Patent number: 10425486Abstract: An aspect includes detecting a recurring intermittent error in a path of a network in a system that includes at least one data transmission port configured for connection to at least one shared data storage device via a plurality of paths of the network. It is determined by a path control module (PCM) in the network, whether a path recovery action has been initiated by a fiber channel protocol driver in the network. In response to determining that the path recovery action has not been initiated, the data transmission port is prevented from accessing the path for a specified time period by moving the path into a degraded sub-state, and subsequent to the specified time period the data transmission port is provided access to the path. In response to determining that the path recovery action has been initiated, the data transmission port is provided access to the path.Type: GrantFiled: February 16, 2017Date of Patent: September 24, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Gary S. Domrow, Lee N. Helgeson, Ian A. MacQuarrie, James A. O'Connor, Shawn T. Wright

Patent number: 10177968Abstract: An aspect includes detecting a recurring intermittent error in a path of a network in a system that includes at least one data transmission port configured for connection to at least one shared data storage device via a plurality of paths of the network. It is determined whether a cause of the recurring intermittent error is a previous path recovery action. In response to determining that the cause of the recurring intermittent error is not a previous path recovery action, the data transmission port is prevented from accessing the path for a specified time period by moving the path into a degraded sub-state, and subsequent to the specified time period the data transmission port is provided access to the path. In response to determining that the cause of the recurring intermittent error is a previous path recovery action, the data transmission port is provided access to the path.Type: GrantFiled: November 10, 2016Date of Patent: January 8, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Gary S.

Patent number: 9189320Abstract: Embodiments relate to a computer for transmitting data in a network. The computer includes at least one data transmission port configured to be connected to at least one storage device via a plurality of paths of a network. The computer further includes a processor configured to detect recurring intermittent errors in one or more paths of the plurality of paths and to disable access to the one or more paths based on detecting the recurring intermittent errors.Type: GrantFiled: August 15, 2012Date of Patent: November 17, 2015Assignee: International Business Machines CorporationInventors: Ian A. MacQuarrie, James A. O'Connor, Limei Shaw, Thomas Walter, Thomas V. Weaver, Shawn T. Wright
