Abstract: In one aspect of the present description, in an input/output (I/O) device having multiple CPUs and multiple I/O ports, a cycle of I/O port rotations is initiated in which each port rotation of the cycle includes rotating an assignment of at least one I/O port from one CPU to a different CPU of a plurality of the CPUs. In the illustrated embodiment, an I/O port assignment for each CPU of the plurality CPUs is rotated for at least a portion of the cycle. Other features and aspects may be realized, depending upon the particular application.

Abstract: A method for managing storage space in a storage port queue includes establishing a watermark for the storage port queue. The method further receives, at the storage port associated with the storage port queue, a command having an initiator-target-LUN (ITL) nexus associated therewith. Upon receiving the command, the method determines whether the used space in the storage port queue has reached the watermark. In the event the used space has not reached the watermark, the method processes the command. In the event the used space has reached the watermark and a specified number of commands for the ITL nexus are already present in the storage port queue, the method rejects the command. Otherwise, the method may process the command. A corresponding apparatus and computer program product are also disclosed herein.

Abstract: Systems and methods for detecting supported small form-factor pluggable (SFP) devices in an adapter are provided. One system includes multiple ports, each port configured to be coupled to a SFP device, a tracking device configured to store data representing a list of supported SFP devices for the adapter, and a processor coupled to each of the plurality of ports and the tracking device. The processor is configured to scan each port at start-up, determine if any of the ports is coupled to a non-supported SFP device, and disable any ports that are coupled to a non-supported SFP device. One method includes scanning each port at start-up, determining if any of the ports is coupled to a non-supported SFP device, and disabling any ports that are coupled to a non-supported SFP device. Also provided are computer storage mediums including computer code for performing the above method.

Abstract: A fabric login (FLOGI) in a Fiber Channel (FC) adapter is throttled. The system includes a first tracking mechanism, a second tracking mechanism, a switch, and an FC adapter. The FC adapter comprises three or more FLOGIs and a controller. First and second FLOGI requests are transmitted to the switch and indicate, via a first tracking mechanism, that a first FLOGI associated with the first FLOGI request and a second FLOGI associated with the second FLOGI request are active. A third FLOGI request is queued until the first FLOGI request or the second FLOGI request is processed by the switch and indicates, via a second tracking mechanism, that a third FLOGI associated with a third FLOGI request is queued.

Abstract: Provided are a method, system, and computer program product for managing monitored conditions in adaptors. An adaptor detects a condition comprising one of a plurality of monitored conditions and determines whether the detected condition is indicated on a recent condition list indicating conditions detected at the adaptors. The adaptor communicates the detected condition to cause the detected condition to be included in the recent condition list available at the adaptors in response to determining that the detected condition is not indicated in the recent condition list. Further, a system receives from one of the adaptors indication of a detected condition comprising one of a plurality of monitored conditions that is not indicated on a recent condition list. The received indicated condition is added to the recent condition list to produce an updated recent condition list. Transmission is caused of the updated recent condition list to the adaptors.

Abstract: Systems and methods for scanning ports for work are provided. One system includes one or more processors, multiple ports, a first tracking mechanism, and a second tracking mechanism for tracking high priority work and low priority work, respectively. The processor(s) is/are configured to perform the below method. One method includes scanning the ports, finding high priority work on a port, and accepting or declining the high priority work. The method further includes changing a designation of the processor to TRUE in the first tracking mechanism if the processor accepts the high priority work such that the processor is allowed to perform the high priority work on the port. Also provided are computer storage mediums including computer code for performing the above method.
