    摘要: A storage manager application implemented in a first computational device maintains a virtual logical volume having a plurality of segments created by the storage manager application, wherein space is reserved at the end of a physical volume corresponding to the virtual logical volume, and wherein the physical volume comprises a linear storage medium. A request is received to write data, at the first computational device, from a second computational device. The data is written to the reserved space, wherein the writing of the data causes new segments to be created in the reserved space.

    摘要: The provision of verification for data storage cartridges having data storage tape media employs determining the volume identity of a data storage cartridge; and providing an internal label at each block of data to be written to the data storage tape media of the data storage cartridge, the internal label at least comprising the volume identity. Verification of a label comprises reading an external label of the cartridge, the external label at least comprising a volume identity of the cartridge; determining whether the tape media comprises valid data arranged in blocks; positioning the tape media at one of the data blocks and attempting to read an internal label from the data block; and if so, determining whether the volume identity of the external label matches the volume identity of the internal label, and, if so, determining that the matching volume identity is the volume identity of the cartridge.

    摘要: Upgrades are made to the available capacity of cache disk storage without adding drawer(s) or blade(s) when the upgrade is requested. A cache control is configured to respond to a requested capacity upgrade, establishing a capacity restriction applicable to a filesystem providing active perceived available capacity spanning the disk drive subunits, such as drawers, blades or disk drives. The active perceived available data storage capacity and unused capacity of the filesystem are spread across the disk drive subunits. The capacity restriction is related to the requested upgrade adjustment, and the capacity restriction controls rates of data transfer with respect to the filesystem. The capacity restriction may comprise a freespace threshold for throttling of a fill rate of resident data pending premigration from the cache disk storage filesystem, and a premigration threshold for increasing drain rate of premigration data from the cache disk storage filesystem.

    摘要: With detection of a selected error event involving a data storage drive and data storage media, a subsystem attempts to move the media to another drive, and conduct a similar operation. The subsystem separately tracks successive error events of individual drives and individual media, wherein a complete successful operation breaks the chain of the successive error events; and upon the number of successive error events reaching a threshold, fails the data storage drive or the data storage media. Error events are categorized into: 1) error events before or during a mount of a media into a drive, and 2) error events after a successful mount of a media into a drive; and conducts the tracking, comparing and falling steps separately for each of the categories for the drives and the media.
