Brian,
I can confirm that in general, the support for SCSI under Redhat is good. I have two RH9 systems with different SCSI controllers and both are fully functional for tape drives, disks, scanner, and CD-RW.
It seems contradictory that dmesg reported recognizing the tape drive and assigning it to a device, yet you have no /proc/scsi/scsi file.
I've attached three files/snippets you may find useful. These are:
1. Sample SCSI related portion of dmesg output 2. Sample /proc/scsi/scsi file 3. Portion of /usr/src/linux/.config pertaining to SCSI configuration
This last file will probably be somewhat different from yours, because it's for a 2.4 kernel.
Good Luck,
Scott C.
