Bug#661057: linux-2.6: hpsa driver does not support multipath on Smart Array 712m with latest firmware
Package: linux-2.6
Severity: important
Tags: patch
The hpsa driver fails to correctly assign devices when there are
multiple paths on at least the Smart Array 712m with the latest
firmware.
The end result is only one device node is created in /dev and multipath
tools then only detect one path.
Applying the patch here:
http://www.spinics.net/lists/linux-scsi/msg56690.html
to the current stable version of the squeeze kernel fixes the issue.
This was tested on a Smart Array 712m, connected via 2 SAS switches to a
HP P2000 G3 SAS Array.
