I am installing Unity v4.2 on a 7825H3 server using the Platform Configuration DVD. The problem is that the utility displays a message saying that the SATA RAID has to be configured and a reboot is required. However, the RAID 1 is not created.
I then continued with the install and built the RAID 1 from the BIOS.
I decided to give the install another try and found out that RAID set was actually blown away by the Platform Configuration utility.
