This holds the rn — the Relative Name — of the record identifying which hardware or firmware component — BIOS, CIMC, or adapter firmware — is the actual source of a given family of POST codes; it is only the final path segment identifying this object relative to its immediate parent, not the whole dn. Because a POST-code reporter identity record is nested under a parent object in UCS Manager's tree, the rn is what distinguishes it from sibling entries under that same parent without repeating the full ancestor path every time. For an object whose dn is 'capabilities/post-code-reporter-1', the rn would just be the trailing segment 'post-code-reporter-1'.
