cucsProcessorQualRn is the read-only Relative Name that distinguishes one processor-qualification rule from its sibling qualifiers under the same parent policy in the UCS management tree. An admin cares because the Rn is what makes each qualifying rule (by architecture, core count, model, and so on) individually addressable when a server pool policy has multiple CPU criteria defined. For example, two Qual entries under the same pool policy would carry different Rns so UCS Manager can tell a min-cores rule apart from a max-speed rule.
