in FAS 2240-2 all disks are assigned to single controller partner controller is not getting up due to no spare disk.
i need help to remove some disk from first controller and want to make partner controller active.
The only way to remove disk from aggregate is to convert RAID_DP to RAID4, thus freeing one parity disk per raid group.
any way in command line like unown or unassign the disk.i am not sure
If the controller is in production there is no option. If not we can restructure it.
