I have an older server with a Adaptec 2120S RAID controller, configuration is (was) RAID 5 with 4 drives and a single hot-spare drive.
This morning it was showing two failed drives and is now running on 3 drives. We replaced the two failed drives, initialized them and set them as dedicated hot-spare drives. My problem is it will not rebuild the array and it still shows degraded. I have tried removing the hot-spare assignment and reapplying it and it still will not enter the rebuild state.
Any advice would be appreciated as we need to get 6 more months out of this server before replacement.
Thanks for your help.
