摘要:
An automated data storage library accesses data storage media from storage shelves in response to commands from an external host. The library receives and activates a firmware update in a processor node and determines whether a library door has been opened and/or closed during the code activation. Only if a library door has been opened and/or closed will an inventory of the storage media be performed.
摘要:
A method to activate a code update in a data storage drive. The method provides a code update to the data storage drive while the data storage drive performs normal drive operations. The method then detects a host computer transparent event, and activates the code update during that host computer transparent event.

An automated data library system employs a plurality of cartridges, a slot physically configured to store the cartridges, and a library controller operable to build a slot inventory of the slot storing the plurality of cartridges. The building of the slot inventory includes the library controller generating slot inventory data including cartridge identification information of each cartridge behind a lead cartridge in the slot, and the library controller writing a slot inventory including the slot inventory data to a cartridge memory of the lead cartridge.

An apparatus, system, and method are disclosed for managing control path commands in an automated data storage library. The present invention teaches a data storage library with stored data and at least one controller. The present invention also teaches at least one command source that provides commands to the data storage library via at least one control path. The data storage library stores a last successful command for each control path in the data storage library, receives a new command from a control path, compares the new command with one or more of the last successful commands, and executes the new command if the new command is unique.
摘要:
A storage subsystem, method of automatically maintaining the subsystem hardware configuration up to date and program product therefor. The storage subsystem automatically initiates hardware discovery in response to a triggering event. Subsystem hardware information is collected during hardware discovery and checked against a current configuration to identify hardware changes. Whenever hardware changes are identified, the subsystem configures the hardware and calibrates newly configured hardware. So, hardware changes may be automatically discovered, configured and calibrated free from operator intervention.

Disclosed are a system, a method, and article of manufacture to provide for managing data storage media to provide secure storage of the data storage media in an automated data storage library. A logical library partition vault is created in the automated data storage library that is not accessible by any host computer. Data storage media in the logical library partition vault may only be accessed by an operator using a secure means. The logical library partition vault may comprise various components of the automated data storage library by assigning storage shelves, service bays, data storage media, data storage drives or other library components to the logical library partition vault.
摘要:
An automated data storage library with storage shelves, data storage drive(s), a bus bar; and a robot accessor with a drive system for moving the robot accessor, an accessor communication interface, a bus bar relay configured to engage and disengage the bus bar; and a robot control configured to operate the drive system to move the robot accessor, to operate a picker, and to operate the bus bar relay to engage the bus bar when the robot accessor is stationary, to provide communication capability with a library communication interface via the bus bar relay and the bus bar when the bus bar relay engages the bus bar. Additionally, a second communication system may be provided between the robot accessor and the automated data storage library, which is operable at least when the robot accessor is moving.
摘要:
An automated data storage library accesses data stored on storage media contained in cartridges in response to commands from an external host. The cartridges include cartridge memory and a component in the library includes a cartridge memory interface for reading data from and/or writing data to the cartridge memory. When a cartridge is to be stored in the library, the library modifies the contents of the cartridge memory such that the data stored on the cartridge becomes inaccessible, thereby preventing access to the data outside of the library. To perform an authorized access, the library restores the contents of the cartridge memory or provides a correction or correction algorithm to allow access to the data without removing the access protection of the storage media. The cartridge memory may also or alternatively include an identifier which permits access to the data only by the identified physical and/or logical library(s).
摘要:
An automated data storage library provides for reducing inventory after media access. Media is moved, inserted, or removed without opening the access door normally associated with accessed media. A media status of a data storage drive within the automated data storage library is checked. An unexpected condition is detected at the data storage drive. An inventory of at least part of the library is performed for the unexpected condition. Alternately, a move operation is initiated for a data storage media wherein an unexpected condition is detected at the source and/or target location of the move operation. An inventory of at least part of the library is performed for the unexpected condition. In either embodiment, the unexpected condition includes a state of the automated data storage library which is inconsistent with a library database, such as a presence or absence of a data storage media in the location, or a data storage media in the location having an identifier which is inconsistent with the library database. The automated data storage library is brought back on-line after performing the inventory.

A key server provides keys for encryption and/or decryption for data storage drives. A first communication link provides at least data communication with respect to the data storage drive; a second communication link, separate from the first communication link, provides communication between the data storage drive and the key server; and the key server provides the encryption and/or decryption keys over the second communication link.
