HP StoreEver TapeAssure Software - Manual (Page 111)

Options There are two recommended options to control the behavior of the test:
•
Test Type (default is Read Only) —
To run the Read Only (data quality assessment) test, set the
Test Type
option to Read Only.
◦
◦ To run the Overwrite (media assessment) test, set the Test
Type
option to Overwrite.
•
Amount of Media to Test — The default amount of data read
varies by drive/tape generation (1 GB of data for DAT72 and 2
GB of data for DAT160 / DAT320) and is enough for a valid read
margin calculation to be performed. The data read is sampled
across the data on the media between BOD (beginning of data)
and EOD (end of data). The larger the value for this option, the
greater amount of data is read at each sample. This is done to
enable an effective test to be performed in a reasonably short period
of time — approximately 8 minutes using the default value.
To fully check all of the data written on the media, set the Amount
of Media to Test
option to Entire Tape, but note that this will
take more time.
The following test options allow the test to be run outside of the standard
operation parameters. However, do not use these options unless advised
to do so by HP Support:
•
Check WORM integrity (default True) — When this option is
set to True, the Read Only test can be run on a WORM cartridge,
which checks the integrity of the WORM media and verifies that
no one has tampered with the WORM cartridge. This test does not
allow writing to a WORM cartridge.
•
Ignore cleaning requests (default False) — If the tape drive
to be tested is requesting cleaning, clean the drive before running
the test. However, if a cleaning cartridge is not available, you can
bypass this check by setting this option to True. In that case, the test
will report that non-standard test options were used so the results
of the test cannot be guaranteed.
•
Allow Unqualified Drives (default False) — Normally, this
test can only be run if the drive has recently passed the DDS Drive
Assessment Test, ensuring that the drive is in good condition. This
option is used to bypass this check, which is not recommended
because any failures cannot necessarily be attributed to the media.
When to run Run this test with the Test Type option set to Read Only (default)
when you want to check that the data on tape is of a high quality.
Run this test with the Test Type option set to Overwrite when you
want to check that the media itself is in good condition.
Average duration Test times vary greatly depending on drive type, media quality, and
options selected. With the default test options, the average time is
approximately 8 minutes for a healthy drive with a good tape.
Other notes This test will overwrite all data on the media if the Test Type option
is Overwrite. If the drive to be tested is part of an autoloader, the
autoloader should be in random mode prior to running the test.
Available for DAT72, DAT160, and DAT320 (pre and post-merger HP drives only).
