| Description | Cluster network Private Heartbeat Network(1)(2) is down. None of the available nodes can communicate using this network. If the condition persists, check for failures in any network components to which the nodes are connected such as hubs or switches. |
| Event Information | According to Microsoft: For intra-node communications, cluster nodes communicate over User Datagram Protocol (UDP) port 3343. Each node in the cluster periodically exchanges sequenced, unicast UDP datagrams with every other node in the cluster. The purpose of this exchange is to determine whether all nodes are running correctly and to monitor the health of network links. The cluster network driver (Clusnet.sys) manages cluster communications. The cluster network driver performs the following functions: 1. Provides a uniform interface for cluster node communications that are independent of the network infrastructure. 2. Monitors the status of all communication paths in the cluster. 3. Routes intra-cluster messages over the optimal paths. 4. Detects node failures by using periodic messages that are known as "heartbeats". 5. Detects failures in network and TCP/IP communications. |
