fence_kdump_send - send kdump acknowlegement message to cluster nodes
fence_kdump_send [OPTIONS]... [NODE]...
fence_kdump_send is a utility used to send messages that acknowledge that the node has entered the kdump crash recovery service. This utility is intended to be used the the fence_kdump agent as a means detect that a failed node has entered the kdump crash recovery service. The fence_kdump_send utility is typically run from within the kdump kernel after a cluster node has encountered a kernel panic. Once the cluster node has entered the kdump crash recovery service, fence_kdump_send will periodically send messages to all cluster nodes. When the fence_kdump agent receives a valid message from the failed node, fencing is complete.
