You have a customer with a CLARiiON CX4. They have a RAID 6 volume that holds image files, which is approaching 95% capacity. They wish to expand the LUN using metaLUN technology. 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.
What can the customer do to expand the LUN?

A.
Nothing. RAID 6 LUNs cannot be expanded.

B.
Back up the data, destroy the RAID 6 LUN, create it as a RAID 1/0 LUN, and then grow the size of the LUN.

C.
Purchase additional drives to create a RAID 6 group, create LUNs in the group, and then grow the LUN.

D.
UseSnapView to clone the LUN to a larger RAID 1/0 LUN.
