After upgrading the controller modules, perform the necessary tasks to complete the controller upgrade.

Check the health of the MetroCluster configuration

After upgrading the controller modules you must verify the health of the MetroCluster configuration.

About this task

You can perform this task on any node in the MetroCluster configuration.

Steps

  1. Verify the operation of the MetroCluster configuration:

    1. Confirm the MetroCluster configuration and that the operational mode is normal:
      metrocluster show

    2. Perform a MetroCluster check:
      metrocluster check run

    3. Display the results of the MetroCluster check:

      metrocluster check show

  2. Verify the MetroCluster connectivity and status.

    1. Check the MetroCluster IP connections:

      storage iscsi-initiator show

    2. Check that the nodes are operating:

      metrocluster node show

    3. Check that the MetroCluster IP interfaces are up:

      metrocluster configuration-settings interface show

    4. Check that local failover is enabled:

      storage failover show

Upgrade the nodes on cluster_A

You must repeat the upgrade tasks to upgrade the nodes on cluster_A at site A.

Steps

  1. Repeat the steps to upgrade the nodes on cluster_A, beginning with Prepare for the upgrade.

    As you perform the tasks, all example references to the clusters and nodes are reversed. For example, when the example is given to switchover from cluster_A, you will switchover from cluster_B.

Restore Tiebreaker or Mediator monitoring

After completing the upgrade of the MetroCluster configuration, you can resume monitoring with the Tiebreaker or Mediator utility.

Steps

  1. Restore monitoring if necessary, using the procedure for your configuration.

    If you are using…​ Use this procedure

    Tiebreaker

    Add MetroCluster configurations.

    Mediator

    Configure the ONTAP Mediator service from a MetroCluster IP configuration.

    Third-party applications

    Refer to the product documentation.

Send a custom AutoSupport message after maintenance

After completing the upgrade, you should send an AutoSupport message indicating the end of maintenance, so automatic case creation can resume.

Steps

  1. To resume automatic support case generation, send an Autosupport message to indicate that the maintenance is complete.

    1. Issue the following command:
      system node autosupport invoke -node * -type all -message MAINT=end

    2. Repeat the command on the partner cluster.

Configure end-to-end encryption

If it is supported on your system, you can encrypt back-end traffic, such as NVlog and storage replication data, between the MetroCluster IP sites. Refer to Configure end-to-end encryption for more information.
