Abstract
Automated update to the firmware of the optimum version can be performed when a system board is exchanged, etc. When a system board is exchanged, a version change unit compares the version of the firmware of the system board with the version of the firmware of the corresponding partition stored in the partition-specific version storage unit. When they do not match, the version of the firmware of the system board is updated to the same version stored in the partition-specific version storage unit.
Claims11
A firmware version managing method of a system board of a computer system having a plurality of partitions in which a plurality of operating systems can be operated, and each partition is configured by one or more system boards, wherein:
- a version of the firmware used in each partition is associated with each partition and stored in a partition-specific version storage unit;
- and
- when the system board is exchanged, it is determined whether or not a version of the firmware of a newly used system board matches a version of the firmware of a corresponding partition stored in the partition-specific version storage unit, and when the versions do not match, the firmware of the newly used system board is changed to a same version as the firmware of the partition stored in the partition-specific version storage unit.
An information processing device having a plurality of partitions in which a plurality of operating systems can be operated, each partition being configured by one or more system boards in which firmware is implemented, comprising:
- a partition-specific version storage unit storing a version of the firmware used in each partition associated with each partition;
- and
- a version change unit determining, when the system board is exchanged, whether or not a version of the firmware of a newly used system board matches a version of the firmware of a corresponding partition stored in the partition-specific version storage unit, and changing, when the versions do not match, the firmware of the newly used system board to a same version as the firmware of the partition stored in the partition-specific version storage unit.
