Subject: [PATCH]: scsi_dh: Initialize path state to be passive when path is not owned
Date: Thu, 21 Aug 2008 23:12:40 -0700 [thread overview]
Message-ID: <1219385560.14830.103.camel@chandra-ubuntu> (raw)
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.
