Sorry to argue a rather academic point here, since the problem is now
solved. However, the message saying "Detected scsi XXX at srX" is a
kernel message that is giving you the "normal" or "default" name of the
block device file that it would use. The actual block device could be
named /dev/fred for as much as it would matter, as long as the major &
minor numbers and permissions are correct. As I previously said, in
RedHat, these block devices are in fact named /dev/scd0, scd1, etc. And,
on bootup, the kernel will give you a message like you quoted. It has no
way of knowing that on RedHat that message is in fact incorrect. --jw
