摘要： 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.

摘要： A method and data processing system for isolating a faulty component in a computer. A first microcontroller detects a fault in a component of a computer. Responsive to detecting the fault, the first microcontroller sets a first fault record for the component to pending fault, sets a second fault record for the first microcontroller to pending fault, and fails over to a second microcontroller. If the second microcontroller detects the fault in the component of the computer, then the first fault record for the component is set to permanent fault, and the second fault record for the first microcontroller is cleared. If the second microcontroller determines the component of the computer does not have the fault, then the first fault record for the component is cleared, and the second fault record for the first microcontroller is set to permanent fault.

摘要： A computer implemented method, a tangible computer medium, and a data processing system are provided for waking a blade server from an operational state of reduced power. When server blade enters the state of reduced power, a service firmware configures a multi-port blade switch of the server blade to direct incoming packets to the service firmware. The service firmware then polls for receipt of a Wake-on-Lan magic packet. When the Wake-on-Lan magic packet is received by the service firmware, the service firmware reconfigures the multi-port blade switch to direct incoming packets to a network interface card of the server blade. The service firmware then initiates a reboot of the server blade.

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.

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.

摘要： 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.
