Your colleagues are correct about the RAID levels, you can only do RAID5
with a minimum of 3 disks.

Your available options with 2 disks are JBOD, RAID0 or RAID1.

You obviously want RAID1.

How have they tried to install the server ?

I've had no problems ever installing 8.2 or 8.3 as a RAID using either
gmirror, or hardware RAID.

Does the server have a hardware RAID controller or are you trying
software RAID ?

Do you have remote console access to the server ?
