Unknown Properties

An unknown property is a private property that is not defined by the cluster software or by a resource DLL. Unknown properties cannot be read-only and cannot be required. Currently, any private property defined for a group, network, network interface, or node is an unknown property. A private property defined for a resource or resource type outside of the resource DLL that implements the resource type is also an unknown property.

Resource DLLs use the Cluster Utility Functions to work with unknown properties, specifically ResUtilAddUnknownProperties, ResUtilGetAllProperties, and ResUtilSetUnknownProperties.
