How to Verify the Installation and Configuration of Sun Cluster HA for SAP for Failover Application Server

To verify the Sun Cluster HA for SAP installation and configuration for a failover application server, perform the following steps.

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

2. As user sapsidadm, start the SAP GUI to check that the application server is functioning correctly.

3. Use the application server stopsap script to shut down the SAP application server on the node you identified in Step 1.

   The Sun Cluster software restarts the application server.

4. As user root, switch the resource group that contains the SAP application server resource to another cluster member.

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

5. Verify that the SAP application server starts on the node you identified in Step 4.

6. Repeat Step 1 through Step 5 until you have tested all of the potential nodes on which the SAP application server can run.
