Troubleshoot Azure portal deployment validation issues for Azure Stack HCI, version 23H2

  • Article

Applies to: Azure Stack HCI, version 23H2 running 2405 or later

This article provides guidance on how to troubleshoot deployment validation issues experienced during the deployment of your Azure Stack HCI cluster via the Azure portal.

Error - deployment validation failure

When deploying Azure Stack HCI, version 23H2 via the Azure portal, you might encounter a deployment validation failure. The "Azure Stack HCI Network - Check network requirements" validation task fail with the following error:

Could not complete the operation. 400: Resource creation validation failed. Details:
[{"Code":"AnswerFileValidationFailed","Message":"Errors in Value Validation:\r\nPhysicalNodesValidator
found error at deploymentdata.physicalnodes[0].ipv4address: The specified  for 
\u0027deploymentdata.physicalnodes[0].ipv4address\u0027 is not a valid IPv4 address.
Example: 192.168.0.1 or 192.168.0.1","Target":null,"Details":null}].

If you go to the Networking tab in Azure portal deployment, within the Network Intent configuration, you could see the following error:

The selected physical network adapter is not binded to the management virtual switch.

Cause

This issue occurs on deployments triggered after August 6. The issue happens if the deployment validation was triggered on the cluster and the validation result was a failure, with subsequent validation retries.

The issue occurs for the following reason:

  • Validation on the device creates a VM switch for network related tests and is deleted at the end of tests.
  • DeviceManagementExtension extension isn't detecting the deletion of the VM switch.

The multi-step resolution process includes the following steps:

Note

All the steps in this article need to be performed on the seed node.

Remove the lock from the seed node

Follow these steps to remove the lock from the seed node:

  1. To remove the lock, in the Azure portal, go to the object via the resource group or within Machines - Azure Arc.
  2. In the left-pane, go to Settings > Locks. You should see a lock named DoNotDelete. This is the automatic resource lock that is created when the node is onboarded.
  3. Select Delete against the lock.

If you attempt the steps in the next section without removing the lock, the Delete command fails with the following error:

Some resources failed to be deleted (run with `--verbose` for more information):
/subscriptions/<subid>/resourceGroups/<rgname>/providers/Microsoft.HybridCompute/machines/<Machine Name>/providers/Microsoft.AzureStackHCI/edgeDevices/default

Here's the example output when run with the --verbose switch:

(ScopeLocked) The scope '/subscriptions/<Subscription ID>/resourceGroups/<Resource Group Name>/providers/Microsoft.HybridCompute/machines/<Machine Name>/providers/Microsoft.AzureStackHCI/edgeDevices/default' cannot perform delete operation because following scope(s) are locked: '/subscriptions/<subid>/resourceGroups/<rgname>/providers/Microsoft.HybridCompute/machines/<Machine Name>'. Please remove the lock and try again.
Code: ScopeLocked
Message: The scope '/subscriptions/<subid>/resourceGroups/<rgname>/providers/Microsoft.HybridCompute/machines/<Machine Name>/providers/Microsoft.AzureStackHCI/edgeDevices/default' cannot perform delete operation because following scope(s) are locked: '/subscriptions/<subid>/resourceGroups/<rgname>/providers/Microsoft.HybridCompute/machines/<Machine Name>'. Please remove the lock and try again.

Remove the validation error

With the lock removed, follow these steps to remove the validation error.

  1. Connect to the seed node. Run the following PowerShell command:

    Get-VMSwitch

  2. Check the output of the Get-VMSwitch command for any unexpected VM switches, for example, the switch that gets created during the Network Validation step and has a name similar to: "ConvergedSwitch(compute_management)". The exact name of the switch depends on the chosen network intent configuration.

  3. If a VM switch that you didn't intentionally create exists, remove the switch. Run the following PowerShell command:

    Remove-VMSwitch -Name "<VM Switch Name>" -Force

    Make sure to use the VM switch name from the Get-VMSwitch command. If you didn't intentionally create a VM switch, the Get-VMSwitch command has no results. The failure occurs because the Network Validation Step cleaned up the VM switch, but the DeviceManagementExtension didn't detect the cleanup.

Continue with the cleanup steps.

Clean up the Edge Device Azure Resource with incorrect VM switch information

After the VM switch on the device is removed, clean up the Edge Device ARM resource containing the incorrect VM switch information via the Azure CLI.

  1. On a client that can access to Azure, verify install or install AZ CLI: Install Azure CLI on Windows

    • You can verify install by running: az
    • If installed, this outputs a "Welcome to Azure CLI!" message with available commands.

  2. Sign in to Azure with Azure CLI. Run the following command:

    az login --tenant <tenant ID> --use-device-code

    For more information, Sign in interactively with Azure CLI

  3. To set a specific subscription, run the following command:

    az account set --subscription "<Subscription ID>"

    Replace the value in the above example command with the appropriate value for <Subscription ID>.

  4. Output the data stored within the edgeDevices resource that has the incorrectly stored VM Switch information. Run the following command:

    az resource show --ids "/subscriptions/<Subscription ID>/resourceGroups/<Resource Group Name>/providers/Microsoft.HybridCompute/machines/<Machine Name>/providers/Microsoft.AzureStackHCI/edgeDevices/default"

    Replace the values in the above example command with the appropriate values for:<Subscription ID>, <Resource Group Name>, and <Machine Name>.

    Here's an example output:

    az resource show --ids "/subscriptions/<Subscription ID>/resourceGroups/<Resource Group Name>/providers/Microsoft.HybridCompute/machines/ASRR1N26R15U33/providers/Microsoft.AzureStackHCI/edgeDevices/default"

    The output of this command shows quite a bit of detail about the <Machine Name> used in the command. Near the bottom of the output, there's a section for "switchDetails", which will more than likely show the following (which is the Validation VM Switch that was created and cleaned up on the device, but wasn't detected by the DeviceManagementExtension and updated cloud-side): "switchName": "ConvergedSwitch(managementcompute)", "switchType": "External"

  5. After confirming the show command worked by outputting the edgeDevices data, and likely confirming the "switchDetails", it is time to delete the resource from ARM so it can be refreshed appropriately from the seed node.

    Note

    Deleting the edgeDevices data is a safe action to perform, but it should only be performed when explicitly stated. Do not perform this action unless advised to do so.

  6. Delete the edgeDevices resource, which has the incorrectly stored VM switch information. Run the following command:

    az resource delete --ids "/subscriptions/<Subscription ID>/resourceGroups/<Resource Group Name>/providers/Microsoft.HybridCompute/machines/<Machine Name>/providers/Microsoft.AzureStackHCI/edgeDevices/default"

    Replace the values (remember to remove the <> characters as well) with the appropriate values for: <subGUID> <resourceGROUPNAME> <Machine Name>

    This is the same resource --ids from the show, so you can just use that same string. In fact, you could just "up arrow" in the console and replace show with delete.

    Here's an example output:

    `az resource delete --ids "/subscriptions/<Subscription ID>/resourceGroups/<Resource Group Name>/providers/Microsoft.HybridCompute/machines/<Machine Name>/providers/Microsoft.AzureStackHCI/edgeDevices/default"

    When run, there's no output from this command. The command works and returns the command prompt, or presents an error. It shouldn't present an error, but if it does, that will require more troubleshooting.

  7. Verify the deletion of the resource by running the show command again. Here's an example output:

    (ResourceNotFound) The resource 'Microsoft.HybridCompute/machines/<Machine Name>/providers/Microsoft.AzureStackHCI/edgeDevices/default' could not be found.
Code: ResourceNotFound
Message: The resource 'Microsoft.HybridCompute/machines/<Machine Name>/providers/Microsoft.AzureStackHCI/edgeDevices/default' could not be found.

Refresh the cloud edgeDevices data

With the ARM resource and all the unintentional VM switches removed, refresh the cloud-side edgeDevices data again.

Follow these steps to refresh the cloud data:

  1. Restart the DeviceManagementService on the seed node. Run the following PowerShell command:

     Restart-Service DeviceManagementService

  2. Wait a few minutes and then verify that the cloud edgeDevices data is updated and reflects the current state. Run the show command again and review the output. Make sure that the output no longer contains any unexpected VM switches, namely:

    "switchName": "ConvergedSwitch(managementcompute)", "switchType": "External"

Restart the deployment via Azure portal

With device and cloud data now back in sync, you can go to the Azure portal and provide the deployment inputs. The previous step prevents any cached information from previous attempts.

Follow these steps in the Azure portal:

  1. On the Basics tab, provide your inputs (by selecting from the dropdowns once again) to the fields from the top.

  2. Uncheck the nodes at the bottom of the page.

  3. Revalidate the reselected nodes.

  4. Confirm the information on the subsequent pages. You should see the following changes:

    • On the Networking page, you should no longer see the The selected physical network adapter is not binded to the management virtual Switch error that might have been seen previously.
    • On the Validation page at the end, if you're past the original issue, the deploymentdata.physicalnodes[0].ipv4address is not a valid IPv4 address error won't be displayed.

  5. If no other validation issues occur, start the deployment.

Recreate the lock on the seed node resource

After the mitigation is complete, we strongly recommend that you recreate the lock on the resource.

Follow these steps to recreate the lock:

  1. In the Azure portal, go to the object via the resource group or within Machines - Azure Arc.
  2. Go to Settings > Locks.
  3. Select + Add at the top of the page.
    1. For Lock name, enter DoNotDelete.
    2. For Lock type, select Delete from the dropdown.
  4. Select OK to save the lock.
