NSX Configuration on Host Transport Nodes cycles between states including 80% and Partial Success

Products

• VMware NSX

Issue/Introduction

NSX Configuration may hang on 80% Enabling for a long time

But eventually transitions to Partial Success.  The details for the Configuration State contain the Error message: "LogicalSwitch full-sync: Status is in-progress on '1' transport nodes."

Eventually, the NSX Configuration will loop and begin again.

The looping can be validated through the API and retrieving the state of all transport nodes. 

GET API '/api/v1/transport-nodes/state' will show the following for each looping transport node:

{

...

"failure_message": "Host configuration failed.  Number of retries: ###.  Next retry attempt will be ..."

...

"transport_node_id": "########-####-####-####-############",

...

}

Environment

VMware NSX-T Data Center 3.x

Cause

A VDS is not being correctly realized on the Host Transport Node.

Resolution

Remove the affected Host from the cluster so it will have the Transport Node Profile removed.

Re-add the affected Host to the cluster so the Transport Node Profile can be re-applied.

The NSX Configuration is now expected to reach Success.
