20100070663 | APPARATUS AND METHOD TO PRESERVE ONE OR MORE LOGICAL COMMUNICATION PATHS IN A DATA PROCESSING SYSTEM - A method to preserve a logical communication path in a data processing system, that includes a host computer, a storage controller that comprises a first logical control unit (“LCU”), and a logical communication path that is in communication with the host computer and the first LCU, comprising deleting the first LCU and setting a first status for same. The method then configures a second LCU, and establishes a second status for same, wherein the second LCU includes all or a portion of the first LCU, but is not the same as the first LCU. The deleting, setting, configuring, and establishing are performed while maintaining the logical communication path, which is in communication with the second LCU. | 03-18-2010 |

20090187891 | VERIFICATION OF INPUT/OUTPUT HARDWARE CONFIGURATION - A method for verifying an input/output (I/O) hardware configuration is provided. A verification command is processed. The verification command includes a software device address range associated with a logical control unit (LCU) of the I/O hardware. The LCU utilizes a first logical path. The software device address range utilizing the first logical path is compared with an existing software device address range utilizing at least one additional logical path. The verification command is accepted if the software device address range and the existing software device address range match. | 07-23-2009 |
20100023801 | Method to recover from ungrouped logical path failures - A system and method for recovering from a single logical path failure. More specifically, although a host has not grouped its logical paths, the host knows which logical paths it has available. When a host detects a logical path failure, the host enters a path discovery mode of operation. If the host continues to detect a logical path failure while operating in the logical path discovery mode of operation, the host removes the logical path from a logical path mask, and the host does not use the removed logical path again. In the case of ungrouped logical paths, the host aborts its process because it does not have more paths available to continue its process. Additionally, in certain embodiments, a pseudo path group for ungrouped logical paths is created. | 01-28-2010 |
20100023802 | Method to recover from logical path failures - A system and method for recovering from logical path failures is set forth. More specifically, when a host detects a logical path failure, the host enters a path discovery mode of operation. If the host continues to detect a logical path failure while operating in the logical path discovery mode of operation, the host removes the logical path from a logical path mask, and the host does not use the removed logical path again. Additionally, the system and method facilitates recovery of the failed logical paths by using a plurality of logical path masks. A first mask is referred to as an intermediate failure logical path mask and a second mask is referred to as a permanent failure logical path mask. | 01-28-2010 |
20130024586 | VERIFICATION OF HARDWARE CONFIGURATION - A method for verifying an input/output (I/O) hardware configuration is provided. Data from an input/output data set (IOCDS) is extracted for building a verification command. The IOCDS contains hardware requirements that define at least software devices associated with a logical control unit (LCU). The verification command is processed. The verification command includes a software device address range associated with a logical control unit (LCU) of the I/O hardware. The LCU utilizes a first logical path. The software device address range utilizing the first logical path is compared with an existing software device address range utilizing at least one additional logical path. The verification command is accepted if the software device address range and the existing software device address range match. | 01-24-2013 |

20150233744 | Flowmeter - A flow meter for measuring the flow of fluid through a pipe. The flow meter has an elongate member attached to an interior surface of the pipe. The elongate member has a leading end, a trailing end, a longitudinal axis, a first side, and a second side. The first side extends from the leading end to the trailing end and defines a cylindrical cross-sectional shape with a radius of curvature corresponding to the radius of curvature of the pipe and extending along an arc of less than 180 degrees. The second side extends from the leading end to the trailing end and is exposed to the interior of the pipe. The second side forms a constriction in a cross-sectional area of the pipe. Pressure sensors determine a pressure differential caused by the elongate member which is used to determine the volume of fluid flowing through the pipe. | 08-20-2015 |

20160045495 | ARIPIPRAZOLE PRODRUG COMPOSITIONS - Described is a composition comprising (a) a population of particles of an aripiprazole prodrug having a volume based particle size (Dv50) of less than 1000 nm and (b) at least one surface stabilizer comprising an adsorbed component which is adsorbed on the surface of the aripiprazole prodrug particles and a free component available for solubilisation of the aripiprazole prodrug. The surface stabilizer to prodrug ratio provides the optimal quantity of free surface stabilizer for the purposes of producing a lead-in formulation. Also described are methods of treatment using the aforementioned composition. | 02-18-2016 |
