Actually, SCSI was intended to do things like this. All devices on a SCSI bus are peers. Any device can initiate a command to any available target. You are allowed multiple targets and multiple initiators. The fact that most people use a single host attached to a bunch of "dumb" devices is incidental. If you think of a SCSI-to-SCSI RAID controller, you have a perfect example of a smart device acting as a SCSI target. The limitations we encounter here are mostly in Linux. The Linux kernel's SCSI subsystem has long been a broken mess. My understanding is that things were improved somewhat for 2.4, but a total rewrite is still needed. So the core SCSI code, and the device drivers, simply do not support this kind of operation. Additionally, many SCSI host adapters (either firmware or silicon) do not implement target mode, or do so poorly. -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do not | | necessarily represent the views or policy of any other person, entity or | | organization.
