摘要:
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.
摘要:
Disclosed is a method, system, and program for using storage slots efficiently. A storage element count is assigned to each one of multiple logical libraries, and the sum of the storage element count for each one of the multiple logical libraries exceeds the total number of storage slots in the library.

Disclosed is a method, system, and program for using storage slots efficiently. A move command is received to move a portable data storage medium from a source address to a destination address. An empty storage slot that has no association with the destination address is located. The portable data storage medium is moved from the source address to the located empty storage slot. An association is stored between the located empty storage slot and the destination address.
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.

Provided are a system and program for allowing communication among nodes in a system. A request is received in a source node from a source object executing in the source node to send a message to a destination object executing in a destination node. Each node includes a processor capable of multitasking multiple program objects and a communication interface to transmit and receive data with the other nodes. A determination is made in the source node as to whether the destination node and source node are a same node. The message is sent in the source node to the destination object within the source node if the destination node is the source node. If the destination node is not the source node, then the source node transmits the message to the destination node through the communication interface. The destination node sends the message to the destination object within the destination node.

摘要:
A dual purpose media drive exchanges data with removable media items. The drive includes at least one port to receive various control signals, including (1) data exchange commands directing the drive to read and/or write data to a media item mounted by the drive, and (2) robotic device management commands. The drive includes a processor that responds to incoming data exchange commands by reading and/or writing to the loaded media item. The processor responds to at least some robotic device management signals by forwarding them to a robotic media transport device. The processor withholds the data exchange commands from the robotic device, since they are only pertinent to operations of the drive itself. The robotic device may be configured to restrict host access to library components according to predefined logical partitions.

An apparatus and method are disclosed for managing component identifiers in a data storage system. The apparatus includes a recognition module, a receiving module, a comparison module, and an update module. The recognition module recognizes newly installed components. The receiving module receives a component identifier stored on the newly installed component. The comparison module compares the identifier of the newly installed component with one or more component identifiers stored in a computer system memory. The update module updates the one or more component identifiers stored in the system memory based upon the identifier of the newly installed component.

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.
