Bugger. I get none of the above:

-bash: lsscsi: command not found
# ls -l /dev | grep sg

*sigh*
I'd like to help these people out, but well, there *seems* to be a
hardware issue. Their admin, now departed, claims backups to tape were
working. Backups to disk are working, but not tape. Nothing in
bacula-sd.conf refers to any tape drive. Nothing in the command history
refers to the tape drive.
They have 8x400GB volumes on disk and they're out of space.
Mysteries.
