ProcedureHow to Verify the Failover DAS Component

The DAS resource group was created in How to Configure and Activate Network Resources.

Perform this procedure on all of the potential primary nodes or zones of the DAS component. This procedure requires a pair of nodes, indicated as Node1 and Node2.

  1. On a cluster member, Node1, become superuser or assume a role that provides solaris.cluster.admin RBAC authorization.

  2. Bring the DAS resource group online on Node1.


    # clresourcegroup online -n Node1 DAS-resource-group

  3. Connect to the administrative console from a web browser.


    https://IP-address:port

  4. Verify that you are connected to the administrative console.

  5. Switch the resource group from Node1 to Node2.


    # clresourcegroup online -n Node2 DAS-resource-group

  6. Connect to the administrative console from a web browser.


    https://IP-address:port

  7. Verify that you are connected to the administrative console.

    If you are not able to connect to the administrative console from the browser, perform the following actions.

  8. Test high availability by killing the DAS process manually.

    The DAS fault monitor detects the unavailability of the process and restarts it locally.

  9. Test data service functionality by forcing DAS failover.

    Note the values of the standard resource properties Retry_count and Retry_interval. Kill the DAS process manually a number of times equal to Retry_count and within the time period Retry_interval. The DAS resource fails over to another cluster member.

  10. Verify the DAS failover.

    If the DAS resource has not failed over, perform the following actions.
