An information processing apparatus includes a degeneration control unit and a re-synchronization processing instructing unit. The degeneration control unit degenerates, of a first controller group including a first controller and a second controller group including a second controller, the second control device group when the first and second controller performing a synchronization operation with each other detect occurrence of errors. The re-synchronization processing instructing unit instructs a controller included in the first controller group to execute re-synchronization processing. When another controller different from the first controller receives the instruction for the execution of the re-synchronization processing, the another controller performs interrupt mask setting. When the first controller receives the instruction for the execution of the re-synchronization processing, the first controller withholds the execution of the re-synchronization processing, starts error processing, and instructs the controller that performs the interrupt mask setting to release the interrupt mask.
