About this guide
1Introduction
HP StorageWorks Library and Tape Tools (L&TT) is a collection of storage hardware management and
diagnostic tools for Nearline Tape, Nearline Tape Automation, and Nearline Archival products. L&TT
assembles these tools into a single, convenient p rogram.
IMPORTANT:
This user guide is intended for L&TT version 4.2. Certain features from previous versions of L&TT are no
longer supported with this version and are therefore not documented here. HP strongly recommends
that you install and use the latest version of L&TT. However, if you must use an earlier version, refer to
the online help that is bundled with that version of the program.
Software features
L&TT offers the following features:
• Installation Check—L&TT guides you through a basic installation check of your product. The
software assists the user in choosing an appropriate HBA and SCSI IDs, ensuring that the device
is
detected by the system, and verifying key device functionality.
• Device Identification—L&TT clearly identifies the storage products connected to the system, along
with key information on product configuration and status.
• Troubleshooting Tests—L&TT provides various tests to verify product functionality or to isolate
product issues. Tests include device self-tests, read/write tests on drives, exerciser tests for
autoloaders and libraries, and specific device utilities.
• Firmware Upgrades—L&TT provides a convenient way of updating product firmware, enabling
users with an Internet connection to take advantage of ongoing enhancements. The software can
be
configured to check the Web automatically for firmware updates for connected devices, or
users can manually check the Web for updates if the automatic update feature is not desired.
If
updated firmware is available, the program notifies the user, and the updates can easily be
copied to the system. With libraries, users can upgrade the library and the embedded drive
firmware in thesameoperation.
• Support Ticket Generation—If you experience a problem with a storage product, L&TT can
generate a suppor t ticket that includes essential information for troubleshooting the problem.
As an
alternative to phone support, you can e-mail the support ticket to a support center for
assistance. This information streamlines the support process and enables the suppor t staff to
better serve you if a support call is made later.
When a support ticket for a device is generated, L&TT performs a Device Analysis test on the device.
The s upport ticket contains generic information about a device, as well as the results of the Device
Analysis test. The Device Analysis test can be performed by itself, but HP recommends generating a
support ticket because the resulting data is presented in a more useful format.
• Automatic Notification of Web Updates—If a connection to the Internet is present and web
updates are enabled in the tool preferences, L&TT automatically informs you of the following
updates, if available, each time the program is started:
•New versions of L&TT
•New firmware files for connected devices
• New device-specific functionality for connected devices

Introduction
2 Installation
This chapter outlines the procedure for installing L&TT on a Microsoft® Windows®, Novell NetWare,
HP-UX, HP Tru64, Linux, or HP OpenVMS platform. The Windows version of L&TT uses a graphical user
interface (GUI). All other versions of the program use a command screen interface (CSI).
The information in this chapter and in subsequent chapters is presented for both the GUI and CSI versions
of L&TT. When using an electronic version of this documentation, click the appropriate link at the
beginning of the chapter to quickly jump to the section of documentation that applies to your op erating
system (OS) or user interface.

One drawback of ASPI is that USB drives are not supported. If you have USB drives, you must
use the Miniport driver.
Beginning with version 4.0, L&TT supports Microsoft Storport technology. Storport is a new storage
driver model created by Microsoft for Windows Server 2003 and future Windows® operating
systems. Storport offers a higher performance architecture and better Fibre Channel compatibility
in Windows systems. If Storport drivers are installed, L&TT automatically uses Storport when you
select Miniport I/O.
NOTE:
ASPI is not officially supported by Windows Server 2003. However, in most cases, it will function
properly. If ASPI is installed with Windows Server 2003, L&TT can make use of it if the ASPI I/O
mode is selected. However, HP recommends that you use the default NT MiniPort I/O option
with Windows Server 2003.

3 Getting Started with L&TT
This chapter describes how to start L&TT and the basic operation of the software. This chapter is divided
into
two sections: one for using L&TT in a GUI environment (Windows) and one for using L&TT in a
CSI environment (NetWare, HP-UX, Tru64, Linux, and OpenVMS). To quickly jump to the appropriate
section, click one of the following links:
Starting L&TT (GUI)

Programs > HP StorageWorks Library and Tape Tools > HP L&TT.
Using the Scan Mode Selection feature
When L&TT starts, the splash screen opens. The splash screen gives you the o pportunity to exit the
application if it was started unintentionally and before any SCSI bus activity occurs. This prevents the
program from interfering with any backup or other storage applications that currently may be running.

Use the Select All, Remove All, Select,and Remove buttons to select devices. Selected devices are
displayed in the right panel of the screen, and only selected devices will be scanned and identified by
L&TT. Devices that are skipped will not be displayed in the Device List on the L&TT main screen.
After selecting all of the devices that you want L&TT to scan and identify, click Continue to perform the
scan and proceed to the L&TT main screen. L&TT saves the list of selected devices so the next time you
start L&TT and display the Saved/Manual Scan screen, L&TT displays all of the previously selected
devices in the right panel.
Additional device scan considerations
After the initial scan is complete and saved, future full system hardware scans become unnecessary in
most cases. You must perform a hardware scan after any of these actions have occurred (Windows in
NT

• After the hardware configuration has been changed
• After power cycling more than one of the tape drives on the system
• After updating firmware in more than one of the tape drives on the system
To perform a hardware scan, exit and restart L&TT. On the splash screen, select the Hardware scan option
rather than Saved scan. If you do not do this, the Windows operating system might get out of sync with the
L&TT saved scan because Windows device rediscovery assigns new logical device names to the devices.

4 Firmware Man agement
The Firmware Management functionality of L&TT provides a convenient way to easily upgrade the
firmware ofconnecteddevices.Libraryfirmwareandfirmwareofdriveswithinthelibrariescanbe
upgraded as well.
L&TT uses special firmware files that associate the firmware with a particular product. This feature prevents
the
user from downloading the wrong ima ge and ensures that the downloaded firmware is the same as
or a
newer revision of the current device firmware.
CAUTION:
Do not use L&TT to update firmware on a tape library or devices within a tape library that is managed
with HP StorageWorks Command View for Tape Libraries Software (Command View TL). Firmware
update operations for these devices must be performed using Command View TL, as documented in the
HP StorageWorks Interface Manager and Command View for Tape Libraries Software user guide
L&TT is used to update firmware on a managed library, the management station will be out of sync with
the actual firmware revision number and will report a firmware mismatch. Furthermore, if you attempt to
use L&TT to update firmware on a partitioned library, L&TT reports an invalid command error.

Using a firmware update (FUP) tape
The preferred method for updating drive firmware is by using the L&TT application. Firmware can be
updated on both Windows and non-Windows platforms. However, there are some cases where L&TT
is not
available, or otherwise cannot be used (for example, with an unsupported operating system). In
these cases, a firmware update (FUP) tape can be created and used for the purpose of updating drive
firmware. Inmostcases,FUPtapescanbecreatedbyHPandsuppliedtoendusers,orbecreated
by the end users themselves.
When using L&TT to update firmware, there are protections in place to ensure that only the correct
firmware isdownloadedtothedrive.ThereisnosuchprotectionmechanismwithaFUPtape,socare
must be taken to use the FUP tape only with the drive it is intended for.
Performing the update
The procedure for using a FUP tape varies depending on the drive type, and in some cases, whether
or
not the drive is in an autoloader or library. Click the appropriate drive type below to get the details

5 Tests and utility functions
L&TT provides numerous tests for analyzing storage h ardware. These tests are g rouped into two
categories: diagnostic tests and performance tests. The performance tests are built into the p rogram, but
several of the diagnostic tests are SCSI script-based. A SCSI script is a sequence of SCSI commands
sent to a device, usually for the purpose of testing the device’s functionality. SCSI scripts can also b e
used to perform non-diagnostic utility functions, such as rewinding a tape, recalibrating a tape he ad, or
exercising a tape-moving robot arm.
L&TT uses the following types of SCSI scripts:
• Script-based tests are tests based on scripts that are stored in the scripts d irectory in the L&TT
installation directory. The script-based test files can have the *.tst, *.plg, *.pmg *.smd,
or *.rul
• SCSI utility scripts provide access to generic SCSI operations. These scripts are accessed by
selecting Run Script... from the Utilities menu and have the *.scc or *.cps extension. For
more information, see Using the utility functions.
NOTE:
Each script file contains information that tells L&TT which devices it is designed to support. When a
device is selected, the Tests screen displays only tests that are applicable to that particular device.
extension.
NOTE:
All scripts have a digital signature and cannot be altered. If they are altered in a text editor, L&TT
displays an error message stating that the digital signature is not correct.

options to mod ify the default behavior of the test.
• Allow Overwrite (default False)— To run the Read Only (Backup
Assessment) test, set the Allow Overwrite option to False,orleave

option to True.
• Amount of Media to Test — The actual amount of data read

unable to report that the Backup is FFP, but it will be a very good
indication of the health of the backup. To fully test the Backup fitness,
set the Amount of Media to Test option to Entire Tape,which will

The other test options allow the test to be run outside of the standard operation

disk file system (simulating a backup), and the restore pre-test measures the write performance of the
disk file system (simulating a restore). Use these tests in conjunction with the Drive Performance Test to
identify any system bottlenecks. The backup pre-test is read-only and is safe to run on any part of your
file system.

Using the Move test
The Move Test performs a move command in a library or autoloader using source and destination
elements specified in the test options. When the move command completes, a second move command
returns the cartridge to its original location. This sequence can be repeated using an o ptional loop count.
The following options are available for this test:
