mk-ansible-roles.saphana-hsr

saphana-deploy

THIS ROLE IS DEPRECATED AND WILL BE DELETED IN 12.2022
use community.sap_install collection instead

This adds HANA System Replication (HSR) to previously deployed SAP HANA 1.0 SPS 12 and above (HANA2) systems.

Requirements

This role requires the system to be prepared with saphana-preconfigure and deployed with saphana-deploy role.

Role Variables

Configuration for Instance deployment

This role uses the same variables as the saphana-preconfigure and saphana-deploy role. It introduces the following additional variables:

hsr_deploy_type: This has to be set enable on the primary and register on the secondary node.
hsr: this is a dictionary that defines the parameters for enabling system replication. See example below

These variables need to be set in the host_vars file. See Best Practises for more details.
