Appl. No.:

10/465369

Inventors:

Timothy Alan Griffin - Tuscon AZ, US
Roger Gregory Hathorn - Tucson AZ, US
Bret Wayne Holley - Tuscon AZ, US
Lawrence Carter Blount - Tucson AZ, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G01R 31/28

US Classification:

714741, 714743

Abstract:

Provided are a method, system, and program for simulating I/O requests to test a system coupled to an adaptor having a port used for transmitting and receiving I/O requests to the system. A user test command is received indicating an I/O test object. The adaptor processes the I/O test object indicated in the user test command to generate a sequence of simulated I/O requests and transmits the generated simulated I/O requests to the system.

International Classification:

G06F 11/00

US Classification:

711162, 711161

Abstract:

A target data storage system comprises a peer-to-peer communication link interface for linking the target to a source data storage system, and data storage for storing point in time copy data received from the source via the peer-to-peer communication link interface. Information is established at the target relating logical identification of the point in time copy data to point in time copy data stored at the target and to point in time copy data stored at the source, such that the information references the data storage system having requested point in time copy data. A controller of the target accesses requested point in time copy data at the target if the table indicates that the requested point in time copy data is available at the target; else obtains the requested point in time copy data from the source via the peer-to-peer communication link interface.

US Classification:

395821

Abstract:

A system and method for processing data storage mediums (DSMs) that are not stored in an automated data storage library on medium drive devices that are part of the library. An input station used to add DSMs is enabled to serve as an input and output window for transient data storage mediums (TDSMs) so that DSMs are not dislodged from the storage bins. An operator may automatically place the library's robotic picker in a "TDSM mount mode" when an attached host processor requests one or more data volumes stored on one or more TDSMs. A library-manager controller can be automatically configured to interact with the library's robotic pickers to transfer a TDSM from the input/output station to a device, such as a tape drive within the library. The library manager controller is automatically configured to ignore the machine readable external label of a TDSM so that it is not necessary to place such a label on a TDSM. The controller can notify the operator when processing of the data volume is complete and return the TDSM to the input/output station for ejection from the library.
