Maintenance control method, system control apparatus and storage medium

A maintenance control method executed by a processor of a system control apparatus to execute a process, the maintenance control method comprising:

• classifying, by referring to correspondence information in which information indicating a virtual machine, a desired time zone for executing a maintenance operation of a physical machine are associated with each other for each of the plurality of virtual machines, a plurality of virtual machines into a plurality of groups based on the desired time zone, an overlap time of one or more desired time zones corresponding to one or more virtual machines included in each of the plurality of groups being equal to or longer than a predetermined time;
• mapping, for each of the plurality of groups, the one or more virtual machines to one of the plurality of physical machines such that mapping destinations for the plurality of groups are different from each other;
• and
• executing, for each of the plurality of groups, the maintenance operation in a time zone corresponding to the overlap time.

A system control apparatus, comprising

• a memory;
• and
• a processor coupled to the memory and configured to:
• classify, by referring to correspondence information in which information indicating a virtual machine, a desired time zone for executing a maintenance operation of a physical machine are associated with each other for each of the plurality of virtual machines, a plurality of virtual machines into a plurality of groups based on the desired time zone, an overlap time of one or more desired time zones corresponding to one or more virtual machines included in each of the plurality of groups being equal to or longer than a predetermined time,
• map, for each of the plurality of groups, the one or more virtual machines to one of the plurality of physical machines such that mapping destinations for the plurality of groups are different from each other, and
• execute, for each of the plurality of groups, the maintenance operation in a time zone corresponding to the overlap time.
