Subject: [PATCH 0/2] Evaluate TPGS setting for ALUA device handler
Date: Thu, 19 Mar 2009 09:05:52 +0100 [thread overview]
Message-ID: <49C1FCE0.3040808@suse.de> (raw)
The ALUA device handler should only be attached if the 'TPGS' setting
in the inquiry structure indicates so. So we should be evaluating the
'tpgs' setting when trying to attach the ALUA device handler.
This way we can get rid of the explicit device table in scsi_dh_alua
and will support any ALUA capable device out-of-the-box.
This is a repost of the patchset send yesterday, including
the suggestions from James B. to just pull the tpgs setting
off the inquiry data instead of adding a new field in the
scsi_device structure.
