6.4.2. Systems

The Systems page displays a list of all of your registered systems. The Systems list contains several columns of information for each system:
  • Select — Update or unentitled systems cannot be selected. To select systems, mark the appropriate checkboxes. Selected systems are added to the System Set Manager. After adding systems to the System Set Manager, you can use it to perform actions on them simultaneously. Refer to Section 6.4.4, “System Set Manager — for details.
  • 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 sub-tab of the packages list, while the Critical Updates icon links directly to the Update Confirmation page. Also, the Not Checking In icon is linked to instructions for resolving the issue.
    • — System is up-to-date
    • — Critical Errata available, update strongly recommended
    • — Updates available and recommended
    • — System is locked; Actions prohibited
    • — System is being kickstarted
    • — 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, imagine a client system that has an early version of a package installed. If this client is then subscribed to the appropriate base channel of RHN (such as Red Hat Enterprise Linux 4), that channel may have an updated version of the package. If so, the package appears in the list of available package updates.


    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, “System Details” or Section, “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, “System Details” for more information.
  • Base Channel — The primary channel for the system, based upon its operating system distribution. Refer to Section 6.6.1, “Software 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. All

The All page contains the default set of your systems. It displays every system you have permission to manage. A user has permission to manage a system if he is the only user in his organization, if he is an Organization Administrator, or if the system is a member of a group to which he has admin rights.
