Error Code Cause and Action
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 might clear when you cycle power to the tape drive or place
it in Maintenance mode.
To determine whether the problem is with the drive hardware, or the tape media, complete these
procedures:
1. If possible, run the tape cartridge in a different drive. Replace the media if the operation in the
other drive fails, and
6
or
7
displays. If the operation succeeds, run the Test Cartridge &
Media diagnostic test (see “Function code E: Test cartridge & media” on page 29).
2. If the Test Cartridge & Media diagnostic test fails, replace the media. If it runs successfully,
clean the failing drive and run the drive diagnostic tests (see “Cleaning the drive head” on
page 19 and “Function code 1: Run drive diagnostics” on page 24).
When you begin this test, the diagnostic test begins the loop sequence. Time the first loop by
pressing Unload once to stop the diagnostic test after the completion of the first loop, then
record the time that it takes for the test to complete. Compare the recorded time with the
"Approximate Run Time". If the test runs successfully but the execution time is longer than the
"Approximate Run Time", run “Function code F: Write performance test” on page 30. If the
Write Performance Test fails, replace the media and exit Maintenance mode. If the drive
diagnostic tests run successfully, complete 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, complete these procedures:
1. Clean the failing drive and run the drive diagnostic tests (see “Cleaning the drive head” on
page 19 and “Function code 1: Run drive diagnostics” on page 24).
When you begin this test, the diagnostic test begins the loop sequence. Time the first loop by

diagnostic tests run successfully, run the Test Cartridge & Media diagnostic test (see “Function
code E: Test cartridge & media” on page 29).
2.
If the Test Cartridge & Media diagnostic test fails, replace the media. If it runs successfully,
complete the operation that produced the initial drive error.
3. If the problem persists, replace the drive.
C
The tape drive must be cleaned. Clean the tape drive. See “Cleaning the drive head” on page 19.
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.
