Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular, to a method, device, equipment and storage medium for monitoring the operation of a server FRU. Background Art

[0002] With the continuous development of Internet services, the hardware configuration of servers has become increasingly complex. For the increasingly flexible combination of server components, it is possible to detect the field replaceable units (FRUs) on the server to determine which components are in place, and then monitor the working status of the components in place. Considering that more and more components are connected to the Inter-Integrated Circuit (I2C), in order to avoid address conflicts, the erasable programmable read-only memories of multiple components can be connected to an I2C expander, and multiple I2C expanders can be further cascaded.

[0003] Currently, the existing method for monitoring the operation of a server FRU usually controls the main control chip of the Baseboard Management Controller (BMC), scans the erasable programmable read-only memories with FRU information on the I2C based on a pre-set I2C expander cascade configuration file to obtain the FRU devices on the server, and then indirectly monitors the operation of each FRU device by managing each I2C expander. However, in the prior art, based on the pre-set I2C expander cascade configuration file, only fixed component configurations are supported, and it is impossible to adapt to the dynamically changing server component configurations. Secondly, indirectly managing FRU devices through I2C expanders will increase the development complexity of the monitoring program. Summary of the Invention

[0050] Embodiment 1

[0051] Figure 1 This is a flowchart of a method for monitoring the operation of a server FRU according to Embodiment 1 of the present invention. This embodiment is applicable to the situation of detecting and monitoring the operation of each component of the server during the BMC startup phase. This method can be executed by a running monitoring device of the server FRU. The running monitoring device of the server FRU can be implemented in the form of hardware and / or software. The running monitoring device of the server FRU can be configured in an electronic device. Typically, the electronic device can be a computer device or a server. As Figure 1 shown, the method includes:

[0052] S110. Obtain the connection topology of the integrated circuit bus I2C expander corresponding to the server.

[0053] Among them, the I2C expander may include multiple channels, and each channel may be connected to multiple server components (such as Risers, hard disk backplanes, and power supply devices, etc.) or I2C expanders. Each server component can connect its own Electrically Erasable Programmable Read-Only Memory (EEPROM) chip to the I2C expander through a certain channel. Only when the corresponding channel is enabled can the BMC communicate with the corresponding EEPROM chip. Among them, the EEPROM chip can be a storage carrier for FRU information and communicate with other chips using I2C. In this embodiment, the number and connection relationship of the I2C expanders in the server are not specifically limited.

[0054] It should be noted that the addresses of the I2C expanders are all within a fixed address range (0x70 - 0x78). In this embodiment, all the currently included I2C expanders in the server and the connection relationship between the expanders can be detected based on the address range corresponding to the I2C expander, and an I2C expander connection topology can be established according to the connection relationship between the expanders.

[0055] S120. Obtain the driver programs corresponding to the I2C expanders according to the I2C expander connection topology, and generate virtual I2C buses matching each channel of each I2C expander through the driver programs corresponding to the I2C expanders.

[0056] In a specific example, a corresponding Linux driver program can be dynamically bound to each I2C expander according to the I2C expander connection topology; among them, the Linux driver program is used to create a corresponding virtual I2C bus for each channel of the corresponding I2C expander in the BMC system. Thus, for the EEPROM chips of the server components connected to each channel, the upper-layer monitoring program can directly communicate with them based on the corresponding virtual I2C bus.

[0057] S130. Based on the virtual I2C buses matching each channel of each I2C expander, obtain at least one Field Replaceable Unit (FRU) corresponding to the server and the operating status of each FRU.

[0058] Among them, the Field Replaceable Unit (FRU) can be a component that can be flexibly configured in the server, such as a hard disk backplane, a power supply device, etc.

[0059] Specifically, based on the virtual I2C buses matched to each channel, the stored information in the EEPROM chips of the server components connected to each channel can be read. After that, the stored information can be verified to determine whether it conforms to the data format of the FRU information. If it is detected that the stored information corresponding to a certain server component conforms to the data format of the FRU information, then this server component can be determined as an FRU device, and device information such as the device model and product name of this FRU device can be obtained based on the stored information.

[0060] After that, based on the virtual I2C bus with this FRU device, the corresponding operating status of this FRU device can be obtained to achieve the operation monitoring of the FRU device. For example, the status parameters of the FRU device can be obtained based on the virtual I2C bus. For example, temperature, voltage, etc. When it is detected that each status parameter is within the preset range of status parameters, the operating status can be determined as the normal status; if it is detected that there is a status parameter exceeding the preset range of status parameters, the operating status can be determined as the abnormal status.

[0061] The technical solution of the embodiment of the present invention obtains the connection topology of the integrated circuit bus I2C expander corresponding to the server, and according to the I2C expander connection topology, obtains the driver programs corresponding to each I2C expander, and through the driver programs corresponding to each I2C expander, generates the virtual I2C buses matched to each channel corresponding to each I2C expander; after that, based on the virtual I2C buses matched to each channel corresponding to each I2C expander, obtains multiple field replaceable units FRUs corresponding to the server and the corresponding operating status of each FRU. By dynamically detecting the I2C expander connection topology and binding the corresponding driver program to each I2C expander to establish the virtual I2C buses matched to each channel, the effective operation monitoring of the dynamically changing server FRUs can be realized, the direct management of the FRU devices can be realized, and thus the development complexity of the monitoring program can be reduced.

[0062] In an optional implementation manner of this embodiment, obtaining the connection topology of the integrated circuit bus I2C expander corresponding to the server may include:

[0063] By sending I2C expander query messages to each address within a preset address range, at least one primary I2C expander corresponding to the server is obtained;

[0064] By sending channel switching instructions to each of the primary I2C expanders, at least one primary channel corresponding to each of the primary I2C expanders is obtained;

[0065] Determine whether there is a secondary I2C expander for each of the primary channels. If not, based on each of the primary I2C expanders, establish the I2C expander connection topology corresponding to the server.

[0066] Among them, the preset address range can be the range of I2C extender deployment addresses. Typically, it can be 0x70 - 0x78. In a specific example, I2C extender query messages can be sequentially sent to each address within the preset address range. If a feedback confirmation message (e.g., ACK message) is received for the current address, it can be determined that there is an I2C extender at the current address. Thus, multiple primary I2C extenders corresponding to the server can be obtained. Among them, the primary I2C extender can be the I2C extender located at the top layer in the I2C extender cascade network.

[0067] Specifically, after obtaining each primary I2C extender, for each I2C extender, a channel switching instruction can be executed respectively, and according to the instruction execution result, the corresponding primary channels and the number of channels can be obtained. Further, it can be determined whether there is a subordinate I2C extender after each primary channel. In one case, if it is determined that there is no subordinate I2C extender after each primary channel, that is, the current server only includes one layer of I2C extenders, an I2C extender connection topology corresponding to the server can be directly created based on each primary I2C extender.

[0068] In this embodiment, based on the preset address range and the channel switching instruction, accurate detection of the I2C extenders in the server can be achieved, thereby improving the accuracy of the obtained I2C extender connection topology.

[0069] In another alternative embodiment of this embodiment, after determining whether there is a subordinate I2C extender in each of the primary channels, it may further include:

[0070] If so, obtain each secondary I2C extender corresponding to each of the primary I2C extenders, and each secondary channel corresponding to each of the secondary I2C extenders, and re-determine whether there is a subordinate I2C extender in each of the secondary channels until it is detected that there is no subordinate I2C extender in each current-level I2C extender, and obtain all the I2C extenders corresponding to the server;

[0071] Establish an I2C extender connection topology corresponding to the server according to all the I2C extenders corresponding to the server.

[0072] In another case, if it is determined that there are lower-level I2C expanders for each first-level I2C expander, one or more second-level I2C expanders corresponding to each first-level I2C expander, and multiple second-level channels corresponding to each second-level I2C expander can be continuously obtained based on a preset address range and a channel switching instruction. After that, each second-level channel can be further detected for lower-level I2C expanders, and the above process can be repeated until it is detected that there are no lower-level I2C expanders for each current-level I2C expander, that is, the current-level I2C expander is the bottommost I2C expander, so as to finally obtain all the I2C expanders of the current server and the connection relationship between the I2C expanders. After that, an I2C expander connection topology corresponding to the server can be established based on the I2C expanders and the connection relationship between the I2C expanders.

[0073] In another alternative implementation manner of this embodiment, obtaining the driver corresponding to each I2C expander according to the I2C expander connection topology may include:

[0074] According to the I2C expander connection topology, obtain the data structure corresponding to each I2C expander, and according to the data structure corresponding to each I2C expander, obtain the driver corresponding to each I2C expander.

[0075] Among them, the data structure may include at least one of the address corresponding to the I2C expander, the number of channels corresponding to the I2C expander, the channel number through which the I2C expander is connected to the upper-level I2C expander, and the pointer pointing to the data structure corresponding to the upper-level I2C expander. The pointer can be used to query the information of the upper-level I2C expander. It can be understood that for the first-level I2C expander, the content of its corresponding data structure may only include the address corresponding to the I2C expander and the number of channels corresponding to the I2C expander.

[0076] In this embodiment, the connection topology relationship between the I2C expanders can be described by using the data structure corresponding to each I2C expander, and a corresponding driver can be dynamically bound to each I2C expander according to the data structure corresponding to each I2C expander. Among them, the driver may be a Linux driver, which is used to establish a corresponding virtual I2C bus for each channel of the I2C expander.

[0077] In this embodiment, by dynamically binding a corresponding driver to each I2C expander, it can be avoided that the monitoring program indirectly manages each FRU device through the I2C expander, and direct management of the FRU device can be realized, thereby reducing the development complexity of the monitoring program.

[0078] Secondly, in the prior art, for two types of components that use the same I2C slave device address and I2C bus number but different I2C expander chip models (such as PCA9543, PCA9546, PCA9548, etc.), it is impossible to achieve simultaneous support by pre-configuring the Linux kernel device tree. In this embodiment, by detecting the I2C expander connection topology in real time, it is possible to avoid the need to pre-plan the I2C expander chip model, I2C device address, I2C bus number, and cascading topology relationship in the kernel device tree in advance. Therefore, it can adapt to dynamic and changing configuration requirements.

[0079] Embodiment 2

[0080] Figure 2A The flowchart of a method for monitoring the operation of a server FRU provided in Embodiment 2 of the present invention. This embodiment further refines the above technical solution, and the technical solution in this embodiment can be combined with one or more of the above embodiments. As Figure 2A shown, the method includes:

[0081] S210. Obtain at least one primary I2C expander corresponding to the server by sending I2C expander query messages to each address within a preset address range.

[0082] S220. Obtain at least one primary channel corresponding to each of the primary I2C expanders by sending channel switching instructions to each of the primary I2C expanders.

[0083] S230. Determine whether there is a secondary I2C expander for each of the primary channels. If so, obtain each secondary I2C expander corresponding to each of the primary I2C expanders, and each secondary channel corresponding to each of the secondary I2C expanders, and re-determine whether there is a secondary I2C expander for each of the secondary channels until it is detected that there is no secondary I2C expander for each current-level I2C expander, and obtain all the I2C expanders corresponding to the server.

[0084] Optionally, if it is determined that there is no secondary I2C expander for each primary channel, the I2C expander connection topology corresponding to the server can be directly established according to each primary I2C expander.

[0085] S240. Establish the I2C expander connection topology corresponding to the server according to all the I2C expanders corresponding to the server.

[0086] S250. Obtain the driver corresponding to each I2C expander according to the I2C expander connection topology, and generate a virtual I2C bus matching each channel corresponding to each I2C expander through the driver corresponding to each I2C expander.

[0087] Optionally, after obtaining the I2C expander connection topology, the upper-layer monitoring program can also be used to directly manage the channel switches of each I2C expander to implement the detection and operation monitoring of FRU devices. Secondly, for the multi-thread scenario, locking processing can be performed for I2C expander operations.

[0088] S260. Based on the virtual I2C buses matched with the respective channels corresponding to the respective I2C expanders, obtain the slave devices corresponding to the respective channels, and the stored data matched with the memories corresponding to the respective slave devices.

[0089] Among them, the slave device can be a server component connected to each channel; the stored data matched with the memory corresponding to the slave device can be the device information stored in the EEPROM corresponding to the server component. In this embodiment, direct communication can be performed with the memories corresponding to the respective slave devices based on the virtual I2C buses matched with the respective channels, so that the stored data matched with the memories can be read.

[0090] S270. If it is detected that the stored data matched with the memory corresponding to the current slave device conforms to a preset data rule, then use the current slave device as the current FRU, and based on the virtual I2C bus matched with the channel corresponding to the current slave device, obtain the operating state corresponding to the current FRU.

[0091] Among them, the preset data rule can be the data format corresponding to the FRU information set in advance. For example, it can be the specified device name, device model, etc. In a specific example, the device name or device model field value can be extracted from the stored data, and the extracted field value is matched with the preset data rule. If it is determined that the match is successful, the current slave device can be determined as the current FRU. After determining that the current slave device is an FRU device, the operating state corresponding to the current FRU can be obtained based on the virtual I2C bus corresponding to the current slave device to perform targeted management and monitoring on the current FRU.

[0092] In addition, if it is detected that the stored data matched with the memory corresponding to the current slave device does not conform to the preset data rule, it means that the current slave device is not an FRU device, that is, flexible configuration cannot be performed. In this embodiment, for non-FRU devices, operation monitoring may not be performed.

[0093] In the technical solution of the embodiment of the present invention, after obtaining the I2C extender connection topology corresponding to the server, according to the I2C extender connection topology, obtain the driver corresponding to each I2C extender, and generate a virtual I2C bus matching each channel corresponding to each I2C extender through the driver corresponding to each I2C extender; then, based on the virtual I2C buses matching each channel corresponding to each I2C extender, obtain the slave devices corresponding to each channel and the stored data matching the memory of each slave device; if it is detected that the stored data matching the memory of the current slave device conforms to the preset data rule, then use the current slave device as the current FRU, and based on the virtual I2C bus matching the channel corresponding to the current slave device, obtain the operating state corresponding to the current FRU; by detecting the stored data based on the preset data rule, accurate judgment of the FRU on the server can be realized, and thus accurate monitoring of the operating state of the FRU can be realized.

[0094] In an optional implementation manner of this embodiment, obtaining the operating state corresponding to the current FRU based on the virtual I2C bus matching the channel corresponding to the current slave device may include:

[0095] Obtain the state parameters corresponding to the current FRU based on the virtual I2C bus matching the channel corresponding to the current slave device;

[0096] If it is detected that the state parameters corresponding to the current FRU meet the preset state detection conditions, then obtain the operating state corresponding to the current FRU as the normal state.

[0097] Among them, the state parameters may include temperature, voltage, current, etc. The preset state detection conditions may be the previously set state parameter ranges. When the state parameters corresponding to a certain FRU are within this state parameter range, it can be determined that the preset state detection conditions are met.

[0098] In this embodiment, the state parameters corresponding to the current FRU can be obtained in real time based on the virtual I2C bus, and it is judged whether the state parameters meet the preset state detection conditions; if so, it can be determined that the current FRU is in the normal state; and if the state parameters do not meet the preset state detection conditions, it can be determined that the current FRU is in the abnormal state.

[0099] In a specific implementation manner of this embodiment, the flow of the method for monitoring the operation of the server FRU can be as Figure 2BAs shown below. First, detect the I2C expanders to obtain each primary I2C expander and the number of channels of each I2C expander. Then, detect each channel separately and determine whether there is a subordinate I2C expander on the channel according to the detection result. If it is determined that there is a subordinate I2C expander, return to continue detecting the I2C expander until it is detected that there is no subordinate I2C expander on each channel of the current-level I2C expander.

[0100] If it is determined that there is no subordinate I2C expander on each channel, create an I2C expander connection topology, and bind the corresponding Linux driver to each I2C expander according to the I2C expander connection topology to generate a virtual I2C bus corresponding to each channel. Finally, based on each virtual I2C bus, detect and obtain each FRU device corresponding to the server, and monitor the operation of each FRU device.

[0101] The technical solution of the embodiment of the present invention can automatically detect all I2C expanders and FRU devices on the I2C bus during the BMC startup phase, which can improve the convenience of identifying and monitoring components. Compared with the conventional technology, there is no need to pre-set a specific configuration file, and only through the dynamic detection during program operation, the FRU device can be successfully discovered in a complex I2C topology, and accurate and efficient detection of the FRU on the server can be achieved. Secondly, when there is an I2C topology change caused by a component type change or a motherboard I2C topology change caused by a project design change, automatic adaptation can be achieved without any code modification, which can greatly reduce the maintenance workload.
