    摘要: Provided are a method, system, and program for managing communication between a first device and a second device and performing a recovery action at the second device in response to a credit depletion notification from the first device. The second device assigns credits indicating a number of outstanding frames the first device may transmit to the second device. The second device receives a first type or second type of credit depletion notification from the first device indicating that the first device needs additional credits to transmit further frames to the second device. The second device performs one of a plurality of recovery actions depending on whether the first type or second type of credit depletion notification was received.

    摘要: Provided are a method, system, and article of manufacture for credit depletion notification for transmitting frames between a port pair. Credits indicate a number of outstanding frames a first device may transmit to a second device. The credits are decremented in response to transmitting a frame to the second device. The credits are incremented in response to receiving a ready code from the second device indicating that the second device processed the transmitted frame. A determination is made as to whether additional credits are needed for communicating frames from the first device to the second device. A credit depletion notification is sent to the second device in response to determining that the additional credits are needed for communication with the second device.

    摘要: An apparatus for configuring a port in a multi-port communication adapter includes a quiesce module quiescing communications at one or more first I/O ports of a multi-port communication adapter while allowing communications at one or more second I/O ports of the multi-port communication adapter. A path module removes one or more logical paths between the one or more first I/O ports and one or more remote adapters in anticipation of taking the one or more first I/O ports offline. The offline module takes offline the one or more first I/O ports. The update module updates a port resource of the one or more first I/O ports while allowing a concurrent communication on the one or more second I/O ports of the multi-port communication adapter.

    摘要: Provided are a method, system, and article of manufacture, in which a logical path is established between a control unit and a channel over a fibre channel connection. Code for persistent information unit pacing is loaded into the control unit and the channel. An indicator is set in node descriptors of the control unit and the channel to indicate concurrent enablement of persistent pacing while retaining the established logical path between the control unit and the channel.

    摘要: A primary storage control unit receives an information unit from a remote host over a fibre channel connection. The primary storage control unit adjusts an information unit pacing parameter included in a response sent from the primary storage control unit to the remote host, wherein the information unit pacing parameter indicates the number of information units that the remote host is allowed to send to the primary storage control unit without waiting for any additional response from the primary storage control unit.
