Redhat Enterprise Linux 6.2 Evaluation Copy - Clustering Software packages

I am new in Redhat.

I have downloaded & installed & registered Redhat Ent Linux 6.2 eval copy.

I am trying to install redhat clustering software packages like cman,luci etc via the yum install command, but seems like it is not available (see messages below).

[root@localhost benny]# yum install cman
Loaded plugins: product-id, refresh-packagekit, rhnplugin, security,
              : subscription-manager

Setting up Install Process
No package cman available.
Error: Nothing to do

Where could I download or get the eval copy of redhat clustering software packages??

Thanks & regards,

Benny
