Introduction

FreeBSD doesn't enable target mode support for QLogic cards, so we need to compile a custom kernel. We'll assume we have installed a release and we have a populated /usr/src.

Create the kernel configuration file

cat <<EOF >/tmp/FCTARGET
include GENERIC
ident FCTARGET

options ISP_TARGET_MODE
EOF
sudo install -g staff -o aram /tmp/FCTARGET /usr/src/sys/amd64/conf

Create /etc/make.conf

cat <<EOF >/tmp/make.conf
# Build and install only FCTARGET kernel.
# /boot/GENERIC will be updated by freebsd-update(8).
KERNCONF=FCTARGET
sudo install -g staff -o aram /tmp/make.conf /etc

Create /usr/obj

Assuming you have ZFS:

sudo zfs create zroot/usr/obj
sudo chown aram:staff /usr/obj

Make a copy of GENERIC kernel

sudo cp -pr /boot/kernel /boot/GENERIC

From now on freebsd-update(8) will update this kernel.

Build and install the kernels

Build the kernel:

cd /usr/src
# builds FCTARGET
make buildkernel -j24

Install the kernel:

# installs FCTARGET
sudo make -j24 installkernel

If you need to rebuild GENERIC for whatever reason:

make buildkernel -j24 KERNCONF=GENERIC
sudo make -j24 installkernel KERNCONF=GENERIC INSTKERNNAME=GENERIC

Load isp(4) driver in /etc/loader.conf

As root:

sudo su -
echo isp_load="YES" >> /boot/loader.conf
echo ispfw_load="YES" >> /boot/loader.conf

Reboot and test

sudo reboot
