Verifying the health of the MetroCluster configuration

You must verify the health and connectivity of the MetroCluster configuration prior to performing the upgrade.

Procedure

  1. Verify the operation of the MetroCluster configuration in ONTAP:
    1. Check whether the nodes are multipathed: node run -node node-name sysconfig -a
      You should issue this command for each node in the MetroCluster configuration.
    2. Verify that there are no broken disks in the configuration: storage disk show -broken
      You should issue this command on each node in the MetroCluster configuration.
    3. Check for any health alerts: system health alert show
      You should issue this command on each cluster.
    4. Verify the licenses on the clusters: system license show
      You should issue this command on each cluster.
    5. Verify the devices connected to the nodes: network device-discovery show
      You should issue this command on each cluster.
    6. Verify that the timezone and time is set correctly on both sites: cluster date show
      You should issue this command on each cluster. You can use the cluster date commands to configure the time and timezone.
  2. Check for any health alerts on the switches (if present): storage switch show
    You should issue this command on each cluster.
  3. Confirm the operational mode of the MetroCluster configuration and perform a MetroCluster check.
    1. Confirm the MetroCluster configuration and that the operational mode is normal: metrocluster show
    2. Confirm that all expected nodes are shown: metrocluster node show
    3. Issue the following command: metrocluster check run
    4. Display the results of the MetroCluster check: metrocluster check show
  4. Check the MetroCluster cabling with the Config Advisor tool.
    1. Download and run Config Advisor.
    2. After running Config Advisor, review the tool's output and follow the recommendations in the output to address any issues discovered.
