However, they only have RAID 1/0 LUNs available in the array at this time. They tried expanding using the available LUNs, but Navisphere would not allow the action to be performed. There are no unbound drives in the array. The array is available to applications 24×7, and no downtime can be taken at this time on the array or the RAID 6 LUN.
