Determine if the WildFire Cluster is in a Split-Brain Condition

When the appliances in a WildFire 2-node cluster enter a split-brain condition, the service failure(s) generate warnings in the WildFire CLI and managing Panorama (where available).
  1. (WildFire appliance CLI only) On a WildFire appliance controller, run:
    admin@WF-500>show cluster membership
    The affected WildFire cluster node displays Cluster:splitbrain next to Service Summary.
    The following example shows a node in a 2-node WildFire cluster in a split-brain condition:
    Service Summary:  Cluster:splitbrain
    Cluster name:     WF_Cluster_1
    Host name:        wf1
    Node name:        wfpc-009707000380-internal
    Serial number:    009707000380
    Node mode:        controller
    Server role:      True
    HA priority:      secondary

  2. (Panorama only) On the Panorama appliance that is managing the WildFire cluster:
    1. Select Panorama > Managed WildFire Clusters.
    2. In the Cluster Status column, check for the presence of cluster [splitbrain]. This indicates that the appliance is in split-brain mode.
