You might need to upgrade the firmware on a MetroCluster IP switch.

When you install the switch software on each of the switch, you must first check the health of the configuration.

You must repeat this task on each of the switch in succession to ensure that all MetroCluster components are healthy.

Steps
  1. Check the health of the configuration.

    1. Check that the MetroCluster is configured and in normal mode on each cluster: metrocluster show

      cluster_A::> metrocluster show
      Cluster                   Entry Name          State
      ------------------------- ------------------- -----------
       Local: cluster_A         Configuration state configured
                                Mode                normal
                                AUSO Failure Domain auso-on-cluster-disaster
      Remote: cluster_B         Configuration state configured
                                Mode                normal
                                AUSO Failure Domain auso-on-cluster-disaster
    2. Check that mirroring is enabled on each node: metrocluster node show

      cluster_A::> metrocluster node show
      DR                           Configuration  DR
      Group Cluster Node           State          Mirroring Mode
      ----- ------- -------------- -------------- --------- --------------------
      1     cluster_A
                    node_A_1       configured     enabled   normal
            cluster_B
                    node_B_1       configured     enabled   normal
      2 entries were displayed.
    3. Check that the MetroCluster components are healthy: metrocluster check run

      cluster_A::> metrocluster check run
      
      Last Checked On: 10/1/2014 16:03:37
      
      Component           Result
      ------------------- ---------
      nodes               ok
      lifs                ok
      config-replication  ok
      aggregates          ok
      4 entries were displayed.
      
      Command completed. Use the "metrocluster check show -instance" command or sub-commands in "metrocluster check" directory for detailed results.
      To check if the nodes are ready to do a switchover or switchback operation, run "metrocluster switchover -simulate" or "metrocluster switchback -simulate", respectively.
    4. Check that there are no health alerts: system health alert show

  2. Install the software on the first switch.

    Follow the steps for installing switch software in the relevant section in the MetroCluster IP Installation and Configuration Guide depending on whether the switch type is Cisco or Broadcom:

  3. Repeat the previous step for each of the switches.

  4. Repeat step 1 to check the health of the configuration.
