Rick,
aic7xxx=no_probe had no effect. Grub.conf has no special parameters
passed to the kernel. The scsi cable has one terminator connection at
the end, one drive that is first in the chain and the rest are open
connectors.
This server has had RH 8,9 and FC4. It's just odd that this scsi driver
would 'fail' so far down the line of OS upgrades.
Thanks for the suggestions. If there's a rabbit to be pulled out of the
hat then I'm all ears.
Todd
