Verifying negotiated switchover

You can test the negotiated (planned) switchover operation to confirm uninterrupted data availability.

About this task

This test validates that data availability is not affected (except for Microsoft Server Message Block (SMB) and Solaris Fibre Channel protocols) by switching the cluster over to the second data center.

This test should take about 30 minutes.

This procedure has the following expected results:

For MetroCluster IP configurations:

Procedure

  1. Confirm that all nodes are in the configured state and normal mode: metrocluster node show
    cluster_A::>  metrocluster node show
    
    Cluster                        Configuration State    Mode
    ------------------------------ ---------------------- ------------------------
     Local: cluster_A               configured             normal
    Remote: cluster_B               configured             normal
    
    
  2. Begin the switchover operation: metrocluster switchover
    cluster_A::> metrocluster switchover
    Warning: negotiated switchover is about to start. It will stop all the data Vservers on cluster "cluster_B" and 
    automatically re-start them on cluster "cluster_A". It will finally gracefully shutdown cluster "cluster_B".
    
  3. Confirm that the local cluster is in the configured state and switchover mode: metrocluster node show
    cluster_A::>  metrocluster node show
    
    Cluster                        Configuration State    Mode
    ------------------------------ ---------------------- ------------------------
    Local: cluster_A                configured             switchover
    Remote: cluster_B               not-reachable          -
                  configured             normal
    
    
  4. Confirm that the switchover operation was successful: metrocluster operation show
    cluster_A::>  metrocluster operation show
    
    cluster_A::> metrocluster operation show
      Operation: switchover
          State: successful
     Start Time: 2/6/2016 13:28:50
       End Time: 2/6/2016 13:29:41
         Errors: -
    
    
  5. Use the vserver show and network interface show commands to verify that DR SVMs and LIFs have come online.
