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 structures and permis-
sions; 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 CDs 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 CDs (or 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 CDs, if they are available, for
initial import.
Channel Content CDs are special collections that contain both packages and XML dumps of metadata.
If the Channel Content CDs don't accompany the Satellite Installation CD, the ISO images can be
downloaded from the RHN website. After logging in, click Channels in the top navigation bar and
then the name of the channel for your version of RHN Satellite Server. Click the Downloads tab and
use the instructions on the page to obtain the Channel Content ISOs, designated as "channel" ISOs.
If the desired Channel Content ISOs don't appear, ensure your RHN Entitlement Certificate has been
uploaded to RHN and correctly identifies the target channels.
Channel content, whether it comes in the form of physical discs or downloadable ISOs, is mounted and
then copied to a temporary repository directory. Before mounting the CDs/ISOs, ensure the temporary
repository has enough disk space to copy all the contents into a single directory. For a single channel,
the approximate required space is 3 GB. The process to copy channel CDs/ISOs is to mount each one,
copy its contents to the temporary repository, and then unmount the CD/ISO. Repeat. Each channel
consists of several CDs/ISOs. Once finished, the administrator should delete the temporary directory
and all of its contents. Follow these steps:
1. Log into the machine as root.
2. Insert the first Channel Content CD or ISO that has been burned to disc.
3. Create a directory in
mkdir /mnt/import
4. If you are installing from official CD and it is not mounted automatically, mount it using the
command:
mount /dev/cdrom /mnt/import
If you are installing from ISO, mount the file from within the directory containing it using the
command:
mount iso_filename /mnt/import -o loop
5. Create a target directory for the files, such as:
mkdir /var/rhn-sat-import/
to store the file(s) with the command:
/mnt
