Failure of the third node won't trigger any cluster action. The cluster detects the replication status of connected sites and the monitored attribute for the third site can change between `SOK` and `SFAIL` states. Any takeover tests to the third/DR site or executing your DR exercise process should first place the cluster resources into maintenance mode to prevent any undesired cluster action.

This important step optimizes the integration with the cluster and improves the detection when a cluster failover is needed. We highly recommend that you configure both SAPHanaSR and susChkSrv Python hooks. Follow the steps in [Implement the Python system replication hooks SAPHanaSR and susChkSrv](./sap-hana-high-availability.md#implement-hana-hooks-saphanasr-and-suschksrv).
