Hi all, (before leaving for holiday ...)
I'd like to attend LSF 2014. During that I'd like to discuss the current status of the SCSI EH and the future planned updates. As discussed during last year's LSF the SCSI error handler should be updated to handle modern SCSI transports better. While some patchsets are already merged, there are some issues which are still open: - Handling of requests during host reset: Do we need to keep hold of outstanding requests during host reset? Or is it save to return them prior to host reset? - Check for transport status prior to sending TMFs. Task management functions typically need a working I_T nexus, so it does make sense to first check the transport status prior to attempting any TMFs - Further steps for updating SCSI EH As these are tricky issues which have possible repercussions on the entire subsystem and LLDDs it'd be good to have a broader discussion here.
