Looks like a startup sequence problem, it could be that / is still mounted
readonly, but I do not see how that happens, as /etc/rc.d/iscsid should
be pretty late in the startup phase.   Are you trying to run with a
readonly root filesystem?

Since you dont really need iscsid until you go to mount additional file
systems maybe it can be moved to a later start up phase.  Argh, you trying
to swap to it, hum, that is going to be a "new file system" and would
need iscsid to setup the connection.

What does "services -e" show for a startup sequence.
What does your /etc/fstab look like.

Thats odd, how did it get created if the open failed.
Can you stop iscsid/iscsictl,
rm /var/run/iscsid.pid and do a reboot, see if it comes back
do not start anything manually I want to know if an empty
file really is being created during boot?

What is in your /etc/iscsictl.conf file, your asking for All
sessions in it to be added here, I am assuming that is /home?
