摘要： In an automated storage library (1), demount of data storage media may be permitted when all peripheral storage devices (4) in the library are occupied and one or more of such devices remains inactive for a predetermined time. Storage media may be demounted to carry out a mount request, provided that the peripheral storage devices in which the media are mounted are inactive. Even when no mount requests are pending, the status of the peripheral storage devices is continually monitored. If the peripheral storage devices are all occupied, and one or more of such devices remains inactive for the predetermined time, the least recently used storage medium is demounted and transferred to a storage cell in the library. Demount of storage media may also be permitted when one or more of the occupied peripheral storage devices remains inactive for a relatively long predetermined time. Storage media may be demounted to carry out a mount request, provided that the peripheral storage devices in which the media are mounted are inactive. A storage medium may also be demounted to create an unoccupied peripheral storage device, even though no mount request is pending, when all of the peripheral storage devices are occupied and one or more of such devices remains inactive for a relatively short predetermined time. Regardless of the existence of a pending mount request or of the occupancy status of the peripheral storage devices, the storage medium in each of the occupied peripheral storage devices remaining inactive for the relatively long predetermined time is demounted and transferred to a storage cell in the library. Thus, during long idle periods, the library will not continue to use the resources of inactive peripheral storage devices.

摘要翻译： 在自动存储库（1）中，当库中的所有外围存储设备（4）被占用并且这些设备中的一个或多个在预定时间内保持不活动时，可允许拆卸数据存储介质。 可以拆卸存储介质以执行安装请求，条件是其中安装介质的外围存储设备不活动。 即使没有安装请求处于挂起状态，也会不断监视外围存储设备的状态。 如果外围存储设备都被占用，并且这些设备中的一个或多个在预定时间内保持不活动，则最少使用的存储介质被拆卸并传送到库中的存储单元。 当一个或多个被占用的外围存储设备在相对较长的预定时间内保持不活动时，也可以允许存储介质的拆卸。 可以拆卸存储介质以执行安装请求，条件是其中安装介质的外围存储设备不活动。 即使所有外围存储设备被占用并且这些设备中的一个或多个在相对较短的预定时间内保持不活动，即使没有安装请求正在等待，也可以拆卸存储介质以创建未占用的外围存储设备。 不管存在挂起请求或外围存储设备的占用状态，每个被占用的外围存储设备中的存储介质在相对较长的预定时间内保持不活动，并被传送到库中的存储单元 。 因此，在长时间闲置期间，库将不会继续使用非活动外设存储设备的资源。
