    摘要: A method to assign one or more new storage construct names to one or more logical volumes using an operator input station capable of communicating with a virtual tape system, where that virtual tape system includes a plurality of existing logical volumes and a database which includes a plurality of logical volume records. The method first defines one or more new storage construct names, associates one or more storage actions with each of those new storage construct names, and saves the new storage construct names and the associated storage actions in the database. The method then enters, using the operator input station, a range of logical volumes, selects one or more new storage construct names, associates those new storage construct name to the range of logical volumes. The method then determines if the range of logical volumes comprises existing or new logical volumes. If the range of logical volumes comprises existing logical volumes, then the method modifies the logical volume records for that range of logical volumes to include the new storage construct names. If the range of logical volumes comprises new logical volumes, then the method creates new database records for that range of logical volumes comprising the new storage construct name.

    摘要: A method to import a logical volume and first storage attributes assigned to that logical volume into a second virtual tape system from a first virtual tape system. The method assigns one or more first storage attributes to that logical volume, assigns an identifier, and writes an export physical volume comprising the logical volume, the first storage attributes, and the identifier. The method then imports the logical volume, the logical volume identifier, and the first storage attributes, into the second virtual tape system, and associates one or more construct overridden flags with the logical volume if the second virtual tape system specifies use of one or more of 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: An apparatus, system, and method are disclosed for selecting a source cluster in a distributed storage configuration. A measurement module measures system factors for a plurality of clusters over a plurality of instances. The clusters are in communication over a network and each cluster comprises at least one tape volume cache. A smoothing module applies a smoothing function to the system factors, wherein recent instances have higher weights. A lifespan module calculates a mount-to-dismount lifespan for each cluster from the smoothed system factors. A selection module selects a source cluster for accessing an instance of a specified volume in response to the mount-to-dismount lifespans and a user policy.

    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.

    摘要: A system and method for processing data storage mediums (DSMs) that are not stored in an automated data storage library on medium drive devices that are part of the library. An input station used to add DSMs is enabled to serve as an input and output window for transient data storage mediums (TDSMs) so that DSMs are not dislodged from the storage bins. An operator may automatically place the library's robotic picker in a "TDSM mount mode" when an attached host processor requests one or more data volumes stored on one or more TDSMs. A library-manager controller can be automatically configured to interact with the library's robotic pickers to transfer a TDSM from the input/output station to a device, such as a tape drive within the library. The library manager controller is automatically configured to ignore the machine readable external label of a TDSM so that it is not necessary to place such a label on a TDSM. The controller can notify the operator when processing of the data volume is complete and return the TDSM to the input/output station for ejection from the library. By employing this system and method existing hardware of an automated library system is employed to achieve processing of TDSMs without the need for a drive device outside of the library to process the TDSM data volumes.
