This object reports the name assigned to this target port for use in the SCSI protocol, in the transport-appropriate format (typically a WWN for Fibre Channel). An admin building a port-level inventory of a storage array's front-end ports uses this name to identify each physical port distinctly in reports and dashboards, matching it against what is configured in fabric zoning for that array. A port showing a WWN not present in any zone configuration would indicate an unzoned, effectively unused port on that array.
