Dell may make the library, but IBM made the drives. The LTO3 drives in my Overland library are from HP.

That's the SCSI backplane in your server -- it has nothing to do with the library.

Well, sg2 is the tape drive itself and sg7, like I said, is the backplane in the server. I'm guessing that the changer is on the same SCSI ID as the tape drive but on another LUN. Add 'options scsi_mod max_luns=255' to /etc/modprobe.conf, remake the initrd, and reboot. Let us know if that helps.
