This is driving me nuts! Does anyone know if this is a bug, or am I
doing something wrong?
I searched the RHEL bug list, but can't find anything related to this.
Some other people (via google search) seems to have simila problems,
but I can't see any fixes on the web.
I can logout out of all sessions, but as soon as I restart iscsi, the
sessions gets restored again:

So, iscsi logs out of the targets, and fdisk -l confirms it:
[root at localhost ~]# fdisk -l
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders

/dev/sdb1 * 1 13 104391 83 Linux
/dev/sdb2 14 121584 976519057+ 8e Linux LVM
But as soon as I restart iscsi, it logs back-in:
[root at localhost ~]# /etc/init.d/iscsi restart

Why?
Or, how do I completely get rid of them?
