Unfortunately we got a couple of Dell servers (PowerEdge 1850). One drive from the backup system was used to rebuild a "live" system. Now the backup machine needs to be rebuilt from the drive used on the live system. It uses PERC/CERC BIOS utility U821 from 2004. The steps were: the original drive 0 remained in the backup system and drive 1 was used to rebuild the "live" system. Then they upgraded the live system and then used a new drive to replace the backup drive. This leaves the original backup drive 0 out of date. My question now is which steps do I take to rebuild the backup system from drive 1 and thus make drive 0 a copy of drive 1. -- Bobby
