Further, it is preferable that a storage means is provided for storing all contents corresponding to the contents of the error log file, and the display means is configured to display the contents of the storage means.

[Effect]

Error information indicating failures occurring at key points in the logical unit is collected, analyzed, and stored along with FRU name information. When the error repair is completed, the memory of the corresponding error information and FRU name information is erased and is not displayed. Therefore, there is no need to make it difficult to distinguish between information indicating a resolved failure and information indicating a newly occurring failure on the display screen.
