Reverting to old array

[D Nash]

I’ve got an HP ProLiant ML370 G4 with a SmartArray 6400 controller. It’s running Windows Server 2003.

The C: (system) drive is on one mirrored array.

The E: (data) drive is on a RAID 5 array.

I’ve installed three larger capacity hard disk drives for the E: drive. When I installed them I pressed F8 on the SmartArray BIOS and created a new Array. In Windows I then prepared and formatted the volume, then restored everything back from a backup. It worked fine, but I’ve got a problem with the restoration of the SQL master.mdf file which was on the E: drive.

Basically, I need to safely get the old data array installed back into the server, and I’d like to know how to do that. Is there a safe way to swap between the old and the new hard disks? The OS (C: drive) currently thinks drive E: is 580GB, whereas the old E: was only 72GB. I’m not sure I can simply plug in the old hard drives, and I’m worried in case I lose either one or both array configurations.

Thanks very much!
