I have a server which was freezing up frequently. I determined that the Raid controler was going bad.
The Raid controller that was in the server is an Adaptec SCSI RAID 2120S. There are 5 hard drives in the server setup in 1 Raid 5 array.
I looked for a replacement controller, and got pretty desperate. Found a HP Smart Array 6402 laying around. Decided it should not harm anything to plop that in place of the 2120 to see if the array would show.
The array did show as a raid 5 array, but I can not see any drive letters.
After playing with it for a while, figured I would put the old controller back in and now the Drive letters are not coming back, but the array is still detecting as "raid 5 optimal"
Anyone know if the data is wipped out now that they were hooked up to the 6400? I am ordering a new 2120 and hoping the controller just died.
