The LTO tape drives communicate with the library through an internal Ethernet interface. For enhanced performance, the LTO tape drives include speed matching, channel calibration, and power management.

Speed matching dynamically adjusts the drive’s normal native (uncompressed) data rate to the slower data rate of a server. Channel calibration customizes each read/write data channel for optimum performance. The customization enables compensation for variations in the recording channel transfer function, media characteristics, and read/write head characteristics. Power management reduces the drive’s power consumption during idle power periods.

Control path drives

A control path is a logical path to the library. A control path is the path for

SCSI Medium Changer

commands sent by a server to control a specific logical library. The library has no direct SCSI connection to a host server. When a software host server communicates with the library, it sends the communication by way of a tape drive. The tape drive is designated as a control path drive.

Mixed drives

All supported generations of LTO tape drives and cartridges can be in the same physical library and within a single module.

12

Dell EMC ML3 Tape Library: User's Guide

This library supports a mixture of LTO drive types in a logical library. Some independent software vendors (ISVs) support mixed drive types within a logical library and other do not. Some ISVs that support mixed drive types might have restrictions. For details, contact your ISV.

Figure 17 shows examples of methods for mixing LTO drive types in a logical library.

Physical and logical addresses of drives

The library assigns each tape drive a unique address to indicate its physical location, shown in Figure 22 on page 16. The physical numbering is bottom up on all drives. This information is shown on the Drives

page of the Management GUI.

Overview

15

Figure 22. Physical numbering of drives

The library assigns each tape drive a SCSI element address that consists of a value that defines a logical location in the library to the SCSI interface. It is assigned and used by the application when the host server processes SCSI commands. The SCSI element address for a drive is unique to the location of the

drive. It does not vary based on other drives in the library. See “Library partitioning” on page 57.

Supported tape cartridges

Within the library, the supported LTO tape drives use the following cartridge types: v LTO8 Data Cartridge v LTO8 WORM Data Cartridge v LTO7 Data Cartridge v LTO7 WORM Data Cartridge v LTO6 Data Cartridge v LTO6 WORM Data Cartridge v

LTO5 Data Cartridge v LTO5 WORM Data Cartridge v LTO4 Data Cartridge v LTO4 WORM Data Cartridge v Universal LTO Cleaning Cartridge

Library functions

Encryption

All supported tape drives in this library support encryption.

The encryption enabled drive contains the necessary hardware and firmware to encrypt and decrypt host tape application data. Encryption policy and encryption keys are provided by the host application or host server. A drive digital certificate is installed at manufacturing time. Each drive receives a unique serial number and certificate. The T10 application might validate each drive instance by checking the drive's digital certificate.

The library provides these options.

1.

Encryption disabled

2.

Application Managed Encryption

(AME)

3.

Library Managed Encryption (KMIP)

(LME). LME is a built-in feature. For configuration details, see

“Configuring Library Managed Encryption (KMIP)” on page 70.

The default is Application Managed Encryption.

Enabling library-managed encryption on a Dell EMC ML3 is a six-step process.

1.

Upgrade the library and drive firmware to the current versions. The firmware can be found at www.Dell.com/support.

2.

Library-managed encryption on the library is already activated and cannot be deactivated.

If issues occur with the library-managed encryption on the library, go to http://www.dell.com/ tapeautomation for information on resolving the issue. If your issue is not resolved, contact Dell technical support.

3.

Configure library-managed encryption on your library.

4.

Install the IBM SKLM application on the server that is designated as the key manager. See IBM SKLM

Knowledge Center for information.

5.

Configure the IBM SKLM application. See IBM SKLM Knowledge Center for information.

6.

Start the IBM SKLM application. See IBM SKLM Knowledge Center for information.

Note:

All encryption settings must be configured or reverified in the drive after any library or drive reset. A new drive might be added or an existing drive might be swapped with another drive.

Library sharing

The library can be configured into one or more logical libraries that can be shared by multiple applications.

It is advantageous to be able to share a single physical library between heterogeneous or homogeneous applications. However, some applications (and some servers) do not allow for sharing a library between systems.

The library Management GUI provides two methods for logical library configuration.

1.

A quick configuration for a simple one logical library configuration

2.

An advanced configuration action for a multiple logical library configuration

Overview

17

The second method gives the ability to create configurations that enable the library to process commands from multiple heterogeneous applications (such as a Windows application) and multiple homogeneous

applications (for example, the same application run by several System p servers). See “Advanced library configuration” on page 55.

Path failover and load balancing

The path failover feature ensures the use of a redundant communication path when the primary path fails.

Command failures and time outs are costly. You want your library to run smoothly and efficiently. Path failover capabilities allow the device driver to resend a command to an alternate path. The alternate path can include another host bus adapter (HBA), Storage Area Network (SAN), or library control path drive.

The device driver initiates error recovery and continues the operation on the alternate path without interrupting the application.

Path failover and load balancing are built-in features that are enabled by using a purchased license. The path failover feature can be ordered from the factory, or you can order it as a field upgrade. The path failover feature is activated on the Management GUI. To order features, contact your Sales Representative or Business Partner.

Two types of path failover capabilities exist: control path failover (CPF) and data path failover (DPF). Control refers to the command set that controls the library (the

SCSI Medium Changer

command set on LUN 1 of the tape drives). Data refers to the command set that carries the customer data to and from the tape drives (the SCSI-3 Stream Commands (SSC) device on LUN 0 of the tape drives). Path failover means the same thing in both. Path failover is where redundancy is in the path from the application to the intended target (the library accessor or the drive mechanism), the device driver transparently fails over to another path in response to a break in the active path.

Both types of failover include host-side failover when configured with multiple HBA ports into a switch.

But CPF includes target-side failover through the control paths that are enabled on more than one tape drive. DPF includes target-side failover for the dual-ported tape drives that are supported by the library.

DPF includes load balancing of the HBAs because the channel is a data-intensive path (the control path carries little data, so load balancing is not an issue). The dynamic load balancing support optimizes resources for devices that have physical connections to multiple HBAs in the same machine. When an application opens a device where multiple HBA paths are configured, the device driver determines which path has the HBA with the lowest usage and assigns that path to the application. When another application opens a different device with multiple HBA paths, the device driver again determines the path with the lowest HBA usage and assigns that path to the second application. The device driver updates the usage on the HBA assigned to the application when the device is closed. Dynamic load balancing uses all HBAs whenever possible and balances the load between them to optimize the resources in the machine.

Both CPF and DPF require the use of the current device driver. They are supported exclusively with

products that bear the Dell logo on the operating systems that is indicated in Table 15.

Table 15 summarizes the differences between CPF, DPF, and load balancing.

Alerts and logging

The library sends alerts about the library and attached tape drives, and offers audit-logging to track user actions.

v

TapeAlert Support

: The tape library is compatible with TapeAlert technology, which provides error and diagnostic information about the drives and the library to the host application. The library provides this error and diagnostic information as TapeAlert flags that are reported to the application by the

SCSI LOG SENSE

command. See “TapeAlert flags” on page 95.

v

Email (SMTP - Simple Mail Transfer Protocol) Notifications

: The library can configure email

notification of library events. The library must have network access to an SMTP server. See “Locating

Management functions” on page 63.

v

Remote Logging (rsyslog)

: The library can send syslog (system log) notifications to a configured remote (rsyslog) server. When system events occur, the ML3 tape library creates a log of these events.

With this notification feature configured, the library sends a notification of the event to the syslog server. The syslog server keeps its own log of system events. (The syslog server is a customer-provided

server.) See “Locating Management functions” on page 63.

v

SNMP Support

: The Simple Network Management Protocol (SNMP) allows the library to send alerts over a LAN network to a monitoring server.

Occasionally, the library might encounter situations that you want to know about. These situations can be conditions that affect the library performance, such as an open door that causes the library to stop.

You might also want to log user actions, such as a cartridge move or export that is initiated from the

Management GUI. SNMP messages can alert you of these conditions.

The library provides a standard TCP/IP protocol that is called SNMP to send alerts about conditions over a TCP/IP LAN network to an SNMP monitoring server. These alerts are called SNMP traps.

Using the information that is supplied in each SNMP trap, the monitoring server (together with customer-supplied software) can alert operations staff of possible problems or operator interventions that occur. Many monitoring servers can be used to send email or pager notifications when they receive an SNMP alert. See the manual for your network management application.

The monitoring server must be loaded with systems management software that can receive and process the trap. SNMP supports a get and get-response mechanism for an operator to gather more information about a problem or query the library about its status. Through a monitoring server, the operator enters a "get" using SNMP to request information about the library. A get-response is the information that is provided in response to the get. This type of support generally requires an up-to-date library

Management Information Base (MIB). The SNMP server's MIB contains units of information that specifically describe an aspect of a system, such as the system name, hardware number, or communications configuration.

SNMP Notification Levels

Overview

19

SNMP provides various levels of notification about specific library events and user actions.

Inactive – No events are sent.

Critical – Only critical events are sent.

+ Warnings – Only critical and warning events are sent.

+ Configuration – Only critical, warning, and configuration events are sent.

+ Information – All events are sent.

Simple Network Management Protocol (SNMP) audit logging provides logging information about

specific tape library user actions. To configure SNMP, see “Locating Management functions” on page

63.

Host connectivity

Compatible servers and software

The library is supported by a wide variety of servers, operating systems, and adapters. There are many ways to determine the servers and software that support this library.

These attachments can change throughout the lifecycle of the product. To determine the newest attachments, or to get a comprehensive list of compatible software, do one of the following actions.

v For a list of compatible software, operating systems, and servers for LTO tape drives, see www.Dell.com/support.

Notes:

1.

Dell does not provide application software with this library. To order software, contact your sales representative, Business Partner, or an independent software provider.

2.

If you attach your library to a server with non-Dell software, contact your software vendor for a matrix of compatible hardware, software, firmware revisions, and adapter cards.

Note:

The library requires an HBA with multiple LUN supports. Also, multiple LUN supports must be enabled on the host computer. When multiple LUN supports are not enabled, the host computer can see the tape drive, but not the library.

Supported device drivers

Dell provides device driver support for the LTO tape drives, and the robotics in this library.

Dell maintains the current levels of device drivers and driver documentation on the web. Go to www.Dell.com/support and follow the steps to access this material.

|

|

IBM supports higher versions of the browsers if the vendors do not remove or disable functions that the product relies upon. For browser levels higher than the versions that are certified with the product, customer support accepts usage-related and defect-related service requests. As with operating system and virtualization environments, if IBM support cannot re-create the issue in the lab, the client might be asked to re-create the problem on a certified browser version to determine whether a product defect exists.

Defects are not accepted for cosmetic differences between browsers or browser versions that do not affect the functional behavior of the product. If a problem is identified in the product, defects are accepted. If a problem is identified with the browser, IBM might investigate potential solutions or workarounds that the client can implement until a permanent solution becomes available.

Surface debris is randomly collected from 10 areas of the data center on a 1.5 cm diameter disk of sticky electrically conductive tape on a metal stub. If examination of the sticky tape in a scanning electron microscope reveals no zinc whiskers, the data center is considered free of zinc whiskers.

Power cords

To avoid electrical shock, a power cord with a grounded attachment plug is provided. Use only properly grounded outlets.

Table 21 on page 26 lists the power cord part number, feature code, the country, or region

where the power cord is used, and the plug's standard reference. The last column in the

table contains an index number that you can match to a specific receptacle type in Figure 23 on page 30.

All power cords use an appliance coupler that complies with the International

Electrotechnical Commission (IEC) Standard 320, Sheet C13.

If the power cord that you receive does not match your receptacle, contact your local dealer.

Power cords that are used in the United States and Canada are listed by Underwriter's

Network requirements

The library supports an independent customer network. It is the customer’s responsibility to provide the proper length Ethernet cable for this connectivity.

The base module controller card has two Ethernet ports, which offer primary and redundant customer

network connectivity. See “Rear panel” on page 8.

These connections allow remote viewing and management of the library with the Management GUI.

Note:

Have your network settings handy to use for entering on the Operator Panel. Your network

settings can also be stored as hardcopy on Appendix A, “Library Configuration Forms,” on page 137.

The secondary Ethernet port might be used for service. Three models are available for connection: v No Ethernet port - Service personnel can connect a laptop to the customer network to use the

Management GUI with service login.

v Dedicated secondary Ethernet port - The secondary network port that is dedicated only for service personnel to connect a laptop directly to the library.

30

Dell EMC ML3 Tape Library: User's Guide

v Secondary Ethernet port - The secondary network port can be disconnected and service personnel can use it to connect a laptop directly to the library.

IP range selection

For internal communication between modules, the tape library uses an Ethernet connection with an internal IP address range. To prevent any conflict between the internal IP address range and the external

IP addresses, you must select the internal IP range. Choosing the Internal IP address range, and also entering the external IP address information is part of the initial setup of the library.

Host requirements

The library requires attachment to supported SAS or FC HBAs. See “Host connectivity” on page 20.

Static Sensitive

Risk of damage to devices v A discharge of static electricity damages static-sensitive devices or micro circuitry.

v

Proper packaging and grounding techniques are necessary precautions to prevent damage.

Follow these general guidelines.

v Check with a system administrator before the host computer is powered off.

v For a SAS library, confirm availability or install a SAS HBA that supports multiple LUNs.

v For a direct-attach Fibre Channel library, confirm availability of installation of an FC HBA.

v

For connection of a Fibre Channel library through a compatible switch, verify that sufficient ports are available.

Persistent binding to ensure SCSI ID assignment

When a server is booted, devices are discovered and assigned SCSI target and LUN IDs. It is possible for these SCSI assignments to change between boots. Some operating systems do not guarantee that devices are always allocated the same SCSI target ID after rebooting. Also, some software depends on this association, so you do not want it to change. The issue of SCSI ID assignment is addressed by persistent binding.

Persistent binding is an HBA function that allows a subset of discovered targets to be bound between a server and device. Implemented by a worldwide node name (WWNN) or worldwide port name

(WWPN), persistent binding causes a tape drive's WWNN to be bound to a specific SCSI target ID. After a configuration is set, it survives restarts and any hardware configuration changes because the information is preserved. If a drive must be replaced, the new drive assumes the WWNN of the old drive because the WWNN for the drive is location-dependent within the library. Because the WWNN does not change, persistent binding does not need changing, thus preventing a potential outage.

Overview

Multipath architecture

The multipath architecture feature of this tape library allows Open Systems applications to share the

robotics of the library. See “Library sharing” on page 17 for information.

The library features storage area network (SAN) ready multipath architecture. This architecture allows homogeneous or heterogeneous Open Systems applications to share the library's robotics without middleware or a dedicated server (host) acting as a library manager. The SAN-ready multipath architecture makes sharing possible by partitioning the library's storage slots and tape drives into logical libraries. Servers can then run separate applications for each logical library. This partitioning capability extends the potential centralization of storage that the SAN enables. Partitioning also provides investment protection if your application does not support the mixing of drive generations and media in the same logical library.

The multipath architecture of this library is designed to provide the capability to share the library robotics. The sharing is accomplished first by partitioning the library into multiple logical libraries (up to the number of drives installed). Then, each logical library is assigned its own separate and distinct drives, storage slots, and control paths. Input/output (I/O) slots are shared on a first-come-first-serve basis. This type of partitioning is designed to allow heterogeneous applications to share the library robotics independent of each other. Cartridges under library control are not shared between logical libraries, nor are they allowed to be moved between logical libraries. An example of heterogeneous sharing is a

Microsoft Windows application that is using the drive and storage slots of one logical library, while a

UNIX application uses the drive and slots of another logical library. See “Mixed drives” on page 12.

Multiple logical libraries

A library can be partitioned into multiple logical libraries to enable simultaneous data backup and restore tasks from different applications. For example, you can create multiple logical libraries so that is processes v Commands from Application 1 (about Department A) in Logical Library 1 v Commands from Application 2 (about Department B) in Logical Library 2 v Commands from Application 3 (about Department C) in Logical Library 3

In this configuration, the tape drives and cartridges of each logical library are dedicated to that library and are not shared among other libraries and subsequently other applications. Commands that are issued by the applications travel to the library through three unique control paths. So, the data processing for

Department A is confined to the tape drives and cartridges of Logical Library 1. Processing for

Department B is confined to the tape drives and cartridges of Logical Library 2, and so forth.

For applications that do not support mixed drive types and media within the same logical library, partitioning the library into multiple logical libraries provides the capability to keep them separate. For example, you can partition the following tape drives and their media into multiple and separate logical libraries: v LTO 8 v LTO 7 v LTO 6

Multiple control paths

With this tape library's multipath architecture, in addition to creating multiple logical libraries, you can configure any logical library to have more than one control path. A control path is a logical path into the library through which the library receives standard

SCSI Medium Changer

commands to control the library operations.

56

Dell EMC ML3 Tape Library: User's Guide

Multiple control paths reduce the possibility of a failure in one control path to cause the entire library to become unavailable. Also, when you configure more control paths, more library-sharing configurations and options are possible. Access to the library is on a first-come, first-served basis. Each control path for a logical library can accept commands while the library is in use by another control path.

Multiple control paths for control path failover

This tape library offers an optional control path failover feature. See “Library sharing” on page 17 and

“Path failover and load balancing” on page 18.

Use of the control path failover feature further reduces the possibility of a failure in one control path to cause the entire library to become unavailable.

The control path failover feature (feature code 1682) enables the host device driver to resend a command to a different control path for the same logical library.

Library partitioning

Libraries that contain at least two drives can configure two logical libraries. It is possible to configure up to 21 logical libraries in the library (up to the number of drives installed). In a partitioned library, the

Operator Panel reports only the status of logical library 1 in the main menu because of space limitations.

The user must go to the logical libraries status in the Operator Panel to get the information about the additional library partitions. The Management GUI provides a Logical Library Graphical View.

Partitioning of libraries

With full-height or half-height physical drives, physical numbering is bottom up for all drives. For

example, if you replace a half-height drive in Figure 22 on page 16, the drives are still numbered 1-4. If

you add a drive in any of the slots in between drives numbered 1 and 4, the physical numbering changes and is still numbered bottom up.

Important:

A full-height drive can be installed in a module in the lower two slots only.

Configuration of a 1-logical library system

A one logical library system contains all drives present in any drive positions, and it contains all the slots.

Configuration of multiple logical libraries

A library with multiple logical libraries must have a drive for each logical library and at least one slot.

Drives can be in any location in the library. It is best to have drives that are located near the slots that are assigned to the same logical library to minimize accessor movement and maximize performance.

SCSI element-addressing

A logical library assigns SCSI element addresses to drives, storage slots, I/O slots, and the accessor. For each element type (drive, storage, I/O), the SCSI element address can be viewed on the Management

GUI.

While SCSI addressing follows the same method as physical location-numbering, this action depends on the Advanced Logical Library configuration.

Drive numbering is from bottom to top. Storage slot-numbering is from left magazine (front to back, bottom to top) to right magazine (back to front, bottom to top). IO slot-numbering is from bottom to top.

Accessor is single number.

Installing

57

Note:

When the number of drives in your library are reduced, update the logical library configuration.

This action removes all event notifications that indicate a drive is missing.

Updating the logical library configuration might change the SCSI element addressing.

Verifying the host connection

To verify the connections between the host computer and the library

1.

Install the application software and drivers that are compatible with the library. Backup software packages might require extra software or licensing to communicate with the robotics.

2.

Verify the connection between the library and the host by using the host server’s operating system utilities. Or, use the Tape Diagnostic Tool (ITDT) to verify the communication between library and

host. See “The ITDT firmware update, dump retrieval and drive test tool ” on page 77.

See “Host connectivity” on page 20 for compatible servers and software.

The Management GUI

With the Management Graphical User Interface (GUI), you can monitor, configure, and operate most library functions from a web browser.

When possible, it is recommended that the Management GUI be used as the primary library interface.

The web interface provides access to more features, includes online help, and is easier to use.

Before the Management GUI can be used, you must log in and configure the library network settings

with the Operator Panel. This action can be done during Initial Setup. See “The Initial Setup process” on page 52.

Logging in with the Management GUI

1.

Open a supported web browser and enter the IP address of the library in the browser’s address bar.

2.

Select the user level and enter the password. Click Login.The ML3 RMU screen shows Welcome: User, superuser, admin, or service after a successful login. The user can log out at any time by clicking the

"logout" text in the upper right corner of the RMU page.

Note:

For initial login, select Adminstrator and the password is adm001 .

Note:

Only one person (on Operator Panel or Management GUI) can be logged in to the library at a time.

Methods of cleaning drives

Automatic cleaning of tape drives is disabled by default in the library. However, automatic cleaning of tape drives is recommended for this library. It is also possible to initiate manual or host cleaning methods.

The head of every tape drive in the tape library must be kept clean to prevent errors that are caused by contamination. To help you keep the drives clean, Dell provides a cleaning cartridge with the library. The library uses the cleaning cartridge to clean the drive with whatever cleaning method that you choose. In all methods, cleaning is done after the data cartridge is unloaded from the drive and before the next load.

It is the operator’s responsibility to monitor cleaning cartridge usage and replace cleaning cartridges as necessary. This tape library provides multiple ways to monitor and manage cleaning cartridges. If SNMP traps are enabled, a trap is generated when a cleaning cartridge expires. It is also possible to use the

Management GUI to monitor the cleaning cycles that remain on a cleaning cartridge and to the enable a setting that automatically ejects expired cleaning cartridges.

Three methods of cleaning are available.

Automatic cleaning

Automatic cleaning enables the library to automatically respond to any tape drive's request for cleaning and to begin the cleaning process. The cleaning process is transparent to any host application that uses the library.

Select Auto Clean to enable the auto cleaning feature. When enabled, the library automatically initiates a cleaning operation when media is unloaded from a drive that requires cleaning instead of creating a warning event when a drive requires cleaning. For reliable operation, enable Auto

Clean for each logical library and ensure that the library has a valid cleaning cartridge.

When a cleaning operation is initiated, the library first attempts to use an unexpired cleaning cartridge from the same logical library as the tape drive. If the logical library does not contain an unexpired cleaning cartridge, the library attempts to use an unexpired cleaning cartridge from a storage slot that is not assigned to a logical library. The library does not use a cleaning cartridge from a different logical library. When auto cleaning is enabled, ensure that each logical library has an unexpired cleaning cartridge. Or, place at least one unexpired cleaning cartridge in a storage slot that is not assigned to a logical library.

After the initial configuration, Auto Clean can be turned on or off by accessing the Logical

Library Wizard Expert Mode.

1.

Go to Library > Logical Libraries > Actions > Manage Logical Library (Expert Mode).

2.

Select the logical library, then click Edit.

3.

Click Next to go to the General Settings screen.

4.

Check or clear Auto Clean, then click Next on the subsequent screens.

5.

If a change was made, click Finish and the Logical Libraries are reconfigured. If no changes were made, click Cancel.

Managing

69

Note:

Dell recommends enabling the Auto Clean function on the library. With the Auto Clean function enabled, drive cleaning occurs automatically. The only time Auto Cleaning must be disabled is when your backup application requires that it has control.

Manual cleaning

Manual cleaning requires that you select a menu option from the Management GUI to clean one or more of the tape drives. Manual cleaning is always supported.

Host cleaning

Host cleaning enables the backup application to define and control the cleaning process.

Automatic and manual cleaning use the CLNxxx VOLSER.

Note:

For tape cartridge information, see “Supported tape cartridges” on page 16.

Accessing cartridges

Each magazine has a button that provides an easy way to open a magazine. See “Front panel” on page 7.

Each module can be configured to have a portion of the right magazine that is designated as an I/O station or this option can be disabled. To open the I/O station, press the magazine button for less than 3 seconds. To open the entire magazine, press the magazine button for more than 3 seconds.

Notes:

1.

If a magazine is opened, no other magazines or I/O stations can be opened.

2.

If during the magazine open process the magazine is not opened within 30 seconds, the magazine locks.

3.

The user must pull out the magazine, as the magazine does not eject.

The LED also provides an indicator of the current state of that magazine.

Configuring Library Managed Encryption (KMIP)

With the Key Management Interoperability Protocol (KMIP) Wizard, you can configure the use of KMIP key management servers with the library. Access the wizard from the Actions menu with the Manage

Encryption

option. The Library Managed Encryption Licensed Feature is already activated on your library, and cannot be deactivated. However, the feature must be configured before LME can be used.

Note:

Before you run the Encryption Wizard v Confirm that the Library Managed Encryption (KMIP) license is activated on the Settings > Library >

Licensed Features

page.

v Verify that the KMIP server is available on the network and is configured for use with this library. For information on configuring KMIP servers for use with the library, see the KMIP server documentation.

Note:

If you plan to use the IBM Security Key Lifecycle Manager (SKLM), go to “Related Publications” on page xxi for information on setup and configuration.

TapeAlert flags

This section is intended to provide information to the reader about the tape drive. All error code and diagnostic information can be accessed from the Management GUI of the library. The drive portion of the

Management GUI contains drive error codes. Therefore, it is not necessary to open the Library to access

the buttons on the drive. See “Locating Management functions” on page 63 for a complete description of

the Management GUI functions and displays.

TapeAlert is a standard that defines status conditions and problems that are experienced by devices such as tape drives, autoloaders, and libraries. The standard enables a server to read TapeAlert messages

(called flags) from a tape drive with the SCSI bus. The server reads the flags from Log Sense Page 0x2E.

Refer to the Dell Model ML3 Tape Library SCSI Reference?? for library and drive TapeAlert Flag information.

This library is compatible with TapeAlert technology, which provides error and diagnostic information about the drives and the library to the server. Because library and drive firmware might change periodically, the SNMP interface in the library does not require code changes if devices add more

TapeAlerts that are not supported today. However, if this issue occurs the Management Information Block

(MIB) is written to minimize impact to the SNMP monitoring station. At the time of this writing, the

TapeAlert flags correctly represent TapeAlerts that are sent. The MIB file must not be taken to mean that all traps that are defined in the MIB are sent by the library or that they will be sent in the future.

Sense data

When a drive encounters an error, it provides sense data as a response to the host. Refer to the Dell Model

ML3 Tape Library SCSI Reference?? for library sense data information. Refer to the Dell LTO Ultrium Tape

Drive SCSI Reference?? for tape drive sense data information.

In addition, you can use the Tape Diagnostic Tool (ITDT) to further examine data and determine errors.

See “The ITDT firmware update, dump retrieval and drive test tool ” on page 77.

Drive Error Codes: Single-character display (SCD)

If you encounter problems while the tape drive is running, refer to “Finding event information” on page

73.

The SCD display appears on the inside back of an installed library and can be seen through the front window of an expansion unit. It is seen on the lower center of a full-height drive. Each drive has a status

100

Dell EMC ML3 Tape Library: User's Guide

light and single-character display, that when visible provides drive informational and error conditions.

The single-character display shows either a single character, a dot (in the lower right of the display), or both.

Note:

The SCD can be seen through the windows of expansion units, and for full-height drives only. If you have a base unit without expansion units, or if you have half-height drives, the SCD cannot be seen.

“Single-character display (SCD) codes” lists the codes for error conditions and informational messages. If

multiple errors occur, the code with the highest priority (represented by the lowest number) displays first.

When the error is corrected, the code with the next highest priority displays until no errors remain.

The SCD is blank during normal operation.

Single-character display (SCD) codes

Table 39 gives descriptions of the errors and messages that pertain to the drive. For troubleshooting tips,

see “Troubleshooting Guide” on page 73.

v Make note of the SCD error code before a cartridge is removed or the SCD error code is cleared.

v If an error occurred with a cartridge in the drive, eject the cartridge from the drive with the library

Management GUI (see “Locating Management functions” on page 63).

Attention:

If the drive detects a permanent error and displays an error code other than SCD , it automatically runs a drive dump. If you force a drive dump, the existing dump is overwritten and data can be lost. After you force a drive dump, do not turn OFF the power to the drive or you might lose the dump data.

Replacing a Base or Expansion controller card

CAUTION:

v

Parts can be damaged by electrostatic discharge. Keep parts in electrostatic containers until needed. Ensure that you are properly grounded when static sensitive components are touched.

v

You must power off the library to install or replace this part or damage can occur.

Important:

Do not replace both the base chassis and the Base Module controller card with repair components in the same procedure. The firmware does not allow the library to operate if both components are replaced at the same time. Critical library information is saved in the controller card and within the chassis. When one is replaced, the data from the original component is transferred to the repair component. If both the base chassis and Base Module controller are replaced, you must power cycle the library between component replacements.

Saving the configuration

See “Locating Management functions” on page 63 for instructions on saving configuration settings to a

file with the Management GUI or with the Operator Panel. This procedure is done when a Base Module controller card is replaced, or as an extra precaution when both the controller card and the module are replaced.

Note:

Do not do a Save Configuration on a library that is in a failed state. Save the configuration on a working library only.

Powering off the library

Verify that all host processes are idle, then power off the library from the front panel. Depress Power and hold it for 5 seconds. If the library does not complete a soft shutdown, depress and hold Power for 10 seconds.

Important:

Under normal circumstances, when the library is powered off by using the front Power, the robot automatically parks and locks into the Base Module behind the Operator Panel. If you are given a choice during the power down procedure, choose the default park position. To protect the spooling cable or other sensitive parts, the accessor must be in the Base Module before any modules or drives are removed from the library. If it is not, follow the procedure for returning the accessor to the base module.

See “Returning the accessor to the Base Module” on page 127.

Data cartridges

Use the LTO data and cleaning tape cartridges designed for your model of library.

When tape is processed in the cartridges, LTO Tape Drives use a linear, serpentine recording format. The native data capacity and recording format of LTO data cartridges is as follows:

Table 45. Cartridge data capacity and recording formats

Type

Gen 8

Gen 7

Gen 6

Native Data Capacity Recording Format

12000 GB (30000 GB at 2.5:1 compression)

Reads and writes data on 6656 tracks,

32 tracks at a time

6000 GB (15000 GB at 2.5:1 compression) Reads and writes data on 3584 tracks,

32 tracks at a time

2500 GB (6250 GB at 2.5:1 compression) Reads and writes data on 2176 tracks,

16 tracks at a time

The first set of tracks is written from near the beginning of the tape to near the end of the tape. The head then repositions to the next set of tracks for the return pass. This process continues until all tracks are written and the cartridge is full, or until all data is written.

The cartridge door (

▌2▐

in Figure 86) protects the tape from contamination when the cartridge is out of

the drive. The tape is attached to a leader pin (

▌3▐

in Figure 86) behind the door. When the cartridge is

143

inserted into the drive, a threading mechanism pulls the pin (and tape) out of the cartridge, across the drive head, and onto a non-removable take-up reel. The head can then read or write data from or to the tape.

The write-protect switch (

▌4▐

in Figure 86 on page 143) prevents data from being written to the tape

cartridge. For more information, see “Write-Protect switch” on page 147.

The label area (

▌5▐

WORM (Write Once, Read Many) cartridges

Certain records retention and data security applications require a Write Once, Read Many (WORM) method for storing data on tape. LTO drives that are supported by the library enable WORM support when a WORM tape cartridge is loaded into the drive.

WORM media

Because standard read/write media are incompatible with the WORM feature, a specially formatted

WORM tape cartridge (see Figure 87 on page 145) is required. Each WORM cartridge has a unique,

worldwide cartridge identifier (WWCID), which comprises the unique CM chip serial number and the unique tape media serial number. Ultrium WORM media are two-tone color and silvery gray.

Note:

All Dell drive firmware allows the use of WORM media.

144

Dell EMC ML3 Tape Library: User's Guide

Figure 87. LTO Data and WORM tape cartridges

Data security on WORM media

Certain built-in security measures help ensure that the data that is written on a WORM cartridge do not become compromised. For example v The format of a WORM Tape Cartridge is unlike that of standard read/write media. This unique format prevents a drive that lacks WORM-capable firmware from writing on a WORM tape cartridge.

For LTO 8, native data capacity is 12000 GB and compressed data capacity is 30000 GB.

v When the drive senses a WORM cartridge, the firmware prohibits the changing or altering of user data that is already written on the tape. The firmware tracks the last appendable point on the tape.

WORM media errors

The following conditions cause WORM media errors to occur.

v Information in the servo manufacturer's word (SMW) on the tape must match information from the cartridge memory (CM) module in the cartridge. If it does not match, a media Error Code 7 posts on the drive's single-character display (SCD).

v Inserting a WORM tape cartridge into a drive that is not compatible with WORM causes the cartridge to be treated as an unsupported medium. The drive reports a media Error Code 7 .

Cleaning cartridge

With each library, a specially labeled Cleaning Cartridge is required to clean the drive head. The drive itself determines when a head must be cleaned. It alerts you by lighting the Clean Drive (amber LED) on the Operator Panel. Dell recommends the use of the Auto Clean function on this library. When enabled, the library retrieves the cleaning cartridge that is contained in the library, inserts it in the drive that needs cleaning, cleans the drive, then returns the cleaning cartridge to its home slot. To clean the head manually, insert a cleaning cartridge into the tape load compartment The drive completes the cleaning automatically. When the cleaning is finished, the drive ejects the cartridge, and the library turns off the

Clean Drive

LED. See “Methods of cleaning drives” on page 69.

Note:

The drive automatically ejects an expired cleaning cartridge.

The Dell Cleaning Cartridges are valid for 50 uses.

Labeling tape cartridges

The device contains a bar code reader that reads the tape labels and stores the inventory data in memory.

The device then provides the inventory information to the host application, Operator Panel, and

Management GUI. Having a bar code label on each tape cartridge enables the bar code reader to identify the cartridge quickly, thus speeding up inventory time. Make it a practice to use bar code labels on your tape cartridges.

Appendix B. LTO media

145

A proper bar code label includes the media ID in the last 2 characters of the bar code. The library does not load an incompatible cartridge, based on the bar code media ID, into a tape drive. For example, the library does not load a cartridge that is labeled as LTO 3 into an LTO 6 tape drive. This action saves the time that is needed to load the cartridge and have the tape drive reject it.

A bar code label contains: v A volume serial number (VOLSER) that is human-readable.

v A bar code that the library can read.

Note:

In a library environment, it is highly recommended to use bar code labels for performance and easily identifiable reasons. This library requires bar code labels.

Your host software might need to track the following information by using the associated bar code.

v Date of format or initialization v

Tape's media pool v Data residing on the tape v Age of the backup v Errors that are encountered while the tape is used (to determine whether the tape is faulty).

Important:

Misusing and misunderstanding bar code technology can result in backup and restore failures. Use only high-quality labels. Self-printed labels are not recommended as they are often a source of bar code reading issues.

When read by a library's bar code reader, the bar code identifies the cartridge's VOLSER to the library.

The bar code also tells the library whether the cartridge is a data cartridge or cleaning cartridge. The bar code includes the two-character media-type identifier

Lx

, where x equals 6, 7, or 8 for data cartridges or

W, X, or Y for WORM cartridges.

L identifies the cartridge as an LTO cartridge, and the number or letter

represents the generation of cartridge for that cartridge type. Figure 88 on page 147 shows a sample bar

code label for the LTO Tape Cartridge.

Tape cartridges are ordered with the labels included or with custom labels.

To determine the complete specifications of the bar code and the bar code label, contact your sales representative.

LTO tape cartridges have a recessed area on the face of the cartridge next to the write-protect switch. Use this area for attaching the adhesive-backed bar code label. Place the label only in the recessed label area

(see

▌5▐

in Figure 86 on page 143). A label that extends outside of the recessed area can cause loading

problems in the drive.

146

Dell EMC ML3 Tape Library: User's Guide

Attention:

Do not place any type of mark on the white space at either end of the bar code. A mark in this area might prevent the library from reading the label.

Figure 88. Sample bar code label on the LTO 8 Tape Cartridge. The volume serial number (LTO123) and bar code are printed on the label.

Important:

The bar code label must be applied as shown, with the alphanumeric characters on top and the bar codes on the hub side (bottom). Never apply multiple labels onto a cartridge because extra labels can cause the cartridge to jam in a tape drive.

Guidelines for bar code labels

Apply the following guidelines whenever bar code labels are used.

v Do not reuse a label or reapply a used label over an existing label.

v Before you apply a new label, remove the old label by slowly pulling it at a right angle to the cartridge case.

v Use peel-clean labels that do not leave a residue after it is removed. If glue residue is on the cartridge, remove it by gently rubbing it with your finger. Do not use a sharp object, water, or a chemical to clean the label area.

v Examine the label before it is applied to the cartridge. Do not use the label if it has voids or smears in the printed characters or bar code. A library 's inventory operation takes much longer if the bar code label is not readable.

v

Remove the label from the label sheet carefully. Do not stretch the label or cause the edges to curl.

v Position the label within the recessed label area (see

▌5▐

in Figure 86 on page 143).

v With light finger pressure, smooth the label so that no wrinkles or bubbles exist on its surface.

v Verify that the label is smooth and parallel, and has no roll-up or roll-over. The label must be flat to within 0.5 mm (0.02 in.) over the length of the label and have no folds, missing pieces, or smudges.

v Do not place other machine-readable labels on other surfaces of the cartridge. They might interfere with the ability of the drive to load the cartridge.

Write-Protect switch

All rewriteable data cartridges have a write-protect switch to prevent accidental erasure or overwriting of data. Before a cartridge is loaded into the device, make sure the write-protect switch on the front of the cartridge is in the desired position.

The position of the write-protect switch on the tape cartridge (see

▌1▐

) determines whether you can write to the tape. If the switch is set to: v Slide the switch to the right to write-protect the cartridge. An indicator, such as a red mark or small padlock, is visible showing that the cartridge is write-protected.

Appendix B. LTO media

147

v Slide the switch to the left to allow the device to write data to the cartridge.

If possible, use your server's application software to write-protect your cartridges (rather than manually setting the write-protect switch). This setting allows the server's software to identify a cartridge that no longer contains current data and is eligible to become a scratch (blank) data cartridge. Do not write-protect scratch (blank) cartridges; the tape drive is not able to write new data to them.

If you must manually set the write-protect switch, slide it left or right to the wanted position.

Handling the cartridges

Attention:

Do not insert a damaged tape cartridge into the drive. A damaged cartridge can interfere with the reliability of a drive and might void the warranties of the drive and the cartridge. Before a tape cartridge is inserted, inspect the cartridge case, cartridge door, and write-protect switch for breaks.

Incorrect handling or an incorrect environment can damage cartridges or their magnetic tape. To avoid damage to your tape cartridges and to ensure the continued high reliability of your LTO Ultrium Tape

Drives, use the following guidelines.

Providing training

v Post procedures that describe appropriate media handling in places where people gather.

v Ensure that anyone who handles tape is properly trained in handling and shipping procedures. This training includes operators, users, programmers, archival services, and shipping personnel.

v Ensure that any service or contract personnel who complete archiving procedures are properly trained in media-handling procedures.

v Include media-handling procedures as part of any services contract.

v Define and make personnel aware of data recovery procedures.

Ensuring proper packaging

v When a cartridge is shipped, use the original or better packaging.

v

Always ship or store a cartridge in a jewel case.

148

Dell EMC ML3 Tape Library: User's Guide

v Use only a recommended shipping container that securely holds the cartridge in its jewel case during transportation.

v

Never ship a cartridge in a commercial shipping envelope. Always place it in a box or package.

v If you ship the cartridge in a cardboard box or a box of a sturdy material, ensure that you

– Place the cartridge in polyethylene plastic wrap or bags to protect it from dust, moisture, and other contaminants.

– Pack the cartridge snugly; do not allow it to move around.

– Double-box the cartridge (place it inside a box, then place that box inside the shipping box) and add

padding between the two boxes (see Figure 90).

Figure 90. Double-boxing tape cartridges for shipping

Proper acclimation and environmental conditions

To ensure the longest possible life for your data cartridges, follow these guidelines.

v

Before you use a tape cartridge, acclimate it to the operating environment for 24 hours or the time necessary to prevent condensation in the drive. The time varies, depending on the environmental extremes to which the cartridge was exposed. If the data cartridge was exposed to temperatures outside the specified ranges, stabilize the cartridge at room temperature for the same length of time it was exposed to extreme temperatures or 24 hours, whichever is less.

v Ensure that all surfaces of a cartridge are dry before it is inserted.

v Do not expose data cartridges to direct sunlight or sources of heat, including portable heaters and heating ducts.

v Do not place data cartridges near sources of electromagnetic energy or strong magnetic fields such as computer monitors, electric motors, speakers, or X-ray equipment. Exposure to electromagnetic energy or magnetic fields can destroy data and the embedded servo code that is written on the media by the cartridge manufacturer, which can render the cartridge unusable.

v Use only the data cartridges that are designated for your device.

v Clean the tape drive when the Clean drive LED is illuminated.

v Do not drop a cartridge. Excessive shock can damage the internal contents of the cartridge or the cartridge case itself, making the cartridge unusable.

v Place identification labels only in the designated area on the cartridge.

v

Maintain the conditions that are described in “Environmental and shipping specifications for tape cartridges” on page 151.

Appendix B. LTO media

149

Attention:

Do not degauss LTO data cartridges! These data cartridges are pre-recorded with a magnetic servo signal. This signal is required to use the cartridge with the LTO tape drive. Keep magnetically charged objects away from the cartridge.

Completing a thorough inspection

After a cartridge is purchased and before it is used, complete the following steps.

v Inspect the cartridge's packaging to determine potential rough handling.

v When a cartridge is inspected, open only the cartridge door. Do not open any other part of the cartridge case. The upper and lower parts of the case are held together with screws; separating them impairs the usefulness of the cartridge.

v Inspect the cartridge for damage before it is used or stored.

v Inspect the rear of the cartridge (the part that loads first into the tape load compartment) and ensure

that no gaps appear in the seam of the cartridge case. . If gaps appear in the seam (see Figure 91), the

leader pin might be dislodged.

Figure 91. Checking for gaps in the seams of a cartridge

v Check that the leader pin is properly seated. .

v If you suspect that the cartridge was mishandled but it appears usable, copy any data onto a good cartridge immediately for possible data recovery. Discard the mishandled cartridge.

v Review handling and shipping procedures.

Handling the cartridge carefully

v Do not drop the cartridge. If the cartridge drops, slide the cartridge door back and ensure that the leader pin is properly seated in the pin-retaining spring clips..

v

Do not handle tape that is outside the cartridge. Handling the tape can damage the tape's surface or edges, which might interfere with read or write reliability. Pulling on tape that is outside the cartridge can damage the tape and the brake mechanism in the cartridge.

v Do not stack more than six cartridges.

v Do not degauss a cartridge that you intend to reuse. Degaussing makes the tape unusable.

Environmental and shipping specifications for tape cartridges

Before you use a tape cartridge, acclimate it to the operating environment for 24 hours or the time necessary to prevent condensation in the drive. The time varies, depending on the environmental extremes to which the cartridge was exposed. If the data cartridge was exposed to temperatures outside the specified ranges, stabilize the cartridge at room temperature for the same length of time it was exposed to extreme temperatures or 24 hours, whichever is less.

The best storage container for the cartridges (until they are opened) is the original shipping container.

The plastic wrapping prevents dirt from accumulating on the cartridges and partially protects them from humidity changes.

When you ship a cartridge, place it in its jewel case or in a sealed, moisture-proof bag to protect it from moisture, contaminants, and physical damage. Ship the cartridge in a shipping container that has enough packing material to cushion the cartridge and prevent it from moving within the container.
