Description Gris Ge 2010-11-04 01:57:33 UTC 
Description of problem:

multipath device does not show as /dev/mapper/mpathN in sfdisk -d
Even /dev/dm-N and /dev/mapper/mapthN are indentical in major:miner way.
But as document say, we suggest user to use /dev/mapper/mpathN instead of /dev/dm-N


Version-Release number of selected component (if applicable):
RHEL 5.5 with device-mapper-multipath upgrade to 0.4.7-39.el5
util-linux-2.13-0.52.el5_4.1
device-mapper-multipath-0.4.7-39.el5


Steps to Reproduce:
1. Setup a multipath enviroment.
2. sfdisk -d
  
Actual results:
sfdisk use /dev/dm-N to indicate the multipath device

Expected results:
sfdisk use /dev/mapper/mpathN to indicate the multipath device.

Closing, problem fixed on RHEL6, bugfix is not possible to backport to RHEL5 (because depends on kernel and new sysfs stuff). Thanks.
