In addition, some functions can be accessed only on this tab. Most importantly, a Management-
entitled 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 Manage-
ment system in a daily summary of system events. (By default, all Management systems are
included in the summary.) These are actions affecting packages, such as scheduled Errata Up-
dates, 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.
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.
•
Errata
— Contains a list of Errata Alerts applicable to the system. To apply updates, select them
and click the
Apply Errata
button. Double-check the updates to be applied on the confirmation
page, then click the
Confirm
button. After confirming, the action is added to the
Pending Actions
list under
Schedule
. Errata that have been scheduled cannot be selected for update. In the place of
a checkbox, you will find a clock icon that, when clicked, takes you to the
Action Details
page.
To help users determine whether an update has been scheduled, a Status column exists within the
Errata 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 resched-
ule it, this column will show the status of the Errata as Pending only (with no mention of the
