device-name

    Specifies a physical device name or a logical name equated to
    a physical device name. Specify the device name as a character
    string expression.

    After the device-name argument is evaluated, the F$GETDVI
    function examines the first character of the name. If the
    first character is an underscore (_),  the name is considered
    a physical device name; otherwise, a single level of logical name
    translation is performed and the equivalence name, if any, is
    used.

 item

    Specifies the type of device information to be returned. The
    item must be specified as a character string expression. You
    can specify any one of the items listed below. For detailed
    descriptions of each item code, see the HP OpenVMS DCL
    Dictionary.

    Items marked with a ** are valid for Integrity servers only.

    Items marked with a * are valid for Alpha and Integrity servers
    only.

    Items marked with a + are typically used with the pathname
    argument.

 pathname (Alpha/Integrity servers only)

    Specifies a path name for a multipath-capable device. Specify the
    path name as a character string expression.

    Item codes that use the pathname argument are identified by
    a + in the item code list. In general, item codes that return
    information that can vary by path do use the pathname argument.
    You can see the paths for a multipath device by using the SHOW
    DEVICE /FULL command, the SYS$DEVICE_PATH_SCAN system service, or
    the F$MULTIPATH lexical function.

    If the pathname argument is specified, it is validated against
    the existing paths for the specified device. If the path does not
    exist, the NOSUCHPATH error is returned - even if the specified
    item code does not make use of the pathname argument.
