摘要： A baseboard management controller in a partitionable multi-processor system may perform operations including receiving a plurality of event notifications from the partitionable multi-processor system including one or more event notifications from a first partitioned node including a first subset of hardware devices of the multi-processor system and one or more event notifications from a second partitioned node including a second subset of the hardware devices of the multi-processor system, wherein each event notification identifies an event and a specific one of the hardware devices that experienced the event. The operations may further include receiving a request for an event log for the first partitioned node and providing the requested event log for the first partitioned node including only those event notifications that identify a hardware device that is included in the first partitioned node.

摘要： A server motherboard diagnosis method, system, and related circuit system. A management module of the server motherboard and peripheral devices managed by the management module are capable of being powered by a server power source and a USB port. In response to the management module and the peripheral devices being powered by the USB port, a power supply line of the server power source is isolated, as by: identifying the peripheral devices, in response to the management module and the peripheral devices being powered by the USB port; for each of the identified peripheral devices, initializing the peripheral device, and then shutting down the power supply of the peripheral device; establishing a communication between the management module and a diagnosis host through the USB port; and executing a command in response to the command being received from the diagnosis host.
