Description
Technical Field

Background
With the continuous improvement of the operation performance of high-performance computers, the number of nodes included in the host system increases dramatically, and thus the scale of the distributed maintenance system taking the maintenance node as a main task also increases. An extremely large number of Baseboard Management Controllers (BMCs) are currently deployed in tightly coupled high-performance computing systems, and their reliability is particularly important as an important component of maintaining the system.
The core component of the BMC is an embedded system, the BMC usually stores own operating system files in a high-capacity Flash, and due to the characteristics of the Flash, bad blocks and failures with certain probability exist, which can cause failure in booting the BMC system. At present, an improved method is to use two-level storage, store bootloader in Nor Flash with better reliability but higher unit price and smaller capacity, store a kernel and a file system in eMMC nand Flash with poorer reliability but larger capacity, and perform offline re-burning when the eMMC nand Flash has a bad block to cause the kernel or the file system to fail. However, this method is inefficient to implement in large-scale systems, resulting in longer mean time to failure recovery and a consequent reduction in reliability and availability to maintain the system.
The invention patent application with application publication number CN103246583A and application publication date 2013, 8 month and 14 days discloses an electronic device with a CPU BIOS repairing function and a repairing method. The electronic device comprises a connection port used for electrically connecting the CPU system with an external device, and when a boot module of the CPU detects that the BIOS version of the boot module is wrong, the boot module copies the stored CPU BIOS from the external device to the flash memory by sending an instruction to the external device electrically connected with the CPU. Therefore, when the BIOS in the flash memory cannot be normally loaded, the CPU can load the BIOS in the external device connected with the electronic device. The method mainly aims at BIOS updating, and the BIOS file is characterized in that the occupied space is small, so that a plurality of external devices can be locally stored. The method mainly solves the problem of repairing the kernel and root file systems, and is characterized by occupying a large space and not being suitable for the limited storage space of a local embedded system. In addition, in the method, the whole processes of BIOS version detection, version search, update and the like are all initiated by the CPU system to be repaired, so that the requirement on the CPU system to be repaired is high, the CPU starting firmware is complex, and the method is not suitable for repairing the embedded system with simpler functions compared with the common CPU system.

Detailed Description
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Unless otherwise defined, all terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that the conventional terms should be interpreted as having a meaning that is consistent with their meaning in the relevant art and this disclosure. The present disclosure is to be considered as an example of the invention and is not intended to limit the invention to the particular embodiments.
Example one
A system for automatically repairing a BMC (baseboard management controller) of a tightly coupled high-performance computer system is suitable for a computer system including a BMC (baseboard management controller), for example, a high-performance computer system with a large number of nodes in a host system. The high-performance computer system deploys a very large number of BMCs (baseboard management controllers) as a distributed maintenance system to maintain the nodes in the high-performance computer system.
The automatic BMC system repair system for a high-performance computer system according to this embodiment includes a management system, a network file system, and a BMC deployed in the high-performance computer system. The BMC usually stores the operating system file in a memory thereof, such as a large-capacity Flash, and because the Flash has bad blocks and failures with a certain probability, the BMC system is likely to fail to boot. Therefore, the BMC in this embodiment stores a BMC boot file (including a BMC kernel and a BMC root file system) required for BMC boot in a two-level storage manner, where the memory includes two different types of storage modules: the first memory module has a higher reliability and a higher price per unit, and the second memory module has a lower reliability and a correspondingly lower price per unit. For example, the first storage module may be implemented by Nor Flash, and the second storage module may be implemented by eMMcnand Flash. The boot loader (Bootloader) of the BMC is stored in a first storage module, and the BMC Kernel (Kernel) and the BMC root file system (Rootfs) are stored in a second storage module. Under normal conditions, the BMC runs a boot loader after being started at power-on, the boot loader loads the BMC kernel from the second storage module to the memory of the BMC, and the boot loader transmits the BMC kernel starting parameters to the BMC kernel. The starting parameters comprise a local path of the BMC kernel in the BMC and a local path of the BMC root file system in the BMC. Therefore, some initialization scripts and services of the BMC root file system in the second storage module are loaded into the memory of the BMC to run, and the start of the BMC is completed. When a second storage module of the BMC is a bad block or fails, failure of the BMC to boot the loader to load the BMC boot file after power-on boot may cause system crash and failure of the BMC boot.
And the network file system stores BMC starting files required by starting each BMC in the computer system. Each BMC in the computer system may access a file on the network file system over a network (e.g., ethernet) as a local file to obtain a BMC boot file required for its boot. The management system can allocate an IP address to each BMC of the computer system, so that the BMC can establish network connection with the network file system, thereby accessing the network file system.
And the management system is used for monitoring the starting state of each BMC of the computer and commanding the BMC to enter an automatic repair mode when the BMC system starting failure is monitored. The management system of this embodiment has a serial port monitoring program in operation under operating condition, and this serial port monitoring program can monitor the serial port output signal of each BMC in the computer system through the port of management system with each BMC serial port communication in the computer system, judges the start state of BMC according to the serial port output signal of BMC to realize the function of monitoring each BMC start state.
When the management system monitors that one or more BMCs fail to start through the serial port, a reset command (rst) is sent to the one or more BMCs which fail to start. After the BMC is reset again, the management system controls the BMC to start and automatically repair the network through the serial port. The BMC runs the boot loader after being powered on and started, establishes Ethernet communication with the network file service system through the IP address allocated by the BMC through the management system, and allocates the IP address to the BMC so that the BMC can access the BMC start file stored in the network file system. And a boot loader of the BMC loads the BMC kernel from the network file system to the memory of the BMC, and transmits the BMC kernel starting parameter to the BMC kernel. The starting parameters comprise IP address information of the BMC, a network path of a BMC kernel and a network path of a BMC root file system. And loading some initialization scripts and services of a BMC root file system in the network file system into a memory of the BMC to run so as to finish the starting of the BMC.
In another embodiment, after the system is successfully started by loading the BMC boot file in the network file system, the BMC further rewrites the downloaded BMC boot file into the second storage module to complete system repair.
Example two
The method is suitable for a computer system comprising BMC, for example, a high-performance computer system with a large number of nodes in a host system. The high-performance computer system deploys a very large number of BMCs (baseboard management controllers) as a distributed maintenance system to maintain the nodes in the high-performance computer system.
In the method of this embodiment, when monitoring that the BMC of each node fails to start, the management system controls the management system to acquire a BMC start file required for starting from the network file service system and loads the BMC start file into a memory of the management system to operate. The method specifically comprises the following steps:
step S1, monitoring the boot status of each BMC in the computer system and instructing the BMC to enter an automatic repair mode when a failure of boot of the BMC is detected. In this step, the management system described in the first embodiment is used to monitor the serial output signal of each BMC in the computer system to monitor the start state of each BMC. When the BMC starting failure is monitored, the management system sends a reset command to the BMC with the starting failure, and then the BMC with the starting failure gradually finishes the loading and repairing of the network file system under the control of the management system.
Step S2, the BMC acquires a BMC boot file required for booting from the network file service system in the automatic repair mode and loads the BMC boot file into its memory for running. Specifically, the BMC runs a boot loader after being started up, the management system allocates an IP address to the BMC, the management system establishes Ethernet communication with the network file service system, and the management system allocates the IP address to the BMC so that the BMC can access a BMC start file stored in the network file system. The BMC boot file refers to a file necessary for booting the BMC system, for example, the BMC boot file of this embodiment includes a BMC kernel and a BMC root file system. And a boot loader of the BMC loads the BMC kernel from the network file system to the memory of the BMC, and transmits the BMC kernel starting parameter to the BMC kernel. The starting parameters comprise IP address information of the BMC, a network path of a BMC kernel and a network path of a BMC root file system. And loading some initialization scripts and services of a BMC root file system in the network file system into a memory of the BMC to run so as to finish the starting of the BMC.
And step S3, the BMC stores the BMC starting file. After the restart is successful in step S2, the BMC rewrites the BMC boot file downloaded from the network file system in step S2 into the second storage module. And updating the BMC start file stored in the local BMC by using the BMC start file acquired from the network file system, so that the BMC can be normally started based on the locally updated BMC start file.
Although embodiments of the present invention have been described, various changes or modifications may be made by one of ordinary skill in the art within the scope of the appended claims.
