6 Tests and utility functions
L&TT provides numerous tests for analyzing storage hardware. These tests are grouped into two
categories: diagnostic tests and performance tests. The performance tests are built into the program,
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 be used to perform non-diagnostic utility functions, such as rewinding a tape, recalibrating
a tape head, or exercising a tape-moving robot arm.
L&TT uses the following types of SCSI scripts:
•
Script-based tests and utilities are based on scripts that are stored in the scripts directory
in the L&TT installation directory. The script-based test and utility files can have the *.tst,
*.plg
, *.pmg *.smd, or *.rul extension.
•
SCSI utility scripts provide access to generic SCSI operations. These scripts have the *.scc
or *.cps extension.
L&TT includes three types of utilities, each of which is accessed with a different method.
•
Device-specific utilities are accessed from the Utility screen and operated like the tests. See
Running the tests (GUI) (page 40)
for information on running the device-specific utilities.
•
Device connection independent utilities are accessed from the Utilities
→Run Utilities menu.
See
Running the device independent utilities (page 169)
for information on running the device
connection independent utilities.
•
SCSI utility scripts are run from the Utilities
→Run Script menu. See
for information on running the SCSI script utilities.
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.
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.
The only tests supported in Ethernet I/O mode are:
•
LTO Drive Assessment test
•
LTO Media Assessment test
•
Device Analysis
•
Device Self Test
If the drive has firmware is older than 015.313 you will not be able to run any test except Device
Analysis in Ethernet I/O mode.
Utilities are not supported in Ethernet mode.
Diagnostic tests
CAUTION:
Some tests are destructive to data on the media. When a test is destructive to data, this is indicated
in the test description. To prevent data loss, use media that is either new or that contains unimportant
data that can be erased. Do not attempt to perform a test unless you are thoroughly familiar with
its usage, or have been instructed to do so by HP support personnel.
