SYNOPSIS

DESCRIPTION
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.

nodes. When the fence_kdump agent receives a valid message from
the failed node, fencing is complete.
