Unable to Delete NIC and osDisk After Failed Resource Move Between Subscriptions

Wiecek, Jaroslaw 20

I attempted to move a resource group between subscriptions that contained a VM (along with NSG, osDisk, NIC, and public IP) and virtual network resources. The VM was not powered off prior to the move, leading to an error during the operation. As a result, the VM remained in the old subscription while the other resources were transferred to the new one.

After facing issues with the VM, which could not be powered off, I deleted it. However, the NIC and osDisk remain in the new subscription as they are still linked to the deleted VM.

Is there a way to delete the osDisk and NIC?

Hi Wiecek, Jaroslaw,

Thanks for reaching out to Microsoft Q&A.

Pleaser follow below steps:

check for dependencies. NIC might be associated with public ip or NSG which needs to be deleted. Detach NSG and delete Public IP from portal.

Locate the OS disk on portal, ensure that there are no locks or snapshots associatd with disk. You can navigate to snapshots and check if those are avaialble for this disk and delete them. Under disk settings, check locks and delete them.

Hi Shikha,

thank you for reaching out.

There are no locks or snapshots on osDisk resource, public IP and NSG has already been detached.

I am getting this errors:

for NIC:

In order to delete the network interface, it must be dissociated from the resource. To learn more, see aka.ms/deletenic.

This VM has been deleted and I cannot neither detach NIC nor osDisk from it. The problem is that this resources will be incurring costs for my Visual Studio subscription.

Hi Shikha,

thank you for reaching out.

I don't have any outstanding dependencies apart from VM that no longer exists (I successfully deleted NSG and Public IP). No locks on osDisk as well. Both NIC and osDisk give me errors connected with being attached to that VM.

Hi,

Try to force delete the VM and see if portal is getting updated after that

command- az vm delete --resource-group myResourceGroup --name myVM --force-deletion none

Hi,

the command in new sub goes through without any errors, like nothing happens. In old sub there is not even a RG left, so it gives errors. those resources still point to old sub when looking for this VM.

my advice is now to create a support ticket and work with support engineer with all details- https://ms.portal.azure.com/#view/Microsoft_Azure_Support/HelpAndSupportBlade/~/overview

Hello @Wiecek, Jaroslaw

We have noticed that you have rated an answer as not helpful. We appreciate your feedback and are committed to improving your experience with the Q&A.
Basically this is a scenario of inconsistencies for the resources that are deleted abruptly. Let's try to troubleshoot this issue.

For nic deletion, try this cmd

az network nic update --name <NIC-Name> --resource-group <Resource-Group-Name> --remove virtualMachine
If possible to delete the entire RG, try
Remove-AzResourceGroup -Name [RESOURCEGROUPNAME] –Force

I am also leaving you a private message if you would like to connect offline for the diagnosis of this issue.

Issue Definition: Unable to Delete NIC and osDisk After Failed Resource Move Between Subscriptions

Cause : The VM was not powered off prior to the move, leading to an error during the operation. As a result, the VM remained in the old subscription while the other resources were transferred to the new one. Deletion of these resources in the attempt of cleanup, it landed in stale entries, broken links in the backend.

Error Message:
For Nic deletion-

Remove-AzNetworkInterface: Network Interface /subscriptions/<Sub_ID>/resourceGroups/<RG_name>/providers/Microsoft.Network/networkInterfaces/<NIC_name> is used by existing resource /subscriptions/<Sub_ID>/resourceGroups/<RG_name>/providers/Microsoft.Compute/virtualMachines/<VM_name>. In order to delete the network interface, it must be dissociated from the resource. To learn more, see aka.ms/deletenic.
StatusCode: 400 ReasonPhrase: Bad Request ErrorCode: NicInUse

ErrorMessage: Network Interface /subscriptions/<Sub_ID>/resourceGroups/<RG_name>/providers/Microsoft.Network/networkInterfaces/<NIC_name> is used by existing resource /subscriptions/<Sub_ID>/resourceGroups/<RG_name>/providers/Microsoft.Compute/virtualMachines/<VM_name>. In order to delete the network interface, it must be dissociated from the resource. To learn more, see aka.ms/deletenic.

for osDisk deletion-

Remove-AzDisk -ResourceGroupName <RG_name> -DiskName <Disk_name> -Force

Remove-AzDisk: Disk <Disk_name> is attached to VM /subscriptions/<Sub_ID>/resourceGroups/<RG_name>/providers/Microsoft.Compute/virtualMachines/<VM_name>.

ErrorCode: OperationNotAllowed

ErrorMessage: Disk <Disk_name> is attached to VM /subscriptions/<Sub_ID>/resourceGroups/<RG_name>/providers/Microsoft.Compute/virtualMachines/<VM_name>.

StatusCode: 409 ReasonPhrase: Conflict

Resolution:

In a scenario like this where the resource deletion fails due to the failure in complete resource migration resulting in the stale entries, users won't be able to force delete those resources like Nic/OSdisk etc., due to broken links or stale entries. Azure product team fixed this in the backend in order to remove those resources.
