Abstract: A management device includes a processor that executes a process. The process includes: saving a conversion table when an information processing apparatus that performs a memory access by the conversion table, in which an active absolute address that is used by the processor to specify data is associated with an active physical address that indicates a storage area in a memory that stores therein the data, has failed; creating a second conversion table in which a standby absolute address that is different from the active absolute address is associated with the active physical address used at the time of a failure and a standby physical address that is different from the active physical address used at the time of the failure is associated with the active absolute address; setting the second conversion table; and acquiring the data from the storage area that is indicated by the physical address.
