Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this specification. Rather, they are merely examples of apparatus and methods consistent with some aspects of this specification as recited in the appended claims.

The present application provides a fault recording method, which is applied to a BIOS chip in a server, as shown in FIG. 1 , including:

S100. When it is determined that an uncorrectable fault occurs in the OS running in the server, obtain a first fault parameter in the server that is associated with the uncorrectable fault.

The internal structure of the server, as shown in FIG. 2 , includes a processor, a BIOS chip, a BMC, and a storage medium, and an OS runs in the processor. The BIOS chip can be set to a firmware priority mode, that is, after the SMI (Serial Management Interface, Serial Management Interface) interrupt is detected by the processor, the BIOS chip is coordinated to collect operating parameters. A section of storage space may be designated in the BIOS chip for temporarily storing the collected running parameters, or a section of storage space may be set in the memory to temporarily store the collected running parameters.

The storage medium is respectively connected to the BIOS chip and the BMC through the first bus, and the BIOS chip is respectively connected to the processor and the BMC through the second bus. The first bus may be an I2C (Integrated Circuit, Inter-Integrated Circuit) bus, an LPC (Low Pin Tree Interface, Low Pin Count) bus, and an eSPI (Enhanced Serial Peripheral Interface, enhancedSerial Peripheral Interface) bus, etc. compliant with IPMI One of the standard buses can be set according to actual needs. Specifically, the storage medium is a non-volatile storage medium, and data will not be lost after power off.

Correctable faults as well as uncorrectable faults may occur during the operation of the OS. Wherein, in the case of an uncorrectable fault, the OS is suspended and cannot continue to run, and the processor cannot continue to obtain the running parameter after the fault, and the running parameter may be referred to as the first fault parameter subsequently.

It should be noted that the first failure parameter can be selected according to the information reported by the SMI interrupt, such as processor failure, memory failure, PCIE (Peripheral Component Interconnect Express) failure, etc., then the BIOS chip corresponds to the device. The register obtains the operating parameters as the first fault information.

S101. Record the first fault parameter to a storage medium.

Since the OS will be reloaded when an uncorrectable fault occurs in the OS, at this time, the operating parameters under the fault condition will be lost, making it difficult to locate the fault. Therefore, after acquiring the first fault parameter, the BIOS chip can transmit the acquired first fault parameter to the storage medium through the first bus, so as to avoid the problem of loss of running parameters when the OS is reloaded.

S102. After the OS restarts, send the first fault parameter recorded in the storage medium to the BMC.

After it is determined that the OS is hanged, based on the mechanism in the server, such as a watchdog, etc., the OS is restarted and its operation is resumed.

After the BIOS chip detects that the OS is restarted, the BIOS chip can detect whether data is stored in the storage medium. If there is, it can be considered that an uncorrectable fault occurred before the OS restarts, and the BIOS chip outputs the first fault parameter stored in the storage medium to the BMC, or notifies the BMC to initiate a read request to the storage medium, so that the storage medium will send the first fault parameter to the storage medium. The fault parameters are fed back to the BMC. If not, the OS reboot can be considered normal and no action is required.

In addition, in the server, for a correctable failure of the OS running on the processor, the method further includes:

S103. When it is determined that a correctable fault occurs in the OS running in the server, acquire a second fault parameter in the server that is associated with the correctable fault.

S104. Send the second fault parameter to the BMC through the second bus.

Since the operation of the OS does not stop, the processor can record the operating parameters of these failures. Then, if the BIOS chip determines that the fault in the OS is a correctable fault, it can choose to actively read the second fault parameter from the processor or wait for the processor to send the second fault parameter, which can be selected according to actual needs without limitation.

Wherein, the second bus can be a video graphics matrix VGA (Video Graphics Array) bus, a local bus (Local Bus), etc. Specifically, since the transmission of the VGA bus can have a larger transmission space, it can be More operating parameters are sent to BMC for more accurate fault location.

In order to obtain the running parameters of the full cycle of the server, optionally, this method also includes:

S105A, when the server is started, various types of devices in the server are detected, and the startup parameters are recorded.

S106A. Send the second fault parameter to the BMC through the second bus; or,

S105B, when the server is working normally, acquire and record the normal parameters of various devices in the server at a preset time node;

S106B. Send the normal parameters to the BMC through the second bus.

When the server is started, the BIOS chip can perform self-test on the devices in the server, for example, detect the hard disk, memory, processor, and graphics card. At this time, the BIOS chip can be sent to the BMC through the second bus, so that the BMC can record. The startup mentioned here also includes a restart in the case of an uncorrectable failure of the OS.

Alternatively, multiple time nodes may be set in the OS of the server, for example, 12 hours may be set as a time node, and a timer may be set in the server. When the timer reaches the time node, the processor can start the BIOS chip to collect the operating parameters of the server, and the BIOS chip sends the operating parameters to the BMC for saving.

Correspondingly, the present application also provides a fault location method, which is applied to the BMC in the server, as shown in FIG. 3 , including:

S200. Acquire and record the first fault parameter in the server through the first bus.

The first failure parameter is an operating parameter written into the storage medium connected to the BMC and the BIOS chip in the server when an uncorrectable failure occurs in the OS running in the server.

S201. Determine a faulty device in the server according to the first fault parameter and the comparison parameter.

The comparison parameters have been recorded in the BMC, which may include startup parameters and normal parameters, and of course, may also include the first fault parameters generated during the last startup.

When the server fails, the first failure parameter stored in the storage medium is compared with the comparison parameters that have been stored in the BMC, so that it is easier and more efficient to determine which device the server failure occurs in, and can be analyzed according to the comparison. Identifying the specific cause of the failure allows staff to troubleshoot the problem faster.

Optionally, the method further includes:

S202, obtain and record the startup parameters and/or normal parameters in the server through the second bus.

The comparison parameters can include startup parameters and\or normal parameters, and the selection and acquisition of specific comparison parameters can be selected according to actual needs. The startup parameters are the operating parameters recorded when the server is started, and the normal parameters are the operating parameters of various devices in the server obtained and recorded at a preset time node when the server is working normally.

Step S201 is specifically: comparing the startup parameters recorded when the server is started twice adjacently, and determining the faulty device in the server.

For example, when the server is working normally, the BMC can capture display information through the graphics card through the second bus at a certain time interval, such as 5 minutes, and the display information can be used as a normal parameter. When the server sends an uncorrectable fault, the BIOS chip can capture the display information of the graphics card again, and store it in the storage medium as the first fault parameter.

After the OS is restarted, the BIOS chip detects that the storage medium has the first fault parameter, and transmits the first fault parameter to the BMC for recording. At this time, the BMC can compare the two displayed information. If the content of the two displayed information does not change, it means that the displayed content has not changed while the server is still running, and it can be determined that the graphics card may be A problem occurred, allowing staff to perform more specific testing of the graphics card.

For another example, when the server is started, the BIOS chip detects that the memory size is 4 gigabits, and the memory size is stored in the BMC as the content included in the startup parameters. When the OS is faulty, the BIOS chip obtains the memory size again, for example, 2 gigabits, and stores it in the storage medium as the content in the first fault parameter.

After the OS is restarted, the BIOS chip sends the first fault parameter to the BMC for recording, so that the staff can determine the decrease in the size of the memory during comparison, thereby locating the possible damage to the memory.

Of course, the first fault parameter does not only include display information and memory size, which are described here only by way of example.

As another operating parameter for locating the fault, optionally, the method further includes:

S203. Acquire and record the second fault parameter in the server through the second bus.

The second failure parameter is an operating parameter recorded when it is determined that a correctable failure occurs in the OS running in the server.

Step S201 , specifically: comparing the normal parameter and the second fault parameter, and determining the faulty device in the server.

Since the second fault parameter is an operating parameter corresponding to a correctable fault, it does not cause the OS to be directly suspended, so the processor can still transmit through the second bus. At this time, the second fault parameter will be written into the BMC via the BIOS chip.

The BMC can compare the normal parameters during the normal operation of the server with the second fault parameters, so as to locate the fault location corresponding to the second fault parameters.
