Unable to change VM Size D2ds_v5 to D2ds_v6

Question

Hi,

I try to change the size of a vm in Germany West Central from Standard_D2ds_v5 to Standard_D2ds_v6. But I receive the following error:

Update-AzVM: Unable to resize the VM 'VMNAME' since changing from resource disk to non-resource disk VM size and vice-versa is not allowed. Please refer to https://aka.ms/AAah4sj for more details.

ErrorCode: OperationNotAllowed

ErrorMessage: Unable to resize the VM 'RemotePC01' since changing from resource disk to non-resource disk VM size and vice-versa is not allowed. Please refer to https://aka.ms/AAah4sj for more details.

ErrorTarget:

StatusCode: 409

ReasonPhrase:

OperationID : 520a14a5-3379-4255-bd97-6b5fa84bbe73

I don't know why. Because I change from an size with temp disk to an vm size also with an temp disk.

Could you help me?

Hello Sean, Welcome to MS Q&A

The error you're encountering when trying to change the VM size from Standard_D2ds_v5 to Standard_D2ds_v6 in Germany West Central is due to the restriction on changing from a VM size with a resource disk to one without, and vice-versa. This is a common limitation in Azure when dealing with VM size changes.

To resolve this, you should check if the Standard_D2ds_v6 size is supported in the Germany West Central region and ensure that you have the necessary quotas available for that size. You might need to consider resizing to a different VM size that doesn't have this restriction or create a new VM with the desired size and migrate your workloads.
