Description
Technical Field
The invention relates to the technical field of switches, in particular to a method, a system, a terminal and a storage medium for synchronizing factory information of a switch.
Background
The DMI is a management system that helps collect computer system information, and is mainly used for storing relevant data of the system itself and peripheral devices, where the data includes system configuration information such as CPU, memory, I/O expansion slot, and the like. SMBIOS is a unified specification that a motherboard or system manufacturer needs to follow to display product management information in a standard format. The collection of DMI information must be done with strict compliance with the SMBIOS specification, with the collected data being stored in the SMBIOS table. DMI plays a role of an interface between a management tool and an operating system, establishes a standard manageability system, and facilitates computer manufacturers and users to manage and view relevant information of the system. The FRU is an important facility for recording device configuration information, and generally, devices that are large or small can have their own FRU, such as power supply, fan, BMC, and the like. The ONIE is a small operating system for a bare metal network switch, and mainly provides an automatic configuration environment for installing an image file of an operating system provided by a manufacturer. ONIE has its own FRU, which is stored in EEPROM of ONIE, and it stores important product information provided by manufacturer, and is not easy to lose when power is off. Through the FRU of the ONIE, vendors and users can view asset information, MAC addresses, serial numbers, manufacturers, etc. of switch devices. Usually, when the switch device is shipped from a factory, the information of the corresponding fields of the DMI and the FRU should be kept consistent, i.e. synchronous update of the information of the DMI and the FRU is required. If the two information updates are asynchronous, when the relevant field information of the FRU is changed and a certain device is replaced or updated, the phenomenon that the system configuration information of the DMI and the system configuration information of the FRU are inconsistent occurs, so that the BIOS code needs to be modified again, a new version is published, and the research and development investment is increased.
The existing information synchronization methods are of two types, respectively: the method comprises the steps that information in the DMI is updated through a static character string set in a BIOS source code, the BIOS uses a static character string which is written in advance to construct a DMI table in a starting stage, and when a certain accessory in an exchanger is replaced or updated, synchronous updating of the DMI information is guaranteed through the static character string in an updating code; generally, a scheme of DMI synchronization to BMC FRU is adopted in a server, an IPMI command is sent to BMC to obtain FRU information, and a DMI table is constructed according to the FRU information. The scheme can ensure the synchronous update between the DMI information and the BMC FRU information.
However, updating the DMI information through the static character string is cumbersome and complicated, and once the information of the relevant device of the switch product is changed, the BIOS source code needs to be modified and the version needs to be reissued, which wastes time and labor and delays the development progress of the product. By adopting the scheme of synchronizing the BMC FRU by the DMI, although synchronous updating between the DMI information and the BMC FRU information can be ensured, the switch equipment is not necessarily provided with the BMC, so that the scheme needs to be changed according to the research and development requirements of an actual switch.
