Abstract
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.

An apparatus for identifying a failure module in a disk controller that includes a plurality of modules, the apparatus comprising:
- a test-instructing unit that instructs, when one of the modules detects a failure, the modules to execute an access test to a memory with test data;
- and
- an identifying unit that identifies a module where the failure occurred based on results of the access test.
