Canonier, The controller is showing one of the drives in Foreign. What you need to do is hit CTRL-P from the screen you showed, back to the main page. Then hit F2 and then select Foreign Config. From that menu select to CLEAR FOREIGN CONFIG. After that the drive should rejoin the existing array.
Hi! We have 4 PowerEdge 1950 servers. Two of these servers have a problem with RAID. RAID is PERC 5/i  and two SAS disks. It shows, there is only one disk in RAID BIOS instead two. Disks works! Its are new, SAS 300 Gb. I see green lights on its. I cannot create disk volume. I tried install another disks and interchange disks. Also I tried update RAID bios. Problem reminds. Please, what is possible to do else?
