OS : Oracle Linux 6.8 (64 Bit)
For Oracle Linux, I don't need to install oracleasm as it is already part of the kernel.
But I still need to install oracleasmlib and oracleasm-support packages
oracleasmlib can be installed using the rpm provided in the following link.
http://www.oracle.com/technetwork/server-storage/linux/asmlib/ol6-1709075.html

But, is it better to install both of them using yum rather individually installing packages?
If installing individually as packages , I need to install oracleasmlib package before I install oracleasm-support . Right ?
I will be installing Grid infrstructure 11.2.0.4 (3-Node RAC) after I install and configure ASMLib.
