Issue/Introduction

This article provides steps to resolve duplicate portgroups when re-adding a ESXi host to the environment.

Symptoms:
  • This issue occurs after these steps have been completed:
  1. Create a Distributed Virtual Switch (DVS) and a port group in vCenter Server.
  2. Join the ESXi host to the DVS in vCenter Server.
  3. Create a VM on the ESXi host.
  4. Connected the VM to the port group of the DVS. 
  5. Disconnected the ESXi host from vCenter Server.
  6. Remove the ESXi host from vCenter Server inventory.
  7. Add the ESXi host to vCenter Server inventory again. The ESXi host is not member of the DVS at this time.
  8. Join the ESXi host to the DVS from vCenter Server. At this point the dvport used by the VM will not update the connected VM. vCenter will not have this port assigned and can assign it to another VM causing a conflict.
