Table 10. Error codes on the single-character display (continued)
Error Code Cause and Action
A
Degraded operation. The tape drive determined that a problem occurred that 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 status LED flashes amber. The error code might 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
and Media diagnostic (see “Function Code E: Test cartridge and media” on page 29).
2. If the Test Cartridge and 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 16 and
“Function Code 1: Run drive diagnostics” on page 19).
Record the time 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 significantly 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. 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 16
and “Function Code 1: Run drive diagnostics” on page 19).
Record the time 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 significantly 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. If the drive diagnostics run successfully,
run the Test Cartridge and Media diagnostic (see “Function Code E: Test cartridge and media”
on page 29).
2. If the Test Cartridge and 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
16.
The error code clears when you clean the tape drive or place it in Maintenance Mode.
