Drive Assessment test Details/Device specific test
The LTO drive assessment test is the most important test in the L&TT diagnostics suite.
The test is used to assess the health of a tape drive, providing a clear pass or fail result
in about 15 minutes and determines if the drive or autoloader is Fit for Purpose (FFP). Description
CAUTION: This test is destructive and will overwrite data on the media that is present
in your product. For additional information about the LTO drive assessment test, see
NOTE:
•
Requires a good tape that is overwritten as part of test.
• L&TT offers the test applicable to your tape drive. The test fails to run with a tape
is partitioned.
•
In the L&TT test menu, the Assessment test may be prefixed with the device type.
For example: SDLT Assessment test.
• The Drive Assessment test can be stopped before it completes. To abort the test
from the GUI, click Abort Test. To abort the test from the CSI, use the Ctrl-A key
combination.
•
The textual output of the test will give the ultimate summary — PASS or FAIL. The
test results can be emailed to HP support for confirmation. For instructions on how
to perform this test, see
“Running tests and device-specific utilities” (page 29) or
“Running the tests (CSI)” (page 50) or “Running tests (CLF)” (page 64) .

Library specific:
◦
If the test is being run on an autoloader or library and the device is configured
in circular or stacker mode (dependent on the particular autoloader), when an
unload command is received from the host (such as is issued with the Assessment
test), the autoloader or library moves the next available cartridge into the drive.
If the magazine is not loaded with data cartridges and cleaning cartridges in
the correct order to meet the needs of the test, the test will fail. HP recommends
using the single cartridge process when running the Assessment test on an
autoloader or library.
• If the drive to be tested in part of an autoloader or library, the autoloader or library
should be in random mode prior to running the test.
•
If there is an issue with the backup or restore process and the assessment test passes
the drive, further diagnostics are needed to find the root cause of the issue elsewhere
in the system.
The test contains four main sections:
•
Analyze the drive logs—The test pulls over 60 logs from the drives and analyzes
them with about 20 rules and 130 sub-rules. Any issues considered critical in a
support ticket, which uses the same rules, will cause the test to fail the drive at this
point. Other issues, such as cleaning requests or the detection of host polling, will
be noted in the test output for informational purposes.
•
Test the load and unload mechanism—The cartridge is unloaded, partially ejected,
and reloaded. Any potential mechanical failures are flagged.
