oracle auto start asm and mount diskgroups on boot server

Hello,

Instance oracle asm doesn't start on boot.
I have created raw devices  :

vi /etc/udev/rules.d/63-oracle-raw.rules
ACTION=="add", KERNEL=="sdc1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw3 %N"
KERNEL=="raw[1-3]*", OWNER="oracle", GROUP="oinstall", MODE="644
[root@srvtest raw]# chmod 777  /dev/raw/raw1
[root@srvtest raw]# chmod 777  /dev/raw/raw2
[root@srvtest raw]# chmod 777  /dev/raw/raw3

[root@srvtest raw]# chown oracle:dba /dev/raw/raw1
[root@srvtest raw]# chown oracle:dba /dev/raw/raw2
[root@srvtest raw]# chown oracle:dba /dev/raw/raw3

and I have created asmdiskgroup with dbca.

But on boot, asm diskgroup are not mounted

I have to execute chmod and chown on raws and "/etc/init.d/init.cssd stop" then "/etc/init.d/init.cssd start"

Why?

Thanks
