If you click the Systems tab on the top navigation bar, the Systems category and links appear. The pages in the Systems category allow you to select systems so that you can perform actions on them and create System Profiles.
As shown in Figure 4-3, the Systems page displays a list of all your registered systems. The Systems list contains several columns of information for each system:
Status — Shows which type of Errata Alerts are applicable to the system or confirms that it is up-to-date. Some icons are linked to pages providing resolution. For instance, the standard Updates icon is linked to the Upgrade subtab of the packages list, while the Critical Updates icon goes directly to the Update Confirmation page. Also, the Not Checking In icon is linked to instructions for resolving the issue, while the Unentitled icon goes to the Buy Now page, if the user is an Organization Administrator.
— System is up-to-date
— Critical Errata available, update
strongly recommended
— Updates available and recommended
— Updates have been scheduled
— System not checking in properly (for 24 hours or more)
— System not entitled to any update service
Errata — Total number of Errata Alerts applicable to the system.
Packages — Total number of package updates for the system. Includes packages from Errata Alerts as well as newer packages that are not from Errata Alerts. For example, if a system is subscribed to the Red Hat Linux 7.1 i386 channel that contains version 2.5.4 of a package because that is the version that shipped with Red Hat Linux 7.1, but the system has version 2.5.2 of the package installed, the newer version of the package will be in the list of updated packages for the system.
 | Important |
|---|---|
If the RHN website identifies package updates for the system, yet the Red Hat Update Agent responds with "Your system is fully updated" when run, a conflict likely exists in the system's package profile or in the up2date configuration file. To resolve the conflict, either schedule a package list update or remove the packages from the Package Exceptions list for the Red Hat Update Agent. Refer to Section 4.4.1.5 System Details or Section 2.4.1.3 Package Exceptions Settings, respectively, for instructions. |
System — The name of the system as configured when registering it. The default name is the hostname of the system. Clicking on the name of a system takes you to the System Details page for the system. Refer to Section 4.4.1.5 System Details for more information.
Base Channel — The primary channel for the system, based upon its operating system distribution. Refer to Section 4.6.1 Channels for more information.
Entitlement — Whether or not the system is entitled and at what service level.
Links in the left navigation bar below Systems enable you to select and view predefined sets of your systems. All of the options described above can be applied within these pages.
The All page contains the default set of your systems. It displays every system you've registered with Red Hat Network.
The Out of Date page displays the registered systems that have applicable Errata Alerts that have not been applied.
The Unentitled page displays the registered systems that have not yet been entitled for Red Hat Network service.
The Inactive page displays the registered systems that have not checked into RHN for 24 hours or more. When the Red Hat Update Agent connects to RHN to see if there are any updates available or if any actions have been scheduled, this is considered a checkin. If you are seeing a message indicating checkins are not taking place, the RHN client on your system is not successfully reaching Red Hat Network for some reason. This indicates:
The system is not entitled to any RHN service. System Profiles that remain unentitled for 180 days (6 months) are removed.
The system is entitled, but the Red Hat Network Daemon has been disabled on the system. Refer to Chapter 5 Red Hat Network Daemon for instructions on restarting and troubleshooting.
The system is behind a firewall that does not allow connections over https (port 443).
The system is behind a proxy that has not been properly configured.
Some other barrier exists between the system and the RHN Servers.
If you click on the name of a system on any page, it will display the System Details page for the system. From here, you may modify this information or remove the system altogether by clicking the delete system link on the top-right corner.
The System Details page is further divided into tabs:
Details — Displays information about the system. This is the first tab you see when you click on a system. 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. Be sure you review the Errata List for the system before performing this action. After clicking the button, you will be asked to confirm the update. Click the Confirm Update button to complete the update. After confirming, the action is added to the Pending Actions list under Schedule => Pending Actions from the top and left navigation bars, respectively.
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. 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 notification is sent via email.
Include system in daily summary report calculations — This setting includes the Management 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 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. 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. 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 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 Affected Systems tab of the Errata Details page.
Packages — Manages the packages on the system.
Packages — The default display of the Packages tab describes the options available to you and provides the means to update your package list. If after exploring the packages, you believe the list is outdated or incomplete (or you installed the packages manually and did not have RHN install them), click the Update Package List button on the bottom right-hand corner of this page. The next time the RHN Daemon connects to RHN, it will update your System Profile with the latest list of installed packages.
List/Remove — Lists installed packages from the system's software System Profile and enables you to remove them. Click on a package name to view its Package Details page. (Refer to Section 4.6.5.3 Package Details.) To delete packages from the system, select their checkboxes and click the Remove Packages button on the bottom right-hand corner of the page. A confirmation page will appear with the packages listed. Click the Confirm button to remove the packages.
 | Note |
|---|---|
If you are using up2date version 3.1 or higher, any dependency-related errors generated by the attempted package removal are displayed on the page. |
Upgrade — Displays a list of packages that have a new version available based on the package versions in the channel for the system. Click on the latest package name to view its Package Details page. To upgrade packages immediately, select them and click the Upgrade Packages button. To download the packages as .tar files, select them and click the Download Packages button. Refer to Section 4.6.5.2 Package Download for details.
Install — Enables you to install new packages on the system from the available channels. Click on the package name to view its Package Details page. To install packages, select them and click the Install Selected Packages button.
Channels — Provides a predetermined method for systems to obtain regular updates, based upon their operating systems, packages and, functionality. Click a channel name to view its Channel Details page. To modify the child channels associated with this system, use the checkboxes next to the channels and click the Change Subscriptions button. You will receive a success message or be notified of any errors. Refer to Section 4.6.1 Channels for more information.
Notes — Provides you with 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.
Events — Displays past, current, and scheduled actions on the system. You may cancel pending events here.
History — The default display of the Events tab lists the type and status of events that have failed, occurred or are occurring. This list is automatically generated. To view details of an event, click its summary in the System History table. To again view the table, click Return to history list at the bottom of the page.
Pending — Lists events that are scheduled but have not begun. To unschedule a pending event, select the event and click the Cancel Events button at the bottom of the page.
To use all of the features of RHN, your systems must be entitled — subscribed to an RHN service level. Every user receives one free Red Hat Network Update entitlement subscription.
Use the System Entitlements page to configure which systems are entitled to which service offerings. There are two types of entitlements:
Update — should be used to manage a single Red Hat Linux system. It includes Errata Alerts, Scheduled Errata Updates, Package Installation, and the Red Hat Update Agent.
Management — should be used to manage multiple systems with multiple system administrators. In addition to the features of the Update offering, it includes system group management, user management, and the System Set Manager interface to quickly perform actions on multiple systems.
The System Entitlements page allows you to view and change the entitlements for your registered systems. To change an individual entitlement, select the entitlement from the system's pulldown menu and click the Update Entitlements button on the bottom right-hand corner of the page. Click the name of a system to see details about it.
