In this approach, delete all the three controller nodes, and add new controller nodes to maintain a fully functional three-node cluster.

VMware recommends deleting the NSX Controller cluster when any of the following conditions are true:
  • One or more controller nodes face catastrophic or unrecoverable errors.
  • Controller virtual machines are inaccessible and cannot be fixed.
In such cases, preferably delete all the controller nodes, even when some of the controller nodes seem healthy.

Redeploy a new controller cluster, and then update the controller state mechanism on the NSX Manager. Updating the controller state causes VXLAN to be resynchronized and the distributed logical routers to be redeployed.


  1. Log in to the vSphere Web Client.
  2. Navigate to Networking & Security > Installation and Upgrade > Management > NSX Controller Nodes.
  3. Delete all the three controller nodes. Select one node at a time and click the Delete (Delete Icon in vSphere Client. or Delete Icon in vSphere Web Client.) icon.
    When no controllers exist in the system, the hosts operate in "headless" mode. New virtual machines or migrated virtual machines will have networking issues until new controllers are deployed and the synchronization is completed.
  4. Deploy three new controller nodes to create a fully functional NSX Controller cluster.
    For detailed information about adding a controller cluster, see "Deploy NSX Controller Cluster" in the NSX Installation Guide.
  5. Resynchronize the controller state by clicking Actions > Update Controller State.
