target mode/ISP

[Andy White]

I am running freebsd 5.1 release with an Adaptec 2940u2b and Qlogic 2300f fibre card. I want to connect to the internal scsi drives over fibre channel with the Qlogic card. Is this possible to do? 

We envision that by running the scsi target mode and emulating the disk drives we could then use that virtual drive for our fibre channel clients. If this is possible, on what device does target mode need to be enabled or does it need to be enabled on both? I have followed the instruction from Nate on this website http://www.root.org/~nate/freebsd/README.targcompiled 

Compiled kernel with both devices in target mode and ran the command ./scsi_target 1:0:0 w/ my target file and for a sec it appeared to be working however gave me an error about 16 devices but starting anyway. It appeared in the backgroup as running however the other fibre channel clients could not see it as a device.  I reset the box a few minuets later and now just get error on the screen

isp0: Mailbox Command 'SEND SNS' failed (error 0x400a)

isp0: SNS Failed- timeout or transmit failed

isp0: Mbox Command Async (0x4005) with no waiters

Lastly does anyone know where I find some good documentation on how all this works? Any ideas or comments would be greatly appreciated. Thanks.
