PROBLEM TO BE SOLVED: To provide an array disk group maintenance management system, an array disk group maintenance management device, an array disk group maintenance management method, and an array disk group maintenance management program, for dynamically changing a criterion for preventive replacement of array disks for each generation of the array disks. SOLUTION: In the array disk group maintenance management device 1, a transmitting and receiving part 11 receives log information from a disk device 2, a fault count information acquisition part 12 acquires information on the number of faults information based on the log information, a failure rate calculation part 13 calculates a failure rate of an array disk 101 of each generation based on the acquired fault count information; a threshold update part 14 updates a frequency threshold for recovery error of the array disk 101 of each generation based on the calculated failure rate of the array disk 101. The transmitting and receiving part 11 transmits the updated threshold information for recovery error to the disk device 2. COPYRIGHT: (C)2008,JPO&INPIT
