The successor is now developed as part of the community.sap_install collection.
This role configures pacemaker for an existing SAP HANA System Replication deployment on a 8.x systems.
This role is intended to use on RHEL systems where SAP HANA has been deployed and HANA System Replication is configured between the 2 RHEL Nodes. The following Ansible Roles can be used to get to this desired state:
It needs access to the software repositories required to deploy RHEL High Availability (see also: Automated SAP HANA System Replication in Scale-Up in pacemaker cluster)
You can use the redhat_sap.sap_rhsm Galaxy Role to automate this process
