Chapter 7. Using the Service ProcessorNotes:1. On some of the system management services (or service processor) screens, you will see the termLPAR, which is equivalent to the term logical partition. This system does not support logical partitions.2. The information in this chapter regarding the configuring of serial ports, and modems attached to thoseserial ports, applies only to the serial ports (S1, S2 and S3) on the service processor (locationU0.1-P1-X1). None of this information is applicable to the serial ports, or modems attached to thoseserial ports on the HMC.The service processor runs on its own power boundary and continually monitors hardware attributes andthe environmental conditions within the system. The service processor is controlled by firmware and doesnot require the operating system to be operational to perform its tasks.The service processor menus allow you to configure service processor options, as well as enable anddisable functions.Service processor menus are available using an ASCII terminal or an HMC virtual terminal window whenOK is displayed on the operator panel or when the service processor has detected a system problem (suchas a surveillance failure).Service Processor MenusThe service processor menus are divided into the following groups:v General user menu - the user must know the general-access password.v Privileged user menus - the user must know the privileged-access password.If the system is powered off, the service processor menus can be accessed locally or remotely on thefollowing:v Serial port 1 (S1)v Serial port 2 (S2)v HMCAccessing the Service Processor Menus LocallyService processor menus can be accessed by opening a virtual terminal window on the HMC, or byattaching an ASCII terminal to serial port 1 (S1) or serial port 2 (S2). After OK displays in the operatorpanel, press any key on the keyboard to signal the service processor.Notes:1. The service processor menus cannot be accessed simultaneously on a virtual terminal window on theHMC and on an ASCII terminal. Accessing the menus on the HMC locks out access to the ASCIIterminals and vice versa.2. When the system is connected to an HMC and a virtual terminal window is open, providing aconnection to the managed system, serial port 1 is used by the HMC and is not available to thefunctions that are normally provided by the service processor. Those functions include the ring-indicatepower-on, console mirroring, serial port snooping and call-in/call-out.When you gain access, the service processor prompts you for a password (if one is set), and whenverified, displays the service processor menus.The service processor menu prompt, represented by 0> or 1>, indicates the serial port to which theterminal is connected.v An ASCII terminal can have the following prompts:225
