Network Interface for Heartbeat shows down

    we configured two node cluster with HACMP 5.4 and AIX 5.3 TL 6. everything went fine except for the heartbeat network interface shows down in the clstat and "cldisp -a" commands although the interface is UP and I can ping and ssh both nodes from each other.

    Also we configured the etherchannel for both service and heatbeat in the two nodes:
    en6 for heartbeat
    en7 for service

    what I can see from cllsif command:
    Adapter Type Network Net Type Attribute Node IP Address Hardware Address Interface Name Global Name Netmask Alias for HB

    chelsea1 boot net_ether_01 ether public chelsea1_node 10.9.9.9 en7 255.255.254.0
    chelsea2_svc service net_ether_01 ether public chelsea1_node 10.6.130.14 255.255.254.0
    chelsea1_svc service net_ether_01 ether public chelsea1_node 10.6.130.11 255.255.254.0
    chelsea1_rac service net_ether_02 ether private chelsea1_node 10.0.6.5 en1 255.255.255.0
    chelsea2 boot net_ether_01 ether public chelsea2_node 10.9.9.10 en7 255.255.254.0
    chelsea2_svc service net_ether_01 ether public chelsea2_node 10.6.130.14 255.255.254.0
    chelsea1_svc service net_ether_01 ether public chelsea2_node 10.6.130.11 255.255.254.0
    chelsea2_rac service net_ether_02 ether private chelsea2_node 10.0.6.4 en5 255.255.255.0

    the HACMP didn't pick up the en6 interface for the private (heartbeat) lan. it picked the two interfaces (en1 and en5) that made up the en6 in etherchannel and I think this is what makes the interface down.
    I tried to remove the interfaces and add them again with interface en6 but once I choose the network type to be private and synchronize the cluster, it gets back the old configuration. how can I fix that??

    I hope my issue is clear and thanks in advance.

And although I'm not familiar with setting an interface as the heartbeat there still should be a way to test the heartbeat to make sure they see/communicate with each other from each node in the cluster. Have you done that yet?
    Good luck.
