This is the relative name distinguishing this individual task row from any sibling tasks spawned by the same stage of the IfFsmTask workflow. For a physical or logical management network interface (for example mgmt0 on a fabric interconnect, a CIMC, or an I/O module), task Rns are what let UCS Manager track several simultaneous remote sub-calls issued by one stage of bringing that management interface up or pushing a new IP/VLAN configuration down to it without conflating their results. A typical value looks like 'task-1'.
