Hi.  Thanks for your reply. I was able to resolve this yesterday by simply reseating both fibre connections to the back of the TL2000.  I read somewhere that one of the drives also has the changer "role".  If that isn't right, and I saw both tape devices before (from a lsscsi -g or cat /proc/scsi/scsi), what are your thoughts on why the changer would show up after reseating the cables?
TL2000 is fibre zoned to one of my servers.  I can see the tape drives, also visible when I do cat /proc/scsi/scsi. TL2000 is set for Random.  I also restarted the TL2000 but that didn't change anything. How do I get the medium changer to show up as a scsi device? Is this lack of functionality a Linux problem or a TL2000 problem? Thanks in advance for any insights you can provide.
