Red Hat NETWORK 3.4 - PROVISIONING Reference Manual page 61

Chapter 4. Red Hat Network Website
states "Critical updates available" you may click the update now link to apply all relevant Errata
Updates to the individual system, as you would under the Errata tab.
In addition, some functions can be accessed only on this tab. Most importantly, a system may be
locked by clicking the Lock system link near the bottom-left corner of the page. This prohibits the
scheduling of any action through RHN that would affect the system, including package updates and
system reboots. To undo this, click the Unlock system link in the same location.
The packages will be updated by 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 Details tab
contains the following subsets of information:
Overview — A summary of the system's details. In addition to the system status message,
•
the Overview subtab contains basic System Info, Subscribed Channels, and System Properties.
Clicking the Alter Channel Subscriptions link takes you to the Channels tab, while clicking
the Edit these properties link takes you to the Properties subtab. See the following sections for
more information.
Properties — The profile name, entitlement level, notification choice, daily summary, auto-
•
Errata update, and physical location of the system, including street address, city, state, country,
building, room, and rack. To modify this information, make your changes and click the Update
Properties button. Note that many of these properties can be set for multiple systems at once
through the System Set Manager interface. Refer to Section 4.4.4 System Set Manager for de-
tails. The following properties deserve additional explanation:
Receive Notifications of Updates/Errata — This setting keeps you abreast of all advisories
•
pertaining to the system. Anytime an update is produced and released for the system, a notifi-
cation is sent via email.
Include system in daily summary report calculations — This setting includes the system
•
in a daily summary of system events. (By default, all Management and Provisioning systems
are included in the summary.) These are actions affecting packages, such as scheduled Errata
Updates, and system reboots or failures to check in. In addition to including the system here,
you must choose to receive email notifications in the Your Preferences page of the Your RHN
category. Refer to Section 4.3.2 Your Preferences for instructions. Note that RHN will send
these summaries only to verified email addresses.
Automatic application of relevant errata — This setting allows you have all Errata Updates
•
automatically applied to a system. This means packages associated with Errata will be updated
without any user intervention. Customers should note that Red Hat does not recommend the
use of the auto-update feature for production systems because conflicts between packages and
environments can cause system failures. The Red Hat Network Daemon must be enabled on
the systems for this feature to work.
Hardware — Detailed information about the system, including networking, BIOS, storage, and
•
other devices. This appears only if you selected to include the hardware profile for this machine
during registration. If the hardware profile looks incomplete or outdated, click the Schedule
Hardware Refresh button to schedule a Hardware Profile update for your system. The next time
the RHN Daemon connects to RHN, it will update your System Profile with the latest list of
hardware.
Notes — A place to create notes about the system. To add a new note, click the create new note
•
button, type a subject and details, and click the Create button. To modify a note, click on its
subject in the list of notes, make your changes, and click the Update button. To remove a note,
click on its subject in the list of notes and then click the delete note button.
Custom Info — Completely customizable information about the system. Unlike a note, infor-
•
mation included here is more formal and can be searched upon. For instance, you may decide to
identify the cubicle in which each system is located. To do this, you must first create a cubicle
key within the Custom System Info page. Refer to Section 4.4.9 Custom System Info for instruc-
