Function.
S503: if so, the microcontroller controls in the equipment to be launched except the storage for memory plane information carrying breath is situated between
It is electric under the power supply of other modules outside matter；Wherein, the onboard information is the hardware information of n-th of hardware module.
To allow equipment to be launched during initialization to faulty hardware module unaware, then needing N number of hardware module
Electricity under the power supply of other modules in starting device in addition to the storage medium ceased for memory plane information carrying is treated, to modify storage
Onboard information on medium.During specific implementation, when equipment to be launched is server, microcontroller is then by the electricity of CPU
Source, memory power supply under electricity, retain the power supply of SPD；When equipment to be launched is frame type exchanger, microcontroller then will management
It is electric under the power supply of board, the power supply of business board, it is preserved for the power supply of the storage medium of memory plane information carrying breath；It is set to be launched
It is standby when being separate unit interchanger, the power supply for the CPU that microcontroller then integrates separate unit interchanger, electricity under the power supply of exchange chip, and
It is preserved for the power supply of the storage medium of memory plane information carrying breath.It should be understood that onboard information herein refers to n-th of hardware module
Onboard information.
S504: the microcontroller modifies the onboard information, so that the equipment to be launched is in the initial of restarting
N-th of hardware module is skipped during changing.
During specific implementation, when equipment to be launched is different types of equipment, microcontroller modifies onboard information
Content it is also slightly different, will be made below being discussed in detail.
When equipment to be launched is server, there is one piece of storage region in the EEPROM of each DIMM, it is every for storing
The number for the RANK for including on a DIMM, by taking n-th of DIMM as an example, if n-th of DIMM includes two RANK, the storage region
It is middle to record 11, if DIMM includes four RANK, 1111 are recorded in the storage region.It include below two with n-th of DIMM
For RANK, when first RANK on n-th of DIMM breaks down, microcontroller passes through I2C bus for the storage region
The SPD information of storage is revised as 01, only includes a RANK to characterize n-th of DIMM, second RANK on n-th of DIMM
When failure, then the SPD information that can be stored the storage region is revised as 10, only includes one to characterize n-th of DIMM
RANK.In this way, the initialization to n-th of DIMM, m-th of RANK can be skipped in server restarting, so that clothes
Business device can still be able to initialize successfully, to improve server when the memory grain of some memory breaks down
Robustness.
6 complete descriptions are when equipment to be launched is server with reference to the accompanying drawing, failure separation method provided by the present application.
As shown in fig. 6, microcontroller first controls the power supply electrifying of SPD, then controls the power supply and memory of CPU on a microcontroller after electricity
Power supply electrifying.After the power supply electrifying of each module in the server, CPU passes through I2C bus using BIOS or Boot loader
The SPD information on each DIMM is read, then each DIMM is initialized.Specifically, from first of first DIMM
RANK starts, if initializing successfully, successively carries out, normally to start server.During initialization, if n-th of DIMM
M-th of RANK initialize failure, it is abnormal that the CPU of server then indicates that m-th of RANK of n-th of DIMM of microcontroller occurs,
Microcontroller then controls electricity under the power supply of the power supply of CPU, memory, and retains the power supply of SPD, to modify the SPD letter of n-th of DIMM
Breath.After the completion of modification, then control electric under the power supply of SPD.Again to the power supply electrifying of the power supply of the power supply of SPD, CPU, memory,
Then DIMM is initialized according to modified SPD information after the completion of powering on.
When equipment to be launched is frame type exchanger, microcontroller is when determining that n-th of business board breaks down, then
The hardware state of n-th of business board of modification is wrong (FALL).Again to the failure when to avoid restarting
Business board card carries out power distribution and initialization action, causes board system to block or manages plan using the control of mistake
Slightly, such as failure board is distributed power to, causes the waste of resource.
When equipment to be launched is separate unit interchanger, microcontroller is then repaired when determining that n-th of exchange chip breaks down
The hardware state for changing n-th of exchange chip is mistake, to avoid next time when restarting again to the exchange chip of failure
Initialization so that separate unit interchanger part exchange chip work in the case where can also start.
Herein, it should be noted that, can be first to onboard for storing after microcontroller modifies to onboard information
It is electric under the power supply of the storage medium of information, in the power supply electrifying to other modules in addition to storage medium, so as to be launched
Equipment initializes N number of identical hardware module according to modified onboard information.It is of course also possible to directly to except storage
The power supply electrifying of other modules outside medium, so that equipment to be launched is according to modified onboard information to N number of identical
