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.
Claims6
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 of the partitions is configured by one or more system boards, the method comprising:
- storing a version of firmware used in each partition in association with the each partition in a partition-specific version storage 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;
- 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;
- storing board identification information for identification of the system board in a system board configuration information storage unit;
- and
- storing firmware of a latest version in a latest version storage unit;
- wherein
- when a new partition is set and a new system board is used, board identification information about the newly used system board is compared with board identification information stored in the system board configuration information storage unit and it is determined whether or not the system board has not been registered, and when the newly used system board has not been registered, the firmware of the newly used system board is changed to the firmware of the latest version stored in the latest version storage unit.
An information processing device having a plurality of partitions in which a plurality of operating systems can be operated, each of the partitions being configured by one or more system boards in which firmware is implemented, comprising:
- a partition-specific version storage unit storing a version of firmware used in each partition in association with the each partition;
- 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;
- a system board configuration information storage unit storing board identification information for identification of the system board;
- and
- a latest version storage unit storing firmware of a latest version, wherein
- when a new partition is set and a new system board is used, the version change unit compares board identification information about the newly used system board with the board identification information stored in the system board configuration information storage unit, determines whether or not the system board has not been registered, and when the newly used system board has not been registered, changes the firmware of the newly used system board to the firmware of the latest version stored in the latest version storage unit.
