** Please download Oracle ASM Lib from OTN.
oracleasmlib-2.0.2-1.i386.rpm (or) you can configure this when you setup Linux by selecting
System Tools -> oracle oracleasm-2.6.9.. (driver for UP kernel).
[root@oracledb2 init.d]# ls -ltr oracleasm*
-rwxr-xr-x 1 root root 18114 Oct 24 2006 oracleasm
[root@oracledb2 init.d]# pwd
/etc/init.d
Usage: /etc/init.d/oracleasm {startstoprestartenabledisableconfigurecreatediskdeletediskquerydisklistdisksscandisksstatus}

For rest of the steps please follow the above URL to add the disks using oracleasm.
[root@oracledb2 init.d]# /etc/init.d/oracleasm listdisks
VOL1
VOL2
VOL3
Once you have the disks in place, login as Oracle user and run DBCA
1. Select Configure Automatic Storage Management : Step 1 of 4 -> Click Next

2. A warning screen will appear. For ASM (Automatic Storage Management) the Oracle Cluster Synchronization Service (CSS) needs to be running. All you need to do is - login as a root user and run the localconfig reset from $ORACLE_HOME/bin directory, as shown in the below screen.

3. Open a termial / Putty section login as a root user, and execute localconfig reset from $ORACLE_HOME/bin.

Once you have the message "Oracle CSS service is installed and running under init" you can click "OK" at the warning screen.
4. Specify the password for the SYS user. (This is for ASM Instance).

7. I have missed few of the screens, you need to assign the Disk Group Name, assign the Volumes that we create before and select the redundancy. I created two Disk Group's.

+DATA/DB11G

CONTROLFILE/

DATAFILE/

ONLINELOG/

PARAMETERFILE/

TEMPFILE/

spfiledb11g.ora => +DATA/DB11G/PARAMETERFILE/spfile.280.674840503

And the second group RECOVERYDEST/ for FLASH recovery area.

8. Mount the Disks - Click Mount All

9. Mounting Disk Groups...10. Disks are mounted, Next we create database.
