Well, I have a "test bus" that I hang either a tape stacker/tape drive
pair, or a 4-bay full of tape drives, and do the 
	echo "scsi delete-single-device 0 0 1 0" > /proc/scsi/scsi
	echo "scsi delete-single-device 0 0 2 0" > /proc/scsi/scsi
	...
	echo "scsi add-single-device 0 0 1 0" > /proc/scsi/scsi
	echo "scsi add-single-device 0 0 2 0" > /proc/scsi/scsi
and then run the script.  Sometimes you get problems allocating
the st driver buffers, but usually it works okay...
