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.
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.
Ensure that the left navigation pane displays the Vservers hierarchy.
3.
In the navigation pane, select the Vserver and click SnapMirror.
4.
Select the SnapMirror relationship that you want to resynchronize.
5.
Click Operations > Resync.
6.
Select the confirmation check box and click Resync.
