Resynchronizing mirror relationships

You can reestablish a mirror relationship that was broken earlier. You can perform a resynchronization operation to recover from a disaster that disabled the source volume.

Before you begin

The source and destination clusters and the source and destination storage virtual machines (SVMs) must be in peer relationships.

About this task

When you perform a resynchronization operation, the contents on the mirror destination are overwritten by the contents on the source.
Attention: The resynchronization operation can cause loss of newer data written to the destination volume after the base Snapshot copy was created.
If the Last Transfer Error field in the Protection window recommends a resynchronization operation, you must first break the relationship and then perform the resynchronization operation.

Procedure

Click Protection > Relationships.
Select the mirror relationship that you want to resynchronize.
Click Operations > Resync .
Select the confirmation check box and click Resync.
