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.
