This is a bitmask of internal behavior flags UCS Manager attaches to this spawned task, controlling things like whether it should be retried automatically. Each stage of the deletion state machine hands its actual work off to an internal UCS Manager task, and this object is the record of that specific spawned task. This is an internal value an admin doesn't set directly; seeing an unusual combination of bits here is mainly useful to Cisco TAC when diagnosing why a task behaved unexpectedly.
