/DEVICE_ALIAS=alias
       /NODEVICE_ALIAS (default)

    This qualifier selects the device name alias to be used for
    references to a directly-accessed partition file; for direct
    access to a partition file. The specified string will be the
    device name for subsequent accesses.

    The permissible character set for this string is that of devices;
    the same symbol character set used for logical names. Like a
    logical name, there is no requirement to mimic the OpenVMS device
    name fields.

    The specified alias must include a trailing colon.
