"Transport Nodes <List of UUID's> not part of default overlay transport zone <UUID> on NSX" When selecting a zone in vSphere when preparing a Supervisor Cluster

Products

• VMware NSX

Issue/Introduction

• You receive an incompatibility warning when you select a vSphere Zone during the creation of a Supervisor Cluster in vCenter.

• The error message indicates that the transport nodes are not part of the default overlay transport zone:

"Transport Nodes <List-of-Transport-node-UUID's> not part of default overlay transport zone <UUID> on NSX."

Environment

VCF 9.1

Cause

You have attempted to configure a Supervisor Cluster on an ESX clusters that is configured with a custom (non-default) overlay transport zone in NSX.

Currently, Supervisor Cluster configurations and certain network span objects require the host clusters to be associated with the NSX default overlay transport zone.

Resolution

You can attempt to resolve the association mismatch by first removing the zone/cluster association via the vCenter Command Line Interface (DCLI) and then changing the default overlay transport zone.
 
Remove the partially create vSphere zone association with the cluster:

1. Log into the vCenter Server Appliance (VCSA) shell as root user.

2. Switch to dcli interactive mode: dcli +i

3. Then check the current zone/cluster associations, using the vSphere zone you where selecting:

   com vmware vcenter consumptiondomains zones cluster associations get --<vSphere-zone-name>

   Note: This will ask for vCenter credentials to run the command.

4. The result should show one or more cluster MOID, starting with domain-c####

5. Next check if the Supervisor is enabled on the cluster:

   com vmware vcenter consumptiondomains zones cluster usage get --<vSphere-zone-name>

6. If it returns a result such as the following (in_use: True), it implies the supervisor is still using the cluster and must be disabled in vCenter first:

   usages:

   - cluster: domain-c####

   in_use: True

7. Once disabled (in_use: False), proceed and remove the zone/cluster association:

   com vmware vcenter consumptiondomains zones cluster associations remove --clusters domain-c#### --<vSphere-zone-name>
Note: Replace --clusters domain-#### with the result returned above.

 
Now change the default transport zone to the transport zone which is used to prepare the cluster.

Note: This may be prevented in NSX if the default transport zone is in use in other projects, before proceeding, ensure the default transport zone is not in use.

1. In the NSX UI, go to System > Fabric > Transport Zones

2. Click the 3 vertical dots (Hamburger menu) to the side of the Transport zone which you intend making the default transport zone and Click Set As Default Transport Zone.

Next go back into vSphere and select the vSphere zone to use for the Supervisor cluster preparation and continue.
