Abstract
A system, method, and computer program product are disclosed for executing a reliable warm reboot of one of multiple partitions included in a logically partitioned data processing system. The data processing system includes partition hardware. A request to reboot a particular partition is received within the partition where the particular partition includes multiple processors. Prior to executing the reboot request, the partition hardware is set to a predetermined state. The reboot request is then executed within the particular partition. The predetermined state is preferably achieved by resetting the partition hardware to a predetermined state.
