Boot loader problem after addiing SCSI disk

[Chiu, PCM (Peter)]

Thanks for your response, Arun,

Unfortunately the three scsi devices are not identical.

The old sda and sdb are two internal raided file systems on two 3ware 8
port PATA controllers,
and the new one is an external raid brick fed through a USCSI 160
controller.

I cannot make any physical change on the scsi devices.

As per new configuration replace the sda disk with sdb , sdb with sdc
and sdc with sda. Keep ur grub and mbr in old configuration. 
   This might work.

  I have hit a problem in booting up a RH 9 box after adding a SCSI
disk.

The boot process pauses after displaying:

GRUB Loading stage 1.5
GRUB Loading, please wait...

The machine does not show any response, not even
Control-Alternate-Delete.

I boot off RH9 CD and started off Linux rescue mode.

I can see all the existing scsi disks as well as the new one - though
somehow, the new one becomes sda, and the old sda becomes sdb, and the
old sdb becomes sdc.

I tried to reset the MBR with grub-install /dev/sdb but same result.

I have also tried replacing all references on hd0,0 to be hd1,0 in
grub.conf, and reapply grub-install /dev/sdb, still no joy.

Any idea anyone?

Thanks.

Peter
