Network-failure recovery

When a network interface enters the Failed state, the Cluster service triggers the failure of all IP Address resources that use that network interface. When an IP Address resource fails, the Cluster service treats it like the failure of any other resource: All resources that depend on the IP Address resource fail, and the Cluster service uses the failover policy that you have set to determine whether or not to fail over the resource group.

The Cluster service does not trigger the failure of IP Address resources when a network interface enters the Unreachable state. If the network interface is in the Unreachable state, the Cluster service has not isolated the network problem enough to implement an appropriate recovery policy. When a network interface enters the Unreachable state, investigate the state of the network to determine whether or not to cause a manual failover of resource groups.
