Red Hat Summit5.2. Updating the SAP HANA instances
If the SAP HANA System Replication setup is managed using the HA cluster configuration described in this document, some additional steps are needed in addition to the actual process of updating the SAP HANA instances before and after the update. Execute the following steps:
Put the SAPHana resource in unmanaged mode.
[root]# pcs resource unmanage SAPHana_RH1_02-clone- Update the SAP HANA instances using the procedure provided by SAP.
When the update of the SAP HANA instances has been completed and it has been verified that SAP HANA System Replication is working again, the status of the SAPHana resource needs to be refreshed to make sure the cluster is aware of the current state of the SAP HANA System Replication setup.
[root]# pcs resource refresh SAPHana_RH1_02-cloneWhen the HA cluster has correctly picked up the current status of the SAP HANA System Replication setup, put the SAPHana resource back into managed mode so that the HA cluster will be able to react to any issues in the SAP HANA System Replication setup again.
[root]# pcs resource manage SAPHana_RH1_02-clone
