are available for importing and synchronizing.
6.2. Importing
Before distributing packages via RHN Satellite Server, the packages must first be uploaded
to the Satellite. This section describes the process for importing packages and other channel
data.
Important
To populate custom channels correctly, you must first populate at least one Red Hat base
channel. The RHN Satellite Synchronization Tool creates the necessary directory struc-
tures and permissions; without these, the custom channel tools will not work properly. For
this reason, you should use these instructions to set up your base channel(s) and then
refer to the RHN Channel Management Guide for steps to establish custom channels.
6.2.1. Prerequisites
To perform the RHN Satellite Server import, the following prerequisites must be met:
•
The RHN Satellite Server installation must have been performed successfully.
•
The Red Hat Network Channel Content ISOs must be available, or the Satellite must
have access to the Internet and the RHN website.
6.2.2. Preparing for Import
Although it is possible to conduct the import directly from the RHN website, this should
be done only if Channel Content ISOs are not available. It takes a long time to populate a
channel from scratch over the Internet. For this reason, Red Hat urges you to use ISOs, if
they are available, for initial import.
Channel Content ISOs are special collections that contain both packages and XML dumps
of metadata. The ISO images can be downloaded from the RHN website on a machine con-
nected to the Internet and then transferred to the Satellite. After logging in, click Channels
in the top navigation bar and then the name of the channel for your version of RHN Satel-
lite Server. Click the Downloads tab and use the instructions on the page to obtain the
Channel Content ISOs, available by version of Red Hat Enterprise Linux. If the desired
Channel Content ISOs do not appear, ensure your RHN Entitlement Certificate has been
uploaded to RHN and correctly identifies the target channels.
