CONTROL METHOD FOR CALCULATOR, CALCULATOR SYSTEM, AND STORAGE MEDIUM

摘要

A management calculator reads data in a first disk volume, determines whether or not an error occurs when reading the data in the first disk volume, writes the read data into a second disk volume to generate a replication when determining that the error does not occur, writes the position of the read data into defective block management information when determining that the error occurs, assigns the second disk volume to a calculator, and transmits the defective block management information to the calculator, and the calculator refers to the received defective block management information when accessing the second disk volume, and causes an error when the position to be accessed matches the defective block management information.
