Environment

HCX 4.x

Cause

• The L2E segment that is stretched via HCX-NE is modified/removed on the destination NSX directly. This causes the HCX DB to be out of sync with the logical-switch config segment on NSX.
• Modifying the HCX extended L2E Segment outside of HCX is an unsupported operation. Refrain from making such changes.

Resolution

To recover from this condition, perform the steps below.

• Force unextend the affected network
  • Log in to your VMware HCX connector.
  • Navigate to Services > Network Extension.
  • Select the network(s) you want to unextend.
  • Expand the network entry to reveal more options.
  • Check the box for Force Unextend Network!.
  • Click the Unextend button.
  • Confirm the action in the dialog box that appears. 

Refer to the documentation :-Removing a Network Extension

• Delete the HCX L2E segment from Cloud/Destination NSX. Ensure that there are no VMs attached to this segment before deleting it.
  • Login to the NSX GUI as user admin
  • Navigate to the Networking Tab
  • Click on the Segment
  • Find the L2E segment, click on the 3 vertical dots and Delete.
