This OID gives the Relative Name (RN) of the iSCSI vNIC address/pool configuration object that controls where an iSCSI boot vNIC's IP and IQN addressing comes from — the naming component that distinguishes this particular IScsiConfig 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 IScsiConfig entries that exist under the same vNIC or service profile. For example, if two IScsiConfig entries exist side by side, comparing their RNs is how an admin tells them apart when the parent DN alone is identical for both.
