A disk array apparatus has a plurality of the same type of disk array units. Each of the disk array units has a plurality of storage areas in each of which firmware for allowing the disk array unit to operate is stored. When the disk array apparatus recognizes that a first disk array unit has been disposed therein, it compares a version number of firmware stored in each storage area included in the first disk array unit with a version number of firmware stored in each storage area included in a second disk array unit that currently operates in the disk array apparatus. If these version numbers are the same, the disk array apparatus makes a storage area in which firmware executed by the first disk array unit is stored conform to a storage area in which firmware executed by the second disk array unit is stored.

A statistically added point calculation unit of the present invention statistically adds a point to a part related to a content of an anomaly in error information received by an error information receiving unit, and sets the added point in an added point table. A suspected place identifying unit refers to the added point table, and if the statistically added point of a target of determination has exceeded a threshold, the suspected place identifying unit identifies the target of the determination as a suspected place. If the configuration information table is referred to and a target of this process is a maintenance part at the suspected place, the suspected place identifying unit compares an initial value, for example, by means of the threshold which has been doubled. Furthermore, the suspected place identifying unit identifies a part having the statistically added point which is the next highest, as a second suspected place. A part isolation processing unit isolates the part at the suspected place. A configuration information management unit sets a second suspected place flag at the corresponding part in the configuration information table.

Suspected place identifying apparatus and processing method

A failure-data register unit receives failure data from a failure detecting module. Based on the failure data, a test-execution instructing unit instructs each module to execute access tests for the module accessed when the failure detecting module detected the failure. When a test-result receiving unit receives results of the access tests, a failure-location identifying unit identifies the failed module based on the results. A server-request control unit suspends server I/O while the access tests are performed.
