Unable to select an Available Cloud when adding an NSX-T Cloud in Cloud Director

Products

• VMware Cloud Director

Issue/Introduction

Symptoms:

• Attempting to Add an NSX-T Cloud in the Provider UI of Cloud Director under Resources > Infrastructure Resources > NSX-ALB > NSX-T Clouds.
• When adding an NSX-T Cloud the wizard will show all available Clouds, but you are not able to select the Cloud as it is greyed out.
• The available NSX-T Cloud does not show Associated Network Pool or Transport Zone values.

Environment

VMware Cloud Director 10.x

Cause

This issue occurs when the NSX-T connection in Cloud Director and NSX Advanced Load Balancer are not using the same IP address or FQDN.

When registering the NSX-T Manager we cannot mix IP addresses and FQDNs, we must chose one or the other for all solutions including Cloud Director and NSX Advanced Load Balancer.

Resolution

Update the NSX-T connection configuration in Cloud Director and NSX Advanced Load Balancer so both are using the IP address or both are using the FQDN.

Once both are using the same connection details retry the operation to add an NSX-T Cloud in Cloud Director.

Additional Information

These requirements regarding the FQDN or IP address of the NSX-T Manager are outlined in the Cloud Director documentation here:

Managing NSX Advanced Load Balancing, Register a Controller Instance:

Note:
The FQDN or IP address that you use to register NSX-T Manager with NSX Advanced Load Balancer must match the FQDN or IP address of the NSX-T Manager instance that you used to register NSX-T Data Center with VMware Cloud Director.
