Re: Initiator-detected format or digest errors

Matt,

3 reasons:

a. the initiator drives recovery. What can a target do with the reject?
(he is probaly in need of a reset)

b.the initiator is unaware of the target state after thhe error

c.there is reject command (and response) -:)

Why not send a reject back to the originator of the bad frame, and just let
the task time out?
