Program redundancy among virtual machines and global management information and local resource information arrangement

An apparatus management method performed by an information processing apparatus that includes a first system board including a first processor and a second system board including a second processor, the first processor or the second processor operating as a virtualization control unit, which operates virtual machines by virtualizing hardware resources included in the first system board and the second system board, the apparatus management method comprising:

• first storing, in a first storing unit included in the first system board,
• first resource information, which is information used by the first processor operating as the virtualization control unit by executing a program text, and, in a management information storing unit included in the first system board, management information including information about the system boards included in the information processing apparatus, the information being commonly shared by each of the system boards among information used when the virtualization control unit operates;
• and
• second storing, in a second storing unit included in the second system board, second resource information, which is information used by the second processor operating as the virtualization control unit by executing the program text,
• wherein the virtualization control unit performs an initialization process including:
• storing the program text in the first storing unit and the second storing unit, the program text including an initialization program, and
• making the first processor and the second processor respectively execute in parallel the initialization program stored in the first storing unit and the second storing unit, wherein in the initialization process, the first processor stores in the first storing unit, as the first resource information, information that associates the hardware resources included in the first system board and virtualized hardware resources, the second processor stores in the second storing unit, as the second resource information, information that associates the hardware resources included in the second system board and virtualized hardware resources, and the first processor stores in the management information storing unit, as the management information, storing locations of the first resource information and the second resource information and
• wherein when the second processor executes a command read from the program text stored in the second storing unit, and when information referred to by the command is not stored in the second resource information in the second storing unit, the second processor refers to the management information stored in the management information storing unit.

A non-transitory computer readable storage medium having stored therein an apparatus management program causing an information processing apparatus that includes a first system board including a first processor and a second system board including a second processor, the first processor or the second processor operating as a virtualization control unit, which operates virtual machines by virtualizing hardware resources included in the first system board and the second system board, to execute a process comprising:

• first storing, in a first storing unit included in the first system board, first resource information, which is information used by the first processor operating as the virtualization control unit by executing a program text, and, in a management information storing unit included in the first system board, management information including information about the system boards included in the information processing apparatus, the information being commonly shared by each of the system boards among information used when the virtualization control unit operates;
• and
• second storing, in a second storing unit included in the second system board, second resource information, which is information used by the second processor operating as the virtualization control unit by executing the program text,
• wherein the virtualization control unit performs an initialization process including:
• storing the program text in the first storing unit and the second storing unit, the program text including an initialization program, and
• making the first processor and the second processor respectively execute in parallel the initialization program stored in the first storing unit and the second storing unit, wherein in the initialization process, the first processor stores in the first storing unit, as the first resource information, information that associates the hardware resources included in the first system board and virtualized hardware resources, the second processor stores in the second storing unit, as the second resource information, information that associates the hardware resources included in the second system board and virtualized hardware resources, and the first processor stores in the management information storing unit, as the management information, storing locations of the first resource information and the second resource information, and
• wherein when the second processor executes a command read from the program text stored in the second storing unit, and when information referred to by the command is not stored in the second resource information in the second storing unit, the second processor refers to the management information stored in the management information storing unit.
