Julian,
I don't think it is
a misreading of the text. I will try restating the question.
You say below "the
barrier "stays" while the connection is operational and will be
"removed" if the connection goes away.
Does "the connection
goes away" mean that the connection state machine leaves S5: LOGGED_IN
state or does it mean that the connection state machine has returned to S1: FREE
state?
Pat
Pat,
Your "issue" with operational is probably related
to a missreading of the text.
The barrier (dissalow wrapping) is on CmdSN. CmdSN
advances accross al connections but the barrier "stays" while the
connection is operational and will be "removed" if the connection goes
away.
The barrier is there to avoid stale commands
popping-up at the target after a recovery.
