How to Register and Configure Sun Cluster HA for SAP With Central Instance

To register and configure the Sun Cluster HA for SAP data service with a central instance, perform the following steps.

1. Become superuser on one of the nodes in the cluster that hosts the central instance.

2. Register the resource type for the SAP data service.

   For central instance, run the scrgadm command to register the resource type SUNW.sap_ci.

   # scrgadm -a -t SUNW.sap_ci

3. Run the scrgadm command to create SAP application resources in this failover resource group.

   # scrgadm -a -j sap-ci-resource -g sap-ci-resource-group -t SUNW.sap_ci -x SAPSID=SAPSID -x Ci_startup_script=ci-startup-script -x Ci_shutdown_script=ci-shutdown-script

4. Run the scswitch command to enable the resource group that now includes the SAP central-instance resource.

   # scswitch -Z -g sap-ci-resource-group
