Error code
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 SCD continues to indicate an error and the status light
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
Media diagnostic (see "Function code E: Test cartridge and media" on page 35).
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 23 and
"Function code 1: Run drive diagnostics" on page 28).
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 36. 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
23 and "Function code 1: Run drive diagnostics" on page 28).

The tape drive needs to be cleaned. Clean the tape drive. See "Cleaning the drive head" on page
