摘要:
The aspects of the present invention provide a computer implemented method, an apparatus, and a computer usable program code for identifying a service processor with current setting information. First stored information for a service processor is retrieved from a first memory in the first service processor. Second stored information for the service processor is retrieved from a second memory in a data processing system to which the service processor is connected. The first stored information is compared with the second stored information to form a comparison as to whether the service processor was previously connected to the data processing system and to determine whether the service processor was a last service processor to fully communicate with system firmware in the data processing system. The service processor has current setting information if the service processor was previously connected to the data processing system and was the last service processor to fully communicate with the system firmware.

A method, a system and a computer program product for selecting a primary controller for a server system based on the services offered by each controller. A primary controller designator (PCD) utility determines the relative importance of a controller based upon the services provided by the controller and the weighted importance assigned to these services. The PCD utility classifies the services provided by a system-controller according to the following: (1) the number of OS partitions a system-controller is able to communicate with; and (2) the number of hardware devices that a controller has access to. The importance of the services is determined by the host OS partition information and the degree of importance of a partition that utilizes/requires the particular service(s). The PCD utility designates a controller as a “Primary” if the designated “Primary” is capable of providing services that are required for the most important OS partitions, according to the classification of controller services.

A method, system, and computer usable program product for managing multi-node multi-version systems are provided in the illustrative embodiments. A process associates a version identifier with a first version of data available at a first node in the multi-node multi-version system. The version identifier corresponds to the first version of the data. The data includes an update. The process sends the data and the associated version identifier to a second node without learning a second version of data available at the second node. In one embodiment, the first version of data may be a subset of the second version of data. In another embodiment the second version of data may be a subset of the first version of data. The process repeats the sending for each update at the first node.

An apparatus, program product and method effectively virtualize a hardware device shared between multiple processors by a file accessible by a processor such that access to the hardware device may be controlled via a lock associated with the file. By doing so, file-based locking, e.g., as provided by a file locking facility in an operating system running on a processor, may be used to control access to the hardware device on behalf of the processor.

A method, computer program product, and system for the staged integration of a remote entity and the simultaneous publishing of services is provided. The integration of the distributed remote entities is broken into five stages, with appropriate events published after each stage. Each of the five stages is initiated only if the previous stage completed successfully. The first stage is the initiate discovery phase. The first event is the discovery start event. The second stage is the discovery completed phase. The second event is the discovery completed event. The third stage is the basic software services verified phase. The third event is the basic software verification completed event. The fourth stage is the basic hardware services verified phase. The fourth event is the basic hardware verification completed event. The fifth stage is the extended hardware services verified phase. The fifth event is the full integration of disturbed entity event.

A computer implemented method, a tangible computer readable medium, and a data processing system intelligently propagate link status information received by a blade server to the various ports of an embedded multi-port switch. The link status of a switch port in an external switch module can be communicated to the operating systems of individual blade servers that are affected by that link status. When an external switch module is unplugged from a server blade chassis, the bus controller broadcasts a link down event, such as a link down interrupt, to the individual server blades where it is received by the embedded multi-port switch for those server blades. The embedded multi-port switch translates the link down interrupt into a hardware link down event, and forwards the hardware link down event to the other elements connected to the embedded multi-port switch.

A JTAG bus cross point switching device that is commanded by the same bus which it configures. In a preferred embodiment a JTAG chain includes a cross point switching device that is capable of adding, omitting, or rearranging devices on a JTAG bus. The switching device itself is controlled by commands on the JTAG bus which it configures.

A method, system, and computer usable program product for updating firmware without disrupting service are provided in the illustrative embodiments. An updated firmware code is sent to a first firmware component and a second firmware component. The first firmware component is a primary firmware component and the second firmware component is a backup firmware component in a redundant firmware configuration. The updated firmware code is installed in second firmware component. The updated firmware code is activated in a third firmware component. The third firmware component is in communication with the first firmware component. A fail-over from the first firmware component to the second firmware component is performed such that a user communicating with the data processing system and receiving a service using the first firmware component continues to receive the service using the second firmware component without a disruption in the service.
摘要:
A method, system and computer program product for remotely debugging a malfunctioning node controller of a node in a distributed node network through a functioning node controller of the same node. The method comprises establishing a serial link between the malfunctioning node controller and a functioning node controller and configuring the functioning node controller as a virtual console by the remotely-located central data processing system (DPS). The method further includes receiving, via an internal Fru Support Interface (FSI) link, serial data from the malfunctioning node controller through the virtual console, and debugging, by the DPS, a failure condition of the malfunctioning node controller, in response to receipt of the serial data through the virtual console.
