Embodiment Construction

[0012] Referring to FIG. 1, there is shown a general-purpose system that can function as a basic data processing system on which the present invention can be implemented. This system is an exemplary data processing system that can be used with any server or computer in the preferred embodiment of the present invention. The CPU 10 is provided and connected to other various components through a system bus 19 . During system operation, an operating system 40 is connected to random access memory (RAM) 14 . Operating system 40 may be a commercially available operating system capable of single or multiprocessing, such as AIX from IBM Corporation TM Operating system, Microsoft Windows XP TM and UNIX TM operating system. System controlled applications 41 can be moved in and out of main memory RAM 14 . These applications may include programs for implementing the present invention, which are described in more detail below. It should be noted that the program logic and methods of t...

Abstract

A system and method for an initial boot of a system before adding or removing drawers to a system without requiring an n-level cable. Standby power is applied after all cables have been connected to the system. All available expansion ports for an SMP cable are searched. A unique ID is sent over and received by all plugged SMP cables. A list of each controller and its connected controllers is created, and a master controller is assigned. A plugging table of each controller is sent to the master controller. The master controller compares all received plugging tables to plugging rules. Errors are reported in cable plugging errors and system configuration is reported to platform management service.

Description

technical field [0001] The present invention relates to a system and method for simultaneously adding new drawers to the system. More specifically, the present invention relates to methods, apparatus and products for initial booting prior to adding or removing drawers to a system without requiring n-level cables. Background technique [0002] One current server design involves a system of small building blocks called "drawers." A coherent fabric between drawers is connected using dedicated cables to form a single symmetric multiprocessing (SMP) system. With the advent of multi-drawer systems, systems now have the ability to plug in 1 to n individual drawers in a single system that will serve as processors, memory, and I / O. This configuration requires each drawer to be part of a single control entity, requiring dedicated n-level cables for each specific configuration. The class n cables involved here are architectural cables found in most large SMP server systems today. T...
