Looking for a good HA Clustering tutorial

I am trying to setup R.H. HA on a pair of web servers. My goal is to have a single LUN presented to the two servers, one primary and the other the failover. 

 

I've been reading over the RHEL 6.0 Cluster Administration doc.  The issue is, I've never setup a cluster before, and I'm am having some difficulties.

 

The doc is written good, but it seems to take into assumption that a person has done clustering before, which I have not.  I think that I need a good tutorial, hopefully a video, that will walk me through setting up a high availability clustered environment.  Can someone point me to a good resource?

 

Thanks.

 

Daryl
