Subject: [PATCH 0/2] Fix a couple hpsa bugs related to device discovery
Date: Thu, 16 Dec 2010 13:00:51 -0600 [thread overview]
Message-ID: <20101216185823.545.99641.stgit@beardog.cce.hp.com> (raw)
This series fixes a couple of bugs related to discovering changes to
devices. 1) We should not consider a firmware change to mean the
device identity has changed. Just because a logical drive's firmware
changes doesn't mean it's not the same drive with the same data, so
it should not be removed and re-added to the scsi mid layer.
2) Likewise if the RAID level is observed to change. This can happen
for instance by doing a RAID level migration from with the Array
Configuration Utility.
