6.4.4.6. System Set Manager Channels —
Options to manage channel associations through the following subtabs:
6.4.4.6.1. System Set Manager Channels Channel Subscriptions —
To subscribe or unsubscribe the selected systems in any of the channels, toggle the appropriate radio
buttons and click the Alter Subscriptions button.
6.4.4.6.2. System Set Manager Channels Config Channels —
Like the options within the
System Details Channels Configuration
tab, the subtabs here
can be used to subscribe the selected systems to configuration channels and deploy and verify the
configuration files on the systems. The channels are created in the Manage Config Channels interface
within the
Channels
category. Refer to Section 6.6.6 Manage Config Channels — for channel
creation instructions.
To manage the configuration of a system, it must have the latest
rhncfg*
packages installed and
the
configfiles/
directory and associated files created on it. Refer to Section 6.6.6.1 Preparing
Systems for Config Management for instructions. Command line options also exist for many of these
functions. Refer to Appendix A Command Line Config Management Tools for instructions.
6.4.4.6.2.1. System Set Manager Channels Config Channels Subscriptions —
On this subtab, enter numbers in the Rank column to establish the order in which channels are used,
lowest first. Channels with no numeric value are not associated with the systems. Your local configu-
ration channel will always override all other channels. Once you’ve established the rank of the config
channels, you must decide how they should be applied to the selected systems.
The three buttons below the channels reflect your options. Clicking
Add with Highest Rank
places
all the ranked channels before any channels already subscribed to by the systems. Clicking Add with
Lowest Rank
places the ranked channels after channels subscribed to by the systems. Clicking
Re-
place Existing Config Channels removes any existing association and starts cleanly with the ranked
channels, leaving every system with the same config channels in the same order.
In the first two cases, if any of the newly ranked config channels is already in a system’s existing con-
fig channel list, the duplicate channel is removed and re-added according to the new rank, effectively
reordering the system’s existing channels. When such conflicts exist, you’re presented with a confir-
mation page to ensure the intended action is correct. When the change has taken place, a message
appears at the top of the page indicating the update was successful.
6.4.4.6.2.2. System Set Manager Channels Config Channels Deploy —
Use this subtab to distribute configuration files from your central repository on RHN to the selected
systems at once. The table lists the configuration files associated with any of the selected systems.
Clicking the name of a file opens its
Configuration File Details
page. Clicking its system count
displays the systems already subscribed to the file.
To subscribe the selected systems to the available configuration files, select the checkbox for each
desired file. When done, click Deploy Configuration and schedule the action. Note that the files
deployed are of the latest version at the time of scheduling and do not account for versions that may
appear before the action takes place.
