Description

  The present invention relates to a log management technique in an information processing apparatus.

  The baseboard management controller (BMC) has functions such as power control of a computer system, temperature or voltage monitoring, and system operation monitoring. In recent computer systems, the BMC also performs power control on the system from the remote computer, remote media control, and multitasking of processing executed by the BMC itself. As the functions of BMC are diversified and complicated as described above, the number of cases where BMC itself stalls has increased.

  The BMC can receive a system abnormality log from an operating system (OS), a BIOS (Basic Input / Output System), and the like, and can execute processing such as storage according to the log information. Therefore, when the BMC is stalled, there is a problem that even if the BMC returns from the stall, it is not known whether there is a system abnormality during that time.

  As a technique related to such a problem, Patent Document 1 discloses an information processing apparatus that constantly saves a log stored in a volatile memory in a nonvolatile memory. In the information processing apparatus described in Patent Document 1, the log agent always saves the log temporarily stored in the volatile memory in the OS to the nonvolatile memory of the BMC that operates independently of the OS. To do. With such a mechanism, even when the OS stalls, the log stored in the volatile memory is lost, but the user can use the log saved in the BMC.

  Patent Document 2 discloses a computer system that restores a BMC by BIOS when the BMC stalls. In the computer system described in Patent Document 2, when the exchange of commands with the BMC becomes impossible during the POST (power-on self-test) performed after the computer system is started, the BIOS restarts the BMC. to start. In this way, the computer system solves the problem that the BMC remains in a faulty state when some of the functions of the BMC are disabled to such an extent that power control and WDT (Watch Dog Timer) can be reset. be able to. Here, the WDT is a timer controlled by external hardware (control circuit) that monitors the BMC itself. When the reset operation is not regularly performed, the WDT recovers the monitored BMC by restarting or the like.

  Patent Document 3 discloses a server system that can collect a dump when a BMC is stalled. In the server system described in Patent Document 3, the hardware (HW) monitors the firmware of the BMC by the above-described WDT. When a BMC stall is detected, the HW stores that the stall detection is a reset factor, and further resets the BMC. When the boot loader executed first in starting the BMC recognizes that the reset factor is stall detection, the memory usage area of the OS remaining in the memory is collected as a dump before erasing the memory contents. In this manner, this server system realizes OS dump collection when the BMC is stalled.

  However, in the information processing apparatus disclosed in Patent Document 1, since the logs during the OS stalling cannot be automatically taken into the original recording destination after returning, the logs are processed manually. There is a problem that must be done.

  In addition, in the computer system and the server system disclosed in Patent Documents 2 and 3, nothing is taken into consideration for logs issued by an OS or the like that continues to operate even during a BMC stall.

It is a figure which illustrates composition of a computer (information processor) applicable to each information processor 1 or 100 concerning each embodiment of the present invention, and its modification.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 1 is a block diagram showing the configuration of the information processing apparatus 1 according to the first embodiment of the present invention. Referring to FIG. 1, the information processing apparatus 1 according to the present embodiment includes a control circuit 10, a baseboard management controller (BMC) 20, and a nonvolatile memory 30. The control circuit 10 and the BMC 20 can communicate with each other via a communication path 40 such as a bus. The control circuit 10 and the BMC 20 can read / write information from / to the nonvolatile memory 30 via the communication path 40 or another communication path (not shown).

  The information processing apparatus 1 may be configured by a general information processing apparatus (computer) that operates under the control of a computer program (software program) executed using a CPU (Central Processing Unit: not shown). . Alternatively, each unit of the information processing apparatus 1 may be configured by a dedicated hardware device or a logic circuit. A hardware configuration example in which the information processing apparatus 1 is realized by a computer will be described later with reference to FIG.

  The control circuit 10 includes a log issuing unit 11. The control circuit 10 is a circuit that can operate independently of the BMC 20. The number of control circuits 10 in this embodiment is an example. In the information processing apparatus 1, a plurality of control circuits 10 may be included.

  The log issuing unit 11 can request registration of log information to the BMC 20 via the communication path 40. The log issuing unit 11 stores the save log information 31 including the log information in the nonvolatile memory 30 when the registration of the log information to the BMC 20 fails. The log issuing unit 11 may include, in addition to the log information, additional information such as the generation time of the log information and the issuer of the log information in the saved log information 31. For example, the log information can include information related to the occurrence of a system abnormality.

  The BMC 20 includes a nonvolatile memory check unit 21 and a log processing unit 22.

  The nonvolatile memory check unit 21 confirms whether the save log information 31 is stored in the nonvolatile memory 30 when the BMC 20 is activated. The non-volatile memory check unit 21 takes over the processing to the log processing unit 22 when the save log information 31 is stored in the non-volatile memory 30.

  The log processing unit 22 reads the save log information 31 when the save log information 31 is stored in the nonvolatile memory 30. Then, the log processing unit 22 executes predetermined processing on the log information based on the read save log information 31. The log processing unit 22 deletes the save log information 31 from the nonvolatile memory 30.

  The nonvolatile memory 30 is realized by, for example, a semiconductor memory device such as a flash memory or a disk device. The nonvolatile memory 30 can store save log information 31.

  Next, the operation of the present embodiment having the above-described configuration will be described in detail. As an example, an operation of the information processing apparatus 1 will be described in which the control circuit 10 registers log information related to a system abnormality in the BMC 20 when a system abnormality occurs.

  When the log issuing unit 11 of the control circuit 10 tries to register the log information related to the system abnormality in the BMC 20, if the BMC 20 is stalled, the log issuing unit 11 saves the log information instead of the BMC 20. The log information 31 is stored in the nonvolatile memory 30. When the BMC 20 recovers from the stall by restarting, the nonvolatile memory check unit 21 of the BMC 20 registers the log information during the stall depending on the presence / absence of the saved log information 31 read from the nonvolatile memory 30. Check to see if That is, if the save log information 31 is stored in the nonvolatile memory 30, the nonvolatile memory check unit 21 can determine that there is a system abnormality during the stall. Further, when the save log information 31 is not stored in the nonvolatile memory 30, the nonvolatile memory check unit 21 can determine that there is no system abnormality during the stall.

  When the save log information 31 is stored in the non-volatile memory 30, the log processing unit 22 further obtains log information related to the system abnormality that occurred during the stall from the saved log information 31. Then, the log processing unit 22 can perform predetermined processing on the log information.

  As a method of restarting when the BMC 20 is stalled, a well-known general technique such as the above-described WDT and Patent Document 3 in the “Background Art” column can be adopted. The detailed description in is omitted.

  As described above, according to the present embodiment, when the BMC 20 returns from a stall, the information processing apparatus 1 and the like that can acquire log information generated while the BMC 20 was stalled without human intervention is provided. There is an effect that can be done. As a result, there is an effect that it is possible to know whether there is a system abnormality while the BMC 20 is stalled.

  The reason is that the log issuing unit 11 of the control circuit 10 does not register the log information regarding the system abnormality or the like that occurred while the registration of the log information with respect to the BMC 20 is failed in the nonvolatile memory 30 instead of registering in the BMC 20. It is because it preserves. In addition, when the BMC 20 is activated, the nonvolatile memory check unit 21 of the BMC 20 can determine whether there is a system abnormality depending on whether the save log information 31 is stored in the nonvolatile memory 30. This is because the log processing unit 22 can automatically acquire log information generated during the stall from the save log information 31 stored in the nonvolatile memory 30.

  In addition, the following can be considered as a modification of this embodiment.

  For example, the configuration of the nonvolatile memory 30 shown in the present embodiment is an example. The nonvolatile memory 30 may be included in either the control circuit 10 or the BMC 20 as long as it can be accessed from the control circuit 10 and the BMC 20.

  Further, the deletion of the save log information 31 performed by the log processing unit 22 of the BMC 20 may be executed by a functional unit other than the log processing unit 22 as part of the system initialization process performed in addition to the above-described operation. .

<Second Embodiment>
Next, a second embodiment based on the above-described first embodiment will be described. In the following, the characteristic part according to the second embodiment will be mainly described, and the components of the second embodiment having the same configuration as the first embodiment are attached in the first embodiment. The same reference numerals as those of the reference numerals are attached, and the detailed description of the constituent elements is omitted.

  The present embodiment is a specific example showing a system configuration including a plurality of control circuits 10 (log issuing units 11) in the first embodiment.

  First, the configuration of this embodiment will be described below with reference to FIG. FIG. 2 is a block diagram showing the configuration of the information processing apparatus 100 according to the second embodiment of the present invention. Referring to FIG. 2, the information processing apparatus 100 according to the present embodiment includes a BIOS (Basic Input / Output System) 110, a CPU 120, a BMC 200, and a nonvolatile memory 30. The BIOS 110, the CPU 120, and the BMC 200 can communicate with each other via the bus 300. The BIOS 110, the CPU 120, and the BMC 200 can read / write information from / to the nonvolatile memory 30 via the bus 300.

  The information processing apparatus 100 may be configured by a general information processing apparatus (computer) that operates under the control of a computer program (software program) executed using the CPU 120. Alternatively, each unit of the information processing apparatus 100 may be configured by a dedicated hardware device or a logic circuit. A hardware configuration example in which the information processing apparatus 100 is realized by a computer will be described later with reference to FIG.

  The BIOS 110 includes a log issuing unit 111. The CPU 120 includes an OS (operating system) 121. The BIOS 110 and the OS 121 are programs executed by the CPU 120. The OS 121 includes a log issuing unit 122. The BIOS 110 and the OS 121 (CPU 120) are based on the control circuit 10 in the first embodiment.

  The log issuing units 111 and 122 are based on the log issuing unit 11 in the first embodiment. The log issuing units 111 and 122 in this embodiment can issue a registration request for requesting registration of log information to the BMC 200 via the bus 300. The registration request includes log information. When the log information registration to the BMC 200 fails, the log issuing units 111 and 122 store the save log information 31 including the log information in the nonvolatile memory 30. In the present embodiment, when a system abnormality occurs while the OS 121 is operating, the log issuing unit 122 issues a log information registration request regarding the system abnormality. When the OS 121 cannot operate or a system abnormality occurs before the OS 121 operates, the log issuing unit 111 issues a log information registration request regarding the system abnormality. The configurations, functions, and contents of the log issuing units 111 and 122, the log information, and the save log information 31 are the same as those in the first embodiment except for the points described above, and thus a detailed description thereof is omitted.

  The BMC 200 includes a nonvolatile memory check unit 21, a log processing unit 222, and a storage device 223. The storage device 223 can store log information 224. The BMC 200 is based on the BMC 20 in the first embodiment. The BMC 200 is a circuit that can operate independently of the BIOS 110 and the CPU 120.

  The nonvolatile memory check unit 21 is based on the nonvolatile memory check unit 21 in the first embodiment. When the save log information 31 is stored in the nonvolatile memory 30 when the BMC 200 is activated, the nonvolatile memory check unit 21 takes over the processing to the log processing unit 222. Since the configuration and function of the nonvolatile memory check unit 21 are the same as those in the first embodiment, a detailed description thereof is omitted.

  The log processing unit 222 is based on the log processing unit 22 in the first embodiment. The log processing unit 222 according to the present embodiment can execute a predetermined process based on the log information registration request received from the log issuing units 111 and 122. In addition, when the log processing unit 222 takes over the processing from the nonvolatile memory check unit 21, the log processing unit 222 logs the log information included in the save log information 31 stored in the nonvolatile memory 30 from the log issuing unit 111 or 122. The same processing as when receiving an information registration request is executed. In the present embodiment, the log processing unit 222 can store log information included in the log information registration request or the saved log information 31 as log information 224 in the storage device 223 as at least predetermined processing. Since the configuration and functions of the log processing unit 222 are the same as those in the first embodiment except for the points described above, a detailed description thereof is omitted.

  The storage device 223 is realized by, for example, a semiconductor memory device or a disk device.

  The nonvolatile memory 30 is based on the nonvolatile memory 30 in the first embodiment. The nonvolatile memory 30 is realized by, for example, a semiconductor memory device such as a flash memory or a disk device. The nonvolatile memory 30 can store save log information 31 output from the log issuing unit 111 or the log issuing unit 122.

  Next, the operation of the present embodiment having the above-described configuration will be described in detail. First, with reference to FIG. 3, an operation related to registration of log information performed by the log issuing units 111 and 122 will be described. FIG. 3 is a flowchart showing an operation related to registration of log information performed by the log issuing units 111 and 122 in the second embodiment. Hereinafter, the log information registration operation of the log issuing unit 122 when a system abnormality occurs will be described as a specific example. That is, in the following specific example, the OS 121 is operating.

  First, when a system abnormality occurs during the operation of the OS 121, the log issuing unit 122 generates log information (step S10). Specifically, the log issuing unit 122 acquires information indicating what kind of abnormality has occurred from the CPU 120 or a chip set (not shown) via the OS 121, and generates log information based on the information. To do.

  Next, the log issuing unit 122 requests the BMC 200 to register log information (step S11). Specifically, the log issuing unit 122 may issue to the BMC 200 a log registration command using log information based on IPMI (Intelligent Platform Interface Specification) specifications as an argument. The IPMI specification is a standard interface standard for monitoring and operating the hardware state via a network.

  When the log information registration is successful (YES in step S12), the log issuing unit 122 ends the log information registration operation corresponding to the occurrence of the system abnormality. Specifically, when the BMC 200 is operating normally, the log processing unit 222 of the BMC 200 stores at least the log information included in the log information registration request received from the log issuing unit 122 as the log information 224. Save to 223. The log processing unit 222 may further perform various processes such as notifying that a log information registration request has been received from the OS 121 by a predetermined method. The log issuing unit 122 may recognize that the registration of the log information has been successful, for example, by successfully transmitting the log registration command.

  On the other hand, when the registration of the log information has failed (NO in step S12), the log issuing unit 122 stores the save log information 31 including the log information in the nonvolatile memory 30 (step S13). Specifically, for example, when the BMC 200 is stalled, the log issuing unit 122 recognizes that the registration of the log information has failed because the log registration command has failed due to a communication error with the BMC 200. May be. In this case, the log issuing unit 122 generates save log information 31 including log information. The log issuing unit 122 stores the generated save log information 31 in the nonvolatile memory 30. Thereafter, the log issuing unit 122 ends the log information registration operation corresponding to the occurrence of the system abnormality.

  The above is the log information registration operation of the log issuing unit 122 when a system abnormality occurs. When the OS 121 cannot operate or a system abnormality occurs before the OS 121 starts operation, the log issuing unit 111 of the BIOS 110 performs the same processing as the log issuing unit 122 described above. As a method for the BIOS 110 to recognize that the OS 121 cannot operate, a general technique such as WDT described in the “Background Technology” column can be adopted, and thus detailed description in this embodiment is omitted.

  Next, with reference to FIG. 4, the operation at the time of starting the BMC 200 will be described. FIG. 4 is a flowchart illustrating operations performed by each unit of the BMC 200 when the BMC 200 is activated in the second embodiment. In the following, a specific example of the operation when the stalled BMC 200 is restarted after the log information registration operation performed by the log issuing unit 122 when the above-described system abnormality occurs will be described. As the method for restarting the stalled BMC 200, various general techniques can be adopted as described above in the “Background Art” column, and thus detailed description in this embodiment will be omitted.

  When the stalled BMC 200 is restarted, the non-volatile memory check unit 21 of the BMC 200 checks the presence / absence of the save log information 31 in the non-volatile memory 30 (step S20).

  When the save log information 31 is stored in the non-volatile memory 30 (YES in step S21), the non-volatile memory check unit 21 takes over the process to the log processing unit 222. Then, the log processing unit 222 reads the save log information 31 from the nonvolatile memory 30 (step S22).

  The log processing unit 222 executes a predetermined process for the log information based on the read save log information 31 (step S23). Specifically, the operation of the log processing unit 222 when the BMC 200 is operating normally as described above in the description of the operation of YES in step S12 is performed. That is, the log processing unit 222 performs predetermined processing such as saving the log information included in the save log information 31 as the log information 224 in the storage device 223. Note that the log processing unit 222 may perform processing different from the processing for the log information registration request from the log issuing unit 111 or 122 when the saved log information 31 is stored.

  Finally, the log processing unit 222 deletes the save log information 31 from the nonvolatile memory 30 (Step S24).

  In this way, when the BMC 200 returns from a stall, the log processing unit 222 can acquire log information related to a system abnormality that occurred while the BMC 200 was stalled without human intervention. As a result, the information processing apparatus 100 has an effect of knowing whether there is a system abnormality while the BMC 200 is stalled.

  The above is the operation when the stalled BMC 200 is restarted. In the case of starting (restarting) the normal information processing apparatus 100 in which the BMC 200 is not stalled, the evacuation log information 31 is not stored in the nonvolatile memory 30 (NO in step S21). In step 21, the process may be terminated as it is.

  As described above, in the present embodiment, as in the first embodiment described above, when the BMC 200 returns from a stall, log information generated during the stall is acquired without human intervention. There is an effect that there is an effect that it is possible to provide the information processing apparatus 100 and the like.
