I have a question about actions taken by the initiator.
I suppose that if the target's agent finds this situation, target
enters from 'execute' state to 'abort all subsequent commands' state
(in order not to execute the commands still not fetched).
The initiator will wait until target aborts all subsequent commands
destined to the queue.
(Target may be executing commands destined to another queue at this
After all subsequent commands are aborted, the initiator will requeue
aborted commands with properly assigned sequence ids.
I think, initiator "needs to" restore target's agent state to
'execute' without affecting the execution of another queue at this
How does target find the initiator recovered from the
situation? (I may be misunderstanding the process.)
In the model I described in previous mails, the initiator does not
take recovery action at all.
Because descriptive explanation may make it hard to be well
understood, I am preparing some slides for explanation.
Ueda-san from Canon will make a presentation for this alternative
model at upcoming Toronto meeting.
