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[];
};
