Error description

  • Customer configures a PowerHA unicast cluster with no
    sites. Both nodes have two adapters configured in the
    cluster. Customer halts the secondary node to test.
    PowerHA processes multiple fail_interface event followed
    by join_interface event for both adapters on the primary
    node, which have not actually failed.  Sometimes PowerHA
    processes a swap_adapter of the service IP address.
    
    This problem will also occur in a single adapter per
    node configuration.

Problem conclusion

  • Added the new tunable "no_if_traffic_monitor" to monitor the
    ADAPTER traffic.
    When this tunable value is set to 1, it indicates that don't
    monitor the interface traffic and also don't use the interface
    traffic to validate the adapter state.
    When this tunable value is set to 0, it indicates that monitor
    the interface traffic and also use the interface traffic to
    validate the adapter state.
