摘要:
A library is reset as needed in a manner non-disruptive to a host system providing a host command to a drive interfacing with the host system on behalf of the library during a reset of the library. To this end, the drive confirms a receipt of a host command to the host system on behalf of the library in response to the drive receiving the host command from the host system, and the library commands the drive to transmit the host command to the library subsequent to a reset of the library based on the drive receiving the host command from the host system during the reset of the library.

An apparatus, system, and method are disclosed for backing up vital product data for a data processing device. A communication module establishes a communications channel with a maintenance module of a service center. The service center remotely supports the data processing device. A backup module copies vital product data to the maintenance module and the maintenance module maintains the vital product data copy. In one embodiment, a restore module receives a command to restore the vital product data copy. The communication module establishes the communications channel between the restore module and the maintenance module and the maintenance module copies the vital product data copy to the restore module.

An apparatus, system, and method are disclosed for managing physical addresses of data storage media within a data storage library. The library maintains a data table of storage slots and the media stored in those slots. The data table may contain addresses for storage slots that are not physically present or accessible within the library. Hardware such as storage slots may be added or removed without causing an inconsistency within the data table of assigned addresses. Addresses may be recorded as the particular frame, column, and row that describe the location of a particular storage slot. Each data storage media is associated with a particular host. The data table of the library maintains a record of data storage media and the host affinity the media corresponds to.

Methods, system and computer program product are provided for managing and tracking on-demand removable, serialized data resources, such as storage frames, storage drives and media, in an automated data storage library. Storage frames, data storage drives and media are tracked by the automated data storage library to prevent use or misappropriation until authorized. Alternatively, or additionally, the data storage drives may be prevented from being used until instructed to do so. In addition, the media may be prevented from being used until modification is made to the medium or cartridge memory of the data storage media.

A method, system and a computer program product to increase the availability of an automated data storage library for accessing and storing data storage media are provided. Work requests received by an accessor controller of the library from a host computer are also received and stored by a work request tracking controller. The accessor controller converts the work request into commands necessary to direct an accessor to fulfill the work request, and then sends such commands to an accessor. Upon detection by the work request tracking controller that the so-directed accessor failed to conduct the command issued by the accessor controller, the work request tracking controller reconstructs the work request and sends it to an accessor controller. The provision of a work request tracking controller is a failover mechanism in the event an accessor controller fails to successfully direct an accessor to conduct commands in furtherance of a work request and/or has, for whatever reason, lost the work requests in its queue.

A removable media storage network environment employs a media management system for managing a removable media system on behalf of client applications, and a media management agent to enhance the management of the removable media system by the media management system. The media management agent operates to determine an operational state of the removable media system, and to enhance an availability and a performance of the removable media system as managed by a media management system, wherein one or more one error recovery techniques are conditionally initiated based on the determined operational state of the removable media system and wherein the media management system is conditionally reconfigured based on the determined operational state of the removable media system.
摘要:
A method for displaying physical address of data storage media residing within an automated data storage library. A drive, including a drive processor and a drive display, recognizes a load display request received from a host computer/application that includes an identification of a data storage medium. The drive generates a request for the physical address of the data storage medium corresponding to the identification and transmits the request to a library controller. The library controller looks up the corresponding physical address and transmits it back to the drive, where it is displayed on the drive display.

Disclosed is a deep slot magazine storage library including a library housing defining a magazine cavity and including an active robotic end and a magazine loading and unloading end. Also included is a plurality of deep slot magazines storable by height and width within the magazine cavity, wherein each of the plurality of deep slot magazines is individually removable from the magazine cavity and wherein each of the plurality of deep slot magazines defines a cartridge cavity. Further included is a plurality of vertical magazine supports disposed within the magazine cavity, wherein the plurality of vertical magazine supports allow individual support of each of the plurality of deep slot magazines. Still further included is a plurality of cartridges removably storable by height, width, and depth within a plurality of cartridge slots defined by at least one cartridge support guide disposed within the cartridge cavity.
