    Hi everyone,

    We are setting up a PowerHA 6.1, 2 nodes cluster. And for heartbeating, we use IP Aliases.
    Our configuration is below (in "normal operation" mode):
    Node 1:
    en0 :
    192.168.140.81 => boot address
    192.168.176.1 => heartbeat alias address
    192.168.140.89 => service IP address 1

    Node 2:
    en0 :
    192.168.140.82 => boot address
    192.168.176.2 => heartbeat alias address
    192.168.140.79 => service IP address 2

    We would like to know if PowerHA 6.1 uses broadcast or multicast for hearbeating.
    Thanks in advance.

    neither.

    6.1 uses RSCT 2.x topology services (topsvcs) for cluster heartbeat. RSCT has multiple options for heartbeat, here unicast UDP is chosen.

    7.1 drops topsvcs and uses caa (clusteraware aix) instead which uses multicast IP heartbeat.
