| 20090063713 | System for Generating a Data Logout in a Computing Environment - A method and system are disclosed for generating a data logout in a computing environment having a processor and an input/output subsystem for receiving data from and sending data to the processor. The method comprises the steps of the input/output subsystem maintaining a defined set of data; at defined time, the processor issuing a data logout command; and sending said data logout command to the input/output subsystem. In response to receiving said data logout command, the input/output subsystem sends said defined set of data to a specified location. In a preferred implementation, the input/output subsystem includes a channel subsystem and a plurality of input/output devices, and the data logout command is sent to one of the input/output devices. Also, in the preferred embodiment, the channel subsystem includes a channel control unit function and the data logout command is sent to the channel control unit function. | 03-05-2009 |

| 20110320640 | DISCOVERY AND CONFIGURATION OF DEVICE CONFIGURATIONS - A computer program product for processing communications between a host processor and a plurality of devices includes a tangible storage medium for performing a method comprising: receiving, by the host processor, physical configuration information including identification of a location of each physical endpoint connected to the host processor and a plurality of communication paths associated with each physical endpoint; sending at least one message to each physical endpoint on each of the plurality of communication paths, the at least one message requesting identification of a logical entity at the endpoint, and receiving logical configuration information identifying the logical entity; and generating a data collection accessible by the host processor, the data collection including the physical configuration information and the logical configuration information for each logical entity, and identification of a location of each physical endpoint connected to the host processor and a plurality of communication paths to each logical entity. | 12-29-2011 |
| 20120110155 | MANAGEMENT OF A DATA NETWORK OF A COMPUTING ENVIRONMENT - An integrated hybrid system is provided. The hybrid system includes compute components of different types and architectures that are integrated and managed by a single point of control to provide federation and the presentation of the compute components as a single logical computing platform. | 05-03-2012 |
| 20120215946 | DISCOVERY AND CONFIGURATION OF DEVICE CONFIGURATIONS - A computer program product is provided for performing a method comprising: receiving, by the host processor, physical configuration information including identification of a location of each physical endpoint connected to the host processor and a plurality of communication paths associated with each physical endpoint; sending at least one message to each physical endpoint on each of the plurality of communication paths in response to receiving the physical configuration information, the at least one message requesting identification of a logical entity at the endpoint, and receiving logical configuration information identifying the logical entity; and generating a data collection accessible by the host processor, the data collection including the physical configuration information and the logical configuration information for each logical entity, and identification of a location of each physical endpoint connected to the host processor and a plurality of communication paths to each logical entity. | 08-23-2012 |
| 20120317567 | VIRTUAL NETWORK CONFIGURATION AND MANAGEMENT - A Hardware Management Console (HMC) configures virtual networks. The HMC extends Internal Queued Direct I/O to an intra-ensemble data network (IEDN) within a cluster of virtual servers to define a single channel path identifier, and to define a channel parameter. The HMC defines at least one virtual network. The HMC defines a bridge port within each CPC that supports at least one of the virtual servers. The HMC defines a network interface for each virtual server within each cluster. The HMC grants access to a corresponding virtual network for each virtual server. | 12-13-2012 |
