NSX Host or Edge Transport Nodes have a status of "Unknown" and Tunnels are "Not Available" or "Validation Errors"

Products

• VMware NSX

Issue/Introduction

• NSX may have been recently upgraded to 4.x.
• NSX Transport Nodes (Host or Edge) status is 'Unknown' or NSX configuration shows 'Validation Errors' in the NSX UI or NSX API 
  
  To get a list of all Transport Nodes and their IDs:
  
  

  GET https://<NSX_MANAGER>/api/v1/transport-nodes/

  
  To get the status of a specific Transport Node:
  
  

  GET https://<NSX_MANAGER>/api/v1/transport-nodes/<tn-id>/status

• Clicking on Transport Node 'Validation Errors' in the NSX UI shows errors similar to the below:
  
  

  600: The requested object: <TransportZoneProfile-UUID> could not be found. Object identifiers are case sensitive."

• NSX Transport Nodes tunnel status may show 'Not Available' in the NSX UI.
  
  
  
  
  
• No data plane impact has been reported.
• NSX Manager log /var/log/proton/nsxapi.log has a log entry similar to the below:
  
  

  "The requested object : TransportZoneProfile/<TransportZoneProfile-UUID> could not be found."

• The above Transport Zone Profile UUID is not present when queried via API:
  
  

  GET https://<NSX_MANAGER>/api/v1/transportzone-profiles?include_system_owned=true

• The above Transport Zone Profile UUID cannot be found in NSX or VC global search.
• The NSX manager log /var/log/search/elasticsearch_index_indexing_slowlog.log has a log similar to example:
  
  

  [{"resource_type":"BfdHealthMonitoringProfile","profile_id":"UUID_in_Validation_Error"}]}],"vmk_install_migration":[],"pnics_uninstall_migration":[],"vmk_uninstall_migration":[],"not_ready":false}],"resource_type":"StandardHost]

Environment

• VMware NSX-T Data Center
• VMware NSX

Cause

The status of the Transport Nodes (TNs) are unknown because the Transport-Zone Profile (TZP) which is being referenced does not exist. The reasons why the referenced Transport-Zone Profile (TZP) is not present in the system can be due to multiple reasons:

• In previous versions of NSX, it was possible in policy mode to update or delete a Transport-Zone Profile (TZP), even if it was in use by a Transport Nodes(TN) or Transport-Node Profile(TNP).
• In some cases, Aria Operations for Networks creates a Transport-Zone Profile (TZP) and when Aria Operations for Networks is removed, Transport-Zone Profile(TZP) are deleted.  Validation has been added in newer versions to avoid this issue.

Resolution

To resolve this issue for ESXi hosts and Edge nodes, open a support case with Broadcom support selecting NSX as the product.
