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 failed node, fencing is complete.
