trigger for a whole lost network MultiNiCB
In a common clusterenvironment there are sometimes failure situations where is no need to switch the service groups from one node to a another node in the cluster. one of this situations is a whole failed network. If the network fails simultaneously over all nodes the cluster framework attempt to start the Servicegroups in one other node in cluster. This behaviour drive the cluster to unnecessary actions and the servicegroup with the application becoming faulted on all clusternodes. In comparision to a single server this is more worst behaviour.
Therefore there is a need for a special trigger which freezes all servicegroups when the MultiNICB ressource fails simultaneously on all cluster nodes . This would prevent a lot of work after a whole lost network for all customers particularly if the cluster configured with a lot of servicegroups.
