摘要： Provided are a computer program product, system, and method for updating zone information in a distributed switch of data forwarders. For each data forwarder, a sequence number is maintained for zone distribution messages sent to the data forwarder. A change to the ports in the network is detected comprising at least one of an allocation or deallocation of at least one port in the network. The sequence number for each data forwarder is incremented in response to detecting the change. For each data forwarder, a zone distribution message is generated indicating the at least one port allocated and/or deallocated, port information indicating each port in the network that may communicate with each other port, and the sequence number for the data forwarder. The generated zone distribution message is transmitted for each data forwarder to the data forwarder for which the zone distribution message was added.

摘要： A method for detecting a switch failure and managing switch failover in a Fiber Channel over Ethernet network. The plurality of Fiber 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 Fiber Channel over Ethernet switches. A plurality of end ports are also connected to the intermediary Ethernet switch. A failure is detected in a first switch in the plurality of Fiber 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.

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： A Fibre Channel over Ethernet (FCoE) device obtains knowledge of the configuration of an attached Ethernet fabric 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 information associated with an Ethernet fabric from the FCoE N_Ports and provides 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 replacing logical path resources, a host is able to replace a logical path it owns with a new logical path. Such a system is especially applicable when the condition of “out of resources” has been reached for a port. With this system, a host is guaranteed that it can replace a logical path it owns with a new logical path. It is not necessary for a control unit to have reached its maximum number of logical paths per port. A host is able to replace one logical path with a new logical path any time.

摘要： A remote copy system incorporates dynamically modifiable ports on the storage controllers such that those ports can operate either as a control unit link-level facility or as a channel link-level facility. When configured as a channel link-level facility, a primary storage controller can appear as a host processor to a secondary storage controller. Using dynamic switches coupled between primary and secondary sites, fewer ESCON communication links are required since the ESCON communication links can function either as a channel or as storage controller communication link.
摘要翻译：远程复制系统在存储控制器上结合动态可修改的端口，使得这些端口可以作为控制单元链路级设施或者作为信道链路级设施来操作。配置为通道链路级设施时，主存储控制器可以作为主处理器显示到辅助存储控制器。使用耦合在主站点和次站点之间的动态交换机，需要较少的ESCON通信链路，因为ESCON通信链路可以作为通道或存储控制器通信链路起作用。
