[linux-lvm] Using LVM with EMC Powerpath...

["Gary Mansell" <Gary.Mansell@ricardo.com>]

Hi,

I have a powerpath device that I want to encapsulate in LVM so that I
can grow it in the future but when I try and create the physical volume,
I get an error:

[root@ricserver ~]# powermt display dev=emcpowera
Pseudo name=emcpowera

Logical device ID=600601604EC01000E0FC2ED6AAF5DA11 [5FCALRAID5]

When I try to create the physical volume:

[root@ricserver ~]# pvcreate /dev/emcpowera1
  Physical volume "/dev/emcpowera1" successfully created


[root@ricserver ~]# pvscan
