3ware raid controller, unit unusable, several degraded disks

view story

http://serverfault.com – I was switching the disk drives in my server, running RAID 6 on 5 disks on a 3ware 9650SE controller, for newer disks and have run into a problem. The two first disks went fine, I took out one disk and inserted a new one, let the array rebuild and repeated for disk 2. When booting after switching the 3. disk I noticed two where wmissing, not just the one, so I did not ask the controller to rebuild, but shut it off and investigated. One of the remaining disks had a bad power connector, so I took out that disk and put in the one I had just taken out. When booting again booth of the disks origina (HowTos)
