Tape Library fails to successfully mount and read tape media
Job involving tape media either fails or fails to make progress reporting subject error
Most likely hardware related. Tape device needs cleaning, repair, or replacment. No empty slots available for tape.
In some cases, insufficient job resources (CPU, Bandwidth) caused by hung jobs can generate this error.
For command-line/DB iDA multi-stream restores the system caches the tape reservation and does not unmount tape immediately for performance reasons. This can cause subject error.
Check for high CPU usage on MediaAgent. If found, reboot MediaAgent to clear hung processes.
Check library for errors, sufficient slots, clean media device requests. Clean/repair/replace tape device or free up media slots if needed.
For command-line/DB iDA multi-stream restores, add the following additional setting to disable restore optimization by releasing tape device reservations immediately so that other streams can access it.
