Abstract
A system for testing logical partitioning. In a preferred embodiment, an I/O adapter is configured to break partitioning rules, for example, to attempt to access addresses outside a valid address range. Software is used to check for expected errors at expected addresses. If expected errors are not found, a fault in the partitioning I/O subsystem is indicated.
