3ware raid controller, unit unusable, several degraded disks

3waredegradedraidraid6

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 originally being a part of the array shows as #degraded"
The two disks that was synced in are ok and the las swapped disk is "spare".
With 2 of 5 degraded and one missing I can't rebuild.
Why are the two disks marked as degraded and whan, if anything, can I do to get them online again?
Both disks are ok according to SMART…

Please help.

Trash the RAID set, rebuild it from scratch and restore from backups.
