Embodiment Construction

[0016] The embodiment of the present invention provides a method for DMI synchronous FRU, first create DMI Table, read the default value of DMI Table from NVRAM, then send IPMI command to obtain FRU information from BMC, update DMI Table with the field of FRU, overwrite The default value of the DMI Table is dropped, and the FRU information is successfully synchronized from the BMC. After the DMI Table is updated, the contents of the DMI Table will be saved in NVRAM, which is not easy to lose when power off. When the synchronization of FRU information from the BMC fails, the DMI information that was successfully synchronized last time will be read from the NVRAM to update the DMI Table. Therefore, the method for synchronizing the FRU by the DMI is improved, and the consistency of the information between the DMI and the FRU is guaranteed.

[0017] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutio...

Abstract

The invention discloses a method for synchronizing a DMI (desktop management interface) and an FRU (field replace unit). The method includes steps of S10, booting a BIOS (basic input / output system), creating a DMI table, and filling the DMI table with default data of the DMI table; S11, transmitting IPMI (intelligent platform management interface) commands to a BMC (baseboard management controller) via a HOST system to acquire FRU information; S12, updating the DMI table when the FRU information is successfully acquired, storing the DMI table into an NVRAM (nonvolatile random access memory), or reading DMI data stored in the NVRAM previously when the FRU information is not successfully acquired, and updating the DMI table. The method has the advantages that contents of the DMI table can be stored in the NVRAM after the DMI table is completely updated, and are not easy to lose during power failure; DMI information which is previously successfully synchronized can be read from the NVRAM when the DMI and the FRU fail to be synchronized, so that the DMI table can be updated by the aid of the DMI information, and the consistency of the DMI information and the FRU information can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of computer server design, in particular to a method for DMI synchronizing FRUs. Background technique [0002] The main component of DMI (Desktop Management Interface, desktop management interface) is the Management Information Format (MIF) database. This database includes all information about server systems and accessories. Through DMI's MIF database, users can obtain serial number, manufacturer, asset number information and other system accessories information. SMBIOS is a unified specification that motherboard or system manufacturers need to follow to display product management information in a standard format. DMI is a management system that helps collect computer system information. The collection of DMI information must be carried out under the premise of strictly following the SMBIOS specification. SMBIOS and DMI are open technical standards drafted by the industry guidance organization Desktop Ma...
