INFORMATION PROCESSING SYSTEM AND VIRTUAL ADDRESS SETTING METHOD

An information processing system includes an information processing apparatus, which includes an arithmetic processing unit and a control device that is connected to the arithmetic processing unit, and includes a management device that manages a virtual address. When a communication abnormality occurs between the management device and the control device, the management device instructs the control device to perform a start via the arithmetic processing unit. When the control device is instructed by the arithmetic processing unit to perform a start, the control device transfers the virtual address stored in a storing unit to the arithmetic processing unit. When the arithmetic processing unit receives the virtual address from the control device, the arithmetic processing unit sets a port included in the arithmetic processing unit to the virtual address.
