System and method for thresholding system power loss notifications in a data processing system based on current distribution network configuration
First Claim
1. A computer program product comprising a computer useable storage medium having a computer readable program stored thereon, wherein the computer readable program, when executed on a data processing system, causes the data processing system to:
- determine a configuration of a data processing device within the data processing system;
determine a current power distribution network configuration relative to the data processing device based on the determined configuration of the data processing device within the data processing system, in response to a power supply module of the data processing system asserting an Early Power Off Warning (EPOW) signal; and
assert a power loss notification signal, indicative of an imminent power loss to the data processing device, to logic of the data processing system based on the determined current power distribution network configuration relative to the data processing device.

Abstract
Mechanisms for thresholding system power loss notifications in a data processing system are provided. Power loss detection modules are provided in a data processing system having one or more data processing devices, such as blades in an IBM BladeCenter® chassis. The power loss detection modules detect the type of infrastructure of the data processing system, a position of a corresponding data processing device within the data processing system, and a capability of the data processing system to provide power during a power loss scenario. The detection module detects various inputs identifying these types of data processing system and power system characteristics and provides logic for defining a set of behaviors during a power loss scenario, e.g., behaviors for sending system notifications of imminent power loss. The detection of the various inputs and the defining of a set of behaviors may be performed statically and/or dynamically.
