Management device, data acquisition method, and recording medium

A data acquisition method:

• managing an information processing apparatus that performs a memory access by using a conversion table in which an absolute address that is used by an processor to specify data is associated with a physical address that indicates a storage area in a memory, by the processor;
• saving, when the information processing apparatus has failed, the conversion table, by the processor;
• creating, by using the saved conversion table, 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, by the processor;
• setting the created second conversion table in the information processing apparatus, by the processor;
• and
• acquiring, by using the set second conversion table, the data from the storage area that is indicated by the physical address associated with the standby absolute address, by the processor.

A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute a data acquisition process comprising:

• saving, when an information processing apparatus that performs a memory access by using a conversion table in which an absolute address that is used by an processor to specify data is associated with a physical address that indicates a storage area in a memory has failed, the conversion table;
• creating, by using the saved conversion table, 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 created second conversion table in the information processing apparatus;
• and
• acquiring, by using the set second conversion table, the data from the storage area that is indicated by the physical address associated with the standby absolute address.
