Ok, this is a changer, right?  Is it bombing right when one tape would be full?  

I think what's happening is that the bacula daemon doesn't have rights to send the hardware command to the changer to make it change the tape.  The dirty way to fix this is to have the bacula daemon run as root, but a better way would be to create a user for the daemon and give it the rights it needs.  

I'm sure you've been here: http://www.bacula.org/rel-manual/Autochanger_Support.html#SECTION000291000000000000000

here's another good one:  http://www.freebsddiary.org/digital-tl891.php

Good Luck, Travis

Check for a firmware update for the tape drive.
Most of the time Dell uses ADIC libraries and IBM drives, and IBM drives work best with IBM tapes. Try using an IBM tape.
Try retentioning the tapes.
Also will not hurt to try loading a cleaning tape.
Configure it so that the same bus is not used for both tape and disk.

davidmichel's points were good.  One thing I've run into is sometimes the latest firmware updates can be the problem if the support files in projects like Bacula haven't been updated yet.  Make sure your firmware is not too new for Bacula support.

hmm, 114t comes up as a changer when i look at dell.  you sure?  if it has the robot arm in it you need to load the autochanger stuff for bacula.

Unit Attention is usually just a normal informational type message. Any time a drive is powered on, a tape is loaded, a tape is ejected a Unit Attention will happen. It is a problem when the SCSI bus is hung and a Unit Attention is sent to reset the bus and regain communication with the device.
