If the Oracle ILOM service processor (SP) is hung, Oracle ILOM provides two methods to reset it:
From the Oracle ILOM command-line interface (CLI), type: reset /SP.
From the Oracle ILOM web interface, click Administration > Maintenance > Reset SP.
For more information about resetting the SP from the Oracle ILOM CLI or web interface, refer to the Oracle ILOM Administrator's Guide for Configuration and Maintenance Firmware Release 3.2.x at http://docs.oracle.com/cd/E37444_01/index.html.
