A Degraded operation. The tape drive determined that a problem occurred which degraded
the operation of the tape drive, but it did not restrict continued use. If the problem persists,
determine whether the problem is with the drive or the media.
Note: The drive is usable, though the Single-character Display continues to indicate an error
and the Fault light flashes. The error code may clear when you cycle power to the
tape drive or place it in maintenance mode.
To determine if the problem is with the drive hardware, or the tape media, perform the
following procedures:
1 If possible, run the tape cartridge in a different drive. If the operation in the other drive
fails and 6 or 7 displays, replace the media. If the operation succeeds, run the Test
Cartridge & Media diagnostic (see Function Code E: Test Cartridge & Media
on page 57).
2 If the Test Cartridge & Media diagnostic fails, replace the media. If it runs successfully,
clean the failing drive and run the drive diagnostics (see Cleaning the Drive Head
on
page 43 and Function Code 1: Run Drive Diagnostics
on page 49).
Once you begin this test, the diagnostic begins the loop sequence. Time the first loop by
pressing the Unload button once to stop the diagnostic after the completion of the first
loop, then record the time it takes for the test to complete. Compare the recorded time
with the “Approximate Run Time” above. If the test runs successfully but the execution
time is significantly longer than the “Approximate Run Time”, run Function Code F: Write
Performance Test on page 58. If the Write Performance Test fails, replace the media and
exit maintenance mode. If the drive diagnostics run successfully, perform the operation
that produced the initial drive error.
3 If the problem persists replace the drive.
If it is not possible to run the tape cartridge in a different drive, perform the following
procedures:
1 Clean the failing drive and run the drive diagnostics (see Cleaning the Drive Head
on
page 43 and Function Code 1: Run Drive Diagnostics
on page 49).
2 If the Test Cartridge & Media diagnostic fails, replace the media. If it runs successfully,
perform the operation that produced the initial drive error.
3 If the problem persists replace the drive.
C The tape drive needs to be cleaned. Clean the tape drive. See Cleaning the Drive Head
on
page 43.
The error code clears when you clean the tape drive or place it in maintenance mode.
d Fiber AL_PA conflict. Two drives on fiber loop have the same AL_PA. Modify the tape drive
AL_PA to eliminate the conflict. NOT SUPPORTED ON THIS DRIVE.
