  • Method, apparatus and program storage device for providing asynchronous status messaging in a data storage system
    Patent number: 7676616
    Abstract: A method, apparatus and program storage device for providing asynchronous status messaging in a data storage system Asynchronous events are returned from a target to an initiator in response to a Read Message from the initiator. The return status message may or may not be associated with a previously given command or Logical Unit (LUN).
    Type: Grant
    Filed: September 7, 2007
    Date of Patent: March 9, 2010
    Assignee: International Business Machines Corporation
    Inventors: Brent C. Beardsley, Minh-Ngoc Le Huynh, William F. Micka, Satish Chandra Penmetsa, Richard A. Schaeffer, Kaukab Uddin

  • Concurrent PPRC/FCP and host access to secondary PPRC/FCP device through independent error management
    Patent number: 7197663
    Abstract: A method of error management in a data storage system having a target device, with the target device receiving commands from a first initiator and the target device concurrently receiving commands from a second initiator. The target device is typically a storage device operating as a PPRC secondary. A first initiator is a device which communicates with the target device through small computer systems interface (SCSI) protocol. The first initiator is typically a host computer or server. The second initiator communicates with the target device through peer-to-peer remote copy PPRC initiator mode commands. The second initiator is typically a separate storage device in a peer-to-peer remote copy (PPRC) relationship with the target device. The method consists of managing errors associated with a command sent to the target device from the first initiator independently from the management of errors associated with a command sent to the target device from the second initiator.
