Oracleasm - Instantiating disk : failed

When I configure ASM disks with ASMLib on Oracle Linux 6.2
I got a error


This error is depend  with  SELinux. I  forget set disabled SELinux configuration.

You can disable SELinux on duration of installation Linux



or after installation with change /etc/selinux/config




It is very important for correct operations!

And following video demo showing solve problem when oracleasm createdisk fails.




You can found Oracle Support note : oracleasm createdisk fails with selinux enabled [ID 1430947.1]

Oracle recomended is disable SELinux before installation Oracle RAC!
