We're probably going to use Nate Lawson's target mode driver. From my reading of the relevant scsi documentation, it seems like the target's scsi interface has to know the length of a command from the opcode so it will know when the command phase finishes. Is this in fact the case? If so, what will e.g. a Qlogic ISP in target mode do with vendor-specific commands? thanks john To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
