Switching online nodes
Failover simulation is an important part of configuration testing. Test the failover by switching online nodes.
The RVG service group is online in both the primary and secondary zone. However, within a zone, if more than node is configured, the RVG service group should fail over with the application service group.
Note:
This should never be tested on systems with live data. A reliable and tested backup should be available. A tested backup means that it has been tested successfully by a restore.
Switch the application service group between nodes using Veritas Cluster Manager (Java Console). When you complete the procedure, you will see the online system role shift from one system to another.
If you enter the system name manually from the Java Console, specify the name in upper case.
To switch online nodes
- In the Veritas Cluster Manager (Java Console), click the cluster in the configuration tree, and click the Service Groups tab.
- Switch the service group as follows:
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.
- Verify that the service group is online on the node you selected.
- To move all the resources back to the original node, repeat step 2 for each of the service groups.
