Device driver error isolation on devices wired via fsi chained interface

A computer system comprising:

• a plurality of electronic devices including one or more processing units and one or more memory devices, at least two of the electronic devices being field replaceable units;
• a plurality of links interconnecting said electronic devices including at least two serial interfaces having an identical interface design adapted for interconnecting said field replaceable units;
• and
• at least one device driver for controlling one of said electronic devices wherein said device driver detects an error in the computer system, analyzes the error using fault isolation logic to determine first failure data and a logical error identifier for the error representing a hardware logical area of a fault which caused the error, and maps the fault to a segment of the computer system using the first failure data and the logical error identifier based on a self-describing system model for the computer system which is stored in one of said memory devices.

A computer program product comprising:

• a computer readable storage medium;
• and
• a device driver comprising program instructions residing in said storage medium, said program instructions including:
• standard instructions for controlling operations of an electronic device of a computer system which detect an error caused by a fault in the computer system wherein the electronic device is one of a plurality of electronic devices including field replaceable units interconnected by serial interfaces adapted for interconnecting said field replaceable units, and
• fault isolation logic which analyzes the error to determine first failure data and a logical error identifier for the error representing a hardware logical area of a fault which caused the error, and maps the fault to a segment of the computer system using the first failure data and the logical error identifier based on a self-describing system model for the computer system.
