How to Verify the Sun Cluster HA for SAP Installation With Central Instance

Perform the following steps to verify both the Sun Cluster HA for SAP installation with a central instance and the Sun Cluster HA for DBMS installation and configuration.

1. Log in to the node that hosts the resource group that contains the SAP central instance resource.

2. Become user sapsidadm.

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

4. Use the central instance stopsap script to shut down the SAP central instance.

   The Sun Cluster software should restart the central instance because the Sun Cluster software controls the SAP software.

5. Run the scswitch command to switch the SAP resource group to another cluster member.

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

6. Verify that the SAP central instance starts on this node.

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