the information in this chapter regarding the configuring of serial ports, and modems attached to those serial ports, applies only to the serial ports (s1 and s2) on the service processor/pci backplane (location u0.1-p2). none of this information is applicable to the serial ports, or modems attached to those serial ports, on the hardware management console for pseries (hmc).

    on some of the system management services (or service processor) screens, you will see the term lpar. lpar is equivalent to the term partitioned system.

    the service processor runs on its own power boundary and continually monitors hardware attributes and the environmental conditions within the system. the service processor is controlled by firmware and does not require the aix operating system to be operational to perform its tasks.

    the service processor menus allow you to configure service processor options, as well as enable and disable functions.

    service processor menus are available using an hmc virtual terminal window when ok is displayed on the operator panel or when the service processor has detected a server problem (such as a surveillance failure).
