If the enable was successful, you can expect... * * Response queue entries with SCSI commands encapsulate show up in an ATIO * (Accept Target IO) type- sometimes with enough info to stop the command at * this level. Ultimately the driver has to feed back to the f/w's request * queue a sequence of CTIOs (continue target I/O) that describe data to * be moved and/or status to be sent) and finally finishing with sending * to the f/w's response queue an ATIO which then completes the handshake * with the f/w for that command. There's a lot of variations on this theme, * including flags you can set in the CTIO for the Qlogic 2X00 fibre channel * cards that 'auto-replenish' the f/w's ATIO count, but this is the basic * gist of it. * * The third group that can show up in the response queue are Immediate * Notification events. These include things like notifications of SCSI bus * resets, or Bus Device Reset messages or other messages received. This * a classic oddbins area. It can get a little weird because you then turn * around and acknowledge the Immediate Notify by writing an entry onto the * request queue and then the f/w turns around and gives you an acknowledgement * to *your* acknowledgement on the response queue (the idea being to let * the f/w tell you when the event is *really* over I guess). * */ /* * A new response queue entry has arrived.
