              <div>Hello,<br>
                I am experiencing an issue with on my current ovirt DC.<br>
                The setup is 2 machines running Ovit Nodes connected to
                a LaCie 12big Rack Fibre 8, the nodes are connected to
                both controllers.. This configuration has worked fine
                for a couple of weeks.<br>
                <br>
              </div>
              Recently the nodes go from Up status to Non Operational.
              When I activate them back they don't last more than 2
              minutes.<br>
              <br>
              <br>
              /var/logl/messages on both nodes shows the same errors : <br>
