What happens if you cat /proc/scsi/scsi?  I get something like the following:

> cat /proc/scsi/scsi 
Attached devices: 
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: SEAGATE  Model: ST15150W         Rev: 0023
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 02 Lun: 00
  Vendor: HP       Model: C1533A           Rev: 9503
  Type:   Sequential-Access                ANSI SCSI revision: 02

This at least lets you know if the system sees the thing.  The next question
is: does your kernel have SCSI tape support?  Cat /proc/devices, do you see
something like:

 > cat devices
Character devices:
  1 mem
  2 pty
  3 ttyp
  4 ttyS
  5 cua
  7 vcs
  9 st

Is /dev/st0 correct (ie: major 9, minor 0)?:

> ls -la /dev/st0
crw-rw----   1 root     disk       9,   0 Oct 23  1999 /dev/st0
