A System Software Release is associated with Oracle ILOM firmware version, and with the latest operating system support updates and patches. Newer Oracle ILOM firmware versions have a higher number or a letter added. For example, a current Oracle ILOM firmware version number might be 4.0.2.24, and a future Oracle ILOM firmware version number might be 4.0.2.24a.
Some product features are enabled only when the latest versions of operating system, patches, and firmware are installed. To retain optimal system performance, security, and stability, you must install the latest available operating system, patches, and firmware.
To verify that the server is running the minimum supported Oracle ILOM firmware version or newer. Refer to the server Product Notes for the minimum supported firmware version.
