Abstract: A computer program product for eliminating access to data within a writable storage media cartridge includes a computer readable medium having program instructions embodied therewith. The program instructions are executable by a processing circuit to cause the processing circuit to determine whether a first portion of data on the writable storage media cartridge is encrypted, and determine whether key shredding is enabled. In response to determining that key shredding is not enabled, the processing circuit causes performance of a long erase on at least the encrypted first portion of data, and causes shredding of an encryption key related to said encrypted first portion of data.

Abstract: A virtual tape server for implementing a method for exporting one or more logical volumes contained in a source physical volume pool. The method involves an activation of an export clone pool to clone an identity of the source physical volume pool into the export clone pool based on the logical volumes, an exportation of the export clone pool including the logical volumes subsequent to the activation of the export clone pool, and a deactivation of the export clone pool to purge the identity of the source physical volume pool from the export clone pool subsequent to the exportation of the export clone pool.

Abstract: 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.

Abstract: 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.
