I'll exend Brad's comments:
1) is this a RAID controller?  If so, then you could have hardware mirroring
(RAID 1) and you would only see one device
2) is this narrow or wide SCSI?  Narrow SCSI has 8 devices available, 0 to
7, with 7 *usually* being reserved/allocated for the SCSI adaptor itself at
ID 7.  Narrow SCSI has 15 devices available, 0 to 14, but 7 is still
*usually* being reserved/allocated for the SCSI adaptor itself at ID 7. 

HTH,
Mike

What kind of SCSI controller do you have?  All SCSI controllers
I've ever seen have always had a setup available that you can get to
before bootup.

I'd try to get into the setup ROM and see what the controller knows
about the drive(s).
