MPIO_DISK_INFO WMI Class

A WMI client uses the MPIO_DISK_INFO WMI class to query MPIO so that it gathers information regarding every MPIO disk that is configured in the system.


class MPIO_DISK_INFO
{
    [key, read]
     string InstanceName;
    [read] boolean Active;

    //
    // The Number of multi-path disk pdos that have been
    // created.
    //
    [WmiDataId(1),
     read,
     Description("Number of Multi-Path Drives.") : amended
    ] uint32 NumberDrives;

    //
    // Variable-length array of DRIVE_INFO structures.
    // NOTE: Each entry will be ULONG aligned. App. writers
    // take note when iterating through the array.
    //
    [WmiDataId(2),
     read,
     Description("Multi-Path Drive Info Array.") : amended,
     WmiSizeIs("NumberDrives")
    ] MPIO_DRIVE_INFO DriveInfo[];
};

When compiled by the WMI tool suite, this class definition produces the MPIO_DISK_INFO data structure. There are no methods associated with this WMI class.
