I've run into a snag with our SAN and I'm hoping someone out there can shed some light on the glass, as it were. We're trying to use scsi_target mode with a pair of QLogic ISP2310 2GB fibre-channel cards in a Point-to-Point topology. These cards will NOT be part of a switch fabric. I started out with a quad port card, and when I rescanned the SCSI bus on the initiating end of the loop, the target machine tanked. The filer dumps core, reboots, and reproduces the result faithfully. Thinking I might be doing something wrong with port selection, I pulled the quad port card out of the SAN filer and installed a single port card. After several days of jiggery pokery with all manner of knobs, AIO, etc, I've ended up with the same result: a 64-bit space heater. :) I've Googled this to death, crawled the lists, and I've not found a solution other than the occasional "it might be buggy" comment. Full kernel traces are available to anyone interested, possibly even ssh access to a test box if requested. I've been running FreeBSD for about 7 years and I've never seen an operating system as stable, so I'm rather determined to make this work than go to Linux. The filer is running FreeBSD 7.0 amd64, dual Opteron 2216's, with 8 gigs of ram. I've tested this on a pair of HP DL580 G3's to see if there was a difference from 32-bit to 64-bit hardware, but none was apparent. Any help is greatly appreciated! -- Erich M.
