Or until Red Hat goes under due to too many people using the parasitic clone 
products that do nothing to support Red Hat's bottom line.

I've seen elsewhere online that some vendors who's products are certified to 
run under RHEL are refusing to give support to folks using clones when the need 
arises.

Granted I'm not using the same hardware as you, but I've got a changer hanging 
off of my Red Hat ELAS 3 box and I found the changer and the tape drive itself 
(they are two separate devices on my system) by using the tapeinfo -f /dev/sgn 
command where n was an integer that I kept incrementing until it came back with 
what appeared to be reasonable representations of my devices, turned out to be 
on /dev/sg3 (the changer itself) and /dev/sg4 (the tape drive itself).

After I found them, I made symlinks for /dev/changer which points to /dev/sg3 
and /dev/tape which points to /dev/nst0. The mtx and mt commands will default 
to these devices (/dev/changer and /dev/tape) respectively.

Good luck.
