Azure Stack VM Network cannot delete

Tang, Ken 0

Cannot delete the AzStack VM Network, even i have clear out all of the related connection and interface.

Already tried in webUI and powershell, still got the same result.

admission webhook "deletionvalidationwebhook.infrastructure.azstackhci.microsoft.com" denied the request:

 | Deletion of default/**network name** failed. It is in use by other resources. Resource type:

 | *v1alpha1.AzStackHCILogicalNetwork

Hi Tang, Ken,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

Check that there are no resources dependent on the VM Network which are Network Interfaces, Logical Networks.

Try this command to delete the network: az network vnet delete --name <NetworkName> --resource-group <ResourceGroupName>

Please try this Azure CLI commands to delete Network Interface: https://learn.microsoft.com/en-us/cli/azure/azurestackhci/networkinterface?view=azure-cli-latest#az-azurestackhci-networkinterface-delete

If you still find any difficulties, please let me know I would like to work closer on this issue.

Hello Tang, Ken

This is common issue where the network is still in use by other resources, even after clearing out connections and interfaces.

Try to delete it by az cli command

az azurestackhci networkinterface delete --name "test-nic" --resource-group "test-rg"

All Network interface has been clear-out , only left the logical network, which can't remove.

Hi Tang, Ken,

Thanks for getting back, once check if there are any dependencies on the logical Network:

az azurestackhci logicalnetwork show --name <LogicalNetworkName> --resource-group <ResourceGroupName>

Check for Azure Stack HCI logs or event logs for any specific details on why the deletion is being blocked.

Try to force delete: az azurestackhci logicalnetwork delete --name <LogicalNetworkName> --resource-group <ResourceGroupName> --yes

Try to Restart Azure Stack HCI Services and then delete Logical Network.

If you still find difficulties, please let me know. Please provide any error message or screenshot of it.

Hi Anashetty,

I have run the command "az stack-hci-vm network lnet show " which show 2 NIC still attached on the "IPConfigurationReference" which has been deleted few days ago.

When i access to Azure portal, the Logical Network shows no network device connected to it.

DO you have any idea how to detach it ?

Hi Tang, Ken,

If the NIC appears in the 'IPConfigurationReference' but not in the portal, it might be a stale reference. Try force deleting it: az network nic delete --ids <nic-resource-id> Replace '<nic-resource-id>' with the full resource ID of the NIC, which you can get from the 'az network nic list' command.

First list all NICs with Resource IDs then identify stale NICs and delete them. Next verify if Logical network is free of dependencies. If the 'IPConfigurationReference' is empty you can delete logical Network.

Thank you

Hi Tang, Ken,

Check that there are no dependencies to the NIC: az resource show --ids <nic-resource-id> If there are any dependencies linked to the NIC, remove them and try deleting NIC.

You can also force delete via Rest API, by using Azure resource explorer navigate to NIC then delete it directly.
