This is the relative name (rn) of the FSM task, per its ChassisProfileFsmTask rn property — the last arc of the dn naming this task's own position under its parent stage. Because the rn is the short, recognizable segment (unlike the full dn), it's the piece an admin actually reads at a glance in a UCS Manager FSM log entry for chassis-profile-association tasks. An rn like 'fsm-task-1' combined with its parent stage tells you this is the first task Manager kicked off for that stage, e.g. issuing the IOM discovery request.
