摘要： PROBLEM TO BE SOLVED: To determine a life of a magnetic disk accurately by monitoring an energizing time of the magnetic disk and a frequency of occurrence of an error caused by various factors, and to prevent data loss due to an end of the life of the magnetic disk by displaying the determined result stepwise.
SOLUTION: A life managing system for a magnetic disk device that manages the life of the magnetic disk device 5, has: a first storing section 55 that stores as a log 51, updated information on the energizing time of the magnetic disk device 5 and the number of errors which are malfunctions caused by an operation of the magnetic disk device 5; a second storing section 31 that stores a life prescription table 32 in which a residual life of the magnetic disk device 5 is prescribed in advance according to the energizing time and the number of errors; and a control section 35 that determines the residual life of the magnetic disk device 5 based on the log 51 read from the first storing section 55 and the life prescription table 32 stored in the second storing section 31.

摘要： PROBLEM TO BE SOLVED: To manage and control a status in a disk array by use of error information on other than a disk array controller and an HDD as well, thereby preventing deterioration in performance of a host, a system failure, and extension of maintenance time.
SOLUTION: An internal status determining unit 21 reads a command recording table 23, and displays a status in a display device 30 according to an internal status table 22. An error frequency and a process time threshold value are determined, and if a threshold value is exceeded, error information is received from a BMC 11. If there is no error information, a disk control unit 24 degenerates an HDD or issues a warning by a buzzer 12. A command being processed by an external trigger 31 is terminated and an error is transmitted to the host.

摘要： PROBLEM TO BE SOLVED: To provide a disk array device, for improving reliability by managing error information of a disk and automatically checking consistency.
SOLUTION: In this disk array device, a disk management table recording error occurrence positions and error occurrence dates of the disk and period-based totals is held. When a preset threshold or a threshold set by a user for the information of the management table is exceeded, consistency check is automatically performed, and a message for urging preventive maintenance of the disk is displayed.
