You need to read the RFC for TCP/IP over SCSI transport, which covers this. > have to have an adapter that supports 'target mode' correctly. NO, sorry, but the adaptors usually *do*, as it's built into the chipsets (otherwise how would your SCSI disks work as targets? ;^). As usual, it's the **host software** that doesn't. Even then, if you are using the ASPI generalisation layer provided/sold by Adaptec, a lot of what you need for target mode is in there. Don't generalise, please.
