How to install RHCS on RHEL 6.1

Hi ,
I want to install RHCS on a remote RHEL machine. This machine is in amazon ec2, is there any way to do it without accessing the media?

[root@domU-12-31-39-14-15-32 data]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.1 (Santiago)

Thanks in advance.

If you have registered the system, then you can use yum groupinstall to install the cluster groups.

yum grouplist will show you all of the groups.

If you didn't register it or it isn't licensed for cluster services and storage, then it will not be an option. I would suggest SL or CentOS then since they are free.
