The method includes the steps: 1, multiple BIOS and BMC particles are arranged on a server main board, one for system running and others for BIOS and BMC backup; a hardware support setting system-level manager allows switching of the BIOSes and BMCs; 2, a system logic controller monitors running states of the BIOSes and BMCs; on detecting failures of the BIOSes and BMCs, the system logic controller switches the BIOSes and BMCs to backup BIOSes and BMCs, a system is rebooted and activated, and the BIOSes and BMCs are updated online. The method has the advantages that the BIOSes and BMCs are backed up by the method, the problem in BIOS and BMC failure handling during a server running is effectively solved, and online updating of the BIOSes and BMCs of the server is achieved.
Description
Technical field
The present invention discloses a kind of BIOS and BMC backup method, belongs to server program backup field, BIOS and the BMC backup method of specifically a kind of logic-based control.
Background technology
BIOS is the abbreviation of English " Basic Input Output System ", and literally, Chinese is exactly " Basic Input or Output System (BIOS) ".In fact, it is one group of program being cured in computing machine on mainboard on a rom chip, self-check program and system self-triggered program after the program of the most important basic input and output of its in store computing machine, system set-up information, start.Its major function provides the bottom, the most direct hardware setting and control for computing machine.BIOS likely occurs that program code finds mistake when carrying out summation inspection (checksum), therefore cannot start shooting; Hard disk is installed unsuccessfully; The fault of floppy drive etc. cannot be driven.
BMC is the abbreviation of English " Baseboard Management Controller ", and literally, Chinese is exactly " baseboard management controller ".In fact, it is one group of program being cured to a rom chip on mainboard in server product, some parameters that need monitor in its in store server operational process.Its major function is supervisory control system running.
Server product basic demand is that the sustainable operation time is long, but existing BIOS, BMC adopt individual particle design, when a failure occurs, server can only be stopped to run, carry out failture evacuation, cause server use safety rank to reduce.BIOS, BMC design of server individual particle, when upgrade maintenance, also exists and server need be stopped then completing the security hidden trouble of upgrading, and server work is very inconvenient.The invention provides BIOS and the BMC backup method that a kind of logic-based controls, by arranging many particles BIOS, BMC, and effectively solve a difficult problem for BIOS, BMC fault handling when server runs, and achieve server B IOS, BMC online upgrading.
Summary of the invention
The present invention is directed to existing BIOS, BMC and adopt individual particle design, when a failure occurs, server can only be stopped to run, server use safety rank is caused to reduce, and when upgrade maintenance, also existing to stop server then completing the potential safety hazard of upgrading, and the problem that server work is very inconvenient, BIOS and the BMC backup method that a kind of logic-based controls is provided, effectively solve a difficult problem for BIOS, BMC fault handling when server runs, and achieve server B IOS, BMC online upgrading.
The concrete scheme that the present invention proposes is:
BIOS and the BMC backup method that logic-based controls, concrete steps are:
1. on server master board, arrange many particles BIOS and BMC, wherein 1 BIOS and BMC is used as system cloud gray model, and other BIOS, BMC is used as backup; It is changeable to selecting between BIOS and between BMC that system hardware support arranges system-level manager; System logic controller supports BIOS, BMC handover management, and after can completing BIOS or BMC switching, system reboot activates;
2. system logic controller monitoring BIOS, BMC running status, when detecting BIOS, BMC and breaking down, system logic controller switches BIOS, BMC to BIOS, BMC for subsequent use, completion system restart activation, by BIOS, BMC online upgrading.
Described BIOS has CMOS setting program, starts, after arranging, stored in CMOS RAM with hot key; Also there is system bootstrapping load module, the boot graftabl after self-inspection success by disk on relative 0 sector, road 0, allow it run with loading system.
Described BMC has and carries out a multiplex serial port with the port of server console; Three I2C master ports and standby port.
The velocity gauge input that described BMC monitors for rotation speed of the fan, the pulse width regulator controlled for rotation speed of the fan exports, and the button for front panel button and switch inputs; There is remote access and ICMB support.
Described BMC at least has 32 ARM7 processors.
Usefulness of the present invention is: the invention provides BIOS and the BMC backup method of a kind of logic-based control compared with prior art, server master board arranges many particles BIOS and BMC, wherein 1 BIOS and BMC is used as system cloud gray model, and other BIOS, BMC is used as backup; It is changeable to selecting between BIOS and between BMC that hardware supported arranges system-level manager; System logic controller supports BIOS, BMC handover management, and after can completing BIOS or BMC switching, system reboot activates; Greatly improve the security of system cloud gray model, and BIOS and BMC backup method supports BIOS, BMC online upgrading, greatly improves the maintainability of system.
Accompanying drawing explanation
Fig. 1 operating process schematic diagram of the present invention.
Embodiment
Do a step in conjunction with Figure of description to the present invention to illustrate.
BIOS and the BMC backup method that logic-based controls, concrete steps are:
1. on server master board, arrange 3 particle BIOS and BMC, wherein 1 BIOS and BMC is used as system cloud gray model, and other 2 BIOS, BMC are used as backup; It is changeable to selecting between BIOS and between BMC that system hardware support arranges system-level manager; System logic controller supports BIOS, BMC handover management, and after can completing BIOS or BMC switching, system reboot activates;
2. system logic controller monitoring BIOS, BMC running status, when detecting BIOS, BMC and breaking down, system logic controller switches BIOS, BMC to BIOS, BMC for subsequent use, completion system restart activation, by BIOS, BMC online upgrading;
Wherein BIOS chip is mainboard lastblock rectangle or square cake core, mainly deposits in BIOS:
Self-diagnostic program: by reading the content recognition hardware configuration in CMOS RAM, and self-inspection and initialization are carried out to it;
CMOS setting program: in bootup process, starts with special hot key, after arranging, stored in CMOS RAM;
System bootstrapping load module: the boot graftabl after self-inspection success by disk on relative 0 sector, road 0, allows it run to load DOS system;
The driver of main I/O equipment and break in service: because BIOS is direct and system hardware resources is come into contacts with, therefore always for the hardware system of a certain type, and various hardware system is had nothing in common with each other, so there is various different types of BIOS, along with the development of hardware technology, also successively there is different versions in same BIOS, the BIOS of redaction is compared with early version, with better function.
Wherein BMC provides following function:
With the compatibility of IPMI 1.0;
For the velocity gauge input that rotation speed of the fan monitors, the pulse width regulator controlled for rotation speed of the fan exports, and the button for front panel button and switch inputs;
A multiplex serial port is carried out with server console port;
