6.5.2.1. Apply Errata Updates
Errata Updates 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.
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 6.8, “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• If a newer version of the package is already on the system, the package will not be installed on that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.
6.5.2.2. Errata Details
If you click on the Advisory of an Errata Update in the
Relevant
or
All
pages, its
Errata Details
page
appears. This page is further divided into the following tabs:
