This is the Relative Name (RN), a read-only string that distinguishes one instance of the container object representing the complete set of UUID pools defined in this UCS domain 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 tool needs a single top-level reference point to enumerate every UUID pool that exists, comparing RNs lets an admin tell apart two sibling objects of this same class that share the same parent.
