INFORMATION PROCESSING APPARATUS, CONTROL METHOD FOR THE INFORMATION PROCESSING APPARATUS, AND RECORDING MEDIUM

摘要

Even when a main board is replaced, if no change is made to a connected storage unit, existent mirroring information is obtained to resume mirroring function processing. An information processing apparatus that performs mirroring to store same data in a plurality of storage units includes a first storage unit configured to store mirroring information indicating a state of the mirroring in a memory of a main board, a second storage unit configured to store the mirroring information in a memory of a sub board, a detection unit configured to detect replacement of the main board, and a restoration unit configured to restore the mirroring information stored in the memory of the sub board by the second storage unit in a memory of a replaced main board in accordance with detection of the replacement of the main board by the detection unit.
