Unless your server supports UEFI it will probably not boot from a GPT partitioned disk. RAID controllers usually support splitting off a part of the array as a boot disk. I recently did this with an old server with a 3ware controller and 3TB disks. I created a RAID-10 and then in the advanced settings I told it to use 50G as a boot disk. The result was that I got a 50G /dev/sda which I could partition with a DOS label and 2.95T /dev/sdb which I let anaconda put a GPT label on. Anyway if you are using a BIOS instead of UEFI you need to provide a disk with a DOS partition label to boot from. Regards, Dennis
