Abstract
Proposed is a storage apparatus capable of alleviating the burden of maintenance work when a failure occurs in a part configuring the storage apparatus. This storage apparatus includes multiple disk drives and spare disk drives, and multiple controllers. When a failure occurs, this storage apparatus determines the operability status of the storage apparatus based on failure information. When operation can be continued, the storage apparatus continues to operate without performing any maintenance such as part replacement, and if operation cannot be continued, data is migrated to another storage apparatus.
