ABSTRACT:
A method, system, and computer program product are disclosed for improving isolation of I/O errors in logical partitioned data processing systems. A machine check is generated that indicates that an I/O error has occurred in the system. The PCI host bridge (PHB) that generated the machine check is identified. The system includes multiple PHBs, each with its own set of slots. Some of these slots may be enabled for enhanced error handling while others of them are not. The adapters that are not enabled for enhanced error handling and that are coupled to the PHB that generated the machine check are identified. It is then determined that the I/O error occurred in at least one of these slots that are not enabled for enhanced error handling.
