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 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 maintain information by assigning one or more storage attributes to each of a plurality of logical volumes. The method writes a first portion of a dataset to a first logical volume. The method assigns one or more storage attributes to that first logical volume. When the logical end of volume for the first logical volume is approaching, Applicants' method mounts a second logical volume, and continues writing the dataset to that second logical volume. The method assigns the same one or more storage attributes to the second logical volume.

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.
