  • You have recently tried to deactivate/detach the NSX Manager cluster.
  • You have recently replaced one or more of your Local Manager nodes.
  • Local Managers (LM) show Unknown State from Global Manager UI.
  • All services on Global Manager show as stable.
  • There is no functional impact of the Local Managers.
  • Entries similar to the below will be seen on the Local NSX Manager due to the cluster deactivation failure:

VMware NSX-T Data Center


The cause of this issue is that the Management Plane is not stable when the Deactivate Cluster operation is initiated, this results in stale entries in the Local NSX Managers.


This is a known issue impacting NSX-T Data Center.

Collect and inspect the API output for stale NSX Manager nodes
Delete the stale nodes.
DELETE /api/v1/cluster/nodes/<node-UUID>
