Hello Friendz

Oracle 10.0.3.0
RHEL 4.0

I have configured raw devices and then use then in ASM diskgroup.
The owner of these raw device was root. Group was Disk
I have changed the owner to Oracle user.
But whenever i reboot the system, the owner aging changed to Root and the group to Disk. Because of this, Asm is not able to mount the diskgroup (because , no rights on those raw disks)

So friends, i don't know how should i solve this matter..
Is that any file where i have to make entry?

Please guide me if you know...

Thanks..

Dipali

Try it.

Edit the /etc/sysconfig/rawdevices file, adding the following lines.

    /dev/raw/raw1 /dev/sdb1
    /dev/raw/raw2 /dev/sdc1
    /dev/raw/raw3 /dev/sdd1

Restart the rawdevices service using the following command.

    service rawdevices restart

Run the following commands and add them the /etc/rc.local file.

    chown oracle:oinstall /dev/raw/raw1
    chown oracle:oinstall /dev/raw/raw2
    chown oracle:oinstall /dev/raw/raw3
    chmod 600 /dev/raw/raw1
    chmod 600 /dev/raw/raw2
    chmod 600 /dev/raw/raw3

The ASM raw device disks are now configured.

Hi,

Thanks Dreamz..
I had done these steps.. Actually i was asking for the other thing. Any ways..
Now i have done asm successfully.

I change the file /var/lock/subsys/local to add the permission related commands, which will be run after all other init scrips..
Now every thing is fine..
