Justin,
I just tried to build a kernel with these patches. We seem to be

I am currently working on a software SCSI emulator for FreeBSD. I
was wondering if anybody knows if there's any signifigant differences
between the T10 groups final working drafts, which are free on their web
site, and the final ANSI standards, which cost upwards of $100 a pop.
Thanks,
Alex

I think they're pretty close, but you'd have to ask someone who has
actually compared the drafts to the standards to be sure. :)
FWIW, we have used the drafts for the CAM development, and I don't think
we've run into any issues caused by a draft/standard difference.
What sort of emulator are you working on? Is this a SCSI target emulator,
i.e. something that is supposed to act like a disk or a tape drive? Or is
this some other sort of emulator?
A well written disk emulator (or tape emulator) could be a valuable
contribution to FreeBSD. You could use a disk emulator to do things like
form the basis of a FreeBSD-hosted software RAID array, or to test error
recovery code.

A SCSI-3 target mode disk emulator. Our group is aiming to build an
extremely reliable 80-node cluster. Unfortunately, its difficult to test the
fault-tolerance of our SCSI adapters or drivers when the only things you can
do to a scsi drive to inject faults is to unplug it or shake it :) The group
already owns a commercial product that runs under NT, but the process of
interjecting faults crashes the NT system that pretending to be the drive!
I hope to fix up some of the target mode code in the Adaptec 71xxx driver,
and then make a user mode SCSI parser with either a command line or GUI (if I
have time) interface that allows me to inject repeatable faults. My intention
is to open the code and invite other people to contribute, but I'll have to
cross that bridge when I get to it (all the IP belongs to UC Berkeley, not the
lowly undergrad that writes it).
Justin Gibbs has already been very helpful. If anybody else has
suggestions, please PLEASE let me know. I can use all the help I can get.
Thanks, guys.
-Alex
