  • Secondary—Redundancy group is passive and not passing traffic.
  • Lost—Node loses contact with the other node through the control link. Most likely to occur when both nodes are in a cluster one node is rebooted, or, because of a control link failure, one node cannot exchange heartbeats with the other node.
  • Unavailable—Node has not received a single heartbeat over the control link from the other node since the other node booted up. Most likely to occur when one node boots up before the other node or if only one node is present in the cluster.
