Determining the source of failure in a peripheral bus
First Claim
1. A system to determine a cause of failure in a peripheral bus, said peripheral bus holding multiple PC cards, and where said peripheral bus is connected by a bridge chip to a processor bus, comprising:
- a) a lost heartbeat detector detecting lost heartbeats from each of the multiple PC cards held by the peripheral bus;
b) said lost heartbeat detector sending a signal to a PC card failure detector when said PC card heartbeat is lost;
c) said lost heartbeat detector sending a signal to the bridge chip failure detector when said PC card heartbeat is lost; and
d) said lost heartbeat detector generating a data table registering said lost heartbeats.

Abstract
Many computing system environments require continuous availability and high operational readiness. The ability to find, diagnose, and correct actual faults and potential faults in these systems is a high priority. By combining a continually updated database of computing system performance with the ability to analyze that information to detect faults and then communicating that fault information to correct the fault or provide appropriate notification of the fault results in achieving the goals of high availability and operational readiness. FIG. (1) shows how the data collectors, fault detectors and policy actions are combined to meet those goals.
