摘要： The state of an input/output (I/O) operation is determined in an I/O processing system. A command is received from an I/O operating system at a channel subsystem for initiating the I/O operation, a time period is for completion of the I/O operation, and the command for initiating the I/O operation is sent from the channel subsystem to the control unit. Responsive to the time period nearing elapsing without the I/O operation completing, a cancel instruction is received from the I/O operating system at the channel subsystem. Responsive to a determination by the I/O operating system to interrogate the control unit, an instruction to interrogate the control unit is received with the cancel instruction from the I/O operating system.

摘要： An approach to detecting processor failure in a multi-processor environment is disclosed. The approach may include having each CPU in the system responsible for monitoring another CPU in the system. A CPUn reads a timestampn+1 created by CPUn+1 which CPUn is monitoring from a shared memory location. The CPUn reads its own timestampn and compares the two timestamps to calculate a delta value. If the delta value is above a threshold, the CPUn determines that CPUn+1 has failed and initiates error handling for the CPUs in the system. One CPU may be designated a master CPU, and be responsible for beginning the error handling process. In such embodiments, the CPUn may initiate error handling by notifying the master CPU that CPUn+1 has failed. If CPUn+1 is the master CPU, the CPUn may take additional steps to initiate error handling, and may broadcast a non-critical interrupt to all CPUs, triggering error handling.
摘要翻译：公开了一种在多处理器环境中检测处理器故障的方法。该方法可以包括使系统中的每个CPU负责监视系统中的另一个CPU。 CPUn读取CPUn + 1创建的时间戳+1，CPUn正在从共享内存位置进行监控。 CPUn读取自己的时间戳，并比较两个时间戳来计算增量值。如果增量值高于阈值，CPUn确定CPUn + 1失败，并启动系统中CPU的错误处理。一个CPU可能被指定为主CPU，并负责开始错误处理过程。在这种实施例中，CPUn可以通过通知主CPU CPUn + 1失败来启动错误处理。如果CPUn + 1是主CPU，CPUn可能会采取额外的步骤来启动错误处理，并可能会向所有CPU广播非关键中断，从而触发错误处理。

摘要： An article of manufacture, an apparatus, and a method for determining an extended measurement word at a channel subsystem of an I/O processing system using data from a control unit are provided. 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 sending a command message to the control unit, and receiving a transport response information unit message at the channel subsystem in response to sending the command message to the control unit.

摘要： A computer program product, apparatus, and method are provided for determining a state of an input/output (I/O) operation in an I/O processing system. A request from a channel subsystem is received at a control unit for performing the I/O operation. After a predetermined amount of time passes without the I/O operation completing, an interrogation request is received from the channel subsystem at the control unit for determining the state of the I/O operation. A response is sent from the control unit to the channel subsystem indicating the state of the I/O operation in response to the interrogation request. The response also includes information regarding a state of an I/O device executing the I/O operation and information indicating a state of the control unit controlling the I/O device executing the I/O operation.

摘要： A Fibre Channel over Ethernet (FCoE) device obtains knowledge of the configuration of an attached Ethernet fabric from data fields within a frame header during a fabric initialization or login (FLOGI) process. FCoE N_Ports obtain similar information during the port initialization or login (PLOGI) process. The FCoE device may provide network management services to attached FCoE devices. Embodiments include a management module or processor within an FCoE N_Port. The management module or processor receives a frame having a header and validates and extracts information associated with an Ethernet fabric from the FCoE N_Ports and in order to provide management services based on the information associated with the Ethernet fabric. The FCoE N_Port communicatively couples to at least one additional FCoE N_Port through the Ethernet fabric. The FCoE N_Ports may be implemented within a disc storage drive, a host bus adapter, and/or an FCoE switch. The capability of an N_Port to obtain this information allows a management module or processor at the N_Port to manage the Ethernet fabric.

摘要： A method for detecting a switch failure and managing switch failover in a Fibre Channel over Ethernet network. The plurality of Fibre Channel over Ethernet switches are connected to an intermediary Ethernet switch and to each other via an Ethernet connection. The intermediary Ethernet switch is different from the plurality of Fibre Channel over Ethernet switches. A plurality of end polls are also connected to the intermediary Ethernet switch. A failure is detected in a first switch in the plurality of Fibre Channel over Ethernet switches. The first switch is associated with a first end port in the plurality of end ports. A failure notification is sent to the first end port using the intermediary Ethernet switch. The failure notification might specify a second switch destination and an identification of the first switch. A fabric login is exchanged between the first end port and the second switch.
