Cannot remediate NSX prepared Host that are stateless

Products

• VMware NSX

Issue/Introduction

• This issue affects NSX 4.2.1, and upgrading to this version will result in encountering the problem.
• Reboots of stateless hosts can cause this issue 
• The ESXi are NSX prepared and are stateless , so they need an auto-deploy server to provide the required start files when hosts power on.
• In the process of the upgrading the NSX vibs on the  ESXI and you use Host profiles to remediate the following ERROR is generated:  "Host profile apply failed with error: NSX Switch configuration failed in NSX. Please check transport node realization status in NSX for current status and error details."
•  Log lines similar to the below are encountered in /var/log/nsxaVim.log
  

  2025-01-28T09:51:05Z nsxaVim: [2107567]: ERROR Failed to fetch or update ports dvs (## ## ## ## ## ## ## ## ## ## ## ##): {'fault': 'NotFound', 'msg': 'The object or item referred to could not be found.', 'faultMessage': []}^@

Environment

NSX 

Cause

The code assumes that there DVS and ports exist on the host but at this time, the stateless host only has the temporary DVS (with prefix M-), and fails as a result of this .

Resolution

This is a known issue impacting VMware NSX .

Workaround 

1. Place the ESXI into Maintenance mode ,move the host to the Datacenter level of the vCenter Inventory
2. Once the ESXI has been removed from the cluster it should begin uninstalling NSX from the host automatically. 
   To confirm that NSX vibs have been removed run the below command on the ESXI shell 
    esxcli software vib list | grep nsx
   
   
3. Place the ESXI back into the NSX prepared cluster 
4. Now use Host-profiles to remediate the ESXI
