I also think the tape itself is fine, since this has happened many times
now.. I don't think all of the tapes are bad.
I'm also using Adaptec 29160 SCSI HBA to connect to the tape library.
I wonder what would be the best way to debug this..
Now after bacula hang the first time I'm not able to get it running again..
it always just hangs when I do "sta storage".. and nothing happens for real.
I guess the tape drive/library is in some bad state? Or the SCSI driver?
Let's see if rebooting the server gets it running again..
