Have you tried to use the package oracleasm?
This package installs some binaries to manipulate ASM Disks, creating new devices (based on the originals /dev/sd*), into /dev/oracleasm/ and changing the owner of the devices.
Oracle Database does not use raw devices in RHEL anymore, by default. They recommend installing this package and administrate everything by it.

I hope this helps.

Hi,
I just can't find any pointers. Problem is, our database guys want to
use Oracle ASM (which is some kind of raw devices). To not mix things up
between regular volumes and ASM devices, we decided to put them into a
special vg (yes, oracle recommends against it, but you somehow has to
administer the machines. And looking into their shell scripts, it seems
to not being a thing of reason but more the lack of know how of handling
arbitrary block devices).
Anyway, we'd like the devices to end up with owner oracle:dba. There
seems to be no way, as udev does not create the devices but vgchange, to
change the ownership than by using a start script somewhere between
vgchange time and oracle asm start up.
Is there any other, more "canonical" way?
