International Classification:

G06F 17/00

US Classification:

702182, 702 85, 702105, 700214

Abstract:

An apparatus, system, and method are disclosed for performing an abbreviated calibration of an automated data storage library. An abbreviated calibration apparatus includes a calibration module, a tracking module, and a system availability module. The calibration module calibrates one or more accessors within the library. Calibration refers to the physical relationship between an accessor and a data storage location, such as a shelf, drive, or I/O station. The calibration module may comprise a run-time calibration module, a successive calibration module, or a cooperative calibration module. The tracking module tracks the calibration progress of the accessors. The system availability module notifies a host when the library is available. The library is made available prior to calibration completion of all of the accessors and, in some embodiments, prior to calibration completion of any of the accessors.

US Classification:

711154, 711200, 711209, 713200

Abstract:

A device, method, and system for switching library managers of a data library while maintaining data library storage devices online. A library manager accepts and executes data transaction commands for access to data residing on the storage devices of the data library. A transition manager module receives a directive to transition library management functions from a first library manager to a second library manager. The transition manager module stops the first library manager from accepting new data transaction commands while maintaining the storage devices online. The first library manager may execute previously accepted data transaction commands. The transition manager module suspends the library management functions of the first library manager and activates the library management functions of the second library manager. The storage devices of the data library may complete data transaction commands throughout the library manager transition.

Inventors:

Dennis Martinez - Tucson AZ, US
Tom Pringle - Tucson AZ, US

International Classification:

G06F007/00

US Classification:

700214000

Abstract:

A high input/output (I/O) capacity, multi-frame storage subsystem, method of inserting/ejecting storage media in the storage subsystem and program product therefor. The storage media, e.g., magnetic tape in a physical volume, is placed into storage cells in a service bay before being inserted into the subsystem library or after being ejected from a data library in the subsystem. Whenever the service bay door is opened, the accessor is prevented from entering the service bay and tape cartridges may be inserted in the service bay storage cells or removed from the storage bay storage cells without pausing the subsystem.
