Publication number: 20150121390Abstract: In some embodiments of this disclosure, a computer-implemented method includes requesting, by a first thread on a computer system, conditional exclusive access to a first resource for updating the first resource to perform a first task. An indication is received that the requested exclusive access to the first resource is currently unavailable. Unconditional shared access to the first resource is requested after receiving the indication that the requested exclusive access is unavailable. The shared access to the first resource is received. The first resource is used, by a computer processor, through the shared access to perform the first task in lieu of the requested exclusive access.Type: ApplicationFiled: October 24, 2013Publication date: April 30, 2015Applicant: International Business Machines CorporationInventors: Richard A. Bibolet, Scott B. Compton, William J. Rooney

Patent number: 9003142Abstract: A mechanism is provided for adding point-in-time copy relationships to a data processing system. A request is received to establish a first point-in-time copy relationship. Responsive to determining that a first target of the first point-in-time copy relationship is target write inhibited, that a source of the first point-in-time copy relationship is a source of a first continuous synchronous copy relationship, that a target of the first continuous synchronous copy relationship is part of a second point-in-time copy relationship, and that the source of the first point-in-time copy relationship is part of a volume swap configuration, a volume swap relationship is added between the first point-in-time target volume and the second point-in-time target volume to the volume swap configuration.Type: GrantFiled: July 30, 2013Date of Patent: April 7, 2015Assignee: International Business Machines CorporationInventors: David R. Blea, Gregory E. McBride, William J. Rooney

Publication number: 20150088821Abstract: In one embodiment of the present description, data is migrated to a replacement source storage unit of a storage subsystem while being mirrored from the original source storage unit of a storage subsystem to an original target storage unit of a storage subsystem, and the original source storage unit and the replacement storage unit are swapped in a multi-storage volume swap to write updates to the replacement source storage unit instead of the original source storage unit, in input/output operations issued by at least one host. Further, data stored in the replacement source storage unit, is mirrored from the replacement source storage unit to the original target unit. Other aspects are described.Type: ApplicationFiled: September 23, 2013Publication date: March 26, 2015Inventors: Amy N. Blea, David R. Blea, Gregory E. McBride, William J. Rooney, John J. Wolfgang

Patent number: 8914671Abstract: A method includes monitoring a plurality of HyperSwap sessions between one or more storage systems located at a first location and one or more storage systems located at a second location, wherein at least one of the one or more storage systems located at the first location and at the second location are designated as a primary storage system. The method includes detecting an error event and freezing communications between the storage systems located at the first location and the second location in response to the error event. The method also includes designating either the first location or the second location as a preferred location and modifying the designation of all of storage systems at the preferred location to be primary storage systems in response to the error event.Type: GrantFiled: March 4, 2013Date of Patent: December 16, 2014Assignee: International Business Machines CorporationInventors: William J. Rooney, Peter G. Sutton

Patent number: 8909383Abstract: A method to reduce large temperature over/undershoot in a computer system. Using workload data, the method proactively modifies controls of mechanical cooling system to anticipate power and take appropriate actions to maintain temperature. Workload control modifies workload and scheduling to reduce power transients and subsequent temperature deviations. In addition, workload control allows more even distribution of temp across chips, allowing for even wear and reduction of small/ripple/noise temp oscillations. A system and program product for carrying out the method are also provided.Type: GrantFiled: December 22, 2011Date of Patent: December 9, 2014Assignee: International Business Machines CorporationInventors: Scott J. Hadderman, Daniel J. Kearney, Wei Huang, K. Paul Muller, William J. Rooney, Guillermo J. Silva, Malcolm S. Ware, Emmanuel Yashchin, Peter B. Yocom

Patent number: 8898413Abstract: A method includes making in a real storage, a copy of a first page content stored in a first page data structure by creating a second page content in a second data structure, the second page content pointing to actual data pointed to by the first page content, storing the second page content in the second data structure, marking the first page content in the first page data structure with a page protection bit, wherein the page protection bit prevents a modification of the virtual page, in response to an attempt to modify the virtual page, copying the virtual page in the event the first page content in the first page data structure is marked with the page protection bit, storing the copied virtual page in a second virtual storage, and altering the second page content in the second data structure to point to the stored virtual page.Type: GrantFiled: June 21, 2011Date of Patent: November 25, 2014Assignee: International Business Machines CorporationInventors: Mark S. Farrell, William J. Rooney, Elpida Tzortzatos
