Environment

VMware NSX-T Data Center for vSphere 6.3.x

Cause

This issue occurs when the secondary NSX Manager is added to Primary NSX Manager, the three NSX Controllers are added to the secondary NSX Manager and a force sync for the NSX Controller is started. This force sync operation may fail because a Transport Zone UUID is not found. This is due to a race condition where the force sync operation is started before the Transport Zone UUID is created.

Resolution

This issue is resolved in VMware NSX-T Data Center for vSphere 6.4.2.

Workaround:

To work around this issue, start a manual force sync operation of the NSX Controllers by selecting the "Update controller State"on the Secondary NSX Manager in the Installation and Upgrade > Management.

 

Additional Information

Impact/Risks:
Secondary NSX Manager VNIs are not seen on the NSX Controllers after adding the secondary NSX Manager to Primary Manager hence data plane for those VNIs are impacted.
