Reverse resynchronizing SnapMirror relationships
You can use the SnapMirror window to reestablish a SnapMirror relationship that was broken. In a reverse resynchronization operation, you reverse the functions of the source and destination and the source volume or qtree is converted to a copy of the original destination volume or qtree.
About this task 
When you perform reverse resynchronization, the contents on the SnapMirror source are overwritten by the contents on the destination. This operation can cause data loss on the source.
Steps 
1.
From the Home tab, double-click the appropriate storage system.
2.
In the navigation pane, click SnapMirror.
3.
Select the SnapMirror relationship that you want to reverse resynchronize.
4.
Click Operations > Reverse Resync.
5.
Select the confirmation check box and click Reverse Resync.
