To apply a specific Errata Update to one or more Management-level 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 4.7 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 5 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If a newer version of the package is already on the system, the package will not be installed on that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.

4.5.2.2. Errata Details
If you click on the Advisory of an Errata Alert in the Relevant or All pages, its Errata Details page
appears. This page is further divided into three tabs:
The Details tab provides the Errata Report issued by Red Hat. It describes the problem and solution
•
and lists the channels it affects. Clicking on a channel name displays the Packages tab of the
Channel Details page. Refer to Section 4.6.1.3 Channel Details for more information.
The Packages tab provides links to each of the updated RPMs broken down by channel. Clicking
•
on the name of a package displays its Package Details page. Refer to Section 4.6.5.3 Package
Details for more information.
The Affected Systems tab shows a list of systems affected by the Errata Alert. You can apply
•
updates here. (See Section 4.5.2.1 Apply Errata Updates.) Clicking on the name of a system takes
you to its System Details page. Refer to Section 4.4.2.6 System Details for more information.
To help users determine whether an update has been scheduled, a Status column exists within the
affected systems table. Possible values are: None, Pending, Picked Up, Completed, and Failed. This
column identifies only the latest action related to an Errata. For instance, if an action fails and you
reschedule it, this column will show the status of the Errata as Pending only (with no mention of
the previous failure). Clicking a status other than None takes you to the Action Details page. This
column corresponds to one on the Errata tab of the System Details page.
