Ah ... it is because you have multiple arrays across the same set of disks (called 'slicing'). You cannot reconfigure sliced arrays. You would have to do a backup/restore or delete the second VD to expand/reconfigure.
Hello, im trying to expand the existing Raid 6 storage. Ive added 4 new drives and they are listed as ready. However, in Volume there is no option to Reconfigure them. What am I missing? I read that only Raid 10, 50, 60 can not be expanded..
PERC H710P Mini Can not expand the storage
