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 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.

2.1. satellite-sync

The RHN Satellite Synchronization Tool enables an RHN Satellite Server to update its

database metadata and RPM packages with those of RHN's central servers, another Satellite

within your organization, or local media. To launch it, execute the following command as root:

satellite-sync

This tool can be used in a closed environment, such as the one created with a disconnected

install, or it may obtain data directly over the Internet. Closed environment imports can get their

data from downloaded ISOs or from the XML data generated by RHN Satellite Exporter.

The RHN Satellite Synchronization Tool works incrementally, or in steps. For it to obtain

Errata information, it must first know the packages contained. For the packages to be updated,

the tool must first identify the associated channel(s). For this reason, the RHN Satellite

Synchronization Tool performs its actions in the following order:

1. channel-families — Import/synchronize channel family (architecture) data.

2. channels — Import/synchronize channel data.

3. rpms — Import/synchronize RPMs.

4. packages — Import/synchronize full package data for those RPMs retrieved successfully.

5. errata — Import/synchronize Errata information.

Each of these steps can be initiated individually for testing purposes with the effect of forcing

the tool to stop when that step is complete. All steps that precede it, however, will have taken

place. Therefore, calling the rpms step will automatically ensure the channels and

channel-families steps take place first. To initiate an individual step, use the --step option,

like so:

satellite-sync --step=rpms
