Beginning with Tiebreaker 1.7, you can simulate a switchover to test the MetroCluster Tiebreaker switchover functionality.

About this task

  • The monitor switchover-simulate command is only supported in Tiebreaker 1.7 or later.

Steps

  1. Check the Tiebreaker monitoring status: monitor show -status

    Example 
    NetApp MetroCluster Tiebreaker :> monitor show -status
MetroCluster: A700
    Disaster: false
    Monitor State: Normal
    Observer Mode: false
    Silent Period: 5
    Override Vetoes: false
    Cluster: ClusterA_siteA(UUID:713e5ab2-b4e8-11f0-91aa-00a098ef36a2)
        Reachable: true
        Intersite Connectivity Available: true
            Node: node_A1(UUID:9f6cecbf-b4e4-11f0-9d0f-00a098ef36a2)
                Reachable: true
                Intersite Connectivity Available: true
                State: normal
            Node: node_A2(UUID:2719bb56-b4e7-11f0-996c-00a09897caa3)
                Reachable: true
                Intersite Connectivity Available: true
                State: normal
    Cluster: ClusterB_siteB(UUID:72839591-b4e8-11f0-b688-00a09897cb73)
        Reachable: true
        Intersite Connectivity Available: true
            Node: node_B1(UUID:abfeab89-b4e4-11f0-a077-00a09897cb73)
                Reachable: true
                Intersite Connectivity Available: true
                State: normal
            Node: node_B2(UUID:31e395bf-b4e7-11f0-bf99-00a09897cb2f)
                Reachable: true
                Intersite Connectivity Available: true
                State: normal

  2. Perform a switchover simulation:

    monitor switchover-simulate -monitor-name <monitor_name> -cluster <cluster_name>

    The command returns the following output for a successful operation:

    Successfully triggered Switchover Simulation. Please check the status of the Switchover Simulation on the ONTAP cluster using command "metrocluster operation history show"
