Can't you boot an instance without cinder? You could edit nova.conf to  
use local file system, just to have a running instance. If that works  
you can switch to another backend.

cinder create --image <IMAGE-ID> --name <NAME> <SIZE>

Try debugging your iscsi connection, maybe first without openstack. If  
you aren't able to login to a session then openstack will also fail, I  
guess...

In my environment, I first tried to get all services running and  
working without external backends, cinder, glance and nova all ran on  
local storage. Then I tried other backends for cinder (iscsi), now all  
services use ceph.
