行ないファイルの自動復旧を行なうことを特徴とする。The configuration of the disk failure automatic recovery method of the present invention monitors the number of input/output errors in error log files, and when the number of input/output errors exceeds a specified value, automatically analyzes the cumulative error log file and automatically starts each application tool. It is characterized by monitoring and automatically restoring files.
