Considering Two node cluster environment. One liner I would say:

Heartbeat IP: This is the lan which is used to check the health of the other node. Default is 1 second.

Lock PV/VG: If there is some problem in heartbeat communication then to maintain the data consistency Lock PV/VG is used. The node which occupies the lock PV/VG first will reform the cluster after nodetimeout and other node will TOC.

For more details on the same and about cluster environments, please refer the link mentioned above.
