Active-Active controllers in 2240-4


I have a question about the 2240-4 with a drive shelf attached. If i have two controllers in an active active mode. Does each controller have to have a raid set on each disk shelf. Or can i have one controller control the internal disk and one control the attached shelf. I am wondering do i have to split the drives in each shelf to get HA with the controllers. If i have to split the drives do I lose 3 drives to each raid set with raid6DP and one hot spare per raid set.



Every disk can be assigned to any controller in HA pair. They must not be allocated in units of whole shelves.
