[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: iSCSI: DLB-T.26 (response for TASK REASSIGN)Julian, I don't want to make an issue of it, but IMHO, since the Task Reassign TMF causes two task instances in target to go active (the TMF itself, and the reassigned task), it's best to describe the order of status delivery in the TMF discussion itself - i.e. 9.6. It's easy to miss if described elsewhere.
