Abstract
The invention discloses a method of retaining a system crash log on a POWER system through a BMC (boardmanagement control). A CPU (central processing unit) sends a system log to the BMC and stores the system log in the BMC in real time; the system log is prevented from being written into a Flash for storing BIOS (basic input and output system) FW(firmware), so that the BIOS FW damage risk can be avoided. The CPU sends the system log to the BMC through an IPMI (intelligent platform management interface) protocol. The BMC pre-allocates one memory space for storing the system log from the CPU. After the system crashing, the log before the system crashing can be checked on the BMC. According to the method, the system log is not directly stored into the Flash storing the BIOS FW; the system log is sent to the BMC through the IPMI protocol or other sending modes; the system log is stored into the pre-allocated memory space of the BMC or mounted external storage equipment; when the system crashes, the CPU sends the system log before the crushing to the BMC in real time, so that the all received system logs can be checked on the BMC; the BIOS FW damage risk is avoided.
Description
Technical field
The invention belongs to server application technical field, pass through bmc(boardmanagement more particularly, to a kind of
Control, mainboard management controls) power(ibm a kind of server product title) system crash daily record is entered in system
The method that row retains.
Background technology
When system crash, system journal write deposits bios(basic input and output system, substantially
Input-output system) fw(firmware, firmware) flash in；The prior art has the drawback that: system journal is write
The flash entering is the flash depositing bios fw simultaneously, writes this flash and there is the risk destroying bios fw,
System will be led to cannot to start once bios fw damages.
Content of the invention
For the defect of prior art, it is an object of the invention to provide a kind of right in power system by bmc
The method that system crash daily record is retained is it is intended to solve in prior art because the flash of system journal write is simultaneously
Once depositing the flash of bios fw so that bios fw damages the problem that system will be led to cannot to start.
In the method in power system, system crash daily record being retained by bmc that the present invention provides, will
System crash daily record in power system is retained by bmc, rather than is directly stored in and deposits bios fw's
In flash, thus avoiding damage to the risk of bios fw.
The invention provides a kind of method in power system, system crash daily record being retained by bmc, cpu
In real time system journal is sent to bmc and preserves at bmc, it is to avoid system journal write is deposited bios fw's
Flash, thus avoid damage to the risk of bios fw.
Further, system journal is sent to bmc by ipmi agreement by cpu.
Further, bmc allocates a piece of memory headroom in advance for depositing the system journal from cpu.
Further, described memory headroom is taken and is recycled strategy, deposits elder generation when storing daily record according to daily record
Distribute daily record id afterwards, the id of new daily record distribution is more than the id of old daily record, once this piece internal memory is deposited by system journal
Full, then oldest log information is deleted according to daily record id and be used for depositing up-to-date log information.
Further, oldest daily record refers to the daily record the longest of resting period in system, and up-to-date daily record refers to system
In recently received daily record.
Further, daily record after system crash, before system crash being checked on bmc.
In the present invention, system journal is not directly stored in the flash having bios fw；System journal is passed through
Ipmi agreement or other sending methods are sent to bmc；System journal be saved in bmc predistribution memory headroom or under
Hang External memory equipment；So, once system crash, give because the system journal before collapse is sent by cpu in real time
Bmc, therefore can check all system journals receiving on bmc, it is to avoid destroys the risk of bios fw.
Brief description
Fig. 1 is the method institute base in power system, system crash daily record being retained by bmc that the present invention provides
In system principle diagram.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and
It is not used in the restriction present invention.
Fig. 1 is shown and provided in an embodiment of the present invention in power system, system crash daily record is entered by bmc
The system principle diagram that is based on of method that row retains, provided in an embodiment of the present invention is existed by bmc to illustrate further
The method in power system, system crash daily record being retained, in conjunction with accompanying drawing, details are as follows: cpu is in real time by system day
Will passes through ipmi(intelligent platform management interface, IPMI) agreement sends out
Give bmc, bmc allocates a piece of memory headroom in advance for depositing the system journal from cpu.This memory headroom is taken and is followed
Ring Utilization strategies, the successively distribution daily record id that deposits according to daily record when storing daily record, the id that new daily record distributes is more than old
Daily record id, once this piece internal memory is filled with by system journal, then oldest log information is deleted according to daily record id and is used for
Deposit up-to-date log information.Oldest daily record herein refers to the daily record the longest of resting period in system, and up-to-date daily record refers to
Recently received daily record in system.
Once system crash, give bmc because the system journal before collapse is sent in real time by cpu, therefore can be
All system journals receiving are checked on bmc, including the daily record before system crash.
By system journal being sent to bmc and preserving at bmc, can avoid depositing system journal write
The flash of bios fw, thus avoid damage to the risk of bios fw.
In embodiments of the present invention, system journal is not directly stored in the flash having bios fw；System day
Will is sent to bmc by ipmi agreement or other sending methods；System journal is saved in the predistribution memory headroom of bmc
Or lower extension External memory equipment.So, once system crash, due to cpu by collapse before system journal send in real time
Give bmc, all system journals receiving therefore can be checked on bmc, it is to avoid destroy the risk of bios fw.
As it will be easily appreciated by one skilled in the art that the foregoing is only presently preferred embodiments of the present invention, not in order to
Limit the present invention, all any modification, equivalent and improvement made within the spirit and principles in the present invention etc., all should comprise
Within protection scope of the present invention.
