RN316+EDA500: Global Hot Spare possible?

Is the following possible? RN316 with 6 disks, 5 used as RAID5 for volume1, 6th as global hot spare; attached EDA500 with 5 disks used as RAID5 for volume2; all disks have same size of 4 TB. After detection of a disk failure, the hot spare disk should replace the defect disk either in volume1 or in volume2. This should happen automatically, without any user interaction. Then, after replacement of the defect disk, either in the RN316 or in the EDA500, this new disk should become the global hot spare with the same capabilities. Thanks.

Current 6.1.2 code does what you want. As long as there is a free disk in each chassis (Host or EDA500) in Flex-RAID mode, failure disk will get recover with free disk. Note that free disk need to be in same chassis.
