def retrieve_tape_archive(TapeARN=None, GatewayARN=None):
    """
    Retrieves an archived virtual tape from the virtual tape shelf (VTS) to a tape gateway. Virtual tapes archived in the VTS are not associated with any gateway. However after a tape is retrieved, it is associated with a gateway, even though it is also listed in the VTS, that is, archive. This operation is only supported in the tape gateway architecture.
    Once a tape is successfully retrieved to a gateway, it cannot be retrieved again to another gateway. You must archive the tape again before you can retrieve it to another gateway. This operation is only supported in the tape gateway architecture.
