Database Software

I am trying to build Oracle RAC on a shared nothing cluster.
The cluster has multiple nodes and the each node has a disk. (normal shared nothing cluster)

Before I install Oracle Database and RAC, I tried installing Oracle Grid Infrastructure
based on the guide. <http://www.oracle.com/pls/db112/portal.portal_db?selected=11>
As you know, Oracle Database is a shared disk architecture, so I want to create a (virtual) shared disk by ASM,
but I don't really figure out how.

Oracle Grid Infrastructure installer has some node setting, but only looking at the disks on the installer node.
Also, seems that the installer only installs one AMS instance on the installer node.
What I want to do is installing ASM instance on each node and connect them to create a shared disk.
Is there any way to do that by the installer ?
Or Is there any way to do that manually ?
I will be very appreciated if anyone gives me some guides to follow to achieve this.

Thanks in advance.
