FIRMWARE UPDATE APPARATUS AND STORAGE CONTROL APPARATUS |
| 摘要 |
A storage unit stores information on the compatibility between different versions of firmware used for controlling two redundant modules provided in a storage apparatus. Upon updating firmware of the modules from a first version to a second version incompatible with the first version, a computing unit applies, alternately to one of the modules, firmware of a version that is one of versions from the first version to the second version, that is compatible with firmware of a version currently applied to the other one of the modules, and that is more recent than the version currently applied to the other one of the modules, by referring to the information. |

1. A firmware update apparatus comprising:
a memory that stores information on compatibility between different versions of firmware used for controlling two redundant modules provided in a storage apparatus; and a processor that performs a procedure including: upon updating firmware of the two modules from a first version to a second version incompatible with the first version, applying, alternately to one of the modules, firmware of a version that is one of versions from the first version to the second version, that is compatible with firmware of a version currently applied to the other one of the modules, and that is more recent than the version currently applied to the other one of the modules, by referring to the information. |
