Does the output of dmesg give any relevant output relating to the tape driver?
If it is on a separate scsi card and the driver is not loaded yet (check 
with lsmod) load it (asuming adaptec scsi) modprobe aic7xxx

If this doesn't help try loading the tape module. modprobe st


Every program has two purposes one for which
it was written and another for which it wasn't
I use the last kind.
