6.4.4.8.7. System Set Manager

Misc System Preferences —

Toggling the Yes and No radio buttons and then clicking the Change Preferences button alters your

notiﬁcation preferences for the selected systems. All of these preferences may also be applied to

systems individually through the Properties subtab of the System Details page. Refer to Section

6.4.2.6.1.2 System Details

Details Properties for instructions.

• Receive Notiﬁcations of Updates/Errata — This setting keeps you abreast of all advisories per-

taining to your systems. Anytime an update is produced and released for a system under your

supervision, a notiﬁcation is sent via email.

• Include system in Daily Summary — This setting includes the selected systems in a daily sum-

mary 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 re-

boots or failures to check in. In addition to including the systems 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 au-

tomatically applied to systems. 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.

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 three primary types of entitlements:

• Update — should be used to manage a single Red Hat Enterprise 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 man-

agement, and the System Set Manager interface to quickly perform actions on multiple systems.

• Provisioning — offers the highest level of functionality. It should be used to provision multiple sys-

tems that will need to be re-installed and reconﬁgured regularly. The Provisioning offering provides

tools for kickstarting machines, managing their conﬁguration ﬁles, conducting snapshot rollbacks,

and inputting searchable custom system information, as well as all of the functionality included in

the Management service level.

The System Entitlements page allows you to view and promote the entitlements for your registered

systems. Only increases in entitlement levels are allowed. Systems cannot be re-entitled to a lower

entitlement level. For instance, a system entitled to the Update service level can be promoted to the

Management level, but this action cannot be reversed.

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. If no drop-down menu exists for your Update-level system, you may

need to purchase a Management entitlement. Do this through the Buy Now link at the left of the page.
