assuming your scsi controller is detected... the st modules should be
loaded by the kernel.

if you do a dmesg |less then you should seems something like this
SCSI subsystem driver Revision: 1.00
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec aic7895 Ultra SCSI adapter>
aic7895C: Ultra Wide Channel A, SCSI Id=7, 32/253 SCBs
scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec aic7895 Ultra SCSI adapter>
aic7895C: Ultra Wide Channel B, SCSI Id=7, 32/253 SCBs
blk: queue df5e1c14, I/O limit 4095Mb (mask 0xffffffff)
(scsi0:A:4): 10.000MB/s transfers (10.000MHz, offset 15)
Vendor: HP Model: C1537A Rev: L610
Type: Sequential-Access ANSI SCSI revision: 02
then a bit later something like:
st: Version 20030406, bufsize 32768, max init. bufs 4, s/g segs 16
Attached scsi tape st0 at scsi0, channel 0, id 4, lun 0
if you see that it's all good.
then you can do:
[root@acad-backup etc]# mt -f /dev/st0 status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (50000):
DR_OPEN IM_REP_EN
and it should report the current state of the drive.
then it's more a question of deciding what and how to backup which is a
seperate issue.
