+	* Storage.pm (iscsi_login): login to target, instead of
+	portal -  to make it work when one portal is offline.
+
+	* Storage.pm (iscsi_test_portal): test if portal in online (use 2
+	seconds timeout).
+
+	* Storage.pm (iscsi_discovery): test if portal is online using
+	iscsi_test_portal(). This avoids that we run int a timeout (iscsi
+	default timeout is 15 seconds, we now use 2 seconds)
