摘要： A state of an input/output (I/O) operation in an I/O processing system is determined. A request for performing the I/O operation is received from an I/O operating system at a channel subsystem and forwarded to a control unit controlling an I/O device for executing the I/O operation. After a predetermined amount of time passes without receiving indication from the control unit that the I/O operation is completed, an interrogation request is received at the channel subsystem from the I/O operating system for determining the state of the I/O operation. An interrogation command is sent from the channel subsystem to the control unit. A response is received from the control unit, the response indicates a state of the I/O device executing the I/O operation, a state of the control unit controlling the I/O device executing the I/O operation, and the state of the I/O operation being executed.

摘要： An apparatus, system, and method are disclosed for establishing a point-to-point connection using Fibre Channel over Ethernet (FCoE). The point-to-point connection is established as part of the FCoE Initialization Protocol (FIP). A first computing device sends a FIP discovery solicitation to a predefined address such as ALL-FCF-MACs. The first computing device also listens to the local ALL-FCF-MACs address and determines whether or not there are any switches in the fabric connecting the first computing device and the second computing device. If there are no switches, the first computing device sends a second FIP discovery solicitation with a point-to-point indicator. If the first computing device receives a similar FIP discovery solicitation from the second computing device, it sends a FIP discovery advertisement with the point-to-point indicator. The first computing device and second computing device then perform fabric login and establish a point to point connection.

摘要： Provided are a computer program product, system, and method for supporting non-delivery notification between a switch and device in a network. A login with a switch is initiated including a test service parameter requesting a non-delivery notification service to cause the switch to return a non-delivery notification in response to a test path request indicating a destination node that is unavailable. Indication is made that the test service is available for the login in response to receiving a reply from the switch that the switch accepts the login with the non-delivery notification service. The test path request is sent to the switch to determine whether the destination node is available in response to determining that the non-delivery notification service is available for the switch login. The non-delivery notification is received from the switch in response to the switch determining that the destination node to which the test path request is directed is unavailable.
