A LUN clone has the same capacity, stripe size, read and write policies as the orignal LUN. However, the LUN
clone can be a different RAID level. The choice of RAID levels depends on the disk array. And if you have multiple
disk arrays, you can create the LUN clone on a different disk array than the original LUN.
This action requires
