THIS ROLE IS NO LONGER SUPPORTED

The new version is now part of the community.sap_install collection.

sap-hana-ha-pacemaker

This role sets up pacemaker for an existing SAP HANA System Replication on 8.x systems.

Requirements

This role is designed for RHEL systems where SAP HANA is installed and there are 2 RHEL nodes with HANA System Replication set up. You can use the following Ansible Roles to achieve this:

You will need access to the necessary software repositories for RHEL High Availability (for more details, see: Automated SAP HANA System Replication in Scale-Up in pacemaker cluster).

To automate this process, you can use the redhat_sap.sap_rhsm Galaxy Role.
