Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a sensor management method and apparatus.
Background
Inside the server, the BMC (Baseboard Management Controller) is configured to generate a data record according to the status information of each component reported by the sensor, and manage the data record.
In the intelligent management architecture of the server, the sensor is the minimum unit for managing the state information of each component in the server by the BMC. With the increasing power of the server, the number of components in the server is increasing, so that the number of sensors that the BMC needs to manage is increasing. However, in the IPMI (Intelligent Platform management interface) 2.0 specification, the valid range of the sensor number that a user can access to one BMC is 0 to 254, so that the number of sensors that one BMC can control is limited to a threshold number (i.e., 255).
At present, when the number of sensors under the jurisdiction of a BMC exceeds a threshold number, a method of reducing the number of sensors is generally adopted to solve the problem that the number of sensors under the jurisdiction of the BMC has an upper limit value. For example, the number of sensors is reduced by deleting unnecessary sensors, and by adopting the technical scheme, the problem that component state information reported by a specific sensor cannot be acquired exists. In addition, the number of sensors can be reduced by combining a plurality of sensors into one sensor, for example, the sensors a to H respectively monitor the states of eight memories, that is, one sensor monitors the state of one memory, and when any memory fails, the sensor corresponding to the any memory sends a failure warning to the BMC; at this time, the eight sensors are combined into one sensor, the state of the eight memories is monitored by using the sensor a, and if any one of the eight memories fails, the sensor a sends a failure warning to the BMC. By adopting the technical scheme, one sensor manages a plurality of memories, and the sensor management granularity is large, so that the BMC cannot accurately position the failed memory according to the fault warning sent by the sensor.
Therefore, in the prior art, the sensor management granularity is large, and the BMC cannot accurately position the memory with faults according to the fault warning sent by the sensor.

Detailed Description
The problem of inaccurate fault location exists in the management process of each sensor in the server is solved. In the embodiment of the invention, the storage list of each state in the BMC stores the sensor identifier of the corresponding state, and when a user accesses the sensor identifier stored in the BMC, if the state corresponding to the accessed sensor identifier is an activated state, the page table containing the accessed sensor identifier is switched from the activated state to the preferred state. By adopting the technical scheme of the invention, the sensors are classified according to the corresponding states of the sensors, so that the sensor identifications in different states are stored in different storage lists, and each page table in the storage lists can store the number of the sensor identifications as a threshold value, so that the corresponding sensors can be configured for each component to be monitored, the number of the sensors governed by the BMC is not required to be limited, the management granularity of the sensors is ensured, and the fault positioning precision is effectively improved.
Fig. 1 is a system architecture diagram in an embodiment of the present invention, where a BMC is located in a server, and establishes a connection with the server through a hardware interface, and generates a data record according to a state of a component to be monitored, which is reported by each sensor in the server, and a database in the BMC is used to store the data record. Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, in the embodiment of the present invention, a detailed process for managing sensors includes:
step 200: and receiving an access instruction, and searching a state corresponding to the sensor identifier from a locally stored storage list according to the sensor identifier carried in the access instruction.
In the embodiment of the invention, after the BMC is powered on and started, a corresponding state is configured for each sensor under local jurisdiction, namely, the state corresponding to the sensor is configured to be an initial state (Inactive), or the state corresponding to the sensor is configured to be an Active state (Active), or the state corresponding to the sensor is configured to be a Selected state (Selected). When the BMC is started, the states corresponding to all sensors locally administered by the BMC are initial states, and when the states corresponding to the sensors are initial states, the BMC does not scan the sensors, the initial sensors do not generate event records, and a user cannot access the sensor values corresponding to the initial sensors; when the BMC configures the state corresponding to the locally administered sensor into the activated state, the BMC continuously scans the activated state sensor to acquire an event record generated by the activated state sensor, but a user cannot access the sensor value corresponding to the activated state sensor; when the state corresponding to the sensor under the local jurisdiction is configured to be the preferred state, the BMC continuously scans the sensor in the preferred state to acquire an event record generated by the sensor in the preferred state, and a user can access the sensor value corresponding to the sensor in the preferred state. In the process, the event record corresponding to the sensor is the state information corresponding to the monitored component, such as fault warning information, hot plug event information and the like; the sensor value corresponding to the sensor is a reading recorded by the sensor, such as a temperature value recorded by the temperature sensor.
Optionally, the method for the BMC to configure the corresponding state for each locally administered sensor respectively includes: respectively configuring corresponding states for each sensor under local administration according to a preset configuration strategy stored locally; or receiving a configuration instruction input by a user, acquiring configuration information carried in the configuration instruction, and configuring corresponding states for each sensor in local administration according to the configuration information, wherein the user can send the configuration instruction to the server through the configuration instruction input by the terminal, and the user can input the configuration instruction through an operation interface corresponding to the server.
By adopting the technical scheme, the corresponding state of the sensor is configured and adjusted according to the local preset configuration strategy of the BMC or the instruction input by the user, so that the flexibility of managing the server through the BMC is improved; and according to the user requirements, unnecessary sensors are not scanned, unnecessary expenses of the system are reduced, and the working efficiency of the system is improved.
Optionally, three storage lists, namely an initial state table, an activated state table, and a preferred state table, are stored in the BMC, and the sensor identifiers of the corresponding states are stored in different storage lists. When the state corresponding to the sensor is an initial state, storing the sensor identification into an initial state table stored locally; when the state corresponding to the sensor is the activated state, storing the sensor identification into an activated state table stored locally; and when the state corresponding to the sensor is the initial state, storing the sensor identification into an activated state table stored locally.
Step 210: and when the state corresponding to the sensor identifier is an activated state, switching the page table containing the sensor identifier in the storage list to a preferred state.
In the embodiment of the 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 of the sensor identifier accessed by the user is switched from the activated state to the preferred state. The number of the sensor identifications contained in any page table in the storage list is not more than the threshold number specified by the intelligent platform management interface specification, namely, the number of the sensor identifications contained in any page table is not more than 255.
Optionally, referring to fig. 3, which is a schematic diagram of a storage list in an embodiment of the present invention, in the storage list, an initial state table includes a plurality of page tables, each page table may store less than or equal to 255 sensor identifiers, an upper limit value of the sensor identifiers that can be stored in the initial state table is n × 255, where n is the number of page tables included in the initial state table; the activated state table includes a plurality of page tables, each page table can store less than or equal to 255 sensor identifiers, and the upper limit value of the sensor identifiers which can be stored in the activated state table in the activated state is n × 255, where n is the number of page tables included in the activated state table; specifically, the preferred state table includes a page table, and the page table can store less than or equal to 255 sensor identifiers, and the upper limit value of the sensor identifier that can be stored in the preferred state table is 255, so that the upper limit value of the number of user-accessible sensors in a BMC-governed sensor that meets the IPMI2.0 specification is 255. Each page table in the storage list corresponds to a page table number; the sensor identifier stored in each page table may be a related sensor identifier, for example, the sensor function corresponding to the sensor identifier stored in the same page table is the same; the sensor id stored in each page table may also be an unrelated sensor id.
By adopting the technical scheme, the sensor identifications in different states are stored in different storage lists, namely the sensor identifications in different states are managed through different storage lists, each storage list can manage at least 255 sensors, and the number of the sensors which can be managed by the three storage lists is far greater than the threshold number of the sensors which can be managed by one BMC and is regulated by IPMI2.0 specification, so that the bottleneck problem that the BMC can manage the number of the sensors is avoided; and the sensor identifications in different states are stored in different storage lists, so that the management work of the sensor is more convenient. The technical scheme of the invention can be applied to RAS (Reliability, Availability and Serviceability) application scenes and large-scale server application scenes.
Step 220: outputting a page table containing the sensor identification.
In the embodiment of the present invention, the BMC outputs the obtained page table including the sensor identifier to a terminal, or outputs the obtained page table including the sensor identifier to an operation interface of a server.
Further, because the BMC scans only the sensor whose attribute is in the activated state or the preferred state, the BMC obtains the event record corresponding to the sensor identifier in the activated state or the preferred state, and the sensor identifier; and binding the sensor identifier and the event record corresponding to the sensor identifier, and storing the bound sensor identifier and the event record corresponding to the sensor identifier as a data record in a local database.
In the embodiment of the invention, the number of the sensors managed by one BMC is far more than 255, and the storage lists stored by the sensor identifiers in different states are different. Therefore, if the sensor serial number is only used as the sensor identifier for storage in the prior art, the sensor serial numbers in different storage lists may be the same, which may cause a problem of repeated sensor identifiers. Therefore, optionally, after the sensor identifier is stored in the corresponding storage list, the sensor identifier is updated, that is, the storage list identifier corresponding to the sensor identifier and the sensor serial number are added to the sensor identifier; the storage list identification comprises a state corresponding to the storage list and a page table number where the sensor identification is located. For example, if the sensor number included in the sensor identifier is 36 and the stored list identifier is the page table 17 in the active state table, then the identifier indicating the sensor 36 is stored in the page table 17 in the active state table. Optionally, four bytes are used to store the sensor identifier.
Further, in the BMC, when a user needs to acquire a data record, the user can query the data record through an IPMI instruction on a UI interface of the BMC. Specifically, when the BMC receives a data record query instruction input by a user, acquiring an identifier of an event record carried in the data record query instruction, and acquiring a data record corresponding to the identifier of the event record stored in the BMC local database according to the identifier of the event record, where the identifier of the event record includes a time attribute corresponding to the event record and a type attribute of the event record (such as a fault alarm event, a hot plug event, a sensor output value exceeding a threshold event, and the like); or acquiring a sensor identifier carried in the data record query instruction, and acquiring a data record corresponding to the sensor identifier stored in the BMC local database according to the sensor identifier, wherein the sensor identifier is a sensor serial number and a storage list identifier corresponding to the sensor identifier. Optionally, when a user queries a data record through an IPMI instruction, the IPMI instruction is a data record Query instruction in an SQL (structured Query Language), and the BMC analyzes the data record Query instruction in the SQL format to obtain an identifier of an event record or a sensor identifier carried in the data record Query instruction in the SQL format.
By adopting the technical scheme, the sensor identification and the event record in the storage list are bound, and the generated data record is stored in the database of the BMC, so that the problem of data record confusion caused by asynchronism between the storage list and the event record is avoided, the synchronism of the sensor identification and the event record in the storage list in the BMC is ensured, and the accuracy of the data record generated based on the storage list and the event record is improved.
Based on the BMC, when a user needs to manage the data records in the storage list, an IPMI instruction is sent to the BMC to manage the data records in the storage list. Specifically, when a data record management instruction input by a user is received, a sensor identifier carried in the data record management instruction is acquired by the BMC; and adjusting the data record corresponding to the sensor identifier according to the data record management information carried in the data record management command.
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 data record corresponding thereto.
The process of adjusting the data record corresponding to the sensor identifier by the BMC specifically includes: when the data record management information is data record deleting information, deleting data records corresponding to sensor identifications stored in a database, and deleting the sensor identifications in a storage list, namely releasing storage space occupied by the data records consisting of the sensor identifications and event records; when the data record management information is data record adding information, acquiring a sensor identifier to be added, adding the sensor identifier to be added into a preferred state table or an activated state table, namely creating a storage space in the preferred state table or the activated state table, and updating the sensor identifier according to the storage space identifier (namely a storage list identifier) after adding the sensor identifier to be added into the created storage space; and when the data record management information is the state corresponding to the changed sensor identifier, acquiring the sensor identifier to be changed and the state change information, storing the sensor identifier to be changed into a corresponding storage list according to the state change information, and updating the data record corresponding to the sensor identifier to be changed.
Optionally, changing the state corresponding to the sensor identifier is to change the state corresponding to the sensor identifier from the preferred state to the activated state; or changing the state corresponding to the sensor identifier from the activated state to the preferred state.
Referring to fig. 4, the process of recording the sensor identifier to be changed and the corresponding data thereof according to the state change information specifically includes:
in the first case: and if the state change information is that the state corresponding to the sensor identifier is changed from the preferred state to the activated state, switching the storage list corresponding to the sensor identifier from the preferred state to the activated state, and updating the sensor identifier and the data record corresponding to the sensor stored in the database.
In the second case: and if the state change information is that the state corresponding to the sensor identifier is changed from the activated state to the preferred state, switching the storage list corresponding to the sensor identifier from the activated state to the preferred state, updating the sensor identifier and the data record corresponding to the sensor identifier stored in the database.
By adopting the technical scheme, the sensor identifications in different states are stored in different storage lists, so that a user can adjust the state corresponding to the sensor identification in the storage list through an IPMI instruction and adjust the data record in the database, thereby effectively improving the flexibility of data record management.
Based on the above technical solution, referring to fig. 5, in the embodiment of the present invention, a process of accessing a sensor identifier by a user through an IPMI instruction is as follows:
step 500: the BMC receives a first IPMI instruction input by a user and acquires a storage list identifier carried in the IPMI instruction.
In the embodiment of the present invention, the IPMI command may be an OEM (Original Equipment Manufacturer) command, that is, an IPMI command with a custom format. For example, if it is required to access page table 0 of the active state table, the BMC receives a first IPMI instruction (set sensor page id = 0) input by the user.
Step 510: and the BMC configures the page table corresponding to the storage list identifier into a 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 a preferred state, that is, switches to the page table interface corresponding to the storage list identifier. For example, after receiving a first IPMI command (setsensor page id = 0) input by the user through the terminal, the BMC switches to the page table 0 and sends a configuration success command (set sensor page id =0 ok) to the terminal.
Step 520: and the BMC receives a second IPMI command sent by the user and acquires the sensor serial number carried in the second IPMI command.
In this embodiment of the present invention, if it is required to access the sensor 20 in the page table 0 in the active state storage list, the BMC receives a second IPMI instruction (get sdr sensornum = 0) sent by the user through the terminal.
Step 530: and the BMC calls the sensor serial number from the preferred state table and sends the sensor serial number to a calling success instruction by the terminal.
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 invokes the sensor 20 in the page table 0 of the active state table, and sends an invocation success instruction (sdr sensum = 0) to the terminal. The user can change the state corresponding to the sensor identifier through the sensor identifier presented by the terminal.
In the embodiment of the present invention, the user may send the first IPMI instruction and the second IPMI instruction to the BMC to access the sensor identifier, and optionally, the user may also send only one IPMI instruction to the BMC, where the IPMI instruction includes the storage list identifier and the sensor serial number.
Based on the above technical solution, referring to fig. 6, in the embodiment of the present invention, a process of a user obtaining a data record through an IPMI instruction is as follows:
step 600: the BMC receives a data record query instruction input by a user through a terminal, and acquires an event record identifier carried in the data record query instruction.
In an embodiment of the present invention, the data record query command is an IPMI command. For example, the data record query instruction may be in the form of: get sel info (sel id = XX), where sel represents the time record and sel id identifies the identity of the event record.
Step 610: and the BMC calls the data record corresponding to the identifier of the event record from the database through the identifier of the event record.
Step 620: and the BMC sends the data record to a terminal.
In the embodiment of the present invention, after acquiring the data record corresponding to the identifier of the event record, the BMC 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, a process of configuring, by the BMC, the sensor in the initial state according to a configuration instruction input by a user is as follows:
step 700: and receiving a configuration instruction, and acquiring the sensor identifier with the initial state and the configured state carried in the configuration instruction.
In the embodiment of the invention, the configured states comprise an activated state and a preferred state.
Step 710: when the configured state is a preferred state, storing the sensor identifier into a page table of a preferred state table; and when the configured state is a preferred state, storing the sensor identification into a page table of the activated state table.
