<Exactly. Some controllers know, and assert events up to their LLDD. <Jame's Emulex driver apparently does, perhaps this holds true for all <FC devices.
<Some firmwares (LSI megaraid for sure, Adaptec SCSI I believe) don't. Thank you, Matt. Then I have another question: As we know SCSI mid-layer issue a command to LLDD by host->hostt->queuecommand(cmd, scsi_done); and in the meantime a timer is set. When the timer expires, SCSI mid-layer know the execution of command has failed. My question is: when SCSI device is surprise-removed, if SCSI mid-layer issue a command to this removed device, will mid-layer has to wait a timeout before it can know the execution of command failed? Or is there any other mechanism that LLDD can notify mid-layer that execution of command failed without waiting for a timeout?
