Switching online nodes

An important part of configuration testing is simulating a failover. Test the failover by switching the application service group between 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

  1. Open the Veritas Cluster Manager (Java Console).

    Click Start > All Programs > Veritas > Veritas Cluster Server > Veritas Cluster Manager - Java Console).

    On Windows 2012 operating systems, use the Apps menu.

  2. Click Click here to log in for the appropriate cluster. If this is your first use of the Veritas Cluster Manager, click File > New Cluster. In the New Cluster - Connectivity Configuration window, enter the computer name in the Host name field and click OK.
  3. In the Machinename - Login window, enter your user name and password in the respective fields and click OK.
  4. In the left pane, right-click the service group, and select an alternate system name from the Switch To entry.
  5. In the Question dialog box, click Yes to confirm that you want to switch the service group to the other node.
