What is the exact error message displayed by OUI ?
Note that you have created ASM disks and not ASM disk groups: ASM disk groups are created by OUI, ASMCA or SQL*Plus but not by oracleasm command.
Please have a look to Troubleshooting the Oracle Grid Infrastructure Installation Process
If you have no error message, just follow ORACLE-BASE recommandation: if the ASM disks are not displayed, click the "Change Discovery Path" button and enter "/dev/oracleasm/disks/*" and click the "OK" button
Thanks for the suggestion.
Found that i have missed one of the asmlib rpm.
Tried installing that RPM and solved.
