Fair question. The "icscictl -L" and also netstat lists one of the pool
addresses not the initial and configured address.

So my client with, lets say, address has the address e.g. in his iscsi.conf but will than connect to one of the pool IPs - on port 3260

It works just fine with the VMware vSphere hosts... :/
