We're trying to install the latest version of NagiosXI on a fresh system. This is the error I encounter after running the install script.

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
ERROR: Please add the 'Optional' channel to your Red Hat systems subscriptions.
You can do so in the Redhat Network web interface or using the rhn-channel command.
or, install the yum-utils package and use the following command:
yum-config-manager --enable rhel-6-server-optional-rpms
-------------------------------------------------------------------------------------------------------------------------------

This machine was registered through Red Hat Subscription Manager. But I was unable to add "Optional" channel via web or CLI.
Also tried the YUM command but failed.

[root@bcsnsnagios1 nagiosxi]# yum-config-manager --enable rhel-6-server-optional-rpms

This system is receiving updates from RHN Classic or RHN Satellite.
