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 method to export and then import a logical volume with assigned storage attributes, from a first information storage medium to a second information storage medium. The method maintains a logical volume in a first information storage medium. The method assigns one or more first storage attributes to that logical volume. The method further includes forming an import list logical volume. The method further includes defining a plurality second storage attributes. The method further includes importing the logical volume, and the assigned first storage attributes, into a second information storage medium. The method then determines if the import list logical volume specifies use of one or more second storage attributes. If the import list logical volume specifies use of one or more second storage attributes, then the method assigns to the logical volume those one or more second storage attributes.

摘要： A method to write information to one or more information storage media disposed in a data storage and retrieval system comprising host adapters capable of data compression and information storage devices capable of data compression. The method establishes a storage medium usage threshold and determines the actual storage media usage level for the data storage and retrieval system. The method then determines if the actual storage media usage level is greater than the storage medium usage threshold. If the actual storage media usage level is greater than said storage medium usage threshold, then the method enables use of information storage device data compression. Alternatively, if the actual storage media usage level is not greater than said storage medium usage threshold, then the method disables use of information storage device data compression.

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 to write information to two virtual tape servers. The method writes a file to a virtual host device disposed in a first virtual tape server, where the virtual host device comprises an adjustable bandwidth. The method queues a job to copy the file to a second virtual tape server, determines the age of the copy job, and copies that file to the second virtual tape server. The method sets an age threshold, and determines if the copy job age is greater than that age threshold. If the copy job age is greater than the age threshold, then the method decreases the adjustable bandwidth, if not, the method restores the adjustable bandwidth.

摘要： A method to write information to two geographically separated virtual tape servers, where the method provides a file to a virtual tape controller, writes that file to a first virtual tape server, and queues a copy job for the file in the virtual tape controller. Subsequently, the method provides the file to a second virtual tape server. The method sets a throughput threshold, determines the actual VTC throughput, and determines if the actual VTC throughput exceeds the throughput threshold. The method sets an age threshold and determines if the copy job age is greater than that age threshold. If the actual VTC throughput is greater than the throughput threshold and the copy job age is greater than the age threshold, then the method decreases the first adjustable host bandwidth and/or the second adjustable host bandwidth, otherwise the method restores the bandwidth to a nominal value.

摘要： In one embodiment, a method for accessing host data records stored in a VTS system includes receiving a mount request to access at least one host data record, determining a SLBID corresponding to the requested host data records, determining a PBID that corresponds to the SLBID, accessing a physical block on a sequential access storage medium corresponding to the PBID, and outputting at least the physical block corresponding to the PBID without outputting an entire logical volume that the physical block is stored to. According to another embodiment, a VTS system includes random access storage, sequential access storage, support for at least one virtual volume, a storage manager having logic for determining a PBID that corresponds to a SLBID, and logic for copying a portion of a logical volume from the sequential access storage to the random access storage without copying the entire logical volume.

摘要： A method for offloading volume space reclamation operations to virtual tape systems is disclosed herein. In certain embodiments, such a method includes writing instruction information to a virtual tape system for use in performing a reclamation operation on a source virtual tape volume. The instruction information identifies the source virtual tape volume as well as valid objects in the source virtual tape volume. The virtual tape system then transforms the source virtual tape volume by retaining valid objects in the source virtual tape volume, removing invalid objects in the source virtual tape volume, and updating metadata associated with the source virtual tape volume to reflect changes made thereto. This generates an updated source virtual tape volume of reduced size. A corresponding computer program product and system are also disclosed and claimed herein.
