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
The present invention relates to computer server design field, be specifically related to the method for the synchronous FRU of a kind of DMI.
Background technology
DMI(Desktop Management Interface, Desktop Management Interface) chief component be Management Information Format(MIF) database.This database includes the information of all concerned server systems and accessory.By the MIF database of DMI, user can obtain sequence number, manufacturer, assets information and other system accessories information.SMBIOS is that mainboard or system manufacturer show the unified standard followed needed for management of product information in a standard format.DMI is the management system helping to collect computer system information, and the collection of DMI information must be carried out under the prerequisite of adhere rigidly to SMBIOS specification.SMBIOS and DMI is by industry Steering Body Desktop Management Task Force(DMTF) technical standard of opening drafted, wherein, DMI design is applicable to any platform and operating system.DMI act as the role of the interface of management tool and system layer.The ALARA Principle system that it establishes standard is more convenient for computer vendors and user to the understanding of system.Computer system management and maintainer can carry out unified management easily by information such as the sequence number of system in DMI, manufacturer, assets number to system.
FRU(Field Replace Unit Field Replaceable Unit) be used to register system configuration another important indicator, server system is divided into multiple FRU equipment, large to power supply, little of equipment such as fan, for server system, FRU information is kept at mainboard BMC(Baseboard Management Controller, baseboard management controller) EEPROM in, power down is not volatile.By BMC, user can check the configuration information of server system outside remote band, is conveniently easy to management.
DMI information is present in server HOST main system, and FRU is kept in server B MC system, for the ease of system management, can by the configuration information in DMI and FRU synchronizing information, and both just can be consistent like this.
Tradition DMI synchronous FRU power down DMI Table easily loses, and is difficult to the consistance ensureing DMI and FRU information.
Summary of the invention
For solving the problem, the object of the present invention is to provide the method for the synchronous FRU of a kind of DMI, synchronous FRU information success from BMC, after having upgraded DMI Table, can be saved in NVRAM by the content of DMI Table, power down is not volatile.When during synchronous FRU information failure, upper subsynchronous successful DMI information being read from NVRAM, go to upgrade DMI Table, to ensure the consistance of DMI and FRU information from BMC.
For achieving the above object, technical scheme of the present invention is:
A method of the synchronous FRU of DMI, comprises the steps:
S10:BIOS starts, and creates DMI Table, inserts the default data of DMI Table in DMI Table;
S11: send IPMI order by HOST system and obtain FRU information to BMC;
S12: in time obtaining successful, upgrades DMI Table, and preserves in DMI Table to NVRAM, in time obtaining unsuccessful, reads the last DMI data be saved in NVRAM, upgrades DMI Table.
Further, in step S11, from NVRAM, read the default value of DMI Table, then send IPMI order from BMC, obtain FRU information.
Further, in step S12, upgrade DMI Table by the field of FRU, cover the default value of DMI Table.
Compared to prior art, method synchronous FRU information success from BMC of the synchronous FRU of DMI of the present invention, after having upgraded DMI Table, can be saved in NVRAM by the content of DMI Table, power down is not volatile.When during synchronous FRU information failure, upper subsynchronous successful DMI information being read from NVRAM, go to upgrade DMI Table, to ensure the consistance of DMI and FRU information from BMC.
Term " first ", " second " etc. in instructions of the present invention and claims and above-mentioned accompanying drawing are for distinguishing similar object, and need not be used for describing specific order or precedence.Should be appreciated that the term used like this can exchange in the appropriate case, this is only describe in embodiments of the invention the differentiation mode that the object of same alike result adopts when describing.In addition, term " comprises " and " having " and their any distortion, intention is to cover not exclusive comprising, to comprise the process of a series of unit, method, system, product or equipment being not necessarily limited to those unit, but can comprise clearly do not list or for intrinsic other unit of these processes, method, product or equipment.
Below be described in detail respectively.
With reference to shown in Fig. 1, the method for the synchronous FRU of a kind of DMI of the present invention, comprises the steps:
S10:BIOS starts, and creates DMI Table, inserts the default data of DMI Table in DMI Table;
S11: send IPMI order by HOST system and obtain FRU information to BMC;
In step S11, from NVRAM, read the default value of DMI Table, then send IPMI order from BMC, obtain FRU information.
S12: in time obtaining successful, upgrades DMI Table, and preserves in DMI Table to NVRAM, in time obtaining unsuccessful, reads the last DMI data be saved in NVRAM, upgrades DMI Table.
In step S12, upgrade DMI Table by the field of FRU, cover the default value of DMI Table, thus realize the function of the synchronous FRU of DMI.As one embodiment of the invention, in step S12, guarantee that from BMC, once obtain FRU information is successful.
The method of the synchronous FRU of DMI of the present invention is in BIOS start-up course, first DMI Table is created, the default value of DMI Table is read from NVRAM, send IPMI order again from BMC, obtain FRU information, upgrade DMI Table by the field of FRU, override the default value of DMI Table, synchronous FRU information success from BMC, after having upgraded DMI Table, can be saved in NVRAM by the content of DMI Table, power down is not volatile.When during synchronous FRU information failure, upper subsynchronous successful DMI information being read from NVRAM, go to upgrade DMI Table from BMC.Thus improve the method for the synchronous FRU of DMI, ensure that the consistance of DMI and FRU information.
Server HOST system of the present invention sends IPMI order to BMC, obtains FRU information, and when obtaining the success of FRU information from BMC, after the complete DMI Table of HOST system update, can be saved in NVRAM by the content of DMI Table, power down is not volatile.When HOST system obtains the failure of FRU information from BMC, upper subsynchronous successful DMI information can be read from NVRAM, go to upgrade DMI Table, accomplish the consistance of DMI and FRU information equally.When can ensure failure mutual with BMC in HOST system band, accomplish the consistance of DMI and FRU information.
