Azure Local 23H2 - Add-Server functionality not working

Question

We're trying to add a server back into a cluster that was failed and when we try to run the "Add-Server" command specified here: https://learn.microsoft.com/en-us/azure/azure-local/manage/add-server?view=azloc-24112

It gives this error:

VERBOSE: Looking up shared vhd product drive letter. WARNING: Unable to find volume with label Deployment VERBOSE: Suppressed Warning Unknown category for 'NuGet'::'GetDynamicOptions': 'Provider' The 'Add-Server' command was found in the module 'ScaleNodeOperations', but the module could not be loaded. For more information, run 'Import-Module ScaleNodeOperations'. + CategoryInfo : ObjectNotFound: (Add-Server:String) [], CommandNotFoundException + FullyQualifiedErrorId : CouldNotAutoloadMatchingModule

This is when attached to the cluster or from an individual node using the LCM account. ScaleNodeOperations gives this error:

Import-Module : The specified module 'ScaleNodeOperations' was not loaded because no valid module file was found in any module directory. + CategoryInfo : ResourceUnavailable: (ScaleNodeOperations:String) [Import-Module], FileNotFoundException + FullyQualifiedErrorId : Modules_ModuleNotFound,Microsoft.PowerShell.Commands.ImportModuleCommand

Answer 1

The error you're seeing clearly indicates that the ScaleNodeOperations PowerShell module is missing from the system:

Import-Module : The specified module 'ScaleNodeOperations' was not loaded because no valid module file was found in any module directory. 

This prevents the Add-Server cmdlet from running, since it's part of that module.

Verify Required Environment

Ensure you're doing this on a supported Azure Local server environment, such as Azure Stack HCI (especially if using 23H2), and logged in as Local Cluster Manager (LCM) with elevated (admin) privileges.

Check for Module Location Manually

Check if ScaleNodeOperations exists:

Get-Module -ListAvailable ScaleNodeOperations

If it doesn't appear, try looking manually:

Get-ChildItem -Path $env:ProgramFiles\WindowsPowerShell\Modules\ScaleNodeOperations -Recurse

Or search globally:

Get-ChildItem -Path "C:\Program Files\WindowsPowerShell\Modules" -Recurse -Directory | Where-Object { $_.N

Fix or Reinstall the Module. https://learn.microsoft.com/en-us/azure/azure-local/manage/add-server?view=azloc-24112

Make Sure NuGet Provider Is Installed (if using PSGallery)

The warning about NuGet suggests you might also be missing the NuGet provider:

Install-PackageProvider -Name NuGet -Force

And trust PSGallery:

Set-PSRepository -Name "PSGallery" -InstallationPolicy Trusted

After confirming the module loads successfully:Retry the Add-Server Command

Hope it helps!
