Chapter 8. Optional - Enable SAP HA interface for Management of Cluster-controlled ASCS/ERS instances using SAP Management Tools

When a system admin controls a SAP instance that is running inside the Pacemaker cluster, either manually or using tools such as SAP Management Console (MC/MMC), the change needs to be done through the HA interface that’s provided by the HA cluster software. SAP Start Service sapstartsrv controls the SAP instances and needs to be configured to communicate with the pacemaker cluster software through the HA interface.

Please follow the kbase article to configure the HAlib: How to enable the SAP HA Interface for SAP ABAP application server instances managed by the RHEL HA Add-On?.
