Chapter 9 About Applying Errata to Systems and System Groups
Spacewalk enables you to monitor available errata and gives you precise control when applying errata to systems. You can see the errata that are available for a selected system or system group on the Errata page of the web interface. Applying filters enables you to display errata according to whether they are noncritical, bug fix advisory, product enhancement advisory, or security advisory.
You can also use the spacecmd command with the following subcommands to monitor and manage errata:
-
system_listerrata – Provides similar functionality. For example, list the errata that are available for a specified system.
-
erratadetails – Displays additional information about a given erratum.
-
system_applyerrata – Applies errata to multiple systems within a system group at the same time.
If you configured the OSA daemon (osad) on a
client, the erratum is applied immediately. If a client system is
not configured with Ksplice, you must reboot the system for kernel
changes to take effect. A client system that uses Ksplice can take
advantage of the kernel changes that result from a channel change
without the need to reboot.
