MPIO_DEVINSTANCE_HEALTH_INFO WMI Class

An MPIO driver uses the MPIO_DEVINSTANCE_HEALTH_INFO WMI class to report health statistics of an MPIO disk by using underlying different paths.


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

    [WmiDataId(1),
     read,
     Description("Number of Health Packets.") : amended
    ] uint32 NumberDevInstancePackets;

    [WmiDataId(2),
     read,
     Description("Reserved for future use.") : amended
    ] uint32 Reserved;

    [WmiDataId(3),
     read,
     Description("Multi-Path Health Info Array.") : amended,
     WmiSizeIs("NumberDevInstancePackets")
    ] MPIO_DEVINSTANCE_HEALTH_CLASS DevInstanceHealthPackets[];
};

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