I recently had a problem with my SAS card being dislodged slightly causing all sorts of disk errors, i quickly stopped the array however it disabled disk 6. Now when i boot back up disk 6 is still disabled.

 

How can i get it working again? i can do a SMART check on the disk and it all looks fine to me. Is there some procedure i need to follow to enable the disk?
