ONTAP Recipes: Use MetroCluster switchback functionality after a switchover operation


Did you know...


You can use MetroCluster switchback functionality after a MetroCluster switchover operation?


NetApp MetroCluster provides synchronous replication for NetApp ONTAP customers and consists of an ONTAP cluster at each customer site. When a site goes down, the switchover functionality is used to move the customer workload to the remote site.


Use the MetroCluster switchback functionality after a MetroCluster switchover operation restores a workload to a remote disaster-stricken site:  

1. Verify that the disaster-stricken cluster meets the following requirements:

    a. Power and connectivity have been restored to switches, intersite links, and disk shelves.

    b. Nodes are rebooted (if necessary).

    c. Aggregates are resynchronized through the healing functionality: metrocluster heal-phase root and
        metrocluster heal-phase aggregates.

2. Invoke the MetroCluster switchback CLI.

3. Run the metrocluster operation show command to view the status of the switchback operation.
