This enumerated value (CucsEquipmentMemoryUnitDiscoveryModifierAction) states what action the discovery-modifier rule takes against the memory part it targets — for instance exempting it from a check or forcing a particular classification. Which action is set determines whether an admin sees a previously-blocked DIMM suddenly accepted, or an otherwise-accepted DIMM suddenly flagged, after a capability-catalog update introduces or changes this specific rule. A value corresponding to 'exclude' would mean this rule tells UCS Manager to skip its normal discovery checks entirely for the targeted DIMM part.
