摘要： A method and apparatus for maintaining information in one or more virtual volume aggregates comprising a plurality of virtual volumes. The method maintains a plurality of virtual volumes in a first information storage medium, and forms one or more virtual volume aggregates, where each of the of virtual volumes is assigned to one of the virtual volume aggregates. The method further provides a plurality of second information storage media. The method then identifies the least recently used virtual volume, and writes the virtual volume aggregate comprising that least recently used virtual volume to one or more second information storage media. Thereafter, the method determines if space is required on said first information storage medium. If space is required on said first information storage medium, the method selects the virtual volume aggregate comprising the least recently used virtual volume and removes from said first information storage medium each virtual volume in that selected virtual volume aggregate that has been written to one or more second information storage media.

摘要： A method to form one or more premigration aggregates comprising a plurality of least recently accessed virtual volumes disposed in an information storage medium. The method determines the number (R) of virtual volumes to remove from the information storage medium, selects the (R) least recently accessed virtual volumes, forms one or more premigration aggregates comprising those least recently accessed virtual volumes, and assigns each of the (R) selected virtual volumes to one of those premigration aggregates. The method establishes a minimum transfer size and determines if any of the premigration aggregates are larger than that minimum transfer size. The method writes to one or more physical volumes each of the premigrate aggregates that are larger than the minimum transfer size. Thereafter, the method removes from the information storage medium each of the premigration aggregates written to physical volumes.

摘要： A method to assign a premigration pseudotime attribute and a stubbing pseudotime attribute to a logical volume. The method defines a plurality of host requests, and associates with each host request a pseudotime range. The method further maintains a logical volume in a first information storage medium at a first time, and determines if a user provides a host request for that logical volume. If a user provides a host request for that logical volume, then the method assigns to the logical volume a premigration pseudotime attribute, and a stubbing pseudotime attribute, comprising a time within the pseudotime range associated with the host request. If, on the other hand, a user does not provide a host request for the logical volume, then the method assigns to that logical volume the first time as said premigration pseudotime attribute, and said first time as said stubbing pseudotime attribute. The method saves the assigned premigration pseudotime attribute and the assigned stubbing pseudotime attribute for later use.

摘要： A system and method for guaranteeing overwrite of expired data in a media device, the data being organized according to logical units provided on media devices organized as physical volumes. The method comprises the steps of: maintaining information associated with a status of a physical volume, and updating a physical volume's status information based upon a combination of that volume's prior status and that volume's current status; specifying a time duration that expired logical unit data may remain on a physical volume; based upon the volume's updated status information, determining whether a selected volume has expired data longer than the specified time duration; and, overwriting contents of the volume having data that has expired longer than the specified time duration.

摘要： A media server (e.g., a virtual tape server) implements a method for a dynamic media format conversion of physical volumes stored within a media library (e.g., a tape library). The method involves a recall of volume data in a media format f as stored in one or more source physical volumes of a source media, and an automatic premigration of the recalled volume data in a media format f to one or more target physical volumes of a target media. The media format f is different in one or more aspects from the media format f.

摘要： A method and apparatus for handling multi-volume datasets in a tape storage system are disclosed. In response to a write request for a multi-volume dataset, the information of the multi-volume dataset are captured by intercepting and deciphering a set of volume mount commands. Otherwise, the information of the multi-volume dataset are captured by snooping header information from a previous volume listed in a header of the multi-volume dataset. A chain of logical volume names that belongs to the multi-volume dataset is then built. Finally, the chain of logical volume names is then stored in a chain database.

摘要： A method for providing continuous access to shared tape drives from two virtual tape server (VTS) nodes is disclosed. A group of tape drives are connected to two VTS nodes via a set of switches. Both VTS nodes can concurrently process requests to mount physical tape cartridges to separate tape drives. The selection of a tape drive to fulfill a volume mount request on a physical volume begins by locking down any access to a tape drive table having a composite view of all the tape drives shared between the two VTS nodes. An available tape drive is then selected to mount the physical volume, and an entry in the tape drive table is updated to claim ownership of the tape drive. A reservation command is sent to the tape drive to lock down any access to the tape drive, and the lock to the tape drive table is released. Having claimed ownership to the tape drive, the VTS node can now perform the volume mount request.

摘要： A mechanism is provided for reducing the backup time of data files from a memory. Data files are pre-staged by identifying the data files in the memory to be backed up to a backup storage system, sorting the data files by size thereby forming a set of small data files and a set of large data files, and copying the set of small data files to a cache while leaving the set of large data files in a disk subsystem. The set of small data files are then backed-up from the cache and the set of large data files are backed-up from the disk subsystem to a backup storage system. Thus, the time required to backup the set of small data files from the cache is performed at a faster rate as compared to backing up the set of large data files from the disk subsystem.
摘要翻译： 提供了一种减少数据文件从存储器的备份时间的机制。 数据文件通过识别要备份到备份存储系统的内存中的数据文件进行预分类，按尺寸对数据文件进行排序，从而形成一组小数据文件和一组大数据文件，并复制集 将小数据文件导出到高速缓存，同时将一组大型数据文件留在磁盘子系统中。 然后从缓存中备份一组小型数据文件，并将大量数据文件集从磁盘子系统备份到备份存储系统。 因此，与从磁盘子系统备份一组大型数据文件相比，从缓存中备份一组小数据文件所需的时间以更快的速度执行。
