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.
