IBM ServerRAID problems with single disk

Hello Experts,

What would seem simple has me perplexed, I must be missing something...

I have a IBM x3250 server with an LSI Logic RAID controller. Normally this server has 2 disks and is setup in RAID 1 and works fine. We need to do a quick build a up a new server just for testing in our lab, so we popped the 2 existing disks out and just replaced it with a single disk. We don't need any redundancy for this test and it's only a week or two long.

For some reason the LSI Config utility will not let me configure a RAID 0 array, or any kind of single disk setup. The problem is when I get to Windows 2003 installer and load my RAID controller driver no disks are found and the install can't continue. My guess is it's becuase there is no RAID array initialised.

The controller can see the single 500GB disk(and the Windows install can see the controller)but won't let me apply any RAID configs to it, my options are from the LSI Config

Create IM Volume : 2 Mirrored disks
Create IME Volume : Mirrored & Enhanced 3-8 disks
Create IS Volume : Striping over 2-8 disks

Has anyone come across this before, and how do I force this server to work with just a single disk? It would seem crazy that I have to use two disks, but...

Thanks.

Also just to add to this I'm trying to use a 500GB WD drive.

Build the server using RAID1, and once finished, just remove the 2nd HD. Your system should still run. At least setup the array in RAID 1. After that you should also be able to install the OS with the array "broken".
