This is the Relative Name (RN) of a single recorded configuration error UCS Manager logged while applying a policy, the single naming component that distinguishes this ConfigError instance from its sibling instances under the same parent object. UCS Manager appends this RN to the parent's DN to build the full path, so it is the piece an admin checks when several ConfigError instances exist side by side and need to be told apart, because its code, description, and location pinpoint exactly what configuration step failed and where. For a failed service-profile policy push that left behind an error record, if two ConfigError instances share the same parent, this RN is the one field that tells an admin which of the two a given SNMP row is actually describing.
