We do both! QLogic ships each card with some version of the firmware on it that boots up at runtime. One of the nice features of the ISP is that its RISC based firmware can be updated at runtime ensuring you are always running the latest. The ispfw driver is strictly used to register firmwares with the generic firmware driver (the real action happens in isp during isp_reset()). I think the driver should really check to see if the ispfw version is less than the resident driver and do the right thing. I think it used to do that but was taken out, I don't know why - I'm actually thinking of maybe it should be added back. In any event, if you want to disable loading of the firmware you can set in your hints file: hint.isp.0.fwload_disable=1 That should prevent the driver from loading the ispfw version (please check during bootup what version your resident firmware is at to determine which is newer). If you do this then you should see: isp0: Board Type 2300, Chip Revision 0x1, resident F/W Revision <version string> instead of isp0: Board Type 2300, Chip Revision 0x1, loaded F/W Revision <version string> Having a separate utility (typically DOS or Windows based) is not that great in my eyes but to each his own. Bottom line is you should run the latest ISP firmware (whether its the one that was flashed from QLogic or the one in the ispfw driver). I'm thinking that perhaps and audit should be done and we should ship the latest firmware off the QLogic website. What version is shipped with your card? Looks like 3.3.25 is the latest for 23xx cards. Hmmm.... > I misunderstood the purpose of your patch as well.

I noticed its not trying to get isp_2300_it like before (I'm hoping that's due to the patch I sent otherwise I'm confused this holiday weekend). > Here's the complete kernel, also after a fresh install and the removal of > unnecessary options/devices (stuff not in the server): > # SCSI Controllers > device isp # Qlogic family > device ispfw # Firmware for QLogic HBAs- normally a > module > options ISP_TARGET_MODE # for ISP cards to operate in target mode > device targ # SCSI Target device > device targbh # SCSI Target Black Hole > options CAMDEBUG > options VFS_AIO Thanks for this, I just wanted to verify your build options look good. > Not sure what to make of this.... Would you recommend a different FC card? > Emulex? I have no direct experience with Emulex with FreeBSD so I'm not the right person to ask. I was under the impression that the 23xx target mode was working. Did you enable target mode in the BIOS by chance (or disable it, I think on my 24xx BIOS I have that option but I'm not in front of it yet). Just verify your BIOS version number and options before completely giving up! :D -aps
