Verifying the cluster configuration

Simulating a failover is an important part of configuration testing. After completing the configuration, verify that failover occurs as desired.

To verify the configuration of a cluster, either move the online groups, or shut down an active cluster node, as follows:

  • Use Veritas Cluster Manager (Java Console) to switch all the service groups from one node to another.

  • Simulate a local cluster failover by shutting down an active cluster node.

To switch service groups

  1. In the Veritas Cluster Manager (Java Console), click the cluster in the configuration tree, click the Service Groups tab, and right-click the service group icon in the view panel.

    • Click Switch To, and click the appropriate node from the menu.

    • In the dialog box, click Yes. The service group you selected is taken offline on the original node and brought online on the node you selected.

    If there is more than one service group, you must repeat this step until all the service groups are switched.

  2. Verify that the service group is online on the node that you selected to switch to in the first step.
  3. To move all the resources back to the original node, repeat the first step of this procedure for each of the service groups.

To shut down an active cluster node

  1. Gracefully shut down or restart the cluster node where the service group is online.
  2. In the Veritas Cluster Manager (Java Console) on another node, connect to the cluster.
  3. Verify that the service group has failed over successfully, and is online on the next node in the system list.
  4. If you need to move all the service groups back to the original node, perform these steps sequentially:

    • Restart the node that you shut down in the first step.

    • Click Switch To, and click the appropriate node from the menu.

    • In the dialog box, click Yes.

      The service group you selected is taken offline and brought online on the node that you selected.
