My Dell Poweredge R720 uses the PERC H710P Mini BIOS config utility 4.03-0002 and has been running RHEL 6 on a RAID1 array (Made up of 2 3TB WD SAS HDs). I installed 2 more SATA drives today as a separate RAID1 array (With the intent of using dd to clone my older drivers to these new drives), and now RHEL6 on my original RAID array won't boot. In the RAID utility, they show up as unconfigured physical disks, and my new ones show up as the new virtual disk 0. I couldn't see anywhere to tell the utility that I still need my old drives to be the primary virtual disk/boot device... Thanks in advance for your time.
