摘要: A system, a method, and computer program product to provide failover procedure for an automated data storage library are provided. During the operation of library, host issues control commands using one or more paths. In event that does not receive desirable results, such as when communication is lost between while command in process, may attempt retry same path alternate path. When command, performs examination previous executed prevent from executing identical than once.
