Don't know to recover from this, but if I had several hard disk on my
server and something depended on the kernel detecting them in order, I
would try using devfs (device filesystem).

Is not that hard to setup, seems stable by now and you will never get your
disks messed again. Under devfs naming, a SCSI disk is identified by the
adapter and bus where it is attached, and by its SCSI and LUN numbers (the
"same" for IDE disks). So the kernel will always identify the disks in the
same way.

For example my master disk on the primary IDE channel is:
/dev/ide/host0/bus0/target0/lun0
An my root partition on this disk is:
/dev/ide/host0/bus0/target0/lun0/p3

Regards.
