start with installing the GRID software and configure the cluster. Next install the rdbms software. The installer will detect the cluster and give the choice to install the RAC enabled software on both nodes.
If the software is installed, switch the database to use the new installed RAC enabled ORACLE_HOME. When the database is using the RAC software you can add log groups for the new to create thread. When the logs for the new thread are in place, enable the new thread and start the instance on the new node.
This all assumes that all datafiles are on storage that is shared between both nodes. Of course there are some more details but this is roughly the procedure.
