Just last month I did this on a dell poweredge 2600. It was a fiasco, but it
worked.
My intention was to use Acronis True Image to copy an image of the original
drive onto the new SCSI array.
Customer bought the PERC upgrade and 4 more 36 Gb drives. The problem was
that in the bios, the system was either a standard scsi controller, or a
raid controller - not both because it had only a single hot-swap backplane.
So with SBS2K3 running on the single SCSI drive, it would not let me install
the raid drivers because the RAID was not present. I tried everything I
could, but it wouldn't work. When the perc Raid controller was enabled and
setup so that the array would not wipe the existing data, windows would blue
screen because it could not recognize the drive as a raid array. Catch-22!
If the RAID controller was a PCI-X card, then it would be easy to just pop
in the card and let Windows find it. Then setup the array and copy the drive
image.
What I did was:
1) Temporarily install a Promise IDE controller and 120Gb IDE hard drive.
2) Boot Windows and let it add the IDE card and drivers to it's
configuration.
3) Acronis "clone" image of SCSI drive over to IDE drive.
4) Remove SCSI drive and boot system from IDE drive. - This worked. Now
system is running from an IDE drive.
5) Shutdown. Added SCSI drives and configured array in Bios. (Also keeping
Bios to boot from IDE)
6) Boot Windows and let it find and install the RAID controller.
7) Acronis "Clone" image of IDE drive to SCSI array.
8) Remove IDE components and boot from new SCSI array.
It took me over 10 hours to pull this off... Now that I know how to do it,
it could be done a lot faster.
