Issue/Introduction
In VMware Cloud Foundation (VCF) 9, instances may encounter a state where the Management vCenter is registered with a Workload domain NSX Manager, or vice versa (cross-registration). This document provides guidance on recovery and the supportability of FQDN/IP changes for these components.
* NSX Manager FQDN or IP updates fail during SDDC Manager validation.
* Management vCenter appears as a Compute Manager in the incorrect NSX Manager cluster.
Environment
VMware Cloud Foundation 9.x
Cause
Registration of vCenter Servers as Compute Managers to the wrong NSX Manager cluster bypasses SDDC Manager orchestration, leading to inventory inconsistencies.
Resolution
Modifying the FQDN of management components (SDDC Manager, vCenter, NSX) in an active VCF 9 environment is not officially supported.
To resolve cross-registration errors.
- Redeploy VCF (Recommended):
A full redeployment of the VCF environment ensures that all database records, certificates, and inter-component trusts are correctly established. For steps, see Deploying a New VMware Cloud Foundation Private Cloud.
