This is the Relative Name (RN), a read-only string that distinguishes one instance of an object capable of drawing its UUID from a UUID pool rather than having one hard-coded 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 service profile template is configured to obtain its UUID dynamically from a pool at association time, comparing RNs lets an admin tell apart two sibling objects of this same class that share the same parent.
