Configuration of Linux cluster managment on Red Hat 5.x server

Hi Experts,

I have question regarding linux cluster managment on Red Hat 5.x server. When I try to install 'luci' or 'ricci' in one of our linux servers it is giving me below error:-

yum install luci
Loaded plugins: katello, product-id, rhnplugin, security, subscription-manager
Updating certificate-based repositories.
Unable to read consumer identity
Setting up Install Process
No package luci available.
Nothing to do

Do we have to purchase seperate license for linux cluster managment? Is there any trial version where in we can test this coniguration?:rolleyes:

Appreciate your help!!

Thanks
