When you submit this command, you cannot specify an image mode VDisk that has a virtual medium error on the VDisk or on any copy of the VDisk because the medium errors cannot be maintained on the ejected MDisk image copy.
If an exact image copy is required, ensure that there is no virtual medium error on the image mode VDisk that you specify or on any of its copies, and resubmit the command.
If an exact copy is not required, you can use the -force option of the command, but all of the virtual medium errors will be lost.
