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. For Infinite Volumes, the resynchronization operation recovers the volume and its constituents.
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.
- For Infinite Volumes with storage classes, if new constituents have been added to the source Infinite Volume since the mirror relationship was created, you cannot use System Manager to resynchronize the mirror relationship.
Instead, you should use OnCommand Workflow Automation.
Steps
- Click .
- Select the mirror relationship that you want to resynchronize.
- Click
