Administering Global Heartbeats

Use Cluster Explorer to add, modify, and delete heartbeats in a global cluster environment. Icmp heartbeats send Icmp packets simultaneously to all IP addresses; IcmpS heartbeats send individual Icmp packets to IP addresses in serial order. Global clustering requires a minimum of one heartbeat between clusters; the Icmp heartbeat is added when the cluster is added to the environment. You can add additional heartbeats as a precautionary measure.
