Given that the tape drive is attached to the Adaptec 2940U SCSI controller, doesn't st have to eventually send SCSI commands to the aic7xxx driver????
Here are the relevent modules after I:
depmod -ae modprobe st
[root@kjc386 root]# lsmod st 29964 0 (unused) ide-scsi 11120 0 sd_mod 13004 2 sr_mod 16888 0 (autoclean) cdrom 31040 0 [sr_mod ide-cd] aic7xxx 130996 1 scsi_mod 102968 6 [st sg sr_mod ide-scsi aic7xxx sd_mod]
But, there is still no mention of the tape drive in /proc/scsi/scsi, nor when I:

st shouldn't be aliased to your aic7xxx. That causes modprobe to try to load the aic driver when you try to load st.
Remove the alias, run depmod -ae, then modprobe st
this is the output of lsmod on my system:

And from the below, you can see st.o is a module that stands apart from the scsi drivers. That's what recognizes your tape drive and activates /dev/st0
locate /st.o /lib/modules/2.4.18-3smp/kernel/drivers/scsi/st.o /lib/modules/2.4.18-3/kernel/drivers/scsi/st.o /lib/modules/2.4.18-3debug/kernel/drivers/scsi/st.o /lib/modules/2.4.20-28.7/kernel/drivers/scsi/st.o /lib/modules/2.4.18-27.7.xdebug/kernel/drivers/scsi/st.o /lib/modules/2.4.20-28.7smp/kernel/drivers/scsi/st.o /lib/modules/2.4.25/kernel/drivers/scsi/st.o /usr/src/linux-2.4.25/drivers/scsi/st.o

I have the following in my modules.conf:
alias st0 aic7xxx
(it used to be: alias st0 BusLogic )
Even so, when I "modprobe st", "mt -f /dev/st0 status" still tells me:
/dev/st0: No such device

have you loaded the st module? (modprobe st)

Can someone please explain why my Adaptec 2940U Ultra Wide SCSI controller (AutoSCSI in the controller BIOS) shows me that my Archive Python DAT tape drive is on Channel 0, id 3, but when I boot RedHat's linux-2.4.20-28.9, the aic7xxx module only sees my disk drive on channel 0, id 6? Yes, both devices are plugged into the narrow bus, and auto termination is configured on the controller, and the devices are in the same order as before (see below).
This used to work fine on my BusLogic BT-948 controller [which I had to stop using on my new motherboard (because the ABIT AF7 motherboard won't finish POST with the BusLogic BT-948 controller plugged into a PCI slot.....)]
