Summary of the invention
In order to solve this problem, propose the outer method for burn-recording of a kind of VR Firmware remote band based on BMC herein.The method is simply effective, can solve when machine room distance maintainer is apart from time remote, be realized the optimization and upgrading of the remote online of the VR circuit to server master board by network, to improve the confession electrical stability of system.Reduce the time on the round road of maintainer, improve the ageing of maintenance.
The technical matters that the present invention will solve and optimize is: when not affecting that on Client line, business is normally run, and realizes the outer burning of remote band of VR Firmware.Its main thought is: cross BMC management network port IP address Telnet machine to be refreshed, perform compiled driver, realize remote reflash and the upgrading of CPU or internal memory VR Firmware on machine room internal fault server master board under system.Business on the line that the method does not need to stop client, and maintainer does not need to enter machine room, can realize safeguarding, can reduce the expense of maintainer at round machine room, and user can be avoided to stop the economy of large scale loss of tape because of business simultaneously.Scheme of the present invention is as follows:
First, in motherboard hardware, the FW burning of VR controller realizes signal wiring by the I2C interface that chip is reserved.In mainboard I2C topological structure, VR controller as slaver(from equipment) occur, therefore, need a master(main equipment) VR Firmware burning.The I2C equipment that PMBUS or the I2C interface of mainboard VR chip is connected with BMC realizes physical interconnection; The method adopted herein is that BMC chip comprises 9 I2C interfaces by selecting the I2C4 on mainboard managing chip BMC as the master of VR controller, optionally one of them.After guarantee I2C topological structure is correct, need to distribute I2C address to 2 CPU VR and 4 internal memory VR respectively, during for ensureing address assignment, in the address realm that I2C address should be supported at VR chip, ensure that the address of each Slaver can not exist address conflict again.The I2C address of setting 6 VR is 0x40,0x08,0x80,0xE0,0x10,0x1C respectively.
Secondly, software aspect, needs I2C Data Transport Protocol to compile generation driver.The effect of this driving is: meeting the VR code file programming of I2C data layout in the NVM of VR chip.Driver reserves three parameter interface: treat the BMC management network port IP address of burning machine, the I2C address of corresponding VR and VR code recordable paper, such as: " inspur_updatevr.sh 10.52.11.196 80 DDR_AB.txt ".Wherein: " inspur_updatevr.sh " represents driver; The BMC IP address of " 10.52.11.196 " representing fault machine; " 80 " represent the I2C address of internal memory AB passage VR controller; The VR Firmware file of burning is wanted in " DDR_AB.txt " representative.
Operation maintenance personnel without the need to entering failed machines place machine room, and when be not related to stop business on subscribers feeder, the long-range burning of Firmware to internal memory on server master board and CPU VR Controller and upgrading can be realized.
Effectively prevent Internet enterprises because of the extensive business brought when fault machine keeps in repair stops the loss that line causes.Can the telemanagement outside machine room realized, and when customer service does not roll off the production line, the various compatibility issues that settlement server system causes because of VR, respond well.Meanwhile, maintainer can be avoided to go to the expense of room management, save O&M cost, improve the ageing of maintenance.
