+.SH NAME
+fence_kdump_send - send kdump acknowlegement message to cluster nodes
+.SH SYNOPSIS
+.B
+fence_kdump_send
+[\fIOPTIONS]\fR... [NODE]...
+.SH DESCRIPTION
+\fIfence_kdump_send\fP 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 \fIfence_kdump\fP
+agent as a means detect that a failed node has entered the kdump crash
+recovery service.
+The \fIfence_kdump_send\fP 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,
+\fIfence_kdump_send\fP will periodically send messages to all cluster
+nodes. When the \fIfence_kdump\fP agent receives a valid message from
+the failed node, fencing is complete.
