Greetings, I am running a Micron (Pentium III Xeon processor) server with RedHat 9.0. It has hardware RAID (DAC960/Mylex RAID). 2 of the drives (1 and 2) in the array spontaneously went offline. So, I rolled to a contingency server and ran various diagnostics and found nothing wrong with the drives or the controller. All I had to do was go into advanced options and make them online to restore the system drive. The system is up and I am monitoring it. Can anyone think of any reasons why something like this might occur? Thanks. Cherie.Matchan@xxxxxx, University of Cincinnati I've stopped 12,002 spam messages. You can too!
