Environment

VMware NSX-T Data Center

Cause

The issue occurs when vCenter has more than one VDS with the same UUID.

Resolution

NSX-T expects a unique VDS UUID on each vCenter.

Workaround:
Please make sure there are no duplicate VDS' on vCenter. You may need to create a new one and use that for NSX-T or remove the duplicate VDS.
