This is the Relative Name (Rn) of the automatic core-file export target, the remote destination UCSM is configured to upload process core-dump files to automatically after a crash, the naming component that distinguishes this instance from its sibling AutoCoreFileExportTarget objects under the same parent in the UCS tree. Admins rarely read the Rn directly, but UCSM uses it to build the full Dn path, so it matters when correlating which parent object a given AutoCoreFileExportTarget instance belongs to. For instance, if two AutoCoreFileExportTarget objects sit under the same parent container, their Rn values are what tell UCSM (and any script parsing the Dn) apart which one is which.
