I backup my server using acronis True Imager Server 9.1 using the backup all files and partions option. Created a boot cd then installed backup hard drives 3 in Raid 5 Configuration in Dell Poweredge Server. Restore looked like all was well except it appeared that it was restoring C>D and D>E I guest this meant it was changing my drive letters? Got a successful restore message and tried to boot but it did not boot? The Raid controller did not recognize the drives at boot sequence. Put my 3 original drives in and back up and running. This is for my disaster recovery plan fast restore to 3 new drives. Is there anything special that needs to be done to get the new drives to boot and be recognized by the Raid Controller?
