Folks, according to DM Multipath - DM Multipath Configuration and Administration
https://docs.google.com/viewer?url=h...path-en-US.pdf, page 17
"Any devices of form /dev/dm-n are for internal use only and should never be used"
The manual suggest using /dev/mapper devices in LVM/Multipath setup on RHEL6
Regards
Peasant.
