ABSTRACT:
A method, apparatus, and computer instructions for recovering terminated partitions in a logical partitioned data processing system. A termination of a partition in a set of partitions associated with a host bridge in the logical partitioned data processing system is detected. The state of other partitions within the set of partitions is checked in response to detecting the termination. A recovery process is initiated if all partitions in the set of partitions have terminated. Input/output slots associated with the host bridge are reset to a normal state if the recovery process is successful. The set of partitions is rebooted after resetting the input/output slots associated with the host bridge without rebooting the logical partitioned data processing system.
