I compiled just the iscsi initiator this evening and remembered this thread, so
here are the simple instructions. This is not the "right" way to do it.
It's just the easiest. I should (and probably will) use a Makefile for this,
but for now, this works and I've been able to tweak some of the timeouts in my
system. Tests are still running, so I have no results on whether it's a good
idea or not yet.
# Check out all of ONNV (mercurial does not have partial checkouts AFAIK)
hg clone -U ssh://a...@hg.opensolaris.org/hg/onnv/onnv-gate
# go into the iscsi initiator directory
cd onnv-gate/usr/src/uts/common/io/scsi/adapters/iscsi
# edit your files
vim iscsi.h
# compile!
PATH=/opt/SunStudioExpress/bin:/usr/ccs/bin:$PATH
export PATH
for cfile in *.c ../../../../../../common/iscsi/*.c
../../../../inet/kifconf/kifconf.c
do
cc -I. -I../../../.. -D_KERNEL -D_SYSCALL32 -m64 -xO3 -xmodel=kernel
-c $cfile
done
ld -m64 -dy -r -N misc/scsi -N fs/sockfs -N sys/doorfs -N misc/md5 -N
inet/kifconf -o iscsi *.o
# back up the default driver
cp /kernel/drv/amd64/iscsi /root/iscsi.bak
# install
cp iscsi /kernel/drv/amd64/iscsi
# if you want to avoid reboot, shut down iscsi_initiator
update_drv iscsi
# reboot if necessary - I prefer to "zfs export" and "rm -f /etc/iscsi/*"
before doing so in my lab
There was a bit more that went into this when I did it, but that should get you
far enough to play with timeouts. Be sure to check out elfdump(1). It
can tell you a lot about your new driver -- it's how I verified I got all the
right bits in my build before I tried it in the kernel for the first time.
