• On the System > Configuration > Fabric > Transport Zones page of the NSX UI, there is no nsx-vlan-transportzone entry present.

Environment

VMware NSX

Cause

The system transport zone, 'nsx-vlan-transportzone', was deleted at some point prior to starting the 9.x upgrade and replaced with a new default VLAN transport zone.

This is a known issue impacting VMware NSX. There is currently no resolution.

Additional Information

If you are contacting Broadcom support about this issue, please provide the following:

• NSX Manager support bundles.
• The PolicyTransportZone.txt file generated by running the following command on one of the manager nodes:
  
  /opt/vmware/bin/corfu_tool_runner.py -o showTable -n nsx -t PolicyTransportZone > PolictyTransportZone.txt

 

Note: If the upgrade succeeds while the nsx-vlan-transportzone default VLAN-backed transport zone is missing, the issue noted in After an upgrade to NSX 9.0, the NSX UI is intermittently inaccessible. On the Appliances page, the cluster status shows as Unavailable and there are no details for any of the manager nodes will likely occur.
