1. You are using System Center Virtual Machine Manager 2008 (VMM) to manage a cluster resource. 2. One node of the cluster displays a status of Needs Attention. 3. Viewing the properties of the node displays a connection status of Not Responding on the status tab. 4. Remove and attempting to re-add the cluster back again fails with the following error:
Error (2912) An internal error has occurred trying to contact an agent on the node1.xxx server. (Unknown error (0x800007d0)) Recommended Action Ensure the agent is installed and running. Ensure the WS-Management service is installed and running, then restart the agent.
5. The other nodes can be added successfully, but when the cluster refreshes you receive the following message:
Warning (13926) Host cluster <name> was not fully refreshed because not all of the nodes could be contacted. Highly available storage and virtual network information reported for this cluster might be inaccurate. Recommended Action Ensure that all the nodes are online and do not have Not Responding status in Virtual Machine Manager. Then refresh the host cluster again.
This can occur if the Performance Counters on the node are corrupt.
