The

Starts the heartbeat service on two physical machines separately:
#  service Pulse start
starting Pulse:                                            [ ok  ]
at this time, can be seen on the main physical machine 10.5.20.12 load Balancer network card has been started,
and 10.5.20.13 is not on this network card:
