To discover why 2.2.1 can't see one of your discs it might be helpful
if you could quote what the kernel says as it detects the SCSI devices
in each case (dmesg when it boots; copy from the screen otherwise, I
suppose).
To boot with just the one disc it would be good if there were a way of
getting the kernel to recognise target 4 as /dev/sdb even when target 3
is not detected by supplying a cunning argument at the SILO prompt.
Does anyone know how to do this?
I glanced through http://www.linuxhq.com/HOWTO/BootPrompt-HOWTO-4.html
without seeing a solution, but I did see something else which might be
helpful for some people: apparently you can specify "max_scsi_luns=1".
