System, method, and computer program product for preserving trace data after partition crash in logically partitioned systems

摘要

A system, method, and product in a logically partitioned data processing system are disclosed for preserving trace data after a partition crash. The logically partitioned data processing system includes multiple, different processors. An error is encountered in one of the processors. Data associated with the error is stored in a trace buffer. Contents of the trace buffer are stored prior to the data being overwritten.
