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 is converted to a copy of the original destination volume.
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 page, double-click the appropriate storage system.
2.
Expand the Storage Virtual Machines hierarchy in the left navigation pane.
3.
In the navigation pane, select the Storage Virtual Machine (SVM) and click SnapMirror.
4.
Select the SnapMirror relationship that you want to reverse resynchronize.
5.
Click Operations > Reverse Resync.
6.
Select the confirmation check box and click Reverse Resync.
