Description

A sensor management method and device

technical field

The invention relates to the field of communication technology, in particular to a sensor management method and device.

Background technique

Inside the server, the BMC (Baseboard Management Controller; baseboard management controller) is used to generate data records based on the status information of each component reported by the sensor, and manage the data records.

In the intelligent management architecture of the server, the sensor is the smallest unit of status information of each component in the BMC management server. As the functions of the server become more and more powerful, the number of components in the server becomes larger and larger, so that the number of sensors that the BMC needs to manage becomes larger and larger. However, in the IPMI (Intelligent Platform Management Interface; Intelligent Platform Management Interface) 2.0 specification, users can access the valid range of sensor numbers under the jurisdiction of a BMC from 0 to 254, thus limiting the number of sensors under the jurisdiction of a BMC to Threshold number (ie 255).

At present, when the number of sensors under the jurisdiction of a BMC exceeds the threshold number, the method of reducing the number of sensors is usually used to solve the problem that the number of sensors under the jurisdiction of the BMC has an upper limit. For example, the number of sensors is reduced by deleting unnecessary sensors. With this technical solution, there is a problem that component status information reported by a specific sensor cannot be obtained. In addition, the number of sensors can be reduced by combining multiple sensors into one sensor. For example, sensors A to H monitor the status of eight memories respectively, that is, one sensor monitors the status of one memory. When any memory fails, The sensor corresponding to any one memory sends a failure warning to the BMC; at this time, the above eight sensors are combined into one sensor, and sensor A is used to monitor the status of the eight memories. If any one of the eight memories fails, sensor A will immediately Send fault warning to BMC. With this technical solution, since one sensor manages multiple memories and the sensor management granularity is relatively large, the BMC cannot accurately locate the failed memory according to the fault warning sent by the sensor.

It can be seen that, in the prior art, the sensor management granularity is relatively large, and the BMC cannot accurately locate the faulty memory problem according to the fault warning sent by the sensor.

detailed description

In order to solve the problem of inaccurate fault location in the process of managing each sensor in the server. In the embodiment of the present invention, the sensor identification of the corresponding state is stored in the storage list of each state contained in the BMC. When the user accesses the sensor identification stored in the BMC, if the state corresponding to the accessed sensor identification is active, it will contain The page table where the accessed sensor ID is located is switched from the active state to the preferred state. Adopting the technical scheme of the present invention, the sensors are classified according to the corresponding states of the sensors, so that the sensor identifications of different states are stored in different storage lists, because the number of sensor identifications that can be stored in each page table in the storage list is the threshold Therefore, corresponding sensors can be configured for each component to be monitored, and there is no need to limit the number of sensors under the jurisdiction of the BMC, thereby ensuring the granularity of sensor management and effectively improving the accuracy of fault location.

Referring to Fig. 1, it is a system architecture diagram in the embodiment of the present invention, wherein the BMC is located in the server, establishes a connection with the server through a hardware interface, and generates data records according to the status of the components to be monitored reported by each sensor in the server, and the database in the BMC Used to store the above data records. Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Figure 2, in the embodiment of the present invention, the detailed process of managing sensors is as follows:

Step 200: Receive an access instruction, and search for the state corresponding to the above sensor identifier from the locally stored storage list according to the sensor identifier carried in the access instruction.

In the embodiment of the present invention, after the BMC is powered on and started, the corresponding state is configured for each sensor under local jurisdiction, that is, the state corresponding to the sensor is configured as the initial state (Inactive), or the state corresponding to the sensor is configured as active state (Active), or configure the corresponding state of the sensor as the preferred state (Selected). Among them, when the BMC is started, the state corresponding to all the sensors under the local jurisdiction of the BMC is the initial state. When the state corresponding to the sensor is the initial state, the BMC does not scan it, and the sensor in the initial state does not generate event records. The sensor value corresponding to the sensor in the initial state cannot be accessed; when the BMC configures the state corresponding to the sensor in the local jurisdiction as the active state, the BMC continuously scans the sensor in the active state to obtain the event records generated by the sensor in the active state, but the user The sensor value corresponding to the sensor in the active state cannot be accessed; when the BMC configures the state corresponding to the sensor under the local jurisdiction as the preferred state, the BMC continuously scans the sensor in the preferred state to obtain the event records generated by the sensor in the preferred state. Provides access to sensor values corresponding to sensors in the preferred state. In the above process, the event record corresponding to the sensor is the status information corresponding to the monitored component, such as fault alarm information, hot plug event information, etc.; the sensor value corresponding to the sensor is the indication recorded by the sensor, such as the temperature sensor record temperature value etc.

Optionally, the BMC configures the corresponding state for each sensor under local jurisdiction respectively: according to the locally saved preset configuration policy, respectively configures the corresponding state for each sensor under local jurisdiction; or, receives the configuration input by the user command, and obtain the configuration information carried in the configuration command, and configure the corresponding status for each sensor under the local jurisdiction according to the above configuration information, wherein the user can input the configuration command through the terminal, and the terminal will send the configuration command to the server. The user can input configuration instructions through the operation interface corresponding to the server.

By adopting the above technical solution, the state corresponding to the sensor is adjusted according to the local preset configuration strategy of the BMC or the command configuration input by the user, which improves the flexibility of managing the server through the BMC; and, according to the user's needs, unnecessary sensors are not scanned, which reduces the system load. Non-essential overhead improves system work efficiency.

Optionally, there are three storage lists stored in the BMC, that is, an initial state table, an activated state table, and a preferred state table, and different storage lists store sensor identifiers of corresponding states. Wherein, when the state corresponding to the sensor is the initial state, the sensor identification is stored in the locally saved initial state table; when the corresponding state of the sensor is the active state, the sensor identification is stored in the locally saved active state table; When the state corresponding to the sensor is the initial state, the sensor identifier is stored in the locally saved activation state table.

Step 210: When the state corresponding to the above-mentioned sensor ID is the active state, switch the page table containing the above-mentioned sensor ID in the storage list to the preferred state.

In the embodiment of the present invention, when the state corresponding to the sensor identifier accessed by the user is not the preferred state but the activated state, the page table where the sensor identifier accessed by the user is located is switched from the activated state to the preferred state. Wherein, the number of sensor identifications contained in any page table in the storage list is not greater than the threshold number specified in the intelligent platform management interface specification, that is, the number of sensor identifications contained in any page table is not greater than 255.

Optionally, refer to FIG. 3 , which is a schematic diagram of the storage list in the embodiment of the present invention. In the storage list, the initial state table includes multiple page tables, and each page table can store less than or equal to 255 sensor identifiers, then The upper limit value of the initial state sensor identification that can be saved in the initial state table is n*255, where n is the number of page tables contained in the initial state table; the same as the above initial state table, the active state table contains multiple pages table, each page table can save less than or equal to 255 sensor IDs, then the upper limit value of the sensor IDs that can be stored in the active state in the active state table is n*255, and the n is the page contained in the active state table The number of tables; in particular, the preferred state table contains a page table, which can store less than or equal to 255 sensor identifications, then the upper limit value of the sensor identifications that can be saved in the preferred state table is 255, so as to meet IPMI2 The upper limit of the number of user-accessible sensors in a BMC-administered sensor specified in the .0 specification is 255. Wherein, each page table in the above-mentioned storage list corresponds to a page table number; the sensor ID stored in each page table may be a related sensor ID, for example, the sensor ID corresponding to the sensor ID stored in the same page table The functions are the same; the sensor ID stored in each page table can also be an irrelevant sensor ID.

Using the above technical solution, the sensor identifications of different states are stored in different storage lists, that is, the sensor identifications of different states are managed through different storage lists, each storage list can manage at least 255 sensors, three storage lists The number of manageable sensors will be far greater than the threshold number of sensors that can be managed by a BMC specified in the IPMI2.0 specification, thus avoiding the bottleneck problem of the number of sensors that can be managed by the BMC; and store the sensor identifications of different states in different In the storage list of the sensor, the management of the sensor is more convenient. The technical solution of the present invention can be applied to RAS (Reliability, Availability, and Serviceability; reliability, availability, and serviceability) application scenarios and large-scale server application scenarios.

Step 220: Output the page table including the sensor identification.

In the embodiment of the present invention, the BMC outputs the obtained page table including the sensor identification to the terminal, or outputs the obtained page table including the sensor identification to the operation interface of the server.

Further, since the BMC only scans the sensor whose attribute is the active state or the preferred state, the BMC obtains the event record corresponding to the sensor identification whose state is the active state or the preferred state, and the above-mentioned sensor identification; the sensor identification and the event corresponding to the sensor identification The records are bound, and the bound sensor ID and the event record corresponding to the sensor ID are stored as a data record in the local database.

In the embodiment of the present invention, since the number of sensors under the jurisdiction of one BMC is far greater than 255, and the storage lists stored by the sensor identifiers in different states are different. Therefore, if only the serial number of the sensor is used as the sensor ID for storage in the prior art, the sensor serial number in different storage lists may be the same, resulting in the problem of duplication of sensor IDs. It can be seen that, optionally, after the sensor identification is stored in the corresponding storage list, the sensor identification is updated, that is, the storage list identification corresponding to the sensor identification and the sensor serial number are added to the sensor identification; wherein, the storage list identification includes the storage list corresponding to Status and the page table number where the sensor ID resides. For example, the sensor serial number included in the sensor identifier is 36, and the storage list identifier is the page table 17 in the active state table, which means that the identifier of the sensor 36 is stored in the page table 17 of the active state table. Optionally, four bytes are used to save the above sensor identification.

Further, in the above-mentioned BMC, when the user needs to obtain the data record, the user can query it on the UI interface of the BMC through the IPMI command. Specifically, when the BMC receives the data record query instruction input by the user, it obtains the identification of the event record carried in the data record query instruction, and according to the identification of the event record, obtains the identification of the above-mentioned event record stored in the BMC local database Corresponding data record, wherein, the identification of the event record includes the time attribute corresponding to the event record, and the type attribute of the event record (such as fault alarm event, hot plug event, sensor output value exceeding threshold event, etc.); or, obtain the data record Query the sensor ID carried in the instruction, and according to the sensor ID, obtain the data record corresponding to the above sensor ID stored in the BMC local database, wherein the sensor ID is the sensor serial number and the storage list ID corresponding to the sensor ID. Optionally, when the user queries data records through an IPMI command, the IPMI command is a data record query command in SQL (Structure Query Language) format, and the BMC parses the data record query command in SQL format to obtain The identifier of the event record or the identifier of the sensor carried in the data record query instruction in the SQL format.

Using the above technical solution, the sensor identification in the storage list is bound to the event record, and the generated data record is stored in the BMC database, thereby avoiding the problem of data record confusion caused by the asynchronous storage list and event record, ensuring The synchronization of sensor identification and event records in the storage list in the BMC is improved, and the accuracy of data records generated based on the storage list and event records is improved.

Based on the above BMC, when the user needs to manage the data records in the storage list, the user sends an IPMI command to the BMC to manage the data records in the storage list. Specifically, when the BMC receives the data record management instruction input by the user, it acquires the sensor identifier carried in the data record management instruction; according to the data record management information carried in the above data record management instruction, the data record corresponding to the above sensor identifier Make adjustments.

Optionally, the BMC adjusts the data record corresponding to the sensor identifier, including deleting the data record corresponding to the sensor identifier, adding the data record, and changing the state corresponding to the sensor identifier and the corresponding data record.

The process of BMC adjusting the data record corresponding to the sensor ID is specifically: when the above data record management information is delete data record information, delete the data record corresponding to the sensor ID saved in the database, and delete the sensor ID in the storage list, that is Release the storage space occupied by the data records composed of sensor identification and event records; when the above-mentioned data record management information is adding data record information, obtain the sensor identification to be added, and add the sensor identification to be added to the preferred state table or active state In the table, the storage space is created in the preferred state table or the active state table, after the sensor ID to be added is added to the created storage space, the sensor ID is updated according to the storage space ID (that is, the storage list ID); when the above data record When the management information is to change the status corresponding to the sensor ID, obtain the sensor ID to be changed and the status change information, and store the sensor ID to be changed in the corresponding storage list according to the above status change information, and update the data corresponding to the sensor ID to be changed Record.

Optionally, changing the state corresponding to the sensor identification means changing the state corresponding to the sensor identification from the preferred state to the active state; or changing the state corresponding to the sensor identification from the active state to the preferred state.

Referring to Figure 4, according to the above state change information, the process of recording the sensor identification to be changed and its corresponding data includes:

The first case: if the state change information is to change the state corresponding to the sensor identification from the preferred state to the active state, then switch the storage list corresponding to the sensor identification from the preferred state to the active state, and update the sensor identification and the above-mentioned data saved in the database The data record corresponding to the sensor.

The second case: if the state change information is to change the state corresponding to the sensor identification from the active state to the preferred state, then switch the storage list corresponding to the sensor identification from the active state to the preferred state, update the sensor identification, and the above-mentioned information stored in the database The data record corresponding to the sensor ID.

By adopting the above technical solution, by storing the sensor identifications of different states in different storage lists, the user can adjust the corresponding states of the sensor identifications in the storage list through IPMI instructions, and adjust the data records in the database, thereby effectively improving This increases the flexibility of data record management.

Based on the above technical solution, as shown in FIG. 5, in the embodiment of the present invention, the process for the user to access the sensor identification through the IPMI command is:

Step 500: The BMC receives the first IPMI command input by the user, and acquires the storage list identifier carried in the IPMI command.

In the embodiment of the present invention, the aforementioned IPMI command may be an OEM (Original Equipment Manufacturer; original factory entrusted manufacturing) command, that is, an IPMI command in a custom format. For example, if it is necessary to access page table 0 of the active state table, the BMC receives the first IPMI command (set sensor page id=0) input by the user.

Step 510: The BMC configures the page table corresponding to the above storage list identifier as the preferred state, and sends a configuration success instruction to the terminal.

In the embodiment of the present invention, the BMC configures the page table corresponding to the storage list identifier as the preferred state, that is, switches to the page table interface corresponding to the storage list identifier. For example, after receiving the first IPMI command (setsensor page id=0) input by the user through the terminal, the BMC will switch to page table 0 and send a configuration success command (set sensor page id=0ok) to the terminal.

Step 520: The BMC receives the second IPMI command sent by the user, and obtains the serial number of the sensor carried in the second IPMI command.

In the embodiment of the present invention, if it is necessary to access the sensor 20 in the page table 0 in the active storage list, the BMC receives the second IPMI command (get sdr sensornum=0) sent by the user through the terminal.

Step 530: The BMC calls the above-mentioned sensor serial number from the above-mentioned preferred state table, and the terminal sends a calling success instruction.

In the embodiment of the present invention, if it is necessary to access the sensor 20 in the page table 0 of the active state table, the BMC calls the sensor 20 in the page table 0 of the active state table, and sends a calling success instruction (sdr sensornum=0) to the terminal. The user can change the status corresponding to the sensor ID through the sensor ID presented by the terminal.

In the embodiment of the present invention, the user can send the first IPMI instruction and the second IPMI instruction to access the sensor identification to the BMC. Optionally, the user can also send only one IPMI instruction to the BMC, which includes the storage list identification and the sensor serial number .

Based on the above technical solution, see FIG. 6, in the embodiment of the present invention, the process for the user to obtain the data record through the IPMI command is:

Step 600: The BMC receives the data record query instruction input by the user through the terminal, and acquires the identifier of the event record carried in the data record query instruction.

In the embodiment of the present invention, the above data record query command is an IPMI command. For example, the above data record query instruction may be in the following form: get sel info (sel id=XX), wherein, sel represents a time record, and sel id identifies the identifier of the event record.

Step 610: The BMC uses the identifier of the event record to call the data record corresponding to the identifier of the event record from the database.

Step 620: the BMC sends the above data record to the terminal.

In the embodiment of the present invention, after the BMC obtains the data record corresponding to the identifier of the above event record, it may send the data record to the terminal in the following form: return get sel info.

Further, referring to FIG. 7, in the embodiment of the present invention, the BMC configures the sensor in the initial state according to the configuration instruction input by the user as follows:

Step 700: Receive a configuration instruction, and obtain the initial state sensor identification carried in the configuration instruction and the configured state.

In the embodiment of the present invention, the configured state includes an active state and a preferred state.

Step 710: When the above configured state is the preferred state, store the sensor identification in the page table of the preferred state table; when the above configured state is the preferred state, store the sensor identification in the page table of the active state table .

In the embodiment of the present invention, as shown in FIG. 4, when the state corresponding to the above-mentioned sensor identification is configured as the active state according to the configuration instruction, a storage space is created in the activation state table, and the sensor identification is stored in the above-mentioned storage space, Correspondingly, if it is necessary to configure the sensor identification from the active state to the initial state, delete the sensor identification from the above-mentioned active state table; when the state corresponding to the above-mentioned sensor identification is configured as the preferred state according to the configuration instruction, the Create a storage space and store the sensor ID in the above storage space. Correspondingly, if the sensor ID needs to be configured from the preferred state to the initial state, delete the sensor ID from the above preferred state table. Wherein, the above-mentioned storage space is a storage location in the page table of the storage list, and the number of sensor identifications contained in any page table is not greater than the threshold number specified in the intelligent platform management interface specification, that is, each page table can store sensor identifications The number is not more than 255.
