VCF Installer failed new deployment validation due to incorrect SDDC manager hostname

Products

• VMware SDDC Manager

Issue/Introduction

When deploying VCF 9 where an existing SDDC manager exists, the installation fails with the error:

Existing SDDC Manager Configuration: Failed

Incorrect SDDC Manager hostname '<YOUR_FQDN>' provided whilst using the option to reuse VCFInstaller,expected hostname '127.0.0.1'.

Environment

VCF 9.0

Cause

The FQDN and/or hostname of the existing SDDC manager does not match what was entered into the installer.

Resolution

1. Review your existing SDDC Manager in vCenter and ensure that the FQDN matches the hostname that the VCF Installer is expecting.
2. Review/ update the hostname on your existing SDDC Manager to ensure it matches the hostname that the VCF Installer is expecting and is reflected in vCenter.
