+Subject: Initialize path state to be passive when path is not owned
+From: Chandra Seetharaman <sekharan@us.ibm.com>
+Date: Thu Nov 20 14:14:39 2008 +0100:
+References: bnc#442676
+
+Set the path state to be passive when we learn that the controller does
+not own the path to the LUN.
+
+This will avoid sending even a single i/o thru the passive path at the
+probe time.
