Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a flowchart of an expansion card repairing method according to an embodiment of the application.
The method for repairing the expansion card provided by the embodiment of the application can comprise the following steps:
step S101, detecting whether the hardware fault information of the expansion card is read or not in response to the fact that the driver cannot read the configuration space information of the expansion card, executing step S102 if the hardware fault information of the expansion card is read, and executing step S105 if the hardware fault information of the expansion card is not read.
In practical application, the fault types of the expansion card are various, when the fault of the expansion card is represented as configuration idle information of the expansion card which cannot be read by a driver, the fault may be a fault of the expansion card itself or a driving fault of the expansion card, in order to accurately analyze the fault reason, whether hardware fault information of the expansion card is read is further detected, specifically, the fault information of the expansion card is considered to be stored in a fault register, so that the fault register of the expansion card can be read, if the fault register is empty, it is determined that the hardware fault information of the expansion card is not read, at the moment, the driving abnormality of the expansion card can be determined, and correspondingly, if the fault register is not empty, it is determined that the hardware fault information of the expansion card is read, at the moment, the abnormality of the expansion card itself can be determined.
The expansion card of the present application refers to an interface card connected between a server motherboard and a hard disk drive, and may specifically be an SAS (SERIAL ATTACHED SCSI, serial communication technology-based storage interface standard) card or the like.
In practical application, the fault performance of the expansion card may be that the expansion card is lost due to link abnormality, for example, when the expansion card is lost due to PCI link abnormality, or the like, at this time, the in-place information of the expansion card may be obtained from the baseboard management controller (Baseboard Management Controller), the BMC), the in-place information is analyzed, if the in-place information characterizes the expansion card in place, the expansion card is powered on and powered off, so as to repair the expansion card in a hard repair manner.
In practical application, the fault performance of the expansion card may be that the register value of the drive read expansion card is abnormal, and at this time, the expansion card may be powered on and powered off to repair the expansion card in a hard repair manner.
It should be noted that the SAS card driver mainly includes two parts, a kernel driver and a user state driver, where the kernel driver is mainly used for mapping registers, configuration spaces and BAR (Base ADDRESS REGISTER, base register) spaces, and the user state driver mainly implements IO operations, and when a node is started and detects a card, the driver performs backup mapping on key resources during initialization. And the configuration space is a set of registers in the PCIe device for controlling the operation and properties of the device, including device ID, vendor ID, interrupt number, etc., by configuring these registers, control and setting of the device can be achieved. The BAR space is allocated and managed by the PCIe configuration space, each PCIe device has its own configuration space containing a set of BAR registers that inform the operating system and other devices of the resources required by the device, such as memory address ranges or I/O (Input/Output) port address ranges, the operating system, upon initializing the PCIe device, reads the values of the BAR registers and maps the corresponding resources into the system address space so that applications can communicate with the device by accessing these addresses.
Step S102, detecting whether the re-initialization operation is executed on the expansion card, if yes, executing step S103, and if not, executing step S104.
And step S103, performing power-on and power-off operation on the expansion card.
Step S104, reinitializing the expansion card.
In practical application, after reading hardware fault information of an expansion card, determining that the expansion card is abnormal, repairing the expansion card, in the process, detecting whether the expansion card is subjected to soft repair or not, namely detecting whether the expansion card is subjected to soft repair or not, if so, directly performing hard repair on the expansion card, namely directly performing power-on and power-off operation on the expansion card, and if not, performing soft repair and hard repair combined mode to perform fault repair on the expansion card, thereby ensuring repair success rate. It should be noted that, after the reinitialization operation is performed on the expansion card, the effective duration of the reinitialization operation may be flexibly adjusted according to the application scenario, and the application is not limited herein.
In a specific application scene, before the power-on and power-off operation is performed on the expansion card, whether the expansion card supports the power-on and power-off operation can be detected, if the expansion card supports the power-on and power-off operation is performed on the expansion card, if the expansion card does not support the power-on and power-off operation, the expansion card is isolated, and prompt information for performing the reinsertion operation on the expansion card is generated, so that fault repair is performed on the expansion card in a reinsertion manner.
In a specific application scenario, if the expansion card frequently fails, adverse effects are caused on the server, in order to avoid the situation, in response to the fact that the configuration space information of the expansion card cannot be read by a driver, after detecting whether hardware failure information of the expansion card is read, specifically, after performing power-on and power-off operation or reinitialization operation on the expansion card, updating a failure time value of the expansion card, detecting whether the failure time value exceeds a set threshold value, wherein the set threshold value can be flexibly determined according to actual needs, isolating the expansion card if the failure time value exceeds the set threshold value, releasing resources used by the expansion card, and generating prompt information for replacing the expansion card, so that the expansion card which is easy to fail is prevented from being reused in a mode of replacing the expansion card, and the performance stability of the server is ensured.
It should be noted that, the failure time value of the expansion card refers to the accumulated time value of the failure of the expansion card, and the accumulated time length of the failure time value of the expansion card can be determined according to actual needs. In a specific application scenario, when the number of the expansion cards on the server is large, the Serial Numbers (SN) and the failure time values of the expansion cards can be correspondingly stored, so that the failure time values of the corresponding expansion cards can be quickly and accurately searched through the serial numbers. In addition, after the configuration space information of the expansion card cannot be read in response to the drive, the failure time value of the expansion card may be updated first, and if the failure time value does not exceed the set threshold value, an operation of detecting whether the hardware failure information of the expansion card is read or not is performed.
The method for isolating the expansion card according to the fault sub-value can be applied to a scene of isolating the hot plug fault card, as shown in fig. 2, and can comprise the steps of inserting an expansion card into a server, driving to obtain a serial number of a current expansion card through a BMC, obtaining the fault sub-value of the current expansion card according to the serial number, detecting whether the fault sub-value is obtained, initializing the current expansion card normally if the fault sub-value is not obtained, detecting whether the fault sub-value exceeds a set threshold value if the fault sub-value is not obtained, isolating and prohibiting the use of the current expansion card if the fault sub-value exceeds the set threshold value, releasing resources used by the current expansion card, reporting a police, suggesting replacement of a new expansion card, and initializing the current expansion card normally if the fault sub-value is not exceeded the set threshold value.
Of course, the scheme of isolating the expansion card according to the failure time value can be applied to a scene of restarting the failure card isolation of the server node, as shown in fig. 3, the method comprises the following steps of starting service after restarting the node, driving to find the expansion card, executing driving initialization, driving to obtain the serial number of the current expansion card through the BMC, obtaining the failure time value of the current expansion card according to the serial number, detecting whether the failure time value is obtained, if not, initializing the current expansion card normally, if yes, detecting whether the failure time value exceeds a set threshold, if yes, isolating, prohibiting using the current expansion card, releasing resources used by the current expansion card, reporting police, suggesting to replace a new expansion card, and if not, initializing the current expansion card normally.
In a specific application scene, in the process of detecting whether the re-initialization operation is executed on the expansion card, real-time secondary values which are driven and cannot read configuration space information of the expansion card can be accumulated, in a set time length queue, real-time secondary values of preset time lengths are obtained from the head, the obtained real-time secondary values of preset time lengths are added to obtain target time lengths, whether the re-initialization operation is executed on the expansion card in the target time length before the current moment is detected, if yes, the re-initialization operation is judged to be executed on the expansion card, if no, the re-initialization operation is judged not to be executed on the expansion card, and in the set time length queue, the preset time length after the position is shorter.
According to the method, a time length queue is set, the preset time length after the position is located in the time length queue is shorter, after the real-time secondary value of configuration space information of the expansion card cannot be read by the driving is accumulated, the real-time secondary value preset time lengths are obtained from the head in the set time length queue, the obtained real-time secondary value preset time lengths are added to obtain the target time length, although the target time length is increased along with the increase of the real-time secondary value, the increase of the target time length is smaller and smaller, the target time length tends to be stable, the influence of the real-time secondary value on the target time length is lower, the rationality of the target time length is guaranteed, the real-time secondary value of the configuration space information of the expansion card cannot be read by the driving is detected, the fact that the real-time secondary value excessively influences a detection result is avoided, the process of whether the expansion card is subjected to the re-initialization operation is executed by the re-initialization operation is more reasonable is detected, and the rationality and effectiveness of repairing the expansion card by the re-initialization operation is improved.
Step S105, repairing the drive.
In practical application, after hardware fault information of the expansion card is not read, driving abnormality of the expansion card can be considered, and the expansion card can work normally by repairing driving of the expansion card.
In practical application, as shown in fig. 4, in the process of repairing the drive, the first backup memory mapped by the configuration space address of the expansion card can be determined, the isolation of the first backup memory is removed, the mapping relation between the configuration space address and the first backup memory is used as the configuration space address mapping result of the drive, the second backup memory mapped by the BAR space address of the expansion card is determined, the isolation of the second backup memory is removed, the mapping relation between the BAR space address and the second backup memory is used as the BAR space address mapping result of the drive, the third backup memory mapped by the register address of the expansion card is determined, the isolation of the third backup memory is removed, the mapping relation between the register address and the third backup memory is used as the register address mapping result of the drive, the fourth backup memory is determined, the fourth backup memory is used as the DMA (Direct Memory Access, direct access memory) address of the drive is used as the DMA (Direct Memory Access) of the drive, the drive is used for directly sending data to the corresponding to the address without using a central processing unit, after that the migration of the corresponding to the address is completed, the normal operation of driving the DMA address is performed, and the normal operation of the driver is performed to the address of the new IO address is ensured, and the I/O address is continuously mapped to the address of the drive and the new memory is performed.
According to the implementation process, the application considers that the essence of the drive initialization expansion card is to establish the mapping relation between the memory and the configuration space address, the BAR space address, the register address and the DMA address, so that corresponding backup memories are respectively set and isolated for the configuration space address, the BAR space address, the register address and the DMA address, when the drive is normal, the expansion card can be operated through the currently used memory, when the drive is abnormal, the isolation of the backup memories can be released, so that the backup memories can be normally applied, the backup memories are respectively used as the mapping result of the corresponding addresses of the expansion card, and the IO instruction of the drive is migrated to the DMA address, so that the drive can normally operate the expansion card through the backup memories, and the abnormal condition that the drive cannot read the configuration space information of the expansion card is relieved. On the basis, the configuration space address, the BAR space address and the register address are respectively mapped to new memories, and the new memories are isolated, so that the driver is ensured to have backup memories which can be replaced, and the next abnormal repair of the driver is facilitated. In addition, compared with the original scheme for initializing the expansion card, the original scheme for initializing the expansion card can stop related IO operation, namely the running IO operation returns to failure, which can cause short interruption of service, and by the scheme, after the problem occurs in driving, the remapping memory is directly used, the IO is directly switched into the new DMA memory, the initialization of the drive is not needed, the related IO operation is not needed to be stopped, the problem of IO interruption is avoided, and the repair of the drive fault can be realized under the condition that a user has no sense.
In a specific application scenario, in the process of initializing the expansion card by the driver, a corresponding backup memory can be created for the expansion card, as shown in fig. 5, i.e. before repairing the driver, the configuration space address can be mapped to two memories in the process of initializing the expansion card by the driver, one of the memories is isolated as a first backup memory, the other memory is used as a current used memory for driving to operate the configuration space address, the BAR space address is mapped to two memories, one of the memories is isolated as a second backup memory, the other memory is used for driving the current used memory to operate the BAR space address, the register address is mapped to two memories, one of the memories is isolated as a third backup memory, the other memory is used for driving the current used memory to operate the register address, and in order to drive two continuous memories, one of the memories is isolated as a fourth backup memory, and the other memory is used as a current used address for driving to process IO. In other words, in the process of driving the initial initialization expansion card, the corresponding address can be mapped to two memories to obtain the backup memory, and after the initialization is completed, the new memory can be directly mapped for the corresponding address to obtain the backup memory.
The application provides an expansion card repairing method, which is used for detecting whether hardware fault information of an expansion card is read or not in response to the fact that a driver cannot read configuration space information of the expansion card, detecting whether the hardware fault information of the expansion card is read or not, carrying out power-on and power-off operation on the expansion card if the hardware fault information of the expansion card is read, carrying out reinitializing operation on the expansion card if the reinitializing operation is carried out on the expansion card, and repairing the driver if the hardware fault information of the expansion card is not read. The application distinguishes the fault of the expansion card and the driving fault by detecting whether the hardware fault information of the expansion card is read or not under the condition that the configuration space information of the expansion card cannot be read by the driving, improves the identification accuracy of the fault condition of the expansion card, repairs the fault of the expansion card by reinitializing the expansion card and then powering on and off the expansion card under the condition of the fault of the expansion card, improves the success rate of repairing the fault, repairs the driving under the condition that the expansion card has no fault, ensures that the driving can normally operate the expansion card, and realizes the accurate identification of the fault condition of the expansion card and the accurate fault repair of the expansion card by executing the corresponding repair operation.
