System firmware consists of two components, an SP component and a host component. The SP firmware component is located on the SPM, 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 SPM, you must restore the configuration settings maintained in the SPM. Before replacing the SPM, 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 replacing the SPM, the new SPM 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 SPM.
