Can perform in the computer system of such as one group of computer executable instructions in the step shown in the process flow diagram of accompanying drawing.Further, although show logical order in flow charts, in some cases, can be different from the step shown or described by order execution herein.
The executive agent of the embodiment of the present invention is main control system, and this main control system can be the such as intelligent control device such as computing machine, mobile phone, but is not limited to this.
The method that the embodiment of the present invention relates to, to be intended to solve in prior art when using ITP instrument to server, if do not insert ITP instrument before, do not support the hot plug of ITP instrument when breaking down, then cause developer or maintenance personal cannot the technical matters of fault of diagnostic processor yet.
The schematic flow sheet of the diagnostic method embodiment one of the processor fault that Fig. 1 provides for the embodiment of the present invention.The diagnostic method of what the present embodiment related to is processor fault obtains the value of register in described processor by connecting with server, determines the detailed process of the fault type of described processor according to the value of register in described processor.As shown in Figure 1, the method comprises:
S101, with server set up network connection relation;
Concrete, main control system sets up network connection relation by network connector and server, and can obtain the duty in server in real time, disconnects if find that there is network, main control system then can be attempted being connected with server, till establishing network connection relation with server always.
S102, send request the instruction of reading register in described processor, read the value of register in described processor;
Concrete, main control system is being determined to be connected with the network of server normally, the instruction of register in reading processor can be sent request, this reading command is used to indicate the value that server reads register in described processor, optionally, this reading command can, for having the message of any frame structure, also can be the order of arbitrary form.
The value of register in main control system reading processor, this register can be status register, is only reading mode, and wherein, in processor, the value of register can be that the form of packet sends to main control system, and such transmission speed is faster.
S103, determine the fault type of described processor according to the value of register in described processor, export described processor fault type.
Concrete, the packet of the value about register in processor that main control system reception server sends, decompress(ion) can be carried out, can from the addressing, running status etc. of the value reflection processor of register, and then determine whether the processor in server has fault, if there is fault, then export the fault type of this processor, described fault type comprises locating information and error information; Described locating information is the positional information of processor, and described error information is the error message of the processor of described transmission fault.Such as: No. 1 Memory Controller Hub fault of processor, No. 1 Memory Controller Hub abnormal state, wherein No. 1 Memory Controller Hub is locating information, and abnormal state is error information.This fault type can be shown by the display page of main control system, such as: fault type form can be Register1error, and the concrete way of output can decide according to actual conditions, but is not limited thereto.
The diagnostic method of the processor fault that the embodiment of the present invention provides, be connected by setting up network with server, send the instruction of the value of register in reading processor, to make it possible to the value of register in receiving processor, obtain the running status of described processor, and the running status of processor is analyzed, thus carry out diagnostic processor and whether break down and concrete fault type, and the fault type of output processor.The embodiment of the present invention, without the need to using ITP instrument, is also not limited to the space distribution distance of physical environment or server, can the fault of real-time diagnosis processor, simple to operate, saves cost, and then can Deterministic service device reliability of operation.
Further, on the basis of above-described embodiment, above-mentioned steps 101 is specially: the baseboard management controller to described server sends Network Expert Systems message, receives the network connection state of the baseboard management controller feedback of described server;
Judge that whether described network connection state is normal, if normally, then determine to set up network connection relation, if abnormal, then continue to send described network state detection message until determine that setting up network with described server is connected.
Concrete, baseboard management controller (the BaseboardManagementController of server, be called for short: BMC) be the special processor of server, be used for the ruuning situation of monitoring server inside, main control system sends Network Expert Systems message to the baseboard management controller of described server, whether this Network Expert Systems message is used to indicate main control system can set up good network connection relation with server, main control system can send Network Expert Systems message to server according to assigned frequency (such as 60 seconds for cycle) and monitor, the network connection state of the baseboard management controller feedback of real-time reception server, and the network connection state of feedback is judged, the ultimate principle of this monitoring method is similar to the ping function that windons system carries, object is in order to whether the main frame of another in test network can arrive, usually a echo request message can be sent, the echo response to be returned such as then, echo response is judged, if echo response represents that network connection state is normal, then determine that establishing network connects, if echo response represents that network malunion is normal, then can send echo request message according to the frequency of specifying always, until determine to connect normally, thus can ensure that the connection of main control system and server is normal.
Further, on the basis of above-described embodiment, above-mentioned steps 102 is specially: send the instruction of reading register in described processor to server chips group, and receive the feedback data that described server chips group sends, described feedback data comprises the state value of described register; Judge the state value of described register, if state value is when to be described register readable, the value of register in described processor is then read by the IPMI of server, if state value when to be described register not readable, then continue to send read register in described processor instruction until determine the value that can read described register.
