I have just commenced a POC utilizing Cluster Aware Updating to patch a Fail-over Cluster.
The patching process operates as required but I have noted that the nodes are not placed in Maintenance Mode within SCOM 2012 SP1 and VMM 2012 SP1.
When the node is rebooted as part of the patch installation, SCOM generates a heartbeat failiure alert as it does not see the node as under maintenance.
Please can you confirm if there is integration between CAU and SCOM/VMM and if so, why it is not operating as required.
