Solution

One Character Display shows 'A' ..... Here is the meaning and recommended actions.....note that write performance tests will overwrite data on the tape.

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 Status Light flashes amber. The error code may clear when you cycle power 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 using IBM ITDT tape drive analysis program:

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.

2. If the Test Cartridge & Media diagnostic fails, replace the media. If it runs successfully, clean the failing drive and run the drive diagnostics. If the test runs successfully but the execution time is significantly longer than the ″Approximate Run Time″ as shown in the IBM LTOx Setup Operator and Service Guide, run “Function Code F: Write Performance Test”. 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 “Function Code 1: Run Drive Diagnostics” and run “Function Code F: Write Performance Test”. If the Write Performance Test fails, replace the media and exit maintenance mode.If the drive diagnostics run successfully, run the Test Cartridge & media diagnostic 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.
