Knowledge based resource management
First Claim
1. Apparatus for controllably isolating operational elements in a customer system, which customer system includes a plurality of operational elements, each interconnected to at least one other operational element via an interconnection path, comprising:
- means for storing data identifying all said operational elements and said interconnection paths;
means for detecting the presence of a failure in said associated customer system;
means for generating a failure report which contains data relevant to said detected failure, including an identification of the failure mode and, exclusively, all said operational elements that were cooperatively operative and active during said detected failure;
means for retrieving a portion of said data from said storing means to identify a subset of said operational elements and all said interconnection paths connected to said subset of operational elements; and
means for selectively disabling the use of said subset of operational elements, as identified by said retrieving means, by said customer system, comprising;
means for determining whether disabling said subset of operational elements reduces a number of available operational elements below a predetermined threshold; and
means, responsive to said number being above said threshold, for fencing said subset of operational elements by disabling any said interconnection paths connected to said subset of operational elements.

Abstract
The knowledge based system identifies the occurrence of a failure within the customer equipment and functions using its rules, hypotheses and collected data to isolate the functional resource which is the source of the error in the customer equipment and, whenever possible, "fence" or isolate the failed functional resource that has caused the error. In addition, the knowledge based system makes use of resource related rules to remove a resource or set of resources available for concurrent other failure management operations. The resource related rules allow resources to function in any one non-operational or operational mode or to functional simultaneously in multiple non-operational modes.

8. A method for controllably isolating operational elements in a customer system, which customer system includes a plurality of operational elements, each interconnected to at least one other operational element via an interconnection path, comprising the steps of:
-
storing data in a memory to identify all said operational elements and said interconnection paths; detecting the presence of a failure in said associated customer system; generating a failure report which contains data relevant to said detected failure, including an identification of the failure mode and, exclusively, all operational elements that were cooperatively operative during said detected failure; retrieving a portion of said data from said memory to identify a subset of said operational elements and all said interconnection paths connected to said subset of operational elements; and selectively disabling the use of said subset of operational elements, as identified by said step of retrieving, by said customer system, comprising; determining whether disabling said subset of operational elements reduces a number of available operational elements below a predetermined threshold; and fencing, in response to said number being above said threshold, said subset of operational elements by disabling any said interconnection paths connected to said subset of operational elements. - View Dependent Claims (9, 10, 11, 12, 13, 14)
