This is the Relative Name (RN), a read-only string that distinguishes one instance of the policy that controls whether this UCS domain's system information is kept synchronized with a managing system such as UCS Central from its sibling instances under the same parent container. Because UCS Manager builds each object's full DN by concatenating RNs down the management tree, this value is the local naming piece an admin needs to understand how the object is addressed relative to its parent. For example, when a UCS domain is registered with UCS Central and needs to keep its reported system info in sync, comparing RNs lets an admin tell apart two sibling objects of this same class that share the same parent.
