CentOS - May 2008 - raw device change back to root after reboot

We are setup new DELL 6800 server fro Informix database.  We create
"raw" partitions and change "raw" partitions owner to
"informix:informix".  After reboot owner change back to
"root".

we don't have problem on CENTOS 3.X, but this problem happen on CENTOS 4.6. 
I double check "SELINUX" is "disable".

does anyone know why it work on 3.X, but NOT on 4.6?

do I need modify /etc/udev/permissions.d/50-udev.permissions?  

if "yes", anyone have sample?

Thanks.

I create a new file /etc/udev/permissions.d/40-informix.permissions
with the following contents:

sdb5:informix:informix:0660
sdb6:informix:informix:0660
sdb7:informix:informix:0660

Of course, your drive devices will vary. Interesting to see someone
else running Informix on CentOS.
