Ok. It dissapear when I upgraded my system.

As I have lvm in iscsi volume, I had to patch lvm init.d stop script (see my
no-answered question athttp://
www.redhat.com/archives/linux-lvm/2009-February/msg00003.html and
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=498616) (else, my reboot
hangs).

But this change (add vgchange --available=n $vg || RETVAL=1 at stop function
in /etc/init.d/open-iscsi ) made my upgrade hang (I had to manually kill the
proccess, umount my partitions on iscsi and follow with the installation)

So in my logs:

First ISCSI start (and tells connection 5-8 are operationals):

I tried,
# multipathd -k'reconfigure'
OK

But syslog is growing like before

Should I ask to iscsi list then ?

Thank you very much
