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.</P></BODY></HTML> Thu, 05 Jun 2025 06:31:45 GMT https://community.netapp.com/t5/ONTAP-Hardware/Active-Active-controllers-in-2240-4/m-p/48366#M3397 CGONZALES78 2025-06-05T06:31:45Z Re: Active-Active controllers in 2240-4 https://community.netapp.com/t5/ONTAP-Hardware/Active-Active-controllers-in-2240-4/m-p/48371#M3398 <HTML><HEAD></HEAD><BODY><P>Every disk can be assigned to any controller in HA pair.
