    摘要： A method, system, and computer program product for connection state recovery of a connection after fault in a networked channel-to-channel computer system are provided. The method includes identifying essential data in response to detecting a state change in a channel of the computer system, the essential data including connection state information used in performing a recovery operation. The method also includes separating the essential data from transient or incidental data, augmenting the essential data with validation data, and storing the augmented essential data in a memory location of a control unit in communication with the channel. In response to initiation of a recovery operation, the method includes retrieving the augmented essential data and validating contents of persistent data fields containing the essential data. The method further includes using the contents to restore the connection to an operational state when it is determined that the contents of the persistent data fields are valid.

    摘要： An article of manufacture, an apparatus, and a method for providing extended measurement word data from a control unit to a channel subsystem of an I/O processing system are disclosed. The article of manufacture includes at least one computer usable medium having computer readable program code logic. The computer readable program code logic performs a method including receiving a command message from the channel subsystem at the control unit, and initiating a timing calculation sequence of a plurality of time values in response to receiving the command message at the control unit. The computer readable program code logic also populates extended measurement word data at the control unit including the plurality of time values, and outputs the extended measurement word data from the control unit to the channel subsystem.

    摘要： A computer program product, apparatus, and method for handling early termination of an I/O operation at a channel subsystem in an I/O processing system are provided. The computer program product includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. The method includes receiving a request to terminate an I/O operation, and transmitting an abort command to a control unit in communication with the channel subsystem in response to receiving the request to terminate the I/O operation. The method also includes transmitting a purge path command to purge a path associated with the I/O operation, where the purge path command includes an error code identifying the request to terminate the I/O operation.
