    摘要: A data processing system including an automated storage library (1) for which the management thereof is transparent to a requester is disclosed. A system controller in the library provides the internal management of the library. To access a file in the library, a requester need only specify to the system controller the volume on which the file is located, permitting the use of a standard file access method for a single peripheral storage device. A path format which is the same as that used for a single, peripheral storage device, except that the peripheral storage device designator is replaced with a designator (35) for the automated storage library (1) and a volume label (36) is inserted as a subdirectory path element. The system controller determines, independently of the data processing system, which peripheral storage device a data storage medium is to be mounted in.

    摘要: An error detecting and recovery subsystem which can be easily modified for use with any data processing system which is being monitored is disclosed. The subsystem employs a user editable file including the rules for defining the system state, the error states, and the sequences of recovery actions to be taken depending upon the comparison between the system state and the error states. The rules for defining the system state, include means for determining selected system variables, and the sequences of recovery actions are specified using an index into a set of elemental recovery actions. Because the system state, error state, and sequence of recovery actions are defined in a user editable file, modifications to the error detection and recovery scheme can be made without recompiling the recovery subsystem program code. Such modifications to the subsystem may therefore be made on a real time basis.

    摘要: A method for servicing a mount request in an automated storage library (1) in which all of the peripheral storage devices (4) therein are occupied and which permits an active data storage medium to be temporarily demounted and subsequently remounted in any subsequently available peripheral storage device is disclosed. To service a mount request requiring that a data storage medium be demounted, the access information for the data storage medium to be demounted is first retained. After demounting and servicing of the mount request, the retained access information is used to permit remounting of the previously mounted data storage medium in any subsequently available peripheral storage device, thereby minimizing the risk of delay in remounting. The method also allows for optional parameters to prevent temporary demounting in an automated storage library, or to prevent temporary demounting of particular data storage media. The method allows access to more data storage media than there are peripheral storage devices by temporarily demounting the least recently used data storage media.
