What's your issue about this, per se? Well, the driver for asking was my management asking if FreeBSD supported this, as we're going to do it on AIX (with the Dual Pathing Option) and with Solaris (running Veritas which I need to investigate more). We're reasonably big on redundancy here and we're running a number of critical systems on FreeBSD (DNS, WINS, DHCP, primary webserver, PDF server, etc). > Right now there's no framework code to directly exploit or prohibit multiple > paths to the same disk, whether via Fibre Channel or SCSI. Ok, but I suspect it would get a trifle upset if I started duplicating LUNS. :) I really don't know how much work this would be but would be interested in helping. I'm not a kernel hacker but I can offer testing resources (well, in about a month or so when the box arrives) for SCSI and possibly Fibre Channel if someone has code. Carl.
