How to Verify the Sun Cluster HA for SAP Installation With Application Server

If you have installed and configured any SAP application servers, perform the following steps to verify the Sun Cluster HA for SAP installation and configuration with application servers.

1. Log in to the node that currently hosts the resource group that contains the SAP application-server resource.

2. Become user sapsidadm.

3. Start the SAP GUI to check that the Sun Cluster HA for SAP data service is functioning correctly.

4. Use the application-server stopsap script to shut down the SAP application server.

   The Sun Cluster software should restart the application server because the Sun Cluster software controls the SAP software.

5. Run the scswitch command to switch the resource group that contains the SAP application-server resource to another cluster member.

   # scswitch -z -h node2 -g sap-as-resource-group

6. Verify that the SAP application server starts on this node.

7. Repeat Step 1 through Step 6 until you have tested all potential nodes on which the SAP application server can run.
