Library system, management apparatus, library apparatus, management method, and management program for managing data storage media

摘要

In a library system, a library apparatus detects replacement of a first drive by a second drive. The library apparatus sends management data describing the replacement of the first drive to a management apparatus. Based on relationships between the management data and storage media accommodated in the library apparatus, the management apparatus determines which of the storage media is to become unusable for reading data or writing data or both reading and writing data. The determined storage medium is designated as a migration source medium. The management apparatus then sends a data migration command to initiate data migration from the migration source medium to another storage medium. In response, the library apparatus migrates data from the specified migration source medium to another storage medium, based on the migration source information.
