DR016: Resolve Prevent/Allow Media Removal

Problem:
The library has been commanded to perform a cartridge move from a drive, but the drive is currently preventing
any media removal due to having received a SCSI Prevent/Allow Media Removal command to prevent a tape
cartridge removal. The library cannot unload and eject the tape cartridge from the drive until the host application
issues a SCSI Prevent/Allow Media Removal command to allow a tape cartridge unload operation.
Troubleshooting Step:
Determine which host currently has a prevent media removal set. Use the host application or OS functionality to
clear the Prevent mode.

DR018: Resolve Drive Cleaning Requirement

Problem:
A drive has reported that it requires cleaning. The drive cannot be used for normal operations again until it is
successfully cleaned. This problem should be addressed differently based on your system setup.
Troubleshooting Steps:
There are two cases to consider:
1. Library-controlled or host-controlled cleaning is enabled.
v Prior to the tape drive requesting cleaning, the cleaning process should have been triggered already when the
tape drive recommended cleaning. However, since the tape drive is now requesting to be cleaned, a valid,
non-expired cleaning tape may not have been available for library initiated or host controlled cleaning. Verify
that cleaning tapes are properly configured and not expired.
v Perform a manually initiated cleaning operation for the tape drive as specified in the user documentation.
2. Library-controlled automatic cleaning is disabled.
Since automatic library initiated tape drive cleaning operations are not enabled, perform a manually initiated
drive cleaning operation for the tape drive as specified in the user documentation. Note that in the case of RAS
ticket "T045: Drive TapeAlert 20 - Clean Now" on page 6-22, the drive may require multiple drive cleaning
operations.
3. Choose one of the following options:
v Select Close to close the ticket now.
v Select Exit to leave the ticket open for future troubleshooting.
v Select Back to return to the Diagnostic Resolution.

DR019: Resolve Open Access Door

Problem:
A library main access door appears to be open. Either an access door is opened, or module termination is
interrupted.
There are two basic scenarios to recover from:
1. Door open DID NOT interrupt a library MOVE MEDIA.
2. Door open DID interrupt a library MOVE MEDIA.
