Error Code
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 diagnostics
(see
2. If the Test Cartridge & Media diagnostics fail, replace the media. If it runs successfully, clean the
failing drive and run the drive diagnostics (see

than the Approximate Run Time, run
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

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.

Encryption Error. Displayed when the drive detects an error associated with an encryption operation. If the
problem occurred while the tape drive was writing data to, or reading data from, tape:
1. Check the host application to ensure the host application is providing the correct encryption key.
2. Check the operation of the tape drive by resetting the drive and running POST.
3. Check the media.
If the problem occurred while the tape drive was running POST or diagnostics, replace the drive.
The error code clears with the first attempted write/read after the encryption key is changed, or when the
drive is placed in maintenance mode.

Refer to the IBM Tape Device Drivers Encryption Support documentation and the IBM LTO
Ultrium Tape Drive SCSI Reference documentation for the Sense Data returned for an
encryption operation.
Retry the encryption operation after the host application problems have been resolved.
Refer to the error code displayed on the SCD if the drive reset and POST fails.
Retry the encryption operation if the drive reset and POST complete without errors.
Ensure the correct media is being used. Data encryption is supported with LTO Ultrium-7 and
Ultrium-8 Data Cartridges only.
Retry the encryption operation with the tape cartridge in another encryption enabled drive.
Replace the media if the problem repeats with the same tape cartridge in multiple drives.
