Going back to your earlier posting showing the /proc/scsi/scsi output, and
assuming the library is on the same bus as the drive, consider running the
following:

for lun in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
do
echo scsi add-single-device 1 0 5 $lun > /proc/scsi/scsi
done

If the library is on the same controller/target/bus as the tape drive, but
just a different LUN, that should locate it for you.

Note that you'd need to do this each time you reboot. I've generally found
setting up an init script to be more reliable than the vagaries of kernel
rebuilds and then remembering to reapply changes on later builds...

Cheers,

Preston.
