摘要： Disclosed is a system, method, and program for accessing a data set, e.g., volume, file, from one of two storage devices. Each storage device includes a copy of the data set. A flag is maintained for each storage device indicating whether a previous access attempt of the data set from the storage device failed. The storage device having the flag indicating that no previous access attempt failed is selected if the flag for the other storage device indicates that one previous access attempt of the data set from the storage device failed. The data set is accessed from the selected storage device.

摘要： A system, apparatus, and method to recover a logical volume on a read-only physical volume, or data storage cartridge, within a dual copy data storage system, such as a virtual tape server (VTS) system. The recovery follows a disaster situation involving the primary physical volume and the requested logical volume. The system, apparatus, and method include modules and steps as required to recover a logical volume through recalling a selective dual copy of the logical volume stored on a secondary physical volume. The primary and secondary logical volumes are stored on distinct physical volumes in order to provide quality storage media management and reduce the likelihood of loss of data. The recovery and recall procedures are implemented in a manner that is substantially transparent and asynchronous to a host or client. Additionally, the recovery and recall require no additional input from the host in order to carry out the recovery of the logical volume.

摘要： A data storage system stores data with a corresponding encapsulated metadata token in cache and/or base storage to protect against recalling stale data from base storage in the event of a cache failure and subsequent cache miss. A controller is coupled to a cache, base storage, and token database. After receiving a data object and associated write request, the controller assigns a version code to the data object. If the data object already exists, the controller advances the data object's version code. A token, including the version code along with other items of metadata, is encapsulated for storage. Then, the controller stores the data object and encapsulated token in cache and/or base storage and updates the token database to cross-reference the data object with its version code. When the controller experiences a cache miss, there is danger in blindly retrieving the data object from base storage since the cache miss may have occurred due to cache failure before the data was de-staged, leaving a down-level version of the data object on base storage. This problem is avoided by comparing the data object's version code contained in base storage to the version code listed for the data object in the token database. Only if the compared version codes match, the data object is read from base storage and provided as output.

摘要： Disclosed are a data storage library subsystem, and a method which may be implemented by a computer program product, for increasing the accessing performance of data volumes from libraries in a redundant copy synchronization token tracking system. The libraries store redundant copies of the data volumes, and have cache storage and backing storage. Updatable synchronization tokens indicate the relative update levels of the redundant copies. Each library maintains the synchronization token directly associated with each data volume; identifies each of the data volumes upon being stored in the cache storage of the library; and identifies each of the data volumes migrated to and stored in the backing storage of the library. Then, the library responds to a recall request for one of the redundant copies, providing, with the synchronization token, an indicator whether the data volume is identified as stored in the cache storage or the backing storage. The performance of the accessing is increased by a selection of a redundant copy of the data volume identified as stored in the cache storage rather than a copy identified as stored in the backing storage.

摘要： A removable media storage library comprises a plurality of removable media divided into a plurality of sets, each set associated with its own server. A central manager controls access to all of the removable media. Each of the servers and library manager contain database map information. If this information is lost, a selected disaster recovery operation may be implemented. This flexibility in selecting the type of disaster recovery operation allows for an efficient and fast disaster recovery operation.

摘要： A method and apparatus for improving caching for a virtual tape server is disclosed. The method and apparatus improve caching by making assumptions to increase cache hits, but which do not cause the virtual tape server to under-perform when these assumptions prove to be incorrect. The method includes the steps of correlating logical volume usage to externally determined file characteristics to derive usage histories for cached logical volumes, maintaining a record of the histories for the files that share the same predefined characteristics, and managing the migration of the logical volumes according to the usage history and the externally determined file characteristics of the logical volume. The correlation is accomplished by associating the first logical volume with a logical volume type based on predefined characteristics, assigning a time bin for the type of the first logical volume based on the time of last access of the first logical volume therein and based on the type assigned to the first logical volume at the time the first logical volume was last accessed and updating a usage count in the time bin for the type. Scores for each logical volume in the cache are updated by determining the age and type of each logical volume, selecting appropriate time buckets for the logical volume, calculating a usage score for the time buckets, computing time-weighted usage scores for the time buckets and identifying a final score for the logical volume. The logical volume with the lowest score is the next volume to be discarded from the cache.
摘要翻译：公开了一种用于改进虚拟磁带服务器的缓存的方法和装置。该方法和设备通过假设增加缓存命中来提高缓存，但是当这些假设证明不正确时，不会导致虚拟磁带服务器执行不足。该方法包括以下步骤：将逻辑卷使用与外部确定的文件特征相关联以导出用于缓存的逻辑卷的使用历史，维护共享相同预定义特性的文件的历史记录，以及根据逻辑卷的使用历史和外部确定的文件特性。通过基于预定特性将第一逻辑卷与逻辑卷类型相关联来实现相关性，基于其中的第一逻辑卷的最后访问的时间，基于类型为第一逻辑卷的类型分配时间段在上次访问第一个逻辑卷时分配给第一个逻辑卷，并更新该类型的时间段中的使用次数。通过确定每个逻辑卷的年龄和类型，为逻辑卷选择适当的时间段，计算时间段的使用分数，计算时间段的时间加权使用分数，并更新识别逻辑卷的最终得分。具有最低分数的逻辑卷是要从缓存中丢弃的下一个卷。

摘要： In a data storage system, a cache is managed by a predictive cache management engine that evaluates cache contents and purges entries unlikely to receive sufficient future cache hits. The engine includes a single output back propagation neural network that is trained in response to various event triggers. Accesses to stored datasets are logged in a data access log; conversely, log entries are removed according to a predefined expiration criteria. In response to access of a cached dataset or expiration of its log entry, the cache management engine prepares training data. This is achieved by determining characteristics of the dataset at various past times between the time of the access/expiration and a time of last access, and providing these characteristics and the times of access as input to train the neural network. As another part of training, the cache management engine provides the neural network with output representing the expiration or access of the dataset. According to a predefined schedule, the cache management engine operates the trained neural network to generate scores for cached datasets, these scores ranking the datasets relative to each other. According to this or a different schedule, the cache management engine reviews the scores, identifies one or more datasets with the least scores, and purges the identified datasets from the cache.
