In Oracle ILOM you can enable or disable the requested state for Automatic System Recovery (ASR) components, such as, processors and memory modules.
Disabling ASR components in Oracle ILOM is done when you want to remove resources from the available resource list. For example, you might disable an ASR component when you replace a component or remove it from the server. After you disable an ASR component in Oracle ILOM, the component becomes non-operational and is no longer eligible for booting. Enabling a disabled ASR component in Oracle ILOM is done when you are ready to make the ASR component operational and eligible for booting.
