Server Raid configuration

Hi Everyone,

I have come across a scenario that I wish to correct.
The server that I'm referring to is an IBM Xseries server with hot-swap scsi drives on a server raid backplane.
In the process of increasing drive capacity i have come across the follow issue.
The array are as follows:

Array 1: 2 mirrored drives
Array 2: 3 raid 5 drives

The system and operating system file reside on array 2.
If the server is configured as above and I restart the server it fails to find the boot disk.
This is obviously because the server is looking at array 1 to boot and array 1 is empty.

I want to change how the server boots so that it boots to array 2.
I can think of only 2 possible solution but I don't know if there is an easy way to achieve this:

1. change the array allocation so that the current array 2 becomes array 1.
2. Somehow tell the server to boot to array 2.

Any suggestions would be greatly appreciated
