摘要： A primary I/O adapter and a redundant I/O adapter of a data processing system are assigned to support access to a system resource. While the primary I/O adapter is in service and the redundant I/O adapter is not in service in providing access to the system resource, a fail over command is issued to remove the primary I/O adapter from service and place the redundant I/O adapter in service in supporting access to the system resource. While the redundant I/O adapter is in service and the primary I/O adapter is not in service in providing access to the system resource, diagnostic testing on the primary I/O adapter is performed. In response to the diagnostic testing revealing no fault in the primary I/O adapter, a fail back command is issued to restore the primary I/O adapter to service and to remove the redundant I/O adapter from service.

摘要： Methods and arrangements to monitor communication components such as a network adapters for activity, and identify components that have lower than normal levels of activity are provided. An identified communication component can become suspect component and a candidate for further testing, including different forms of interrogation. Process for interrogating candidates can include generating and sending test packets having the media access control (MAC) address of the candidate to the candidate and if activity is not detected subsequent to the interrogation, the candidate can be flagged as a failed component. Correspondingly, the component can be deactivated and removed from service. In a further embodiment, a backup component can be activated and assume the role previously held by the failed component.

摘要： A system translates a first group of cipher blocks based on a first encryption key to a second group of respective cipher blocks based on a second encryption key. Respective cipher blocks of the first and second groups represent the same data. The system comprises decryption hardware for sequentially decrypting the cipher blocks of the first group based on the first key. Encryption hardware is coupled to receive decrypted blocks output from the decryption hardware and sequentially encrypts the decrypted blocks into respective cipher blocks of the second group based on the second encryption key. A control unit controls the encryption hardware to encrypt the decrypted blocks into the respective cipher blocks of the second group while the decryption hardware decrypts cipher blocks of the first group. Consequently, decryption and encryption operations occur in parallel and the translation process is expedited.

摘要： A method, apparatus, and computer instructions for transferring data from a memory to a network adapter in a data processing system. The frame size for a transfer of the data from the memory to the network adapter is identified. If the frame size is divisible by a cache line size without a remainder, a valid data length is set equal to the length field. However, if the frame size divided by the cache line size results in a remainder, the length field is set to align the data with the cache line size. The data transfer is then initiated using these fields.

摘要： A method for Ethernet packet load balancing includes receiving a transmit packet for transmission on an Ethernet network. An offload adapter identifies a least busy port from a plurality of ports indicated in a port list, based on a byte count associated with each of the plurality of ports. The offload adapter determines whether the identified least busy port is in a working status. In the event an identified least busy port is in a working status, the offload adapter assigns the transmit packet to the identified least busy port and increments the byte count associated with the identified least busy port. In the event an identified least busy port is not in a working status, the offload adapter updates the port list and, based on a determination that there are additional working ports, assigns the transmit packet to one of the additional working ports.

摘要： A method, system, and computer program product are disclosed in a data processing system for avoiding data loss during network port recovery. A first network port is linked to a second network port via a network. The second network port transmits data to the first network port via the network. A determination is made that the first network port needs to be reinitialized. Prior to the first network port executing a re-initialization process, the first network port notifies the second network port to pause its data transmissions to the first network port.
