One or more nodes are not connected to both cluster switches

Last Updated:


Applies to

  • MetroCluster
  • Cisco Nexus 
  • Cluster-Switch  


  • In a MetroCluster IP configuration using BES-53248 switches the following HM alert may come up even all connections to the Switch are online :

    Cluster-A::*> system health alert show
    Node: Node-A1
    Resource: Node-A1
    Severity: Major
    Indication Time: Mon May 10 17:59:20 2021
    Suppress: false
    Acknowledge: false
    Probable Cause: One or more nodes are not connected to both cluster switches.
    Possible Effect: If one cluster switch fails, "Node-A1" might lose
    access to the cluster.
    Corrective Actions: Verify that the switch "Switch_A1" is connected to the node "Node-A1".
