Hey Jaco Loubser

Thanks for reaching out Q/A. Here are some steps you can take to troubleshoot and possibly resolve this issue:

Check for Previous Operations: Make sure there are no previous operations still running. Sometimes, if an operation is already in progress, it can block new operations. Wait for any ongoing deployments to complete.

Custom Resource Handling: If this continues to be an issue, try deleting any Custom Resources related to the deployment and redeploy the Arc components. This can sometimes clear up conflicts that cause errors.

Namespace Conflicts: Consider checking for namespace conflicts. Log in to your cluster Look for customLocationId in the annotations and delete it if found.

Arc Extension Installation: Ensure that the Arc extension is correctly installed. Refer to the Deployment Guide for Azure Arc Extensions to make sure that you've followed the proper steps.

Prerequisites Validation: Verify that all prerequisites for the Azure Arc deployment are met as per your setup. For example, check if your SCVMM management server is up to date, and ensure that your private cloud setup has enough resources available (4 vCPUs, 16 GB RAM, 100 GB free disk space).

Answer 2

It seems that the Resource Bridge in Azure Arc was successfully deployed but where waiting on the heartbeat of the Azure Resource Bridge VM Appliance. I resumed the installation and after several hours I doubted if the installation would succeed. I installed Windows Admin Center and connected to the azurelocal cluster domain FQDN and could see that the resource bridge control plane VM was running. When logging into the console via RDP it the console log did not show any errors. After another hour the resource bridge in Azure showed status running and the "Deploy Arc infrastructure components" phase in the deployment was completed.
