Perform Brownfield Environment Validation fails with "The vCenter Server virtual machine is not connected to a distributed virtual port group" VCF 9.1

Products

• VMware SDDC Manager / VCF Installer
• VMware Cloud Foundation

Issue/Introduction

Validation fails during domain sync or import domain workflow with the error: 

"The vCenter Server virtual machine is not connected to a distributed virtual port group"

Environment

VMware Cloud Foundation 9.x

Cause

This issue occurs when multiple Distributed Virtual Switches (DVS) in the SDDC Manager database share the same source_id, causing validation to target the incorrect DVS.

Resolution

This issue will be fixed in VCF 9.1.1

Validate duplicate source_ids:

1. SSH into the SDDC Manager with the vcf user and then elevate to root with su
2. Run this query to identify if duplicate source_id entries exist:
   
   

   psql -h localhost -U postgres -d platform -c "select source_id,id from vds"

   Example of an output with duplicate VDS source_ids
   
   

    source_id |                  id
   -----------+--------------------------------------

    dvs-19    | dff02e60-96d7-45c2-91dd-2b10a85d61f9

Workaround:

1. SSH into the SDDC Manager with the vcf user and then elevate to root with su. 
   
   
2. Copy the below command to disable the check.
   
   

    echo "vcf.import.guardrails.vcenter.vm.dvpg.skip=true" >> /etc/vmware/vcf/operationsmanager/application-prod.properties
   

3. Restart the operationsmanager service 
   
   

   systemctl restart operationsmanager

4. Verify the service is active 
   
   

   curl localhost/operationsmanager/about

   
   Example:
   

   {"id":"a17d507f-d7bb-405d-af2f-09cc04d61cb5","name":"OPERATIONS_MANAGER","version":"9.1.0.0.25371089","status":"ACTIVE","serviceUrl":"http://localhost/operationsmanager","description":"Operations Manager"}

5. Retry the Sync task from the VCF Operations UI.
