Michael, we had a similar issue with one of our PowerEdge 4400 servers a few months ago, following a reboot the system would not boot and the PERC controller could not find the Raid array. When we checked in the BIOS (NOT the onboard Raid setup tools!) some of the settings in there had reverted to default (cannot remember off the top of my head which ones). However, when they were set correctly and rebooted the machine came up fine !!!!

They then powered it back up and got a message that all RAID configuration had been lost. They can reconfigure but it asks to format the drives. Is there anyway to recover what is on the disks that anyone might be aware of? _________________________________ Michael Boggan Network Engineer/Citrix Admin Virtual Desktop Inc.
