[in] PVOID HwDeviceExtension,
[in] ULONG NodeNumber,
[out] PGROUP_AFFINITY NodeAffinityMask
);
[in] HwDeviceExtension
A pointer to the hardware device extension for the host bus adapter (HBA).
[in] NodeNumber
The NUMA node from which to return the processor mask.
[out] NodeAffinityMask
A pointer to a variable that holds the affinity mask of the given node.
The StorPortGetNodeAffinityroutine returns one of the following status codes:
