Generally this happens when the job ends abnormally and BackupExec cannot write the markers associated with normal termination
You will need to re-label the tape (and lose whatever data is currently on it) to be able to use this volume again
Dear Sir:
Please check the properties of the Tape Drive and of each of your "end marker..." tapes, to see if they have soft or hard read or write errors.
If they do, and the numbers exceed the 100s or the 1000s, either your tapes are faulty or the tape drive is slowly damaging them. This you can verifiy by getting a new tape and running a backup job and checking the errors after the job, on the new tape. For the drive you can previously reset the cleaning statistics in properties.
I would suggest to copy the jobs on the "end marker tapes..." with a duplicate to another location such as disk, and log erasing them to get them fresh and without errors. But first, check what I metioned above.
Regards,
