Hi Fischer, Mikolaj,
Based upon the query It seems that the "Azure Stack HCI Orchestrator Service" is missing, which is essential for the deployment of your 3-node HCI cluster on the DELL AX-750 servers.
Please ensure that Azure Stack HCI was installed correctly. You might want to re-run the installation to make sure that all components, including the orchestrator service, are properly installed.
Use PowerShell to check if the service is present:
Get-Service 'Azure Stack HCI Orchestrator Service'
If it is not found, a reinstallation or repair of the Azure Stack HCI setup may be necessary.
Analyze the logs you've collected for any specific errors during the deployment phase, particularly related to the ECE (Edge Compute Environment) and module loading.
Ensure that all necessary Azure Arc extensions are installed and updated. Sometimes, outdated extensions can lead to deployment issues.
Please refer the below documents which will be helpful to troubleshoot the issue:
Review deployment prerequisites for Azure Stack HCI, version 23H2
Install the Azure Stack HCI, version 23H2 operating system
Register your servers and assign permissions for Azure Stack HCI, version 23H2 deployment
