This is the relative name (RN) -- the final naming component appended to its parent's DN -- that distinguishes one individual task queued as part of a chassis's finite-state-machine workflow from its siblings under the same parent object. Reading the RN alongside the parent DN is how UCS Manager, and any SNMP poller querying it, reconstructs which chassis FSM task a given row of data actually belongs to without repeating the full path in every field. For a chassis FSM task the RN is typically the last path segment shown in 'sys/chassis-3/fsm/task-1', e.g. 'task-1'.
