That certainly looks like a bad tape cartridge or tape drive.  I would look into the tape library logs and review any messages there.

Check syslog(/var/adm/messages) if any relevant SCSI error was logged.

SOLUTION/WORKAROUND:
A reboot of the media server can cleared all the SCSI reservations/conflicts thus allowing the drives to stay up until the hardware issue is addressed.  Please contact the hardware manufacturer for assistance in resolving any hardware configuration issues.
