6.5.2. All Errata
The All Errata page displays a list of all Errata Alerts released by Red Hat. It works much the same
as the Relevant Errata page in that clicking either the Advisory or the number of systems affected
takes you to related tabs of the Errata Details page. Refer to Section 6.5.2.2 Errata Details for more
information.
6.5.2.1. Apply Errata Updates
Errata Alerts include a list of updated packages that are required to apply the Errata Update. To apply
Errata Updates to a system, the system must be entitled.
You can 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 and Provisioning 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 or by
searching. In the table, click on the number of systems affected, which will take you to the Affected
Systems tab of the Errata Details page. Then, individually select the 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 Er-
rata 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 sys-
tems 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 will be installed via the RHN Daemon. You
must have the RHN Daemon enabled 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.
