LUN Clone Split Restore method

SnapDrive uses the LUN Clone Split Restore method for Data ONTAP 7.1 or later. This feature enables you to perform a restore operation quickly, because the only data blocks that are duplicated during the restore operation are those currently in use in the active file system.

Note: The restore destination must exist in the active file system.

SnapManager follows these steps to restore a LUN to its LUN clone that exists in the active file system:

SnapManager creates a LUN clone.
The LUN clone is unavailable for data I/O. The LUN clone inherits the presentation of the LUN in the active file system.
SnapManager renames the LUN clone with the name of the original clone.
LUN Clone Split (LCS) starts in the background.
The LUN becomes available for data I/O after LCS completes.

Verifying the LUN Clone Split status
You can determine the LUN Clone Split status of your LUNs during a restore operation using the storage system console or SnapDrive.
