ABSTRACT:
An information processing system has a processor, a first storage unit, a controller connected between said processor and said first storage unit, and a second storage unit connected to said processor and for storing dump data, and a dump method thereof are disclosed. The controller manages updated regions of the first storage unit as write regions. In response to a dump request issued by the processor, the controller manages regions which are managed as the write regions and included in a dump portion as protected regions. If a write request for a region which is managed as protected region, the controller saves contents of the region to dump point file before executing a write operation, and release the region from the protected regions. The controller transfers contents of regions managed as protected track and contents of the dump point file to the processor as contents of regions to be dumped. At the end of dump processing, the controller deletes the dump point file and terminates management of the protected regions.
