This object holds the actual raw identifier value for this discovered LUN, whose format is entirely determined by the three companion objects that describe its code set, association, and type, per the desc. An admin or automated tool trying to uniquely and persistently identify a specific LUN across reboots or path changes - for reliable inventory matching - relies on this identifier value (correctly decoded using its companions) rather than the more volatile LUN number in ciscoScsiDscLunLun. A value decoded as a standard NAA identifier here would give the admin a stable handle on that LUN even if its numeric LUN address changed after a reconfiguration.
