Resynchronizing SnapMirror relationships
You can use the SnapMirror window to reestablish a SnapMirror relationship that was broken. You can perform a resynchronization operation to recover from a disaster that disabled the source volume or qtree.
About this task 
When you perform a resynchronization operation, the contents on the SnapMirror destination are overwritten by the contents on the source. The resynchronization operation can cause loss of data written to the destination volume after the base Snapshot copy was created.
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 resynchronize.
4.
Click Operations > Resync.
5.
Select the confirmation check box and click Resync.
