This OID holds the Relative Name (Rn) of a discovery policy object — the single naming component that, appended to its parent's DN, distinguishes this discovery policy instance from its sibling instances under the same parent. Monitoring software combines this Rn with the parent path to reconstruct the object's full DN, which matters when several discovery policy instances exist side by side under the same UCS container. For example, when cucsPolicyDiscoveryRn returns a short token such as "discovery", that token is concatenated onto the parent's DN to form the complete address used elsewhere in the MIB for this discovery policy instance.
