System firmware consists of two components, an SP component and a host component. The SP firmware component is located on the SP, and the host component is located on the motherboard. For the server to operate correctly, the firmware in these two components must be compatible.
When replacing the SP, you must restore the configuration settings maintained in the SP. Before replacing the SP, save the configuration using the Oracle ILOM backup utility. Refer to the Oracle ILOM documentation for instructions on backing up and restoring the Oracle ILOM configuration.
After replacig the SP, the new SP firmware component and the existing host firmware component must be consistent with each other. To ensure that the firmware is compatible throughout the server, load new system firmware as described in Install the SP.
