Remarks
On a dynamically partitionable server that is running Windows Server 2008 or later versions of Windows Server, the operating system initiates a system-wide resource rebalance whenever a new processor is dynamically added to the system. The device class participates in resource rebalancing under the following circumstances:
The DEVPKEY_DeviceClass_DHPRebalanceOptOut device property does not exist.
The device property exists and the value of the device property is not set.
The device property exists and the value of the device property is set to FALSE.
If the DEVPKEY_DeviceClass_DHPRebalanceOptOut device property exists and the value of the property is set to TRUE, the device class does not participate in resource rebalancing when a new processor is dynamically added to the system.
A device's device setup class is specified in the INF Version Section of the device's INF file.
The default value for this property for the Network Adapter (Class = Net) is TRUE. The default value for this property for all other device setup classes is FALSE.
This device property does not affect whether a device class participates in a resource rebalance that is initiated for other reasons.
You can access the DEVPKEY_DeviceClass_DHPRebalanceOptOut property by calling CM_Get_Class_Property or SetupDiGetClassProperty and CM_Set_Class_Property or SetupDiSetClassProperty.
