Symptoms

We have 4 drives that are dedicated for NDMP backup/restore jobs. Currently any job we send there errors out with an Error 98 from Netbackup.  All 4 drives seem to have this.  Other Library operations seem to be ok but these 4 drives are not functioning.

Also once the jobs fail the tape is not ejected.  The only way to get the tape out of the drive is to manually eject it by opening the door to the library and pushing the eject button on each drive.

NOTE: This problem seems to happen when the drive writes small amounts of data in a job (close to 1 gb)

- The drives are getting logically stuck tapes only on drives used by netbackup
- The tapes manually dismounted by opening the doors and pressing the unload button on the drives, then manually put the cartridges on storage cells.
