If you got your root partition on an IDE disk or connected to another
SCSI Hostadapter (SHA) you can load your SCSI driver as a module. Unload
your driver (go to single user mode (telinit S), unmount all SCSI
partitions connected to your SHA, unload the SHA driver (rmmod) and
the SCSI modules.) and reload all. Now remount everything and return
to multiuser mode (telinit 2).
Beware that the assignment of sda/b/c/d etc. can change when there is a
new SCSI device with a SCSI ID smaller than the last one before
installing it.).
There might be another solution, I just don't know about. If the ID is
larger than the one of the last mounted device, it should be possible (in
priciple) to get the SCSI bus resetted and the new device to be
discovered. I don't know, if the hogher level SCSI drivers (sg,sd,sr ...)
will get knowledge of the new device this way.
