Description Guil Barros 2012-02-22 20:16:29 UTC 
Description of problem:
LVM will currently pick a path for a pv instead of the powerpath device. The functionality requested is for lvm to notice the emcpower device and hook up to that instead. This is already committed upstream here:

http://sourceware.org/cgi-bin/cvsweb.cgi/LVM2/lib/filters/filter.c.diff?r1=1.66&r2=1.67&cvsroot=lvm2

Version-Release number of selected component (if applicable):
lvm2-2.02.87-6.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. Configure a system with EMC PowerPath as the mp driver
2. use lvm
  
Actual results:
# pvscan -v
    Wiping cache of LVM-capable devices
    Wiping internal VG cache
    Walking through all physical volumes
  PV /dev/cciss/c0d2p1    VG rootvg          lvm2 [33.91 GiB / 0    free]
  PV /dev/sda   VG vg1         lvm2 [34.69 GiB / 0    free]
...

Expected results:
# pvscan -v
    Wiping cache of LVM-capable devices
    Wiping internal VG cache
    Walking through all physical volumes
  PV /dev/cciss/c0d2p1    VG rootvg          lvm2 [33.91 GiB / 0    free]
  PV /dev/emcpoweraa   VG vg1         lvm2 [34.69 GiB / 0    free]
