This is the Relative Name (RN), a read-only string that distinguishes one instance of a metadata record describing the schema/version information of the UCS management information tree itself 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 management application needs to confirm which management-model version a given UCS Manager instance is running, comparing RNs lets an admin tell apart two sibling objects of this same class that share the same parent.
