Most likely the NVRAM version got corrupted. Tht situation is opposite. Controller "remember" the configuration, but on disks there is no RAID config (they are all just in READY state). And in this case controller do not "want" to use config from NVRAM.

Good luck, I will keep my fingers crossed for you. I had similar > experience with Mylex card on live server, it wasn't fun at all. Thanks, i'll try to, but i'm not sure how this drives were configured. First of all it was done not by me. Then 2 drives vere changed because of disks falure and Hot spare disks were used, so which drive was in what RAID is unknown. So i hope there is some port or utility to view the data on each hard drive to determine what part of which RAID it was.
