SCSI tape buffer test
This test write logical blocks of data to the internal buffer on the tape drive. The same
logical blocks of data are then read from the tape drive buffer and compared to the
original data. This test does not alter the data on the tape in the tape drive in any way.
Data integrity is not compromised by this test. If the tape drive does not have an
internal buffer, this test cannot be selected.
SCSI tape self test
Most SCSI tape drive manufacturers provide a diagnostics test in the firmware on the
SCSI tape drive. Choose this option to execute the diagnostic tests that reside on the
SCSI tape drive. If this test is successful, you are assured that the tape drive is
operating in accordance with the drive manufacturer's specifications.
To run the test, select SCSI Tape Self Diagnostics Test and press <Enter>. Choose the
parameters on the screen and choose Continue. The SCSI Tape Self diagnostics test
cannot be aborted. You must wait until the entire disk self test completes.
SCSI tape write test
This test erases old data and writes new data to the tape cartridge. This test issues
SCSI write commands to the tape drive block by block sequentially.
Warning:
This test destroys all data on the tape cartridge.
The test parameters are Repeat Count (number of times to run this test) and Quick
Test (test only 1% of the tape cartridge). Select the tape drive to be tested. Select the
starting and ending data block to be tested or the percentage of the tape cartridge to
be tested. Choose Continue to run the test.
SCSI tape read test
This test reads sequential logical blocks from the SCSI tape. The reading terminates
when end of medium marker, end of partition marker, or blank data is encountered.
This test issues the SCSI Read command with a 6-byte CDB. Select
SCSI Tape Read Test
and press <Enter>. A default parameter screen appears:
