We are revisiting the initiate negotiation question on our disk
products and we wanted to query the reflector audience for their
Currently, we DO NOT initiate synchronous negotiation since some
early host adapters didn't respond very well to the behavior. One
concern with this behavior is an adapter which doesn't re-negotiate on
check conditions status may result in a sync host with and Async target.
We do allow for target initiated negotiations to be enabled through
a mode page control bit, but it's defaulted off.
One proposal is to turn initiate on for wide negotiations based on
the argument that most (all?) wide adapters must be more advanced
and probably handle target initiated negotiations fine. Is this
a reasonable assumption? Do people know of drives which do initiate
negotiations by default?
