Issue/Introduction

• Stale transport node exists. For example:
  • Transport Node was removed from inventory without completing NSX Uninstallation described in Uninstalling NSX from a Host Transport Node.
• Deleting the stale transport node with DELETE /api/v1/infra/sites/default/enforcement-points/default/host-transport-nodes/<TN_ID>?force=true&unprepare_host=false throws Error:

Environment

NSX 4.1

Cause

Deleting a transport node is not allowed if a host is part of TNP (Transport Node Profile) applied cluster.
Moving the host out of TNP applied cluster is required before attempt to delete the host.

Resolution

1. Navigate to vSphere Client.
2. Move the corresponding host out of the TNP applied cluster.
3. Re-try delete operations such as:
   DELETE /api/v1/infra/sites/default/enforcement-points/default/host-transport-nodes/<TN_ID>?force=true&unprepare_host=false

 

Additional Information

Installing or Upgrading NSX on an ESXi host fails reporting the node already exists
