Description
Technical Field
The present invention relates to error status data of a computer device, and more particularly, to a method for providing error status data of a computer device.
Background
A computer device currently used as a server usually includes a baseboard management controller (bmc) system, which is used to provide error status data of the computer device to assist an administrator in managing the computer device.
When the BMC receives an error notification such as a fatal error (CATERR) notification from the CPU, the BMC reads the error status data stored in an internal register of a CPU of the computer device. In practice, however, the computer device is restarted upon occurrence of an abnormality, such as a fatal error (CATERR), thereby clearing the cpu of the error status data corresponding to the abnormality. It should be noted that the operation of the bmc system is not affected when the computer device is restarted. Therefore, if the cpu receives the error notification from the bmc after the computer device is restarted, the error status data, such as Machine Check Architecture error status (mac error status) data, stored in the internal registers of the cpu read and stored by the bmc does not correspond to the error status data when the abnormal condition occurs, but corresponds to the error status data after the computer device is restarted, and therefore, the administrator of the computer device may not correctly analyze the cause of the abnormal condition of the computer device according to the error status data provided by the bmc.
Disclosure of Invention
Therefore, an object of the present invention is to provide an error status data providing method.
To achieve the above object, the method for providing error status data according to the present invention is implemented by a baseboard management control system included in a computer device, the computer device further includes a central processing unit electrically connected to the baseboard management control system, the method for providing error status data includes the following steps:
(A) reading and storing the error status data stored in the CPU;
(B) determining whether the error status data contains at least one of a plurality of specified errors;
(C) continuing to execute step (A) when the error status data is determined not to contain the at least one specific error; and
(D) when it is determined that the error status data includes the at least one specific error, the error status data previously stored in step (a) is transmitted to a user upon receiving a data request from the user.
Compared with the prior art, the error state data providing method of the invention reads and stores the error state data when the computer device generates the at least one specific error by the baseboard management control system, and transmits the error state data when the computer device generates the at least one specific error to the user terminal after receiving the data request from the user terminal under the condition that the error state data contains the at least one specific error, so as to prevent the error state data when the computer device generates the at least one specific error from being cleared before being stored by the baseboard management control system, and further enable a manager to analyze the reason of the error of the computer device according to the error data received by the user terminal.

[ detailed description ] embodiments
Referring to fig. 1, the embodiment of the error status data providing method of the present invention is implemented by a baseboard management control system 11 included in a computer device 1. The bmc 11 is connected to a user terminal 2 via a communication network 100. The computer device 1 further includes a central processing unit 12 electrically connected to the baseboard management control system 11, in this embodiment, the computer device 1 is, for example, a server, the baseboard management control system 11 includes, for example, a non-volatile memory module 111, a communication module 112 connected to the communication network 100, and a processing module 113 electrically connected to the non-volatile memory module 111 and the communication module 112, and the central processing unit 12 is, for example, a processor manufactured by Intel corporation.
Referring to fig. 1 and 2, an embodiment of the error status data providing method of the present invention includes the following steps.
In step 31, the processing module 113 of the bmc 11 reads and stores the error status data stored in the internal register (not shown) of the cpu 12 through a Platform Environment Control Interface (PECI), wherein the error status data is related to the computer device 1. In this embodiment, the error status data includes machine check architecture error status data. In addition, the processing module 113 of the bmc 11 stores the error status data by updating the previous error status data previously stored in the nonvolatile memory module 111 to the currently read error status data.
In step 32, the processing module 113 of the bmc 11 determines whether the error status data (i.e., the error status data stored in the non-volatile memory module 111) stored therein contains at least one of a plurality of specific errors. The specific errors are at least one of error types consistent with a hit error (CATERR), an Uncorrectable peripheral interface error (Uncorrectable PCI error), a hit peripheral interface error (total PCI error), a system management interrupt timeout (SMI timeout), a Parity Error (PERR), and a System Error (SERR). When it is determined that the error status data includes the at least one specific error, the flow proceeds to step 33. Otherwise, the flow proceeds to step 34.
In step 33, after the processing module 113 of the bmc 11 receives a data request from the user 2 via the communication module 112, the processing module 113 of the bmc 11 transmits the error status data previously stored in step 31 to the user 2 via the communication module 112. In another embodiment of the present invention, the method for providing error status data further comprises a step 30 (see fig. 3) before the step 31, in which the processing module 113 of the bmc 11 determines whether the computer device 1 has been restarted within a reference time period before a current time. When it is determined that the computer device 1 has been restarted within the reference time period before the current time, the flow proceeds to step 33. Otherwise, the flow proceeds to step 31.
In step 34, after the processing module 113 of the bmc 11 counts a default time period, the process proceeds to step 31.
It should be noted that, in actual use, when the conventional bmc 11 detects that the computer device 1 is not operating normally, it stores a System Event Log (SEL) related to the computer device 1 to assist the administrator to know the reason of the abnormal operation of the computer device 1. However, in addition to the system event log, the administrator must also refer to information such as machine check architecture error status data to understand the reason of the abnormal operation of the computing device 1. When the error status data contains the at least one specific error, the computer device 1 will not function normally, and the system event log will contain some abnormal information, when the administrator knows from the system event log that the computer device 1 is not operating properly due to some abnormal information, the administrator will use the client 2 to issue the data request for the error status data of the non-volatile memory module 111 stored in the baseboard management control system 11 to the baseboard management control system 11, the bmc 11 returns the error status data stored in the non-volatile memory module 111 inside the bmc 11 according to the data request, the administrator thereby obtains the error status data stored by the bmc 11 when the at least one specific error occurs.
After the administrator uses the client 2 to issue the data request and obtains the error status data stored by the bmc 11 when the at least one specific error occurs, the bmc 11 will continue to execute steps 31-32 (see fig. 2) or 30-32 (see fig. 3), in other words, before the bmc 11 receives the data request of the error status data stored in the non-volatile memory module 111 inside the bmc 11, the bmc 11 will not periodically read any error status data from the register inside the cpu 12 or store the error status data stored in the register inside the cpu 12 into the non-volatile memory module 111 inside the bmc 11, so as to prevent the error status data stored in the non-volatile memory module 111 inside the bmc 11 when the at least one specific error occurs from being overwritten or destroyed in the storage process.
In the case that the error status data does not contain the at least one specific error, the bmc 11 counts the default time period, e.g., 50ms later, the steps 31 to 32 (see FIG. 2) or the steps 30 to 32 (see FIG. 3) are continuously executed, since it takes more than 50ms for the computer device 1 to be rebooted due to the occurrence of the at least one specific error, therefore, the time period required for clearing the error status data including the at least one specific error in response to the reboot of the computer device 1 also exceeds 50ms, so that the bmc 11 automatically reads the error status data stored in the internal registers of the cpu 12 by periodically reading the error status data every 50ms, thereby, it is avoided that the error status data when the at least one specific error occurs is cleared before being stored by the bmc 11. Furthermore, since the baseboard management control system 11 is stored by the baseboard management control system 11 when the at least one specific error occurs and after the error status data has been transmitted to the user 2, will proceed to steps 31-32 (see figure 2) or steps 30-32 (see figure 3) ", i.e., before the error status data stored by the bmc 11 is transmitted to the user 2 when the at least one specific error occurs, the processing module 113 of the baseboard management control system 11 does not execute the steps 31-32 (see fig. 2) or the steps 30-32 (see fig. 3), so that, the error status data stored in the non-volatile memory module 111 inside the bmc 11 when the at least one specific error occurs can be prevented from being overwritten or damaged by the error status data subsequently read by the bmc 11. In other embodiments of the present invention, in addition to the bmc 11 periodically reading the error status data stored in the registers inside the cpu 12 to obtain the error status data, when the bmc 11 receives an error notification such as a fatal error (CATERR) notification from the cpu 12, the bmc 11 also reads the error status data stored in the registers inside the cpu 12 to obtain the error status data.
In summary, the method for providing error status data according to the present invention is provided, wherein the bmc 11 periodically reads and stores the error status data of the buffer inside the cpu 12, and when the error status data includes the at least one specific error, the bmc 11 temporarily stops the operation of periodically reading and storing any error status data from the buffer inside the cpu 12, and after receiving the data request from the user 2, transmits the error status data when the at least one specific error occurs to the user 2, so as to ensure that the administrator can obtain the error status data when the at least one specific error occurs, thereby achieving the objective of the present invention.
The above-mentioned embodiments and drawings are only preferred embodiments of the present invention, but not intended to limit the scope of the invention, and all equivalent changes and modifications made by the claims of the present invention should fall within the scope of the present invention.
