Note that the above shows your SCSI devices on sym0, which is the
onboard Symbios SCSI card, not the Compaq RAID adapter.

To the original poster: Compaq usually has two adapters in their 
machine: the Compaq RAID adapter, and an onboard SCSI adapter that
is used for the CDROM/tape device.  It's possible that you need 
to have "device sym0", or "device ahc0" in your kernel in order to
recognize this controller.

The Array Controller does not present a SCSI interface to the system,
so I'm not really sure that you can connect a tape drive to it.
(but I may be wrong here)
