摘要： A computer program product for subnet management in virtual host channel adapter topologies 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 add a new logical host channel adapter (HCA) to the subnet, updating a logical switch port topology control block to reflect a pointer to the new logical HCA, and updating a port topology control block of the logical HCA to reflect a pointer to the logical switch port.

摘要： A method and system for a processor to efficiently accesses a remote First-in First-out (FIFO) buffer that is used to record event information. The access involves an interrupt mechanism when the FIFO transitions from the empty state, a mechanism for reading a FIFO entry including FIFO state information, and a mechanism for reading large areas of the FIFO while maintaining the pointers and interrupt protocols.

摘要： A method for diagnosing communications includes sending a message from a sending node to a receiving node. The sending node detects an error in the receiving node receiving the message. A force log request is sent from the sending node to the receiving node, the force log request including a request for the receiving node to log information. A force log response is received from the receiving node at the sending node, the force log response including the logged information. The sending node diagnoses the communications error in response to the force log response.

摘要： A method and system for I/O adapters that must rely on a central processor to handle all inbound link events to reduce the number of events signaled to the central processor with hardware state machines that sort out the significant link events and automatically generate the appropriate response on the outbound link thereby greatly reducing the central processor utilization. As optical links fail (unplugging the link is a failure) or when receiving multiple continuous sequences, numerous events must be filtered by the hardware state machines to limit the number of interrupts presented to the central processor.
