6.4.5. System Entitlements
To use all of the features of RHN, your systems must be entitled — subscribed to an RHN
service level. Use the System Entitlements page to configure which systems are entitled
to which service offerings. There are four primary types of entitlements:
•
Update — manages a single Red Hat Enterprise Linux system. It includes Errata Alerts,
Scheduled Errata Updates, Package Installation, and the Red Hat Update Agent .
•
Management — manages multiple systems with multiple system administrators. In ad-
dition 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 mul-
tiple systems.
•
Provisioning — offers the highest level of functionality. It should be used to provision
multiple systems that will need to be re-installed and reconfigured regularly. The Provi-
sioning offering provides tools for kickstarting machines, managing their configuration
files, conducting snapshot rollbacks, and inputting searchable custom system informa-
tion, as well as all of the functionality included in the Management service level.
•
Monitoring — monitors the health of multiple systems. The Monitoring offering pro-
vides probes that watch system metrics and notify Administrators when changes occur.
Such notifications alert Administrators to system performance degradation before it be-
comes critical.
The System Entitlements page allows you to view, add, and remove the entitlements for
your registered systems. Red Hat Network 4.0 allows you to apply and remove entitlements
at will, allowing you to adjust your Red Hat Network infrastructure as your organization
grows and changes.
To change an individual entitlement, select the checkbox to the left of the system, then
click the button that corresponds to the entitlement you wish to add. If clicking on an
entitlement fails to update the information in the table, you may need to purchase additional
entitlements. Check the number of available subscriptions, listed in bold below the table.
Non-RHN Satellite Server customers may purchase more entitlements; click the Buy Now
link at the left of the page to do so.
In addition, you may entitle all newly registered systems to the Management service level
at once by clicking the Auto-Entitle Newest Servers Now link at the bottom of the page.
To use this link, which appears only when new, unentitled systems exist, first make sure
you have enough Management entitlements available. If you need to purchase additional
entitlements, click the Buy more system entitlements now link at the top of the page. Af-
ter auto-entitling, a message appears at the top of the System Entitlements page indicating
the number of systems successfully entitled to the Management service level.
When an entitlement expires, the last system entitled to the same service level (such as
Management) will be unentitled. For instance, if you have 10 Red Hat Enterprise Linux
AS systems entitled to Management and either one of the RHN entitlements or one of the
operating system subscriptions expire, the last system subscribed or entitled will have their
subscription or entitlement removed.
