Upgrading firmware on MetroCluster IP switches


  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
                    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:
    • Downloading and installing the Cisco switch NX-OS software
    • Downloading and installing the Broadcom switch EFOS software

    MetroCluster IP installation and configuration

    Repeat this step for each of the switches.

    Note: In the sections referenced, skip the step on downloading the reference configuration (RCF) files.
  3. Repeat step 1 to check the health of the configuration.
