Table 11. LTO-5 Tape Drive Error Codes (continued)
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 Status LED flashes amber. 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 76).
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 Tape Drive” on page 91 and “Function Code 1: Run Drive
Diagnostics” on page 73). 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. 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 76. 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
Tape Drive” on page 91 ). 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. 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 76. 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 (see “Function
Code E: Test Cartridge & Media” on page 76).
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.
The error code clears when you clean the tape drive or place it in maintenance
mode.
