Figure 78) is displayed for each volume whose expiration date has not yet
passed.
Note: When DFSMSrmm is installed, any attempt to alter the use attribute from
private to scratch will be rejected.

v The storage group name is set to *SCRTCH* in the TCDB.
v The expiration date in the TCDB is blanked out.
v The volume error status is reset to NO ERROR in the TCDB.
v The library manager category of the cartridge is changed from private to scratch
(ATLDS only).
Note: The change use attribute installation exit (CBRUXCUA) is invoked whenever
there is an attempt to change the use attribute for a tape volume. It may
override the request or change the values. See “Change Use Attribute
Installation Exit (CBRUXCUA)” on page 211 for more information on this
installation exit.
Changing the Use Attribute from Scratch to Private
When the ALTER line operator or the ALTER command changes the use attribute
for a single tape volume or a list of tape volumes to private, the following items
are performed:
v The use attribute is changed to P in the TCDB.
v The volume error status is reset to NO ERROR in the TCDB.
v The category of the cartridge or cartridges is changed from scratch to private
(ATLDS only).
366
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
The changes to the TCDB volume record are performed immediately. When the
line operator or command is complete, the user is returned to the Mountable Tape
Volume List panel with the appropriate success or failure message. If the volume
or volumes were successfully changed, the ISMF REFRESH command may be used
to display the new values in the tape volume record.
Ejecting a Volume from a Tape Library
A single library-resident tape volume can be ejected from a tape library dataserver
through the use of the ISMF EJECT line operator. The EJECT line operator is used
from the MOUNTABLE TAPE VOLUME LIST application (Figure 60 on page 351).
The line operator is typed next to a specific volume, causing the volume to be
ejected from the tape library.
Note: For logical volumes in the fast ready category at the VTS, ejecting the
volume deletes the logical volume from the VTS. If a logical volume is not
in the fast category, the volume must be exported from the library.
Specifying Optional EJECT Line Operator Parameters
There are two optional parameters associated with the EJECT line operator. The
first optional parameter specifies K for KEEP or P for PURGE. This parameter
determines whether the tape volume record should be kept or deleted in the TCDB
once the tape volume is ejected. No matter which disposition is specified, the
volume record in the library manager inventory is deleted. If the parameter is not
specified, the EJECT DEFAULT for the tape library is used. This parameter can be
overridden by the cartridge eject installation exit (CBRUXEJC), which is invoked to
approve or deny the EJECT request. See “Cartridge Eject Installation Exit
(CBRUXEJC)” on page 232 for more information regarding this installation exit.
The second optional parameter B specifies that the tape cartridge is to be placed in
the high-capacity output station instead of the convenience output station. If this
parameter is not specified or the high-capacity output station is not configured, the
cartridge is placed in the convenience output station.
This keyword is only valid for automated tape library dataservers. The keyword is
ignored for tape volumes ejected from a manual tape library.
Note: The EJECT line operator is only valid for tape volumes that are
library-resident.

Peer-to-Peer VTS data. The 3494 Peer-to-Peer VTS
data (PTPDATA) function allows an installation or
application to obtain operational mode settings and
device-related information from the PTP VTS library.
Peer-to-Peer VTS library. Multiple 3494 VTS
subsystems and their associated tape libraries coupled
together to form one subsystem and library image to
the host. See also Virtualization Engine.
Peer-to-Peer VTS mode control. The 3494 Peer-to-Peer
VTS mode control (PTPMC) function allows an
installation or application to change current operating
modes of the library.
performance scaling. Formatting a tape so that less
than its full capacity is used. Formatting a tape to its
optimal performance capacity decreases the amount of
time required to access the data on the tape. A tape that
is formatted to its optimal performance capacity can
later be reused and formatted to its full capacity.
Performance scaling only applies to MEDIA5 and
MEDIA9 tape cartridge media.
performance segmentation. Formatting a tape into
two segments. The fast segment is written to first,
providing a performance benefit. Once the fast segment
is filled, the other segment is used, which has slower
access. Performance segmentation applies to MEDIA5
and MEDIA9 tape cartridge media.
physical library. In relationship to a virtual tape
server, a physical library is a hardware enclosure
consisting of one or more virtual tape server libraries
with each virtual tape server being identified to the
host as a separate library. Restrictions by the library
manager may be set on an individual library basis or
on a physical library basis as is the case with import.
physical volume. A volume that has a one-to-one
association with physical tape media and which is used
directly by MVS applications. It may reside in an
automated tape library dataserver or be kept on shelf
storage either at vault sites or within the data center
where it can be mounted on stand-alone tape drives.
Glossary
377
physical volume pool. A set of stacked volumes in the
VTS that may be grouped together because of common
characteristics.
policy action. Actions defined outboard at the tape
library for policies that are assigned to tape library
volumes as volume attributes. Specific types of actions
are defined to policy types (storage group, storage
class, management class, or data class).
policy construct. Name of an SMS construct that is
used outboard as a policy name and is assigned to a
library-resident tape volume. Policy actions are defined
at the library and are not known to the host.
private tape volume. A volume assigned to specific
individuals or functions.
PTPDATA. Peer-to-Peer VTS data.
PTPMC. Peer-to-Peer VTS mode control.
PtP VTS. Peer-to-Peer Virtual Tape Server.
R
recording format. For a tape volume, the format of
the data on the tape; for example, 18, 36, 128, 256, 384
tracks, EFMT1 (Enterprise Format 1), EFMT2
(Enterprise Format 2), EEFMT2 (Enterprise Encrypted
Format 2), EFMT3 (Enterprise Format 3), or EEFMT3
(Enterprise Encrypted Format 3).
reentrant. The attribute of a program or routine that
allows the same copy of a program or routine to be
used concurrently by two or more tasks.
removable media. Volumes that can be removed from
the hardware devices where they are read and written,
for example, tape cartridges and optical disks.
System Modification Program/Extended. Basic tool
for installing software changes in programming
systems. It controls these changes at the element
(module or macro) level, which helps protect system
integrity.
SMSplex. A group of one or more systems that share
a common set of SMS control data sets: the active
control data set (ACDS) and the communications data
set (COMMDS).
T
tape cartridge. A case containing a reel of magnetic
tape that can be put into a tape unit without stringing
the tape between reels.
tape configuration database (TCDB). An ICF user
catalog marked as a volume catalog (VOLCAT)
containing tape volume and tape library records.
tape library dataserver. A set of related tape drives
and the set of tape volumes which may be mounted on
those drives.
tape storage group. A tape storage group is a
collection of tape volumes which contain private user
data. Each volume normally resides in one of up to
eight tape libraries which are associated with the tape
storage group. A volume becomes part of the tape
storage group when it is mounted to satisfy a scratch
volume request for the storage group, or when it is
entered into one of the tape libraries and assigned to
the storage group by the cartridge entry process. The
volume is removed from the storage group when it is
returned to scratch after the data sets on it have
expired.
tape volume. A reel of magnetic tape.
S
TCDB. Tape configuration database.
SCDS. Source control data set.
scratch pool. The collection of tape cartridges from
which requests for scratch tapes can be satisfied.
scratch tape volume. An unassigned tape volume.
shelf-resident tape volume. A tape volume that
resides outside of a tape library.
stacked volume. A volume that has a one-to-one
association with physical tape media and which is used
in a virtual tape server to store logical volumes. A
stacked volume is not used by MVS applications but by
the virtual tape server and its associated utilities. It
may be removed from a virtual tape server to allow
transportation of logical volumes to a vault or to
another virtual tape server.
378
Storage Management Subsystem. See DFSMS.
TCDBplex. A group of one or more systems or
sysplexes, or both which share the same tape
configuration database. The individual systems in the
TCDBplex share access to one or more tape library
dataservers, and to a common pool of scratch volumes
in each tape library. They may also share access to the
set of private volumes in each tape library.
TDSI. Tape device selection information.
V
vary offline. To change the status of a tape library or
a tape drive from online to offline. When a library or
drive is offline, no data may be accessed on tape
volumes through the offline drive or the drives in the
offline library.
z/OS V1R11.0 DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries
vary online. To change the status of a tape library or a
tape drive from offline to online.
virtual tape server (VTS). This subsystem, integrated
into the IBM TotalStorage Enterprise Automated Tape
Library (3494 or 3584), combines the random access and
high performance characteristics of DASD with
outboard hierarchical storage management and virtual
tape devices and tape volumes. See also Virtualization
Engine.
Virtualization Engine. The IBM System Storage
TS7700 Virtualization Engine (3957). Members of the
TS7700 product family include the TS7740
Virtualization Engine (3957-V06) as well as the
disk-only TS7720 Virtualization Engine (3957-VEA). It
replaces the IBM TotalStorage 3494 Virtual Tape Server.
The existing virtual tape server (VTS) concepts also
apply to the virtualization engine.
virtual volume. A tape volume that resides in a tape
volume cache of a virtual tape server. Whether the
volume resides in the tape volume cache as a virtual
volume or on a stacked volume as a logical volume is
transparent to the host.
vision system. An intelligent pattern recognition
system that consists of a camera and lamps mounted
on the gripper assemblies, the vision system controller,
and the vision monitor. The vision system scans the
external labels on cartridges to provide positive
cartridge identification.
volume attributes. Attributes of volumes in a tape
library. These include volume category, type of volume,
and assigned policy construct names.
volume catalog. An ICF user catalog containing the
volume and library entries associated with tape
libraries.
volume category. In software, a category at the library
in which the host software places volumes with a
common attribute.
volume record. A record containing information
related to a volume, such as volume serial number,
library name, and storage group. The volume record
resides within the tape configuration database.
volume type. Uniquely identifies the type of volume.
Tape volume types include physical, logical, stacked
logical, imported logical, and exported logical volumes.
VTS. Virtual tape server, such as the IBM TotalStorage
3494 Virtual Tape Server. See also Virtualization Engine.
