MPIO_PATH_INFORMATION WMI Class

A WMI client uses the MPIO_PATH_INFORMATION WMI class to query the MPIO driver for information regarding all paths that are associated with an MPIO disk.

class MPIO_PATH_INFORMATION
{

    [key, read]
     string InstanceName;
    [read] boolean Active;

    //
    // Number of paths to the device.
    //
    [WmiDataId(1),
     read,
     Description("Number of Paths in use") : amended
    ] uint32 NumberPaths;

    //
    // Pad for data alignment.
    //
    [WmiDataId(2),
     read,
     Description("Pad for ULONGLONG Alignment.") : amended
    ] uint32 Pad;

    //
    // Array containing each path's information.
    // Note that each of these are ULONGLONG aligned.
    //
    [WmiDataId(3),
     read,
     Description("Array of Adapter/Path Information.") : amended,
     WmiSizeIs("NumberPaths")
    ] MPIO_ADAPTER_INFORMATION PathList[];

};
