6.4.2.6.1. System Details Details
Displays information about the system. This is the first tab you see when you click on a system.
It offers direct access to some of the functionality provided in subsequent tabs. For instance, under
the System Info heading, a message should appear describing the status of this machine. If it 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 Management-level 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 Details tab contains the following subsets of information:
6.4.2.6.1.1. System Details
Details 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.
6.4.2.6.1.2. System Details
Details Properties
The profile name, entitlement level, notification choice, daily summary, auto-Errata update, and phys-
ical 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 inter-
face. Refer to Section 6.4.4 System Set Manager — for details. The following properties deserve
additional explanation:
• Receive Notifications of Updates/Errata — This setting keeps you abreast of all advisories per-
taining to the system. Anytime an update is produced and released for the system, a notification 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 6.3.2 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 auto-
matically 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.
6.4.2.6.1.3. System Details Details 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
