Chapter
1
Introduction
This chapter describes the features of the expansion and base modules of the
MiniLibrary System, including Storage Architecture, SCSI Interface, Bus
Performance, and Physical Configuration/Expansion Options.
The MiniLibrary System is an expandable, modular tape library system
combining DLT technology drive with advanced robotics. The MiniLibrary
System is designed for high duty-cycle on-line and near-on-line applications,
such as hierarchical storage management (HSM). It is a superior performer in
high-volume backup and archival service as well.
Modules
Two types of modules comprise the MiniLibrary System:
■
Expansion Unit (Master)
■
MiniLibrary (Base Module)
The MiniLibrary System consists of one Expansion Unit and up to five
MiniLibrary base modules stacked in a rack. The Expansion Unit can move
media freely between itself and Base Modules via the system’s roboticallycontrolled pass-through mechanism.
In a MiniLibrary System, you can combine modules to provide the right
combination of capacity and performance to meet your present storage
requirements. Compaq’s MiniLibrary storage architecture lets you add
modules to optimize throughput and capacity as your needs change.

MiniLibrary Storage Architecture
When connected as a system, the robotics in the MiniLibrary Expansion Unit
act as commanded by the host computer(s). The host(s) need no knowledge of
the internal geometry of the system, or of the actions or capabilities of the
Base Modules.
The Expansion Unit presents to the host(s) a single SCSI medium changer
device with a single SCSI Medium Transport element, a number of SCSI
Storage elements equal to the total number of cartridge magazine slots, a
number of SCSI Import/Export elements as specified by the user during
configuration of the Expansion Unit, and a number of SCSI Data Transfer
elements equal to the total number of drives in the system.
Flexibility
Compaq’s MiniLibrary storage architecture is uniquely suited to growing
storage needs. Its flexible library robotics system enables you to start with a
system configured to your present requirements, confident that as your storage
needs evolve, you can easily modify the MiniLibrary by adding modules and
extending the pass-through mechanism. Add drives for faster performance or
magazine space for greater capacity, as needed. Then just turn on the power,
and immediately the system updates the system map so the host is informed of
the expanded capability.
Multi-Server Data Sharing
A host computer with a SCSI controller connected to a bus is a SCSI Initiator.
The Expansion Unit is a SCSI Target. SCSI rules permit multiple Initiators on
a single bus. Therefore, with the proper host software, it is possible to connect
multiple hosts to a single Expansion Unit over a single SCSI bus. This allows
multiple hosts to operate the library robotics, loading and unloading cartridges
as each host requires.
In a system with many drives, it is desirable to use multiple SCSI buses for the
drives, so the data transfer rate of the drives is not limited by bus bandwidth.
In a large, high-performance system, drives may be connected to separate
hosts. Using special software, one of the hosts can act as a master server,
processing all robotics commands. In this way several hosts may share a
common data base.

Introduction 1-3
The Expansion Unit
Description
The Expansion Unit integrates the robotics in the individual modules into a
single coordinated library robotics system. The Expansion Unit performs and
maintains an inventory of all media present in the system, including bar code
data. All necessary system control operations may be performed from the
control panel of the Expansion Unit, as well as from the host via software. The
SCSI interface for the library robotics is designed for high-speed
communication with the host, and Fast/Wide SCSI configurations.
In addition to its system control functions, the Expansion Unit has a 16cartridge magazine with a rugged random access robotic mechanism. The
module robotics moves cartridges between the pass-through mechanism and
any of the 16 cartridge storage locations.
The user may designate a magazine in one of the base modules as a mail slot
for inserting or removing one or more single cartridges, which implements the
SCSI Import/Export commands.
NOTE: A magazine that has been reserved for Import/Export service may not be used for
data storage.
The Base Module
Description
The Base Module has one or two TZ89 tape drives and a 10-cartridge
magazine with a rugged random access robotic mechanism.
Models
The TL891 using one or two TZ89 series drives, also use the DLTtape IV
cartridges, which provide a native capacity of 35 GB per cartridge. All models
can also read and write DLTTape III and DLTtape IIIxt cartridges. Both read
and write densities are selectable from the front panel, and under SCSI control
from the host.

SCSI Interface Configurations
Systems are equipped with TZ89 drives use a Fast/Wide SCSI interface using
high-density 68-pin D-series connectors. The section on SCSI Interfaces in
Chapter 3, Installation, describes the available interface options.
SCSI Bus Performance Considerations
Data Transfer Rate
The data transfer rate of the MiniLibrary is dependent on the type and number
of drives and on the SCSI bus configuration. The bandwidth of the SCSI bus is
limited. As a result, the transfer rate of exceptionally fast drives such as the
TZ89 can be limited by sharing a SCSI bus with another disc drive on tape.
Drives
With a standard SCSI interface, modules equipped with TZ89 drives have a
native data transfer rate of 5.0 MB/second, 10 MB/sec for two drives. The
rates for compressed data are dependent on compression ratio, record size,
data type, and other system parameters, but averages approximately 1:7.
Internal Cabling Configuration
The MiniLibrary System is wired in an independent-bus SCSI configuration.
That is, the robotics and each of the drives has its own SCSI bus. SCSI
jumpers are available for those applications requiring that some combination
of drives and robotics be daisy-chained to a single SCSI bus. These
configurations are described in more detail in the section on SCSI Interfaces in
Chapter 3, Installation.

Introduction 1-5
Physical Configuration
The Expansion Unit must be mounted at the top of the stack, which places its
control panel at a convenient height. The control panels of the Base Modules
are of secondary importance, as they serve mainly to help localize system
failures. When installed, the motor drive assembly of the pass-through
mechanism is directly behind the Expansion Unit.
Base modules may be installed anywhere below the Expansion Unit, in any
order. There may be a slight performance advantage in making the Base
Modules contiguous, but gaps are permitted. The size of a gap is limited by the
fact that each gap must be bridged by some number of 7” pass-through
mechanism track sections. For safety, available cover plates should be
installed on all pass-through mechanism sections that are not connected to
MiniLibrary modules.
The Expansion Unit senses the position of each module during initialization at
power-up. Even if there are gaps between modules, the system will operate
correctly. If you plan to leave gaps between modules, be sure to order
additional pass-through mechanism track segments and cover plates equal to
the length of the gap.
System Expansion
A MiniLibrary System may be expanded in capacity and performance by
adding or removing TL891 modules. Associated with the Expansion Unit and
each of the Base Module(s) is a section of the pass-through mechanism.
System firmware integrates all of the robotics of these system modules with
that of the pass-through mechanism into a single high-performance library
robotics system.

Magazine Security Lock
The Magazine Security Lock is a key-operated switch on the front panel of
each module. It can be used to prevent inadvertent removal of the cartridge
magazine.
Power Supply
The AC Power switch is located on the front panel of the module. The
autoranging power supply will adjust automatically to either of two operating
voltage ranges. The ranges are 100-120 VAC and 200-240 VAC. The power
supply is capable of operating at 50 or 60 Hz without any adjustment or
modification. AC power is supplied to the power supply by a single IECcompatible socket that can be connected to any properly grounded outlet.
Tape Cartridge Magazines
The 10-cartridge and 16-cartridge magazines are removable from the front
panel, but may be protected from tampering by any of three means: 1) a keyoperated Magazine Security Lock which must be unlocked before the
magazine can be removed, 2) an electronic combination lock operated by
using buttons on the Expansion Unit control panel, and 3) issuance by the host
of a SCSI ‘Prevent Medium Removal’ command. The rugged carbon-fiberreinforced polymer magazine fits into an extruded track, which assures precise
positioning with respect to the library robotics. A 10-cartridge tape magazine
is shown in Figure 1-3. Insertion and removal of the magazine is described in
Chapter 2, Operation.

Advanced Design Features
The MiniLibrary System incorporates many significant improvements in tape
drive and library design. One of the most important is the use of highly
reliable DLT technology, with media rated by the media manufacturer at better
than 1,000,000 head passes.
Embedded Diagnostics
The MiniLibrary System and each of its modules provide three levels of
embedded diagnostics. The Power-On Self Test (POST) performs various
verification tests on the system’s configuration and host interface and device
control functions, as well as memory tests, at power-up. The second level of
diagnostics is the User Diagnostics, which provide for displaying and
changing configuration options. The third level, Customer Engineer (CE)
Diagnostics, include advanced diagnostics to be used by Customer Engineers
for servicing the MiniLibrary System. Both the User Diagnostics and the CE
Diagnostics may be selected from the front panel.
User Diagnostics are described in greater detail in Chapter 3, Installation.
Error Checking
Drives used in the MiniLibrary System apply a 16-bit parity check to each
record, a 64-bit CRC to each 4 kb of data, and Reed-Solomon error correction
code overall. In addition, there is an internal parity check on the data buffer.
Compression
MiniLibrary System drives use the standard Digital Lempel-Ziv (DLZ) data
compression algorithm.
Capacity
A Base Module with its 10-cartridge magazine and a single Expansion unit
with its 16-cartridge magazine offers the formatted capacities shown in Table
1-1.

Operation 2-3
Power Switch
The power switch controls the supply of AC power to the module. It is set into
a recess in the front panel to prevent accidental operation. Press 1 to turn the
module ON and 0 to turn the module OFF.
NOTE: The Expansion Unit must be turned on after or simultaneously with the Base
Module(s). If this is not done, the Expansion Unit may not be notified of the presence of
one or more of the Base Modules.
Control Panels
The Expansion Unit control panel, shown in Figure 2-2, consists of three LED
indicators, a four-line by 20-character backlit LCD display, and four buttons.
The Base Module control panel, shown in Figure 2-3, has four LED indicators,
Expansion Unit Indicators
There are three LED indicators on the Expansion Unit control panel, labeled
Ready (green), Alert (yellow), and Fault (red), that serve as follows:
■
Ready (green) - illuminates when the system is ready to accept
commands, either from the control panel or from the host computer. The
Ready indicator goes out when you enter the Menu Mode.
■
Alert (yellow) - indicates that a fault or some other matter that requires
attention has occurred in one of the modules in the system. Line 2 of the
display blinks the number of the module where the fault has occurred.
The control panels of the indicated module may give a further indication
of the cause of the alert. Often, when the Alert LED is lit, a Fault LED
is illuminated on one or more of the Base Modules as well.
■
Fault (red) - indicates that a fault has occurred in the Expansion Unit, or
that the magazine door is unable to close. When the red LED is
illuminated, a Fault Screen appears on the LCD display. The Fault
Screen is described later in this chapter. A list of fault symptom codes
(FSC) and error recovery procedures (ERP) appears in Chapter 6,
Diagnostics and Troubleshooting.

the Enter button. Table 2-1 describes the effect of each of the four buttons
under various conditions.
The three most important things you need to know about the buttons are:
1. To enter the Menu Mode and display the Main Menu from the Default
Screen, press the Enter button.
2. To return to the Main Menu from a submenu, press the Escape button
repeatedly until the Main Menu appears. Pressing the Escape button
while the Main Menu is displayed exits the Menu Mode and returns you
to the Default Screen. The Default Screen is shown in Figure 2-6; the
Main Menu is shown in Figure 2-10.
3. To display the Show Status Menu only without entering the Menu
Mode, press the Escape button at the Default Screen. The system
remains online.
NOTE: When you enter the Menu Mode at the Expansion Unit, the Ready light on
that module goes out. This means that the MiniLibrary system is off-line, and the
system responds to all commands from the host with a SCSI ‘Not Ready’ until you
exit the Menu Mode and the Ready light goes on. When you enter the Menu Mode
at any of the Base Modules, the Ready light on that module goes out. This means
that the individual module is off-line, and the system responds to all commands
from the host pertaining to that module with a SCSI ‘Not Ready’ until you exit the
Menu Mode and the Ready light goes on.

Front Panel and Media Locks
To avoid accidental interruption of system operation by entering the Menu
Mode or removing cartridges while the host is accessing the system, the front
panel and the media for each module may be electronically locked. When the
front panel of the Expansion Unit is locked, you can only enter the Menu
Mode after entering a 4-digit code. That is, when the Default Screen is
displayed, pressing the Enter button does not invoke the Menu Mode until you
enter the code. The front panel of a Base Module cannot be unlocked without
using the Security submenu on the Expansion Unit to unlock it.
All Base Module front panels are locked by default when connected to a
Expansion Unit.
Media located in any or all modules may be locked and unlocked using the
Security submenu on the Expansion Unit. When the media are locked, you can
only remove media after unlocking the module from the Expansion Unit using
the Security submenu.
Procedures for locking and unlocking front panels and media are described
later in this chapter.
Starting the System
NOTE: When turning on power to the MiniLibrary, power must be applied to the
Expansion Unit either simultaneously with or after the other modules. If the Expansion Unit
is powered on first, its inventory of modules may be incorrect, and the contents of some
or all of the modules will be inaccessible to the system and to the host.
Display Messages
The display on the control panel is capable of displaying four lines of 20
characters each, to allow the use of easy-to-understand messages. Many of
these messages and their functions are described in this chapter. Those
displays that are described in other chapters are cross-referenced here as well.

The fourth line in a Base Module is the magazine map. Numbers 16-25 in
Figure 2-8 represent the map numbers of the cartridge slots. In this case, we
have a 10-slot magazine in the first position below the 16-slot Expansion Unit.
These numbers vary with the position of the module within the system and
magazine size. If no magazine is installed, line 4 says ‘No Magazine'. The
boxes present on this line indicate that a cartridge is present in the
corresponding slot of the magazine. An underline means that there is no
cartridge present in that slot.

press the button, three things happen:
The list scrolls down one item (only line 2 scrolls).
A appears on the right of line 1 of the display. This indicates that there is
one or more items above the item displayed on line 2.
The * at the left of line 2 disappears. This is because the * indicates the current
selection or the default selection, and you have scrolled the default selection
offscreen, and haven’t yet selected an item from the list.
NOTE: The contents of the lists on line 2 and line 4 will vary as follows:
Initial Screen - ‘From’ Line
The list on line 2 in Figure 2-26 (the ‘From’ line) will include every drive and
every magazine slot (including mail slots) that has a cartridge in it (you can’t
get a cartridge from a slot or drive that is empty).
Initial Screen - ‘To’ Line
The list on line 4 of Figure 2-26 (the ‘To’ line) will include all of the valid
destination choices, that is, drives and slots that are empty (you can’t put a
cartridge into a slot or drive which already has one in it).

Inserting and Removing Cartridges
When inserting cartridges, be sure that the slot you intend to use is not already
reserved in the system map for a cartridge in a drive. The best way to avoid
conflicts is to unload all drives, either through your host computer software or
by using the Load/Unload command on the Main Menu, described in the
previous section.
The tape magazine must be removed from the module in order to insert or
remove cartridges. To insert or remove the magazine, the following conditions
must be met.
The Magazine Security Lock must be unlocked, using the key supplied with
the module. Refer to Figure 2-31. When the Magazine Security Lock is
locked, the Unlock/Open button has no effect. If the module is installed in a
reasonably secure environment, you may elect to leave the Magazine Security
Lock in the unlocked position.
Media locking on the Security Menu must be disabled. Refer to Figure 2-17.
The host computer must allow medium removal. The host computer can
enable or disable the Unlock/Open button using the SCSI Prevent Allow
Medium Removal command. When you press the Unlock/Open button, the
message ‘Magazine Locked” will be displayed.
The Expansion Unit must be ready, and not actually executing a command.
IMPORTANT: When you enter the Menu Mode, the Ready light goes out. The magazine
cannot be inserted or removed unless the Ready light is on. To remove the magazine
when a failure prevents the Ready light from illuminating, refer to the section entitled
Emergency Magazine Removal.

Tape Requirements
The MiniLibrary System uses ECMA-approved and ANSI proposed-standards
DLTtape cartridges. The DLTtape cartridge is a four-inch square plastic
cartridge. According to the media manufacturer, the cartridge and the medium
are designed to withstand 1,000,000 passes, and to have a shelf life of 30 years
when properly stored.

Operation 2-31
Cartridge Handling and Storage
A DLTtape cartridge should be stored vertically until you select it for use. Do
not expose a cartridge to moisture or direct sunlight. Maintain a clean, dustfree working and storage environment.
If a DLTtape cartridge is dropped:
■
Inspect the cartridge carefully before you insert it into a MiniLibrary
magazine or any drive.
■
Shake the cartridge while listening for the sound of a broken part. Any
rattling sound makes a cartridge unfit for use.
■
Inspect the case for distortion or cracks.
■
Inspect the leader by opening the cartridge door as shown in Figure 243. The leader should be positioned as shown in view (1), and should
protrude at about a five-degree angle from the case. If the leader is out
of position, do not use the cartridge; damage to the drive could result.
Under certain conditions, DLT Tape may stick to the drive read/write head
during operation. Damage to media, failure of commands or batch jobs to
execute, with resulting errors or hangs; failure to unload; apparent need to
swap out the drive.
When tapes are stored in an environment different from that of the drive,
ensure that they are acclimatized, by moving them to a location in close
proximity to the drive before attempting to use them. Ideally, tapes should be
allowed to acclimate for a time equal to the duration of their storage away
from the drive, or 24 hours, whichever is less.
Reports have verified that sticking will occur almost immediately with older,
used tapes which have been stored at 20°C and 75% humidity, when those
tapes are used in a TZ87 drive kept at a higher temperature and lower
humidity. High tape humidity causes sticking from HYDROLYSIS, a
degradation of the tape which can be reversed by storing the tape for a while in
a dry environment Test conditions (cool, damp tapes and warm, dry drives)
have produced “stiction” at will, but other conditions may also cause it.
Remember to acclimatize tapes before use. Long-term storage specifications
are more stringent than those for shorter periods. Cartridges intended for longterm archiving shall be stored in room conditions of 23°C +/-5 (73°F +/-9 at
50% +/-10% relative humidity.

Planning Your Installation
The MiniLibrary System is intended to be mounted in a Compaq Cabinet,
StorageWorks SW500, SW600, SW800 or a standard 19-inch EIA/RETMA
equipment rack with a depth of 24 to 30 inches. Each module is shipped with
EIA/RETMA slides installed. Additional hardware for mounting in Compaq
and SW500, SW600, and SW800 cabinets is included
Every Compaq MiniLibrary System includes:
■
One Expansion Unit
■
One Expandable Pass-Through Mechanism
■
One to five Base Modules, each with one or two TZ89 drives
The Expansion Unit has 16 slots and no drives, and serves as controller of the
MiniLibrary System. The base modules each have 10 slots plus one or two
drives. The Expansion Unit and the Base Module(s) each occupy 7 inches of
rack space height.
The Pass-Through mechanism is composed of a motor drive assembly plus
sections of track whose combined length is equal to the combined heights of
the Expansion Unit plus the Base Modules. One extension section of track is
needed for the installation of each additional MiniLibrary module.
Positioning the Modules
The Expansion Unit must be mounted at the top of the stack, which places its
control panel at a convenient height. The control panels of the Base Modules
are of secondary importance, as they serve mainly to help localize system
failures. When installed, the motor drive assembly of the Pass-Through
mechanism is directly behind the Expansion Unit.
Base modules may be installed anywhere below the Expansion Unit, in any
order. There may be a slight performance advantage in making the Base
Modules contiguous, but gaps are permitted. The size of a gap is limited by the
fact that each gap must be bridged by some number of 7” Pass-Through
mechanism track sections. For safety, available cover plates should be
installed on all Pass-Through mechanism sections which are not connected to
MiniLibrary System modules.
The Expansion Unit senses the position of each module during initialization at
power-up. Even if there are gaps between modules, the system will operate
correctly. If you plan to leave gaps between modules, be sure to order
additional Pass-Through mechanism track segments and cover plates equal to
the length of the gap.

NOTE: The slide extensions, (6) in Figure 3-1, are not enclosed with the Pass-Through
mechanism parts. They are supplied as part of the installation hardware for the slides that
come with each of the modules.
Follow the instructions in the section entitled Mechanical Installation of the
Expansion and Base Modules. After the rack slides and the base modules are
in place, and after the Pass-Through mechanism is assembled, you will install
the Pass-Through mechanism in the rack by attaching the support braces (5) to
the slide extensions (6) using the angle brackets (7) and L-shaped nut plates
(8).

Orientation of Parts During Assembly
To determine the orientation of an extension section, examine the flanges on
the edges of the section, and note that they are dissimilar. Position the section
so that its orientation matches that of the elevator base.
Figure 3-4 shows a typical pass-through mechanism assembly. The motor
drive section always goes on top, and the base section with the idler pulley
always goes on the bottom. Extension sections are mounted between the motor
drive section and the base section. All sections are joined together with tie
bars. For systems up to four modules, two support braces are needed, one
attached to the motor drive and one to the base section. For larger systems, a
third support brace should be mounted near the center of the pass-through
mechanism.
Preparing to Assemble the Pass-Through
Mechanism
You will need a clean, flat work area such as a table or work bench. The
surface should be long enough to support the full height of the pass-through
mechanism. The height is equal to the height of the stack of modules in your
system plus any gaps you intend to include in the stack. Use the following
procedure to assemble your pass-through mechanism.
Assembling the Pass-Through Mechanism
In most cases, you have received a pre-assembled pass-through mechanism. If
its length is correct for your system, turn to the section entitled Mechanical
Installation of the Expansion and Base Modules and continue on to the end of
the chapter. If you need to add sections, please take a few minutes to read this
section and the section entitled Installing the Belt, before proceeding to Adding
to an Existing Pass-Through Mechanism.
NOTE: References to left and right refer to the position of the part when the pass-through
mechanism is assembled and mounted in the rack, as viewed from the front of the rack.
Refer to Figures 3-1 and 3-4.
1. Place the base section, with the inside facing down, overhanging the
right end of the work area, with the bottom plate of the section toward
the right.
2. Place each of the extension sections, with the inside facing down, in a
row aligned edge-to-edge beginning with the base section. The bottoms
of the sections should be toward the right. Omit the motor drive at this
time.

Place pairs of tie bars so that they straddle all of the joints where sections
come together. Be sure that the beveled edge is toward the inside corner of the
sections.
5. Install two M3 x 20 mm Phillips sems screws through each tie bar into
the threaded holes in the flanges of the extrusion sections. Tighten
finger tight only. Insert two M3 x 20 mm sems screws through each tie
bar into the side of the extrusion sections and finger tighten.
6. Firmly press the neighboring sections together while tightening the two
M3 x 20 mm screws through each tie bar into the flanges of the sections.
Alternately tighten the screws into the flanges and those into the sides of
the extrusions to ensure that each tie bar is drawn into the corner of the
extrusion.
IMPORTANT: Be careful not to overtighten these screws.
7. Inspect the joint to see that the sections are well aligned, with minimal
irregularities and gaps.
8. Repeat steps 6, 7, and 8 for each pair of sections. It may be necessary to
use suitable blocks to support the row of sections so that neither the
motor housing nor the bottom flange of the base section touches the
work surface while you are connecting the motor drive section.
9. Center one of the support bars across the rear of the motor drive section
over the holes on the rear surface of that section.
10. Insert two M4 x 20 Phillips sems screws through the holes in the support
brace into the holes in the motor drive section, and tighten.
11. Go to the next section, Installing the Belt.
Installing the Belt
Refer to Figures 3-5 through 3-9.
1. Turn the assembled pass-through mechanism over so that the motor
points upward.
2. Referring to Figure 3-6, locate the tensioner ramp in the base section.
Compress the spring until the hole in the tensioner ramp is aligned with
a hole in the base section. Insert an 0.050” Allen wrench or a paper clip
through the holes. This sets the idler pulley for zero belt tension.
3. Locate the length of toothed belt that was enclosed with the extension
section.

15. To steady the belt block, grasp the belt several inches from the block
and push toward the back of the track until the block is pressed firmly
against the back of the track. While holding the belt with one hand,
compress the springs and swing the car downward until the remaining
wheels are aligned with their groove in the track.
16. While continuing to press the belt block against the back of the track,
release the car so that the stationary wheels engage their groove in the
track.
17. While continuing to press the belt block against the back of the track,
begin to tighten the captive screws. When both screws are partially
threaded into the belt block, release the belt and finish tightening the
screws. Be sure that the block is fully seated against the bracket on the
car. Close and secure the door on the car.
18. Using nylon button rivets, install covers over any exposed pass-through
mechanism sections that are not covered by modules.
NOTE: See Appendix G, Additional Information on Pass-Through Section Covers.
19. Proceed to the section entitled Mechanical Installation of the Expansion
and Base Modules.
Adding to an Existing Pass-Through Mechanism
Before reading this section, it may be helpful to familiarize yourself with the
parts and procedures by reading the two preceding sections. To add to an
existing pass-through mechanism, you must first partly disassemble it, then
make the necessary changes as described in the preceding sections. Use the
following procedure for disassembly.
1.
Locate the covers over the drive motor section and the base assembly. Note that the
covers are held in place by nylon button rivet fasteners. Using a suitable thin-bladed
tool, pry up the cover until the fasteners can be removed. Set the covers aside, and save
the fasteners for re-use.
2.
Place the pass-through mechanism on a suitable work surface with the motor at the left
and pointed upward. Referring to Figure 3-9, open the door of the car to gain access to
the captive screws. Do not remove the door. Loosen the captive screws until they are
disengaged from the belt block.
3.
Grasp the closed side of the car and pull it toward you so as to compress the springs
underneath the car. When the wheels on the closed side are clear of the track, lift the
car from the track and set it aside.

4.
Referring to Figure 3-6, locate the tensioner ramp in the base section. Compress the
spring until the hole in the tensioner ramp is aligned with a hole in the base section.
Insert an 0.050” Allen wrench or a paper clip through the holes. This sets the idler
pulley for zero belt tension.
5.
Referring to Figure 3-8, loosen the four screws on the belt block far enough to pull the
ends of the belt free of the block. Pull the belt free of the motor drive assembly and the
base section and set the belt aside.
6.
Turn the pass-through mechanism over and support it so that neither the motor nor the
flange at the bottom of the base assembly is touching the work surface.
7.
Referring to Figure 3-1 and Figure 3-4, remove the eight screws holding a pair of tie
bars in place. Separate the pass-through mechanism at that joint.
8.
You may now add sections as needed and install a new belt as described in the sections
entitled Assembling the Pass-Through Mechanism and Installing the Belt.
Mechanical Installation of the Expansion and
Base Modules
The Expansion Unit and Base Module(s) may be rackmounted in either a
Compaq rack, a standard 19” EIA/RETMA rack (with a depth of 24-30”) or a
StorageWorks (SW500, SW600, or SW800) metric rack using metric
conversion brackets. Both rack types require two initial steps:
1. Separating the rack-slides.
2. Attaching the mounting-brackets.
This section describes these common rackmount instructions, followed by
rack-specific rackmount instructions. The cabling and configuration
procedures for all rackmounted MiniLibraries are described in the section
entitled Interfaces and Cabling.
Follow the directions in the shipping container to unpack the module(s). Save
the packing materials for re-use in case you need to return the module(s) for
repairs.
The Expansion Unit and the MiniLibrary Base Module comes with a slide rack
set installed on either side. The slide is attached to the Base Module enclosure
by means of three screws through the inner slide. Remove the packing tape
from the slides, and separate each set of slides as follows:

3. Identify and orient the parts of the slides and hardware needed for your
specific rack type. Figure 3-11 shows the parts required for Standard
EIA/RETMA rackmounting and Figure 3-12 shows the parts for
rackmounting into a StorageWorks metric rack.
NOTES: All of the screws, washers, nutplates and/or metric conversion brackets required
for rackmounting in either cabinet type are supplied with the Expansion Unit and Base
Module. You will need a #2 Phillips screwdriver and a flathead screwdriver.
The left and right slides are alike, so there is no risk of confusing the parts on reassembly.
The front of the cabinet, and front rails in this text refers to where the module face will be
exposed (typically opposite from the main power source location). The main power source
location thus becomes the rear of the cabinet, and where the rear rails exist.
4. Loosely assemble a mounting bracket to each outer slide, using two 1032 screws with washers and a nutplate for each. Select slots in the
mounting brackets so the length of the assembly equals the distance
between the front and rear rails of the rack.
5. Locate the screw holes in the front and rear rails of the cabinet or
equipment rack where the drive is to be installed.
CAUTION: The cooling fan at the rear of the drive must not be obstructed when
the drive is installed in the rack. It is advisable to allow two inches of clearance
behind the rear panel of the module.
6. From this point, the instructions vary depending on cabinet type, and
you should proceed as follows:
■
Refer to the Compaq Rackmounting Template, which is included with
each module.
■
EIA/RETMA Cabinet Rackmounting - Refer to the section entitled
Rackmounting in a Standard (19”) EIA/RETMA Cabinet
■
StorageWorks Metric Rackmounting - Refer to the section entitled

Metric Rackmount Procedure:
1. Refer to Figure 3-13, Metric Rackmount Installation Layout. Mount the
appropriate metric conversion bracket to both ends of the slide using the
10-32 nuts provided in the slide kit. Do this for both the left and right
slide assembly. For modules 1 and 2, use P/N 968313-101. For modules
3 and 4, use P/N 968320-101; for modules 5 and 6, use P/N 968609-101
Make sure that these brackets are oriented so that the numbers are right
side up in all corners.
2. Mounting the bracket/slide assembly to the StorageWorks cabinet:
If installing the first module, select a mounting

a. Mount each slide/bracket assembly to the rack by aligning the two
mounting holes marked #1 to holes on the rack. Start by mounting
the slide/bracket assembly to the rear of the StorageWorks first.
Hold the bracket/slide assembly in place with one hand, fasten a
mounting screw to the holes marked #1.
b. To mount the front bracket, place bracket (P/N 968312-101) in front
of the rack with the holes marked #1 aligned to the holes on the rack.
c. Extend the slide/bracket assembly forward to mate with the rack.
Align the holes marked #1 on the slide/bracket assembly with the
hole #1 on the front bracket and fasten two mounting screws through
the two #1 holes.
d. Be careful to mount all four brackets at the same height. You can use
a ruler or count holes to achieve this.
e. Tighten all four corners and the slide extension.
Procedure for installing modules 2, 3, or 4:
a. Each unit is 7 inches high. To locate the mounting location of the
next bracket/slide assembly, use a ruler to measure 7 inches vertical
distance of the protruding stud from the bracket above to the stud of
the bracket which is to be installed. The mounting holes marked for
the number of the module being installed should automatically line
up with the rack holes.

IMPORTANT: See Appendix G, Information on Pass-Through Section Covers.
Installing the Pass-Through Mechanism in the
Rack
1. If you have not previously done so, install the angle brackets on the rack
slide extensions of the top and bottom modules, using one 10-32 screw
and an L-shaped nut plate for each angle bracket. The L-shaped nut
plates should hang from the top of the slide extensions on the outside.
Place the angle brackets so the front edge of the vertical part is 15/16”
behind the rear edge of the slide body, as shown in the inset in Figure 314.
2. Referring to Figure 3-14, position the pass-through mechanism against
the back of the installed modules so that the support braces rest on the
previously installed angle brackets. Install an M4 x 20 mm screw and
washer through the rear hole in each angle bracket into the support
braces. Do not tighten.
3. Look closely at the right flange of the pass-through mechanism (left side
as viewed from the rear of the rack) as shown in the inset in Figure 3-14.
At the top module, position the pass-through mechanism horizontally so
that the edge of the flange fits exactly into the slot on the rear of the
chassis of the top and bottom modules.

4. Ensure that the bottom edge of the pass-through mechanism motor drive
section is flush with the bottom surface of the module chassis. If
necessary, adjust the vertical position of the angle brackets.
5. Repeat steps 3 and 4 at the bottom module. Tighten all of the screws that
hold the pass-through mechanism to the angle brackets while ensuring
that:
6. The pass-through mechanism is centered horizontally, as indicated by
the flange engaging the slot on the top and bottom modules, and
7. It is centered vertically, as indicated by the bottom of the bottom of the
pass-through mechanism being flush with the bottom of the lowest
module, and
8. The pass-through mechanism is pressed firmly against the backs of the
top and bottom modules.
9. One by one, push the remaining modules into place and tighten the
captive screws. In each case, ensure that the module does not bind
against an adjacent module, that clearance between modules is evenly
divided between top and bottom, and that the flange on the pass-through
mechanism engages the slot on the back of the module.
10. If binding occurs, or if the module is not centered on the pass-through
mechanism, loosen the four screws that secure the slides of the binding
module to the front rails and the four screws that secure the slides to the
rear rails, reposition the slides, then retighten the screws.
11. If necessary, repeat steps 6 and 7 until the module does not bind against
the slides or against adjacent modules.
12. Repeat steps 6, 7, and 8 for all of the remaining modules.
Interfaces and Cabling
Refer to Figure 3-15. The connections required depend on the type of module.
The Expansion Unit always has the SCSI connection to the host for the library
robotics. Base modules have a separate SCSI connection to the host for each
drive*, but the SCSI connectors for the robotics should not be used. The
portion of the library robotics that is located in the Base Modules is controlled
by the Expansion Unit through a cable connected to the Expansion Interface
connector on each module. Each module has a separate AC power connection.
*IMPORTANT: In principle it is possible to daisy-chain the SCSI connections for multiple
drives, to save SCSI controllers. Compaq strongly recommends against this practice
because it may severely limit the data throughput performance and reliability of the
library.

Power Cord
The detachable AC power cord is a standard grounding AC cord which
attaches to an IEC-compatible connector on the rear panel. Connect a cord to
the connector on each module, and connect the other end to a reliably
grounded AC outlet or rack power outlet.
To maintain safety compliance, use a power cord with a suitable rating that is
approved for the country in which the product is used. In the USA, cords must
be UL listed, in Canada, CSA certified, and in Europe use a Harmonized cord
marked <HAR> or a nationally certified cord. Compaq specified power cords
are available as part of the associated TL891 Country Kits (Ordered
separately.)
SCSI Interfaces
MiniLibrary Modules come with a differential Fast/Wide SCSI and one or two
TZ89 drive(s). Fast/Wide SCSI is available as differential, and uses two
parallel female high-density 68-pin D-Series connectors per bus. Fast/Wide
SCSI cables and terminators are secured to the connectors by jackscrews.
NOTE: Compaq strongly recommends that you use differential controllers and highquality SCSI cables to ensure the highest performance of your MiniLibrary. Bus errors
caused by excessive length or poor quality cables can significantly degrade performance
and reliability.
In the Base Module, each drive is wired to an independent bus with a pair of
SCSI connectors. Because it can be used in free-standing applications, the
Base Module has a pair of SCSI connectors for that module’s library robotics.
The library robotics SCSI interface should not be connected when installed in
a system with an Expansion Unit. The Expansion Unit controls the library
robotics for all of the modules in the system. It has a single SCSI bus, with a
pair of SCSI connectors, to enable a host to control the library robotics.
Each of the drives in the system and the library robotics is a separate SCSI
device and is wired to a separate SCSI bus. Any of the separate buses may be
combined using a SCSI jumper cable, available from Compaq. If any two or
more devices are connected to the same SCSI bus, each must be assigned a
unique SCSI address. For information on assigning SCSI addresses, see the
section entitled Configuration.

Installation 3-31
NOTE: For best performance, no more than two TZ89 drives should be connected to a
single SCSI bus, because of the bandwidth limitations of the SCSI bus.
A terminator of the proper type (68-pin differential) must be installed on each
unused connector at the end of each bus, as explained below in the section
entitled Interface Cable and Terminator Installation. Figure 3-15 shows the
SCSI cable, connectors and bus terminator used on the module.
In order to connect a module to a host computer system, the host system must
have at least one SCSI controller and the appropriate driver software. As noted
earlier, higher-speed drives may require the use of separate SCSI controllers
for each drive or each pair of drives. No more than two TZ89 drives should be
connected to a single SCSI bus. Your Technical Support representative is
available to answer your questions about installation procedures for specific
host systems. Before cabling the system, see the recommended SCSI cable
specifications in the following section. Also, see the section entitled Interface
Cable and Terminator Installation.
Interface Cable Specifications
The MiniLibrary is a high-performance system. To avoid degradation of
performance, use the highest-quality interface cables. The detailed
requirements for SCSI cables are set forth in ANSI X3.131-1994. All SCSI
cables used with the MiniLibrary Module meet at least the following
requirements:
■
Shielded or double-shielded, as required to meet EMI specifications;
■
Impedance match with cable terminators of 132 ohms, ideally;
■
Characteristic impedance between 90 and 132 ohms, required;
■
Each end of the twisted pair ground must be connected to chassis
ground;
■
The maximum cable length for a differential Fast SCSI bus is
82 ft. (25 m)
IMPORTANT: When calculating the overall length of the bus, be sure to include the
internal cabling of the module, which is as follows:
MiniLibrary Base Module:
Fast/Wide (TZ89 Drive)
DLT0
14 inches (36 cm)
DLT1
23 inches (57 cm)
Expansion Unit:
32 inches (81 cm)
■
Cables of different impedances should not be used together.

3-32 TL891 MiniLibrary System User's Guide
Additional specifications to assure the highest SCSI performance can be found
in ANSI X3.131-1994 or later.
NOTE: This equipment has been tested for electromagnetic emissions and immunity
using good quality shielded cables. The use of unshielded cables, poor quality cables or
other variances from good practice may result in non-compliance with national and
international rules.
Terminators
A terminator must be installed on the device if the device is to be used at either
end of a SCSI bus, such as the first or last device along a daisy-chain, or as a
single SCSI peripheral. The appropriate type and quantity of terminator is
shipped with your module. They are packaged in the accessory bag that arrives
with the module.
NOTE: It is important to use only differential terminators on a differential SCSI bus.
Interface Cable and Terminator Installation
To properly cable a module:
1. Make sure that your host system has an appropriate SCSI interface card
for each SCSI bus and software drivers installed.
2. Inspect the terminator and make sure it is a differential type. SCSI
terminators should be clearly marked ‘single-ended’ or ‘differential’.
3. Determine whether the module is to be connected in daisy-chain fashion
with other devices.
4. If not used in a daisy-chain, install the terminator in the second SCSI
connector.
5. If used in a daisy-chain, and the drive is the last device of the chain,
install the terminator in the second SCSI connector. Otherwise, do not
use the terminator. Connect the next cable in the chain to the second
SCSI connector.
6. Make sure that the cable you use meets the specifications listed earlier
in this chapter.
7. Measure the cable length to connect the module to the computer system.
8. Be sure that the length of the entire bus falls below the maximum
permissible length given in the section entitled Interface Cable
Specifications.

Configuration
Individual MiniLibrary Base Modules in all newly assembled systems must be
configured as described in the next section. In addition, the MiniLibrary
System is designed with several configuration options, each offering multiple
settings to support a variety of applications and platforms. The setting of each
option is stored in non-volatile memory in the module. For most applications,
you will not need to change the factory default settings.
To change settings, you need to use the control panel on the Expansion Unit.
For an overview of how the control panel works, and a description of the
functions of the buttons, indicators and display, refer to sections entitled
Entering the Menu Mode, Exiting the Menu Mode, and Navigating Through
the Menu Structure in Chapter 2, Operation.
The settings can be changed using the procedure described in the section
entitled A Configuration Example - Setting the SCSI ID, covered later. Before
changing any configuration settings, consult your host system documentation
to determine which settings may need to be changed.
Setting Base Module (slave) Configuration
IMPORTANT: All MiniLibrary base modules are shipped configured as standalone
systems. Before powering up the Expansion Unit in a MiniLibrary system for the first time,
you must reconfigure each of the base modules in the system as a slave. To do so,
perform the following procedure on each base module.
1. Turn on the power switch on the Base Module. After a series of self-test
screens, the screen shown in Figure 3-18 appears:

Setting up a Mail Slot
Some of the available host software enables the system administrator to limit
access to the library as a whole while permitting insertion into or removal
from the library of one or more tape cartridges when needed. This feature is
commonly called a mail slot. It is implemented using SCSI Import/Export
elements.
In the MiniLibrary system, you can designate the magazine of any Base
Module as the mail slot magazine. When you do so, the entire magazine is
withdrawn from the list of storage elements. You can designate any number of
mail slots from one slot up to the full size of the magazine. To configure a
mail slot, use the following procedure.
1. As shown in Figures 3-25 through 3-27 in the preceding procedure,
navigate from the Default Screen through the Main Menu to the
Configure Submenu.
2. Scroll down on the Configure Submenu until you see ‘Set Mail Slot’,

Descriptions of Configuration Options
Table 3-2 summarizes the configuration settings for the MiniLibrary System.
The items available on the Configuration Menu are as follows:
Set Data Format: This setting enables you to 1) set the data format to Auto
Selection, THZ01, THZ02, DLT2000, DLT2000XT, DLT4000; or DLT7000;
and 2) Auto Selection, enable, disable data compression. Compression can not
be enabled when either THZ01 or THZ02 format is in use. This setting applies
to the next or currently loaded cartridge only. An unload command returns to
the default. This setting does not display the current format of the loaded tape.
Use the Show Status Menu for this purpose. The default for density and
compression is Auto Selection.
Set SCSI: This setting enables you to 1) enable or disable the library robotics
SCSI bus parity checking, and 2) set the SCSI addresses of the drives and the
library robotics. The defaults are: parity enabled; Library Bus ID = 0. The
designators DLT 0 through DLTn refer to the first through nth drives, counting
from top to bottom. The actual designator used by the system depends on the
number of drives in the system and the placement of the module in the system.
Set Library Mode: This option enables you to set the library robotics
operating mode to Random, Sequential DLT0, Sequential DLT1, or Sequential
Split. Random is the normal operating mode which affords complete host
control of the library robotics. The Sequential modes are locally controlled
modes. Sequential DLT0 begins with any cartridge loaded into DLT0. The
Base Module monitors the status of DLT0, and when the cartridge is unloaded
by the host, it loads the next cartridge in magazine numerical order. This
operation continues to cycle until all of the cartridges have been loaded.
Sequential DLT1 is the same, except that the cartridges are loaded into DLT1.
Sequential Split mode provides two simultaneous sequential modes. Cartridges
0 through 4 are loaded sequentially into DLT0; cartridges 5 through 9 are
loaded sequentially into DLT1.
Set Element Base: This setting allows you to set the base addresses of each of
the four SCSI elements of the module. In order to identify sources and
destinations in commands to the robotics, the Library System is divided into
elements, each of which is assigned a separate designator or element address.
The Transport Element is the robotics mechanism itself; the Storage Elements
are the slots in the magazines; the Transfer Elements are the drives, and the
Import/Export Element is the mail slot or slots. The Module reports these
settings in response to the SCSI Mode Sense command, in the Element
Address Assignment Page. The defaults are Transport element base = 0000,
Storage element base = 0001, Transfer element base = 00F0, and
Import/Export element base = 00E0.

Set Identification: This setting enables you to specify the response of the
Module’s robotics to the SCSI Inquiry command in the Vendor ID and the
Product ID fields. The defaults are: Vendor ID = DEC; Product ID TL800.
Set Date: Enables you to set the system’s calendar.
Set Time: Enables you to set the system’s clock.
Set Baud Rate: Enables you to set the data transmission rate of the Expansion
Unit’s trace port. This function is intended for use by Customer Engineers
only. The default is 38400 bits/sec.
Set Serial number: This setting enables you to alter the Expansion Unit’s
serial number as stored in the unit. The Module’s robotics reports these
settings in response to the SCSI Inquiry command, in the Unit Serial Number
Page.
Set Unload Mode: This setting determines whether a SCSI Move Medium
command is interpreted as implicit or explicit. If implicit, the Expansion
unloads a drive before attempting to move a cartridge from that drive. If
explicit, the host must issue a SCSI Unload command to the drive before each
Move Medium command from a drive to a slot. The default is Implicit.
Set Auto Clean Mode: This function, when enabled, will sense the tape
drive’s cleaning request and after the next unload, load a Cleaning Cartridge
into the drive. After cleaning is complete, the cartridge is returned to slot. The
default is disabled.
NOTE: This function is application dependent.
Set Negotiation Mode: This option offers two choices: Initiate Negotiation
and Set Transfer Rate. Initiate Negotiation, if set, allows the system to initiate
SCSI Synchronous Negotiation with the host (the default is No). The
Expansion always responds to host-initiated negotiation. Set Transfer Rate can
be set to 10 Mbytes/sec, 5 Mbytes/sec or Asynchronous. The default is 10
Mbytes/sec.
Set Mail Slot: Some of the available host software enables the system
administrator to limit access to the library as a whole while permitting
insertion into or removal from the library of one or more tape cartridges when
needed. This feature is commonly called a mail slot. It is implemented using
SCSI Import/Export elements.

Configuration
This chapter describes how to customize configuration of the MiniLibrary
Base Module and defines configuration options.
The MiniLibrary Base Module is designed with several configuration options,
each offering multiple settings to support a variety of applications and
platforms. The setting of each option is stored in non-volatile memory in the
module. For most applications, you will not need to change the factory default
settings. If you need to change the configuration, go on to the next section. If
you are uncertain whether you need to change a setting, contact your
Technical Support representative.
To change settings, you need to use the Control Panel. For an overview of how
the Control Panel works, and a description of the functions of the buttons,
indicators and display, refer to the sections entitled Entering the Menu Mode,
Exiting the Menu Mode, and Navigating Through the Menu Structure, in
Chapter 2, Operation.
The settings can be changed using the procedure described below under How
to Customize Configuration. Before changing any configuration settings,
consult your host system documentation to determine which settings may need
to be changed.
How to Customize Configuration
Turn the module on, and wait until the Power-On Self Test terminates and the
default screen appears on the display. Figure 4-1 shows a typical Default
Screen. Yours may vary depending on the number of drives in your library

Set Data Format
This setting enables you to 1) set the data format to Auto Selection, THZ01,
THZ02, DLT2000, DLT2000XT, DLT4000; or DLT7000; and 2) Auto
Selection, enable, disable data compression. Compression can not be enabled
when either THZ01 or THZ02 format is in use. This setting applies to the next
or currently loaded cartridge only. An unload command returns to the default.
This setting does not display the current format of the loaded tape. Use the
Show Status Menu for this purpose. The default for density and compression is
Auto Selection.
Set SCSI
This option enables you to 1) enable or disable the library robotics SCSI bus
parity checking, and 2) set the SCSI addresses of the drives and the library
robotics. The defaults are: parity on, DLT 0 address = 4, DLT 1 address = 5,
robotics address = 0.
Set Library Mode
This option enables you to set the library robotics operating mode to Random,
Sequential DLT0, Sequential DLT1, or Sequential Split. Random is the normal
operating mode which affords complete host control of the library robotics.
The Sequential modes are locally controlled modes. Sequential DLT0 begins
with any cartridge loaded into DLT0. The Base Module monitors the status of
DLT0, and when the cartridge is unloaded by the host, it loads the next
cartridge in magazine numerical order. This operation continues to cycle until
all of the cartridges have been loaded. Sequential DLT1 is the same, except
that the cartridges are loaded into DLT1. Sequential Split mode provides two
simultaneous sequential modes. Cartridges 0 through 4 are loaded sequentially
into DLT0; cartridges 5 through 9 are loaded sequentially into DLT1.

Set Element Base
This option allows you to set the base addresses of each of the three SCSI
elements of the module. In order to identify sources and destinations in
commands to the robotics, the base module is divided into elements, each of
which is assigned a separate designator or element address. The Transport
Element is the robotics mechanism itself; the Storage Elements are the 10 slots
in the magazine; the Transfer Elements are the drives. The Base Module
reports these settings in response to the SCSI Mode Sense command, in the
Element Address Assignment Page. The defaults are Transport = 0000h,
Storage element base = 0001h, Transfer element base = 00F0h.
Set Date

Configuration 4-15
Set Time
Enables you to set the module’s clock.
Set Baud Rate
Enables you to set the data transmission rate of the module’s trace port. This
function is intended for use by Customer Engineers only. The default is 38400
bits/sec.
Set Serial Number
This option enables you to alter the Base Module’s serial number as stored in
the unit. The Base Module’s robotics reports these settings in response to the
SCSI Inquiry command, in the Unit Serial Number Page.
Set Unload Mode
This option determines whether a SCSI Move Medium command is interpreted
as implicit or explicit. If implicit, when the module receives a SCSI Move
Medium command for a fetch from a drive, it unloads the drive before
attempting to fetch a cartridge from that drive. If explicit, the host must issue a
SCSI Unload command before each Move Medium command where the
source element is a drive. The default is Implicit.
Set Auto Clean Mode
This function, when enabled, will sense the tape drive’s cleaning request and
after the next unload, load a Cleaning Cartridge into the drive. After cleaning
is complete, the cartridge is returned to slot. The default is disabled.
NOTE: This function is application dependent.
Set Negotiation
This option allows the Base Module to initiate negotiations for synchronous
data transfer and wide data transfer from the host. Only models with a
fast/wide drive installed can initiate a ‘wide’ negotiation. The default is Do
Not Initiate.
Set Mail Slot
Some of the available host software enables the system administrator to limit
access to the library as a whole while permitting insertion into or removal
from the library of one or more tape cartridges when needed. This feature is
commonly called a mail slot. It is implemented using SCSI Import/Export
elements.

Diagnostics and Troubleshooting
This chapter describes the procedures for diagnosing platform problems and
drive errors that can cause the MiniLibrary to malfunction. It also provides
Fault Symptom Codes and Error Recovery Procedures to help restore
operability.
Diagnosing Problems
There are two main types of problems that can cause the DLT MiniLibrary to
malfunction or fail to perform correctly: platform problems and general drive
errors. Some errors cause Fault Symptom Codes (FSC) to be displayed on the
control panel, along with a description of the fault. Error Recovery Procedures
(ERP) are available for each FSC. They are described in this chapter.
Platform Problems
These errors arise out of incorrect installation and configuration. The most
common characteristic of this type of error is that the drive appears to operate
normally, except that no data can be interchanged. You may not get an error
code on the control panel. To identify an error as this type of problem, check
your installation and configuration setup, referring back to Chapter 3,
Installation and Chapter 4, Configuration.
General Drive Errors
These errors usually result from a miscommunication between the drive
processors or involve a mechanical malfunction. In most cases, these types of
errors report an error message and an FSC to the control panel. The only

exceptions are power supply problems and display malfunctions. The FSC can
be used to determine a recovery procedure.
Some error messages can be cleared by pressing the Enter button on the
control panel, others by cycling the power to the library. Often the module will
resume normal operation. Other errors are repeated when the operation is
attempted again. Such recurrent errors may require more extensive recovery
procedures, such as replacement of a part.
To aid you in localizing persistent errors, there are Customer Engineer
diagnostics available in the Maintenance Submenu and a user diagnostic
available on the Demo Submenu. The diagnostics are described at the end of
this chapter.

Of these selections, only Cartridge Cycle is intended for use in the field. The
remaining tests are used during factory setup.
Cartridge Cycle Diagnostic
When you select Cartridge Cycle, the library robotics begin to move cartridges
randomly from slot to slot in the magazine, while reporting on the front panel
the number of passes.
This diagnostic will run continuously as long as the Base Module has power.
To stop the test, press the Escape button. A flashing message appears on the
display telling you that the test is paused. Pressing the Escape button a second
time terminates the diagnostic and returns to the Maintenance Menu.
Using the Demo Submenu
The only User Diagnostic is found on the Demo submenu on the Maintenance
Menu. The submenu lists five demos, numbered 1 through 5. At present, only
Demo 1 is implemented. Demo 1 enables the user to fully exercise the library
robotics.
When you select Demo 1, the library robotics begins to move cartridges
randomly from slot to slot in the magazine, while reporting on the front panel
the number of passes. If all ten slots in the magazine are full, Demo 1 will load
a cartridge into DLT0 and leave it there. If you press the button while
Demo 1 is running, the system will load a cartridge into DLT0, unless DLT0 is
full. If you press the button again, the cartridge is unloaded from DLT0 and
returned to the magazine. The button causes DLT1 to be loaded and
unloaded in the same way.
Demo 1 will run continuously as long as the Base Module has power. To stop
the test, press the Escape button. A flashing message appears on the display
telling you that the test is paused. Pressing the Escape button a second time
terminates Demo 1 and returns to the Maintenance Menu.

Product Notes for Windows NT and
Novell NetWare
This appendix provides information for the system administrator who should
read this appendix before installing and using the Model TZ89 DLT
Cartridge Tape Drive with a host system operating under the Windows NT or
Novell NetWare operating systems.
Host SCSI Interface
Compaq Corporation has tested and supports the TZ89 DLT Cartridge Tape
Drive under the Windows NT and Novell NetWare operating systems.
The TZ89 DLT Cartridge Tape Drive uses the standard SCSI-2 command set
to interface to a PC-based host system. The host system must be equipped
with a SCSI adapter to properly interface the tape drive with the host. For
example, the host SCSI adapter might interface the computer’s PCI bus to the
SCSI-2 port of the tape drive. A host PC SCSI adapter is normally supplied
with compatible software drivers for use with several operating systems. The
software driver(s) must be pre-loaded in accordance with the SCSI adapter
manufacturer’s installation procedure.
In addition, there are many commercial software products available that
provide host or network-based functionality (data backup and restore,
archiving, data logging, etc.) for these operating systems. Before selecting a
user-level software product, ensure that the TZ89 DLT Cartridge Tape Drive
is supported by that product. Commercial software vendors usually publish a

Product Notes for Sun
This appendix describes how to include the Model TZ89 DLT Cartridge
StorageWorks Building Block (SBB) Tape Drive in a Sun SPARC system
running Solaris 2.4 (or later). The information covers the installation of the
Model TZ89 DLT Cartridge Tape Drive hardware and configuring the system
to communicate with the drive.
General Information
■
Densities can only be changed at the beginning of the tape.
■
Front panel operation will override software control of density and
compression settings.
■
To use software-controlled density selections, the drive must first be
placed in “automatic” mode. To accomplish this, press the DENSITY
SELECT button the required number of times until only the DENSITY
OVERRIDE light is blinking.
■
Compression can be enabled or disabled at any time, with the change
taking effect immediately when writing TZ89 density.

Installation Procedure
NOTE: In order to support the addition of this device, drive information must be supplied
in the /kernel/drv/st.conf file as global properties that apply to each of the targets, or as
properties that are applicable to one target only. The "st driver" looks for the property
called "tape-config-list". For additional information, read the man page “st”. We recommend here the use of the global properties approach.
System Modification
Perform the following steps to modify the system to communicate with the
tape drive:
1. From the command line, type:
cd /kernel/drv
2. Edit the “st.conf” file by adding the following before the first
occurrence of “name=":
# entry for TZ89 tape drive
tape-config-list = "DEC
TZ89",
"DEC 70GB Cart. DLT Streaming /w Compression”,
“TZ89-data”;
TZ89-data = 1,0x36,0,0x1639,4,0x82,0x83,0x84,0x85,3;
Where:
In the “tape-config-list” parameter:
■
The first parameter (DEC
TZ89) is the parameter returned by the
TZ89 DLT Cartridge SBB Tape Drive on a SCSI inquiry command.
(There should be five spaces between “DEC” and “TZ89” elements.)
■
The second parameter (DEC 70GB Cart. DLT Streaming /w
compression) is a nickname for the drive.
■
The third parameter is defined as follows:
–
–
In the “TZ89-data” string:
The first parameter (1) is the revision level of the software and is set
to 1.
The second parameter (0x36) is the tape type, specifying “other”
tape drive. (This is defined in /usr/include/sys/mtio.h.)

The third parameter (0) is the block size in bytes. Zero “0” means
variable block size.
The fourth parameter (0x1639) defines the options selected. The
0x1639 value represents the following
options:
ST_VARIABLE
= 0x0001
ST_BSF
= 0x0008
ST_BSR
= 0x0010
ST_LONG_ERASE
= 0x0020
ST_KNOWS_EOD
= 0x0200
ST_UNLOADABLE
= 0x0400
ST_LONG TIMEOUTS = 0x1000
–
The fifth parameter (4) defines the number of densities. The
maximum definable number of densities is 4, which is a Sun
Operating System limitation.
NOTE: In our example entry we choose to use TZ88 native and compressed modes for
the two lower densities and TZ89 native and compressed modes for the two higher
density drivers. Because your situation may demand something other than these
settings, we have included Table D–1 which lists all other valid density values. Refer to
Table D–1 for other density settings.

The sixth parameter (0x82) is the vendor-unique density code for the
CT-IV, 20 GB.
The seventh parameter (0x83) is the vendor-unique density code for
CT-IV, 40 GB compressed mode.
The eighth parameter (0x84) is the vendor-unique density code for
the CT-IV, 35 GB.
The ninth parameter (0x85) is the vendor-unique density code for the
CT-IV, 70 GB compressed mode.
The last parameter in the TZ89-data parameter is the default density

Where:
CT-IV = CompacTape IV Data Cartridge
System Shutdown
After you have edited the “st.conf” file, shut down the system as follows:
sync
cd /
shutdown -i0 -g0 -y
Installation of the Tape Drive
Install the tape drive into the storage subsystem and power on the workstation.
We recommend that the TZ89 DLT Cartridge Tape Drive SCSI device address
be set to ID 4 or 5.
NOTE: If your SCSI host adapter is supported by the “probe-scsi” command, then
you can use this command at the boot prompt to verify that the connected device is
correctly attached to the system.

Rebooting of System
Reboot the system using the following command at the boot prompt:
>boot -rv
NOTE: The switch "r" forces the kernel to be re-configured, and switch "v" enables a
display of the system configuration at boot time
The system compiles the kernel and creates special files in /dev so that it can
communicate with the TZ 89 DLT Cartridge SBB Tape Drive. Since you
booted the system using the verbose switch, the system displays all of its SCSI
targets. Verify that “DEC 70GB Cart. DLT Streaming /w
Compression” is displayed as a target when the system is booting.
At this time, the tape drive is configured in the /dev directory in two ways:
rmt format, and rst format.
“rmt” format
In this format, the drive is configured with various options. For further
explanations, see the man pages on “st” (the modes are x, xl, xm, xh, xc, and
xu, where x is the rmt number).
■
Options x, xu, and xc, correspond to the 0x85 (CT-IV, compressed)
density mode.
■
Option xl, corresponds to the 0x82 (CT-IV) density mode.
■
Option xm corresponds to 0x83 (CT-IV) density mode.
■
Option xh corresponds to 0x84 (CT-IV, native) density mode.
■
Option b associates with the BSD behavior and is for backward
compatibility on all of the above options. For further information, refer
to the man pages of “mtio”.
■
The n option provides access to the device with no rewind, similar to
nrst (below), and is also applicable to all of the above options.
Where:
CT-IV = CompacTape IV Data Cartridge

Product Notes for Sun D-7
“rst” format
Special files “rst” (rewind on close) and “nrst” (no rewind on close) are also
built and reside in the /dev directory. For example, if the SCSI target ID for
the drive is 4 and the drive is connected to the native SCSI bus, then “rst” will
be “rst4, rst12, rst20, and rst28” and nrst will be “nrst4, nrst12, nrst20, and
nrst28”.
■
rst4 and nrst4 correspond to the 0x82 density mode (CT-IV, native
format)
■
rst12 and nrst12 correspond to the 0x83 density mode (CT-IV,
compressed format)
■
rst20 and nrst20 correspond to the 0x84 density mode (CT-IV, native
format)
■
rst28 and nrst28 correspond to the 0x85 density mode (CT-IV,
compressed format)
Where:
CT-IV = CompacTape IV Data Cartridge
Test
To test the TZ89 DLT Cartridge Tape Drive, back up the “passwd” file to
tape using the “tar” command, as follows:
tar
cvf
/dev/rst4
/etc/passwd
The system responds with:
a
/etc/passwd
1 blocks
NOTE: depending on the size of the file, a different number of blocks may be reported.
Verification
Verify that the “passwd” file was saved to tape using the following command:
tar
tvf /dev/rst4
The system responds with
/etc/passwd

Information on Pass-Through Section
Covers
This appendix supplements the information presented in the section entitled
Mechanical Installation in Chapter 3.
IMPORTANT: These procedures should be performed by a qualified service technician.
Pass-Through Section Covers
The Pass-Through mechanism moves tape cartridges vertically between
TL891 MiniLibrary modules. Each module section is covered by an individual
sheet-metal enclosure. These covers protect the mechanism during shipping
and are an important safety shield during operation.
A separate detachable side plate is part of the cover assembly. During
installation the side plates should be removed on any mechanism sections
located behind a MiniLibrary module; this allows easy access to a cartridge
stranded in transit by a commercial power outage. The remaining portion of
the cover can be removed also from any section behind a module.
IMPORTANT: Both parts of the covers must remain in place over any section of the
mechanism that is not behind a MiniLibrary module. Any gaps between modules should
remain completely covered.
Figure G-1 shows the cover assembly side plate (1) and Figure G-2 shows the
mechanism section cover (2).

Care and Handling of Cartridges
CompacTape is a digital linear tape (DLT) that has been designed and
formulated for use in DLT tape drives and tape libraries. The high-grade metal
particle tape features demonstrated tape durability and a long archival life.
As with any data storage medium DLT tape cartridges require some care in
handling and storage. The Following guidelines will help protect your valuable
data.

Handling and Storage Guidelines
■
Do not carry cartridges loosely in a box or other container that exposes
them to unnecessary physical shock.
■
Store each cartridge in its protective case until you select it for use in a
tape drive or library.
■
Do not drop or bump the cartridge. This may dislodge and/or damage
internal components.
■
Avoid unnecessary opening of the cartridge door; this may expose the
tape to contamination or physical damage.
■
Do not allow direct contact with tape or the tape loader. Even dust or
natural skin oils can contaminate the tape and impact tape performance.
■
Do not expose the tape cartridge to moisture or direct sunlight.
■
Maintain a clean operating, working, and storage environment.
■
Do no place cartridges on or near devices that may produce a magnetic
field, such as computer terminals, motors, and video or x-ray equipment.
Such exposure can alter or erase data on the tape.
■
Do not attempt to remove a cartridge from the drive unless the drive
indicator (the green LED) is illuminated. Overiding the drive handle will
cause damage to both the media cartridge and the drive.
■
The ambient operating environment for the tape cartridge is:
‰
‰
Temperature: 10°C to 40°C (50°F to 104°F)
Relative Humidity: 20% to 80% (non-condensing)
If Storage and/or transportation of a tape cartridge has exposed it to conditions
outside the ambient values above, allow the cartridge to remain unused in its
operating environment for 24 hours before using it.

Checking a Cartridge for Damage
If a cartridge has been dropped or if you have other reason to believe it may be
damaged, inspect it carefully before inserting it into the library. Inspect the
cartridge as follows:
1. Shake the cartridge and listen for any sound of a broken part (such as a
reel lock). Any rattling noise is an indication that the cartridge has been
damaged and must not be used.
2. Look at the plastic case carefully for any sign of distortion, bending or
cracks.
3. Open the spring-loaded cartridge door by releasing the slide lever (1) at
the door hinge until you see the cartridge (takeup) leader (2).

4. See if the cartridge (takeup) leader appears in its normal position
(protrudes about a 5-degree angle from the case.) If necessary, compare
it to a cartridge that has not been dropped.
CAUTION: If the leader is out of position, do NOT use the cartridge; it can cause
the drive takeup leader to fail.

5. Verify that the two reel lock levers are in position: one is located on the
same surface as the cartridge leader door, the other is located on the
bottom of the cartridge near the front left-hand corner. Both reel locks
should be visible and in the same position as a cartridge that has not
been dropped.
6. Verify that the hub reel is flush with the case surface. If the hub reel is
compressed it could become misaligned

Archival Guidelines
Ensure the reliability of archived cartridges that contain recorded data by
storing them in a clean, controlled environment with the following conditions:
Temperature 18°C to 28°C (64°F to 82°F)
Relative Humidity: 40% to 60% non-condensing
The above environment also ensures maximum shelf life of cartridges that do
not yet contain data.
Unrecorded (blank) cartridges can be stored under the following conditions:
Temperature 16°C to 32°C (61°F to 89°F)
Relative Humidity: 20% to 80% non-condensing
Transportation Guidelines
Keep within the following environmental guidelines when shipping cartridges:
Unrecorded (Blank) Cartridges

Tape Drives and Cartridges H-7
Also follow these guidelines:
■
Avoid mechanical stress that may distort the shape of cartridge, such as
dropping or bumping the cartridge.
■
Fit cartridges into a rigid container with adequate shock-absorbing
material. The container should have a clean interior and construction
that provides sealing to prevent invasion by dirt and/or water.
■
Mark the shipping container to clearly identify its correct orientation.
■
Avoid exposing cartridges to widely varying temperatures and/or
humidity whenever possible
■
Condition newly-received cartridges in their operating environment for
at least 24 hours before use.
■
Minimize potential damage from stray magnetic fields by ensuring a
nominal spacing of not less than 80 mm (3.2 inches) between the
cartridge and the outer surface of its shipping container.
Cleaning Guidelines
See the following guidelines and refer to H-1 for instructions on using the
cleaning cartridge to clean the tape drive heads.
■
Under normal conditions, the cleaning cartridge is effective for about 20
cleanings. If the cleaning cartridge has been overused, the Use Cleaning
Tape will remain lit after you load the cleaning cartridge and no
cleaning action will take place. When this happens, use another cleaning
tape.
■
DLT tapes do no usually need regular cleaning, as their design allows
for minimal head contamination. The action of loading and using any
tape tends to clean the heads of the tape drive.
■
Use the cleaning tape no more than once every 2 weeks (or after 50
hours of continuous tape use).
■
When the Use Cleaning Tape (LED) lights, take note the tape in use at
the time. This tape may be causing head contamination. Try another tape
before using the cleaning tape, to see whether the Use Cleaning Tape
LED stays on.
■
Use the cleaning tape more than once if a tape has severely
contaminated the drive heads. If the problem persists after two
cleanings, contact Compaq for service.

Tape Drives and Cartridges H-9
Cleaning the Tape Drive Heads
The tape drive heads physically read and write data to and from the tape
cartridge. Under normal conditions, the heads require cleaning only when the
"Use Cleaning Tape" LED indicates that it is required.
IMPORTANT: Never attempt to clean the heads in a manner other than described in the
following procedure. Doing so can void the product warranty.
To clean the heads:
1. Apply power to the tape drive and wait for the green Operate Handle
indicator to light.
2. Raise the cartridge insert/release handle and insert the cleaning cartridge
into the drive, then lower the handle.
3. The drive automatically executes the head-cleaning operation, which
takes at least 30 seconds. When the cleaning cartridge has completed
this task, the green Operate Handle indicator lights.
4. Remove the cleaning cartridge.
5. Mark the frequency-of-use label on the cleaning cartridge, placing a
check mark in the next available square on the card each time you use
the cleaning cartridge.
CAUTION: Remove the cleaning cartridge as soon as possible following
completion of the cleaning operation. Leaving a cleaning cartridge in the
drive can result in redundant cleaning operations each time power to the
tape drive is turned off and on, resulting in unnecessary wear on the tape
drive's read/write heads.

Preparing Cartridges for Use
The TL891 MiniLibrary comes with one DLT tape cartridge and one cleaning
cartridge.
IMPORTANT: The TL891 MiniLibrary accepts only CompacTape III, CompacTape IIIXT,
and CompacTape IV cartridges. For best performance, use CompacTape IV cartridges in
the library. DO NOT use CompacTape I or CompacTape II cartridges.
NOTE: To order additional tape cartridges, contact you Compaq authorized dealer or
resealler.
Applying Bar Code Labels
Before placing a cartridge in the library, you must apply a bar code label that
uniquely identifies it to the library. When applying the bar code label:
■
Use only the labels provided with the library.
■
Apply cleaning cartridge labels only to cleaning cartridges; apply data
labels only to data cartridges.
■
Apply the label (1) to the front face of the cartridge as shown in the
following figure.
