Apply all applicable Errata Updates to a system by clicking on Systems => Systems in
the top and left navigation bars. Click on the name of an entitled system, and click the
Errata tab of the resulting System Details page. When the Relevant Errata list appears,
click Select All then the Apply Errata button on the bottom right-hand corner of the page.
Only those Errata that have not been scheduled or were scheduled and failed or canceled
are listed. Updates already pending are excluded from the list.
In addition, Management users can apply Errata Updates using two other methods:
To apply a specific Errata Update to one or more systems, find the update within the
•
Errata lists. In the table, click on the number of systems affected, which takes you to the
Affected Systems tab of the Errata Details page. Select the individual systems to be
updated and click the Apply Errata button. Double-check the systems to be updated on
the confirmation page, then click the Confirm button.
To apply more than one Errata Update to one or more systems, select the systems from
•
a Systems list and click the Update List button. Click the System Set Manager link
in the left navigation bar, then click the Systems tab. After ensuring the appropriate
systems are selected, click the Errata tab, select the Errata Updates to apply, and click
the Apply Errata button. You can select to apply the Errata as soon as possible (the next
time the Red Hat Network Daemon on the client systems connect to RHN) or schedule a
date and time for the Errata Updates to occur. Then click the Schedule Updates button.
You can follow the progress of the Errata Updates through the Pending Actions list.
Refer to Section 6.7 Schedule for more details.
Important
If you use scheduled package installation, the packages are installed via the
RHN Daemon. You must enable the RHN Daemon on your systems. Refer to
Chapter 3 Red Hat Network Daemon for more details.
The following rules apply to Errata Updates:
Each package is a member of one or more channels. If a selected system is not subscribed
•
to a channel containing the package, the package will not be installed on that system.
If a newer version of the package is already on the system, the package will not be
•
installed on that system.
If an older version of the package is installed, the package will be upgraded.
