206 Troubleshooting the Tape Library
T010
T010- Drive Unload Failed
Description GUI Description: A drive failed to unload/eject a tape cartridge, preventing
the robot from picking and moving the cartridge.
Explanation: The library is expecting the tape drive to achieve an unloaded
state, but the tape drive does not succeed and reported an error when
unloading/ejecting the tape cartridge for picker access. This RAS ticket is
ONLY displayed if the tape drive was actually instructed to perform an unload
operation and the drive's command response informed of an issue. In the
case where the library controller code is determining that the drive is still busy
for a defined wait time period and the unload request is not sent to the tape
drive, this ticket shall not be generated, but rather the request to unload shall
be denied as an illegal request. In the case where the command is issued but
the library times out waiting for an unload response, ticket
T053 shall be
reported.
Detection Scenarios • A SCSI Move Medium was issued, but the drive does not achieve an unload/
eject state after being instructed to unload and eject.
• A UI command was issued to unload or move from a drive, but the drive does
not achieve an unload/eject state after being instructed to unload and eject.
Root Causes The tape drive reports a failure and fails to unload a tape cartridge after the
library issued an unload command.
Service Resolution
Steps 1 See also: DR003 - Resolve Drive Eject Failure on page 367.
2 Use the Details option in the RAS ticket to identify the suspect tape drive
sled. Open the main door and inspect drive for any stuck media. If media is
present, attempt an emergency power-on reset by holding the eject button
down for 5 seconds, which will reset the drive and attempt to eject the media.
3 Clear all RAS tickets and retry the original operation with another piece of
known good media.
Possible CRUs/FRUs Note: Read and perform all resolution steps before dispatching any parts.
