SCSI tape drive unrecognized

["Robert G. (Doc) Savage" <dsavage@peaknet.net>]

Having a senior moment here. Don't remember how to get a SCSI tape drive
recognized as /dev/st0. 

Situation:  IBM laptop in docking station. Docking station has Symbios
53C810-type SCSI host adapter installed and connected to external DAT
drive. The HA and drive work perfectly with a Win2K drive in the laptop.
Since this is a post-install RH8 configuration, I've had to manually add
the following lines to /etc/modules.conf: 

   # SCSI host adapter (docking station only) 
   alias scsi-hostadapter0 sym53c8xx_2 
   # 
   # Tape drivers (docking station only) 
   alias st0 st 
   # OnStream driver 
   #alias osst0 osst 
   # 

For some reason none of these modules load at boot time, so I must load
them after bootup: 

   # insmod sym53c8xx_2 
   Using /lib/modules/2.4.18-14/kernel/drivers/scsi/sym53c8xx_2/sym53c8xx_2.o
   # insmod st 
   Using /lib/modules/2.4.18-14/kernel/drivers/scsi/st.o 

Trouble is, the DAT drive at SCSI ID=6 does not appear in
/proc/scsi/scsi: 

   # cat /proc/scsi/scsi 
   Attached devices: 
   Host: scsi0 Channel: 00 Id: 00 Lun: 00 
     Vendor: TOSHIBA  Model: DVD-ROM SD-R2002 Rev: 1129 
     Type:   CD-ROM                           ANSI SCSI revision: 02 

and I can't access the a tape loaded in the drive: 

   # tar tfv /dev/st0 * 
   tar: /dev/st0: Cannot open: No such device 
   tar: Error is not recoverable: exiting now 

I'm looking for an entry in /proc/scsi/scsi like: 

   Host: scsi1 Channel: 00 Id: 06 Lun: 00 
     Vendor: Archive ...... 

Any ideas about what I'm missing???  I've tried using
"scsi-hostadapter1" instead of "scsi-hostadapter0" in modules.conf with
no change. 

I need to do a full tape backup of my [damaged] RH8 installation before
I can move up to Phoebe2.
