Description
Technical field
The present invention relates to server failure detection field, and in particular to a kind of to carry out server memory diagnosis under linux
Method.The memory diagnosis method can position in the case of linux system does not power off to the memory failure of discovery, from
And fault diagnosis timeliness is greatly improved, and the influence that memory failure runs business to server is reduced, and it is of the present invention
Memory diagnosis method may be used in all kinds of server systems, have good adaptability.
Background technology
With the rapid development of Internet, people are increasing to the demand of server, the application to server is also got over
Carry out more extensive, and then the also more and more higher of the requirement to the indices of server.Server takes longer for work, and property
It can stablize.But after server long-play, the probability to break down increases.Positioning in time is needed once breaking down
And fix a breakdown.The positioning of traditional server memory failure needs server to shut down, and then takes out internal memory progress monomer and investigates one by one
Analysis, but power-off operation can interrupt client traffic, bring the loss of economic interests.
In view of the above-mentioned problems, the present application one kind need not interrupt existing business, failure memory DQ (data are directly positioned
Passage) method.
The content of the invention
Specifically, a kind of method that row diagnosis positioning is internally deposited under Linux environment is claimed in the application, and its feature exists
In the diagnosis localization method specifically comprises the following steps：
1) SAD information is read, confirms the slot position that reports an error；
2) TAD information is read, confirms the channel position that reports an error；
3) RIR information is read, confirms the arrangement position that reports an error；
4) by address mapping table, column and row, Ku Ji and the position in storehouse are confirmed；
5) data are write to the address and reads the data, the data and the data of write-in are subjected to XOR, obtained
The data channel that reports an error simultaneously generates LOG files.
The method that row diagnosis positioning is internally deposited under Linux environment as described above, is further characterized in that, above-mentioned diagnosis is determined
The step of position, can be repeatedly.
The method that row diagnosis positioning is internally deposited under Linux environment as described above, is further characterized in that, above-mentioned diagnosis is determined
Position the step of under linux system automatic running.
The method that row diagnosis positioning is internally deposited under Linux environment as described above, is further characterized in that, by LOG
File analysis, EMS memory error can be navigated to specific passage, CPU, Home agant and DIMM Rank.
Embodiment
The present invention is to provide a kind of method that row diagnosis positioning is internally deposited under Linux environment, its implementation is：
1st, SAD (Decoder) information is read, confirms the socket (slot) that reports an error；
2nd, TAD (destination address decoding device) information is read, confirms the channel (passage) that reports an error；
3rd, RIR (arrangement exchanges scope) information is read, confirms the rank (arrangement) that reports an error；
4th, by address mapping table, col (row), row (OK), bank group (storehouse collection), bank (storehouse) are confirmed；
5th, data are write to the address and reads the data, the data and the data of write-in are subjected to XOR, obtained
Report an error and DQ and generate LOG files.
It it is below the step of specifically performing the diagnostic test：
1st, EccMon programs are copied to linux system
Operating instruction is as follows：
EccMon EFI help license.rtf src syslinux
2nd, EccMon programs are run
The instruction of operation is as follows：
./EccMon i=1000/f=error.xml
I=1000 is circulated 1000 times to set
F=error.xml is that test result is saved as xml document.
Can generation error record LOG files error.xml after program end of run
<ErrorData PhysAddress=" 0000000000000000 " UnkMask=" 3FFFFFFFFFE0 "
ErrBits=" 0000000000020000 " Node=" 0 " HA=" 0 " Chan=" 0 " Rank=" 1 " Count=" 128 "
0verflow=" 0 "/>
<ErrorData PhysAddress=" 0000000000000008 " UnkMask=" 3FFFFFFFFFE0 "
ErrBits=" 0000000000020000 " Node=" 0 " HA=" 0 " Chan=" 0 " Rank=" 1 " Count=" 128 "
Overflow=" 0 "/>
<ErrorData PhysAddress=" 0000000000000010 " UnkMask=" 3FFFFFFFFFE0 "
ErrBits=" 0000000000020000 " Node=" 0 " HA=" 0 " Chan=" 0 " Rank=" 1 " Count=" 128 "
0verflow=" 0 "/>
Parse error.xml files：
ErrBits is converted into binary number, corresponding DQ0-63, Node CPU, HA are that home agent, Chan are logical
Road, Rank are DIMM Rank.
For example, error information is DQ 17, CPU 0, HA 0, Channe 10, Rank 1 in LOG files.
It should be evident that illustrated above is only one embodiment of the present of invention, for those of ordinary skill in the art
For, on the premise of not paying creative work, other technical schemes can also be obtained according to the embodiment, belong to this
Invent the scope of protection.
, can be in linux system not the invention provides a kind of method that row diagnosis positioning is internally deposited under Linux environment
Under powering-off state, the memory failure of discovery is positioned, so as to greatly improve fault diagnosis timeliness, reduces memory failure pair
Server runs the influence of business.After technical solutions according to the invention can also be adjusted, ordinary individual's calculating is applied to
Machine, method simple possible and obvious technical effects, it can be applied in practice extensively.
