This is the overall status of the state machine driving this object's asynchronous workflow, expressed as short text rather than a numeric code. Deleting a QoS definition isn't instantaneous — UCS Manager has to unwind every reference to it on every fabric interconnect and adapter that used it, and this task object is what tracks that cleanup to completion. Typical values include 'nop' when nothing is in progress, or a stage name concatenated with a completion word once UCS Manager finishes pushing the QoS change to every fabric interconnect.
