Perform the switchback operation to return the MetroCluster configuration to normal operation. The nodes on site_A are still awaiting upgrade.

Site_A awaiting upgrade after MetroCluster switchback
Steps

  1. Issue the metrocluster node show command on site_B and check the output.

    1. Verify that the new nodes are represented correctly.

    2. Verify that the new nodes are in "Waiting for switchback state."

  2. Perform the healing and switchback by running the required commands from any node in the active cluster (the cluster that is not undergoing upgrade).

    1. Heal the data aggregates:
      metrocluster heal aggregates

    2. Heal the root aggregates:

      metrocluster heal root

    3. Switchback the cluster:

      metrocluster switchback

  3. Check the progress of the switchback operation:

    metrocluster show

    The switchback operation is still in progress when the output displays waiting-for-switchback:

    cluster_B::> metrocluster show
Cluster                   Entry Name          State
------------------------- ------------------- -----------
 Local: cluster_B         Configuration state configured
                          Mode                switchover
                          AUSO Failure Domain -
Remote: cluster_A         Configuration state configured
                          Mode                waiting-for-switchback
                          AUSO Failure Domain -

    The switchback operation is complete when the output displays normal:

    cluster_B::> metrocluster show
Cluster                   Entry Name          State
------------------------- ------------------- -----------
 Local: cluster_B         Configuration state configured
                          Mode                normal
                          AUSO Failure Domain -
Remote: cluster_A         Configuration state configured
                          Mode                normal
                          AUSO Failure Domain -

    If a switchback takes a long time to finish, you can check on the status of in-progress baselines by using the metrocluster config-replication resync-status show command. This command is at the advanced privilege level.

What's next?

Complete the upgrade.
