A LUN clone is an exact copy of the original LUN or logical drive, including all the data it contains, at one point
in time. Use a LUN clone as a backup or to migrate a LUN from one system to another.
Important
The action of creating a LUN momentarily takes the original LUN or logical drive offline,
meaning nobody can read or write to it.
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
Super User
or
Power User
privileges.

1. From the Main Menu, highlight
