This is the Relative Name (RN), a read-only string that distinguishes one instance of a contiguous block/range of UUID suffix values reserved within a UUID pool 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 an administrator carves out a specific range of UUIDs for one group of blade servers, comparing RNs lets an admin tell apart two sibling objects of this same class that share the same parent.
