Cluster Network Connectivity
Applies To: Windows Server 2008 R2
A failover cluster requires network connectivity among nodes and between clients and nodes. Problems with a network adapter or other network device (either physical problems or configuration problems) can interfere with connectivity.
Events
| Event ID | Source | Message |
|---|---|---|
Microsoft-Windows-FailoverClustering |
Cluster network interface '%1' for cluster node '%2' on network '%3' is unreachable by at least one other cluster node attached to the network. The failover cluster was not able to determine the location of the failure. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges. | |
Microsoft-Windows-FailoverClustering |
Cluster network interface '%1' for cluster node '%2' on network '%3' failed. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges. | |
Microsoft-Windows-FailoverClustering |
Cluster network '%1' is partitioned. Some attached failover cluster nodes cannot communicate with each other over the network. The failover cluster was not able to determine the location of the failure. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges. | |
Microsoft-Windows-FailoverClustering |
Cluster network '%1' is down. None of the available nodes can communicate using this network. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges. | |
Microsoft-Windows-FailoverClustering |
Cluster IP address resource '%1' failed to come online. Ensure the network property '%2' matches a cluster network name or the address property '%3' matches one of the subnets on a cluster network. If this is an IPv6 Address type, please verify that the cluster network matching this resource has at least one IPv6 prefix that is not link-local or tunnel. | |
Microsoft-Windows-FailoverClustering |
Attempting to use IPv4 for '%1' network adapter failed. This was due to a failure to disable IPv4 auto-configuration and DHCP. IPv6 will be used if enabled, else this node may not be able to participate in a failover cluster. | |
Microsoft-Windows-FailoverClustering |
Network '%1' which has been disabled for failover cluster use, was found to be the only currently possible network that node '%2' can use to communicate with other nodes in the cluster. This may impact the node's ability to participate in the cluster. Please verify network connectivity of node '%2' and enable at least one network for cluster communication. Run the Validate a Configuration wizard to check your network configuration. | |
Microsoft-Windows-FailoverClustering |
Cluster node '%1' lost communication with cluster node '%2'. Network communication was reestablished. This could be due to communication temporarily being blocked by a firewall or connection security policy update. If the problem persists and network communication are not reestablished, the cluster service on one or more nodes will stop. If that happens, run the Validate a Configuration wizard to check your network configuration. Additionally, check for hardware or software errors related to the network adapters on this node, and check for failures in any other network components to which the node is connected such as hubs, switches, or bridges. |
