This OID returns the Relative Name (RN) of a Fibre Channel logical interface — the short naming component, carried as a short text string, that distinguishes this Fibre Channel logical interface instance from its sibling instances under the same parent object. Admins rarely read the RN directly, but UCS Manager uses it internally to keep multiple Fibre Channel logical interface objects under the same parent (for example several on one server) from colliding in the naming tree. For instance, if a server has two Fibre Channel logical interface objects side by side, each will carry a different RN suffix even though their parent DN prefix is identical, letting the RN alone tell them apart.
