Patch for Linux 7.0 will only allow you to download meta data and packages for those Red Hat errara associated with channels for which the notification server has information indicating there are one or more computers in your environment with a valid subscription to those channels.
If there are no computers in your environment that are registered with the Red Hat Network with respect to a particular channel, then you will not be able to download packages related to errata associated with such channel.
This design was changed in Patch for Linux 7.1. The channels that you are able to download is now determined by the Red Hat Network or Novell mirror credentials that you enter in the Altiris console, rather than entitlement information collected from each of the computers in your environment.
