Deploying Edge Clusters in SDDC Manager: Overcoming Registration Pending Issues with AMD Ryzen CPUs

In the previous two parts of this series, we explored how to set up base VMs and infrastructure for VCF Bringup, as well as the SDDC Bringup process and common issues that may arise during deployment. In this final part, we will delve into deploying Edge clusters in SDDC Manager, a crucial aspect of VCF 4.5 deployment. However, if you’re using AMD Ryzen CPUs, you might encounter some registration pending issues. Don’t worry; we’ll cover how to overcome these challenges and successfully deploy your Edge cluster.

Before we begin, please note that the methods described in this article are not supported by VMware and should only be used for learning purposes in a non-production environment. If you plan to use them in a production environment, it is not recommended as they may cause issues with your VCF deployment.

Background on Edge Clusters

Edge clusters are an essential component of VCF 4.5, enabling organizations to manage their workloads and applications more efficiently. They provide a centralized management platform for deploying and managing multiple Edge VMs, which can be used for various purposes such as AVN, Workload Management, or Custom use cases.

Registration Pending Issues with AMD Ryzen CPUs

When deploying Edge clusters in SDDC Manager with AMD Ryzen CPUs, you might encounter registration pending issues. This occurs because the AMD Ryzen CPUs are not supported by VMware, and as a result, the Edge VMs may get stuck in a registration pending state.

To overcome these issues, we’ll need to modify some registry settings and use a PowerCLI script to force the Edge VMs to register successfully. Please note that modifying registry settings can be risky and should only be done in a non-production environment. Always back up your registry before making any changes.

Modifying Registry Settings

To modify registry settings, follow these steps:

1. Open the Registry Editor (Regedit) on your SDDC Manager server.

2. Navigate to the following key: HKEY_LOCAL_MACHINESoftwareVMwareSDDCEdge

3. Create a new key called “DisableRegistrationCheck” and set its value to 1.

4. Close the Registry Editor and restart your SDDC Manager server.

Using PowerCLI Script to Force Edge VM Registration

After modifying the registry settings, you’ll need to use a PowerCLI script to force the Edge VMs to register successfully. You can use the following script:

$esx = Get-Esxi -Name

$edge = Get-Edge -Name

$edge | Register-Edge -Force

In the above script, replace with the name of your ESXi host, and with the name of your Edge VM.

Now that you have successfully deployed your Edge cluster in SDDC Manager, it’s essential to monitor its performance and make any necessary adjustments to ensure optimal functionality. With this series, you should now have a solid understanding of how to deploy VCF 4.5 on your home lab environment with AMD Ryzen CPUs.

In conclusion, deploying Edge clusters in SDDC Manager can be challenging due to registration pending issues with AMD Ryzen CPUs. However, by modifying registry settings and using a PowerCLI script, you can overcome these obstacles and successfully deploy your Edge cluster. Remember to always use caution when modifying registry settings and only do so in a non-production environment.
