Error: Set-AzureRmVMDiskEncryptionExtension : User encryption settings in the VM model are not supported. Please upgrade Azure Disk Encryption extension version and clear encryption settings in the VM model.

    Question

  • Hi,

    I'm trying to encrypt Azure VMs' disks. It is working well for some but I'm getting an error on some VM's. The command I run is 

    Set-AzureRmVMDiskEncryptionExtension

    And the error I get is:

    Set-AzureRmVMDiskEncryptionExtension : User encryption settings in the VM model are not supported. Please upgrade
    Azure Disk Encryption extension version and clear encryption settings in the VM model.
    ErrorCode: NotSupported

    extension version and clear encryption settings in the VM model.

    In one environment, I removed those VM's and recreated them so I didn't get an error after that but it sounds not a good practice since all VM's are the same. Now it happened again in other environment and I would like to understand why this happens for some VMs and it works for others.
