Action: Before proceeding with the installation, you must deconfigure CSS, shut down any Automatic Storage Management (ASM) instances, and shut down all databases that use ASM for storage on all of the nodes previously listed. This installation brings up a clusterwide version of CSS after installation is complete. At that point, you may start up any databases and ASM instances that previously used CSS. When they are brought back up, they will use the clusterwide CSS version.
