You can update Oracle ILOM system firmware while the host is powered on. The Oracle ILOM firmware image includes firmware for the service processor (SP, Oracle ILOM) and the server's host components (FPGAs). The Oracle ILOM firmware update goes into effect immediately. However, the update of host components is deferred until the affected host is power cycled. Because Oracle ILOM can be updated while the host is powered on, this feature reduces the total system downtime.
