from Metalink


Add the required raw device ownership and permissions, for example:
# vi /etc/udev/rules.d/99-raw.rules
KERNEL=="raw[1-2]*", OWNER="root", GROUP="oinstall", MODE="640"
KERNEL=="raw[3-5]*", OWNER="oracle", GROUP="oinstall", MODE="660"


or

[root@rac1 ~]# cat /etc/udev/rules.d/99-raw.rules
KERNEL=="raw[1-2]*", OWNER="root", GROUP="oinstall", MODE="640"
KERNEL=="raw[3-5]*", OWNER="oracle", GROUP="oinstall", MODE="660"


Restart the UDEV service
Restart the UDEV service as follows, after which devices should now reflect their intended ownership and permissions:

On SLES10:
# /etc/init.d/boot.udev stop
# /etc/init.d/boot.udev start

On RHEL5/OEL5:
# udevcontrol reload_rules
# start_udev
