Creating a LUN Clone
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.
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.
To create a LUN clone of a logical drive:
1. Click the Storage tab.
2. Click the Logical Drive icon.
The Logical Drive list appears.
3. Click the logical drive you want, then click the LUN Clone button.
4. Make settings as required:
Note
When you add physical drives to a RAID 10 array, it becomes a
RAID 1E array by default.
If you are adding an even number of physical drives to a RAID 10
array and you want the target array to be RAID 10, you must
specify RAID 10 under RAID level.
Important
The action of creating a LUN momentarily takes the original LUN
or logical drive offline, meaning nobody can read or write to it.
