If there is a need to update the nodes of a cluster one can do a rolling update.


On one node issue

    crm cluster stop
this will failover all relevant resources to the other node.

After this is done, any patching can proceed without consideration for SAP nor the Cluster on the node that got the cluster stopped.

Once the patching is done, maybe even a reboot, on the patched node the cluster is started again with

   crm cluster start
This will make the node available again for SAP Applications.

Care should be taken, that any SAP Application started correctly and is working properly. Especially any SAP Hana Secondary should be in

   Sync OK
status. It is necessary to check that the failover is available again.

After this the same process is repeated with the other node.

   crm cluster stop
patching, maybe reboot and then with

   crm cluster start

reintroduced into the cluster.
