This OID gives the Relative Name (RN) of an auto-discovered iSCSI target interface that an iSCSI vNIC picked up via DHCP/iSCSI-boot-firmware-table discovery rather than manual entry — the naming component that distinguishes this particular IScsiAutoTargetIf instance from its sibling instances under the same parent object. Because RNs are combined with a parent DN to build the full path, an admin uses this value to understand how UCS Manager names and organizes multiple IScsiAutoTargetIf entries that exist under the same vNIC or service profile. For example, if two IScsiAutoTargetIf entries exist side by side, comparing their RNs is how an admin tells them apart when the parent DN alone is identical for both.
