Is the drive working as expected?
If you suspect that your drive is not working properly, run the Assessment test for your drive. If the
drive passes the Assessment test, then it is considered to be working well with the tape you provided.
If the drive fails the Assessment test, the problem might be caused by:
•
Poor media. Run the test again with a different tape.
•
Dirty heads. Use a cleaning tape.
If the drive still fails after trying both of the above then the issue is most likely with the drive. In this
case, contact HP support and have the results of the test ready.
For more information about the Assessment test, see Assessment test (page 100) .
Is the drive firmware up to date?
It is important to keep the drive firmware up to date. Firmware updates include improvements to
resolve known field issues. For more information about using L&TT to update firmware, see
Uploading firmware to devices (GUI) (page 38) or Uploading firmware to devices (CSI) (page 72) .
Is the drive performing as expected?
If you believe that your drive is not performing to specification, L&TT has three tests to measure
performance:
•
Drive Performance test—Measures the transfer rate of the drive, HBA, and cabling. See Using
the Drive Performance test (page 132) .
•
System Performance test—Consists of two separate tests:
Backup Performance test—Measures the data source transfer rate from the disks or network
for backup. ◦
◦ Restore Performance test—Measures the data restore transfer rate to the disks or across
the network for restores.
For more information about using these tests, see Using the System Performance test (page 137) .
These tests measure the actual transfer rates, enabling you to determine if a performance problem
exists, and if so, whether the problem is with the drive or the system. In most cases, system
performance is the limiting factor. For detailed information about finding and fixing performance
issues, see

Is the media in good condition?
If you suspect a problem with media, L&TT provides several tests that check media integrity. Click
the following links for detailed information about each test:
•
Media Analysis test
•
Media Validation test
•
MO Media Validation test
•
Read Media IDs test
•
SDLT Tape Edge Damage (TED) test
If the media fails one or more of the above tests, and the drive is considered to be in good condition
(see
Is the drive working as expected? (page 195) ), then it is likely that the media is bad. In this
case, you can:
•
Make a backup of that data to another tape if the data is still available on your system.
•
Perform the Media Analysis test in a different drive. It is possible that the drive that wrote the
data was also suspect, but a different drive might be able to read the data.
•
Contact HP support for assistance.
