I need some help getting my backup tape drive configured in Red Hat
7.3

This is running on a Compaq ML330 server box, using the Compaq SDT-
10000 tape drive. I just finished setting the box up to run as a PDC,
and decided that it was time to get the backup working. Unfortunatly,
when using the mt command to retension the tape, I just get a "No
such device" error. Using the Hardware Broswer in KDE, it shows the
tape drive with a device id of /dev/st, and even shows the model, so
something sees the drive, and knows what it is, but I still can't
make the drive do anything.

Any tips/hints/pointers to good info?
