I'm seeing the following error in my joblog:
Code: Select all
BackupSrvFileToTape failed
Tape fatal error.
Incorrect function.
Tape write error
Tape fatal error.

In the agent log:

The tapelib I'm using is a HP MSL 2024 with two HP Ultrium 6-SCSI drives in it. It's connected through SAS with the backup/tapelib server.

My case # is 1419800.

Hello Jonathan,

I assume its a block size issue and this solution might help. However, I suggest consulting with the support team before applying the said regkey.
