Description Bryn M. Reeves 2008-02-26 13:40:39 EST
Description of problem:
RHEL5 now supports the kernel hardware handler for the HP MSA/HSV active/passive
storage controllers. Upstream multipath-tools now has a path prioritiser for
these arrays as well.

This was merged in this commit:


    "All paths from a controller with HP Active/Standby firmware
    should really be grouped according to their status; otherwise
    the path switching will not work properly or you can use only
    one path to that array.
    This patch adds a new priority checker 'mpath_hp_sw' which
    will allow these paths to be grouped accordingly."

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. # rpm -ql device-mapper-multipath | grep mpath_prio_hp_sw
Actual results:
No path prioritiser for these SANs.

Expected results:
