In order for an HACMP cluster to recognize and respond to failures, it must continually check the health of the cluster. Some of these checks are provided by the heartbeat function. Each cluster node sends heartbeat messages at specific intervals to other cluster nodes, and expects to receive heartbeat messages from the nodes at specific intervals. If messages stop being received, HACMP recognizes that a failure has occurred.

Heartbeats can be sent over:
        TCP/IP networks
        Point-to-point networks
        Shared disks.

The heartbeat function is configured to use specific paths between nodes. This allows heartbeats to monitor the health of all HACMP networks and network interfaces, as well as the cluster nodes themselves.

The TCP/IP heartbeat paths are set up automatically by RSCT; you have the option to configure point-to-point and disk paths as part of HACMP configuration.

HACMP passes the network topology you create to RSCT. RSCT Topology Services provides the actual heartbeat service, setting up the heartbeat paths, then sending and receiving the heartbeats over the defined paths. If heartbeats are not received within the specified time interval, Topology Services informs HACMP.
