摘要：
The present invention proposes a disk array apparatus that can be inexpensively constructed while maintaining its high reliability, and also proposes a method for controlling the disk array apparatus, and a program. In the disk array apparatus, a storage area in a storage device for storing system information is managed by dividing the storage area into a system area for storing system information and a data area for storing data from a host device, and verification processing is executed on the data area in the storage device in a first cycle and on the system area in a second cycle that is shorter than the first cycle.
