Firstly the need of explanation, the CPU on mainboard connects one or more storage control module, storage control moduleFor signal, SGPIO (Serial General Purpose Input Output, serial universal input/output) letter will to be storedIt number is sent on each connector of hard disk backboard by connector, cable.Each storage control module connection two is moreA cable (cable and hard disk and hard disk indication lamp correspond).On hard disk backboard, storage signal is connect to each hard disk,SGPIO signal, which connects, connects the indicator light of each hard disk to CPLD, CPLD to carry out lighting operation.In server design, storageThe state of each hard disk indication lamp is arranged by SGPIO signal to SPLD for control control module, and CPLD believes according to the SGPIO transmittedNumber control hard disk indication lamp is lighted and is extinguished.
When to cable self-test, initial command is sent to currently stored control module first, storage control module is receivingCan be sent after to initial command initial SG PIO signal to CPLD, CPLD can be controlled after receiving initial SG PIO signal with currentlyThe present hard discs indicator light (namely the corresponding hard disk indication lamp of current cable to be detected) of storage control module connection is in initialState.Sense command, storage control are sent after present hard discs indicator light is in original state, then to currently stored control moduleModule sends detection SGPIO signal to present hard discs indicator light again after receiving sense command, and CPLD is receiving detectionPresent hard discs indicator light can be controlled after SGPIO signal and executes detection operation, can be sentenced according to the state of present hard discs indicator lightWhether fixed cable corresponding with present hard discs indicator light is correct.
It should be noted that in practical applications, can be detected according to the actual situation to cable, for example, can be withTo one or partly or completely one of storage control module or partly or completely hard disk indication lamp is examinedIt surveys.When whole hard disk indication lamps to whole storage control modules detect, following scheme can be used:
Each storage control module is proceeded as follows according to the first preset order:
Initial command is sent to currently stored control module, so as to currently stored control module by CPLD control and currentlyAll hard disk indication lamps of storage control module connection are in original state；
It is proceeded as follows according to the hard disk indication lamp that the second preset order pair is connect with currently stored control module:

Or use following scheme:
To all storage control modules send initial command, so as to each storage control module by CPLD control with it is eachAll hard disk indication lamps of storage control module connection are in original state；
It is proceeded as follows according to the hard disk indication lamp that preset order pair is connect with currently stored control module:
Sense command is sent to currently stored control module, so as to currently stored control module by CPLD control and currentlyThe present hard discs indicator light of storage control module connection executes detection operation.
Here preset order, the first preset order and the second preset order can in the light of actual conditions determine, this ShenIt does not limit particularly herein please.As it can be seen that cable self checking method provided by the present application, it is contemplated that hard disk indication lamp and survey line to be checkedCable be it is one-to-one, therefore, only need to be to the corresponding hard disk of these cables to detect some or certain or whole cablesIndicator light carries out detection, and can to determine whether cable connects wrong.The process greatly reduces artificial participation, time saving and energy saving,Detection efficiency is improved, and error rate is low.
On the basis of the above embodiments:
As a kind of preferred embodiment, original state is OFF state.
As a kind of preferred embodiment, sense command is sent to currently stored control module, so as to currently stored controlModule controls present hard discs indicator light by CPLD and executes detection operation, comprising:
The first sense command is sent to currently stored control module, so that currently stored control module is worked as by CPLD controlPreceding hard disk indication lamp is lighted；
After a preset time lapses, the second sense command is sent to currently stored control module, so as to currently stored controlModule controls present hard discs indicator light by CPLD and extinguishes.
Specifically, original state here can be OFF state, it is of course also possible to be arranged to other states, such asFor illuminating state, behind control when detecting each hard disk indication lamp first go out again it is bright.
In the present embodiment, when being detected to present hard discs indicator light, it can first control present hard discs indicator light and light,After preset time, then control the extinguishing of present hard discs indicator light.As successively being carried out to multiple hard disk indication lampsDetection, then the effect come out should be that each hard disk indication lamp successively carries out light on and off.Specific length of the application for preset timeIt is short do not limit particularly, determine according to the actual situation.
It is arranged as one example below with reference to Fig. 1 to illustrate:
1, operator operates server at the scene, connects checking mode into cable；
2, CPU sends to all storage control modules and orders, and extinguishes all hard disk indication lamps；
3, CPU sends to storage control module 1 and orders, and lights the indicator light of the corresponding hard disk of connector 1 above it, and 1 secondThe order for closing indicator light is retransmited afterwards；
4, CPU sends to storage control module 1 and orders, and lights the indicator light of the corresponding hard disk of connector 2 above it, and 1 secondThe order for closing indicator light is retransmited afterwards；
5, and so on, until all indicator lights are all lighted and extinguished；
6, whether the bright sequence of operator's site inspection indicator light and predetermined order are identical, that is, are determining cable connection justWhether really.
As a kind of preferred embodiment, present hard discs indicator light is controlled by CPLD in currently stored control module and is lightedAfterwards, before sending the second sense command to currently stored control module, further includes:
Obtain the state of present hard discs indicator light；
Judge whether the state of present hard discs indicator light is identical as preset state, if it is, subsequent step is executed, it is noThen, stop detection, and issue the corresponding cable of present hard discs indicator light and connect wrong prompt information.
As a kind of preferred embodiment, present hard discs indicator light is controlled by CPLD in currently stored control module and is lightedAfterwards, before sending the second sense command to currently stored control module, further includes:
Obtain the state of all hard disk indication lamps of all storage control modules；
Judge whether the hard disk indication lamp lighted is the current indicator light, if it is, subsequent step is executed, otherwise,Stop detection, and issues the corresponding cable of present hard discs indicator light and connect wrong prompt information.
In order to further increase the degree of automation, in the present embodiment, after control present hard discs indicator light is lighted, CPLDIt reads the state of present hard discs indicator light and stores the state of present hard discs indicator light into bus register, CPU passes through totalLine reads the state of present hard discs indicator light, and judges whether the state of present hard discs indicator light is identical as preset state, ifThen to send next sense command to currently stored control module, controlled by CPLD so as to currently stored control module andNext hard disk indication lamp of currently stored control module connection executes detection operation, otherwise, stops detection, and issues current hardThe corresponding cable of disk indicator light connects wrong prompt information.
Specifically, referring to figure 3., Fig. 3 is a kind of hardware connection structure of the storage system of server provided by the inventionSchematic diagram.
When CPLD is designed, after receiving the SPGIO signal that each connector is sent, it is hard to control not only to be decoded into corresponding valueDisk indicator light, but also by the storage of the state of present hard discs indicator light into I2C register, CPU can be read by I2C busTo the LED status in its register.In practical applications, if all hard disks to all storage control modules indicateLamp is detected, then after detecting to present hard discs indicator light, not only obtains the state of present hard discs indicator light, may be used alsoTo obtain the state of other all hard disk indication lamps,
Below with reference to Fig. 2 column, (example is identical as example in above-described embodiment, and different is only that CPU also as one exampleThe state for reading hard disk indication lamp is judged) illustrate:
1, operator is live or operates server by remote mode, connects checking mode into cable；
2, CPU sends to all storage control modules and orders, and extinguishes all hard disk indication lamps；
3, CPU sends to storage control module 1 and orders, and lights the indicator light of the corresponding hard disk of connector 1 above it；
4, CPU reads hard disk indication lamp by I2C and (can be present hard discs indicator light, be also possible to all hard disksIndicator light) state, and judged.When reading the state of all hard disk indication lamp, if connector 1 connected it is hardDisk indicator light is bright, other hard disk indication lamps extinguish, then continues in next step.Otherwise, stop connection checking, the prompt that reports an error has cableConnection error, and can also prompt in incorrect link to the connector of which hard disk backboard, connected with facilitating staff to correctLine.When only reading the state of present hard discs indicator light, judge whether the state of present hard discs indicator light is identical as preset state,If it is, execute subsequent step, otherwise, stop detection, and issue the corresponding cable of present hard discs indicator light connect it is wrongPrompt information.
Such as when reading the state of all hard disk indication lamps, when the connector 1 of storage control module is connected to hard diskWhen connector 3 (should be the connector 1 on hard disk backboard to be connected to) of backboard, that is, there is connection error.At this point, passing through companyThe point modulating signal for connecing the transmission of device 1 can light the corresponding hard disk indication lamp of hard disk connector 3.CPU reads signal and learns the hard of bright lightDisk is incorrect, i.e., identification makes mistake, and CPU can also prompt 1 incorrect link of connector of storage control module to hard disk backboardConnector 3 on, with facilitate staff correct line.
In another example when only reading present hard discs indicator light, when the connector 1 of storage control module is connected to hard disk backboardConnector 3 when, that is, there is connection error.At this point, it is right to light hard disk connector 3 by the point modulating signal that connector 1 is sentThe hard disk indication lamp answered.CPU reads the state of the corresponding hard disk indication lamp of hard disk connector 1 according to preset order, but due to thisWhen the corresponding hard disk indication lamp of hard disk connector 3 it is bright, and the corresponding hard disk indication lamp of hard disk connector 1 goes out, and can determine to deposit at this timeThe cable connection for storing up the connector 1 of control module is wrong, issues the corresponding cable of present hard discs indicator light and connects wrong promptInformation.
5, CPU sends to storage control module 1 and orders, and extinguishes the indicator light of the corresponding hard disk of connector 1 above it；
6, to all hard disks, 3-5 step is repeated, until terminating.
As it can be seen that self-test scheme provided in this embodiment, may be implemented automatically to detect, does not need operator and grasp at the sceneMake or observe, improves the degree of automation.
As a kind of preferred embodiment, in all hard disk indication lamps for all storage control modules that judgement is detectedState it is identical as preset state after, further includes:
The cable for issuing the storage system of detection connects errorless prompt information.
In order to facilitate the operation of personnel's timely learning cable connection status, in all storage control modules that judgement is detectedAll hard disk indication lamps state it is identical as preset state after, also issue the storage system of detection cable connect it is errorlessPrompt information.It further include step 7 namely in examples detailed above: if midway returns to the result for checking OK without reporting an error.
