Abstract
The invention provides a method for automatic dead halt state detecting and resetting of a memory. A power supply control unit is arranged between the memory and a power supply system to control the power interruption and power supply of the memory, a communication mechanism is established between the memory and the power supply unit mutually and comprises a simulation detection mechanism performed by the power supply control unit on the memory, the simulation detection mechanism is used for carrying out state detection on the memory by adopting a form of a simulation client side, and the power supply control unit carries out on/off control on a power supply line according to a 1/0 result returned by the detection mechanism, so that the purpose of controlling system equipment through the power supply control unit is achieved.
Description
Technical field
The present invention relates to the computer memory area of maintenance, specifically a kind of automatic detection of stored device deadlock state and the method that resets.
Background technology
Storer is as the data center of present Client application, generally all be deployed in reliable safe central machine room, or even long-range Disaster Preparation Center, so the daily servicing of storer substantially all is to carry out telemanagement by network connection, but this way to manage be based on can be long-range situation under, under the normal ruuning situation of storer, if but accumulator system itself is because the overweight or unusual generation of IO load, to lay oneself open to the deadlock state, want so maintenance memory, can't realize by long-range connection, and can only go to the storer scene to carry out system and restart, investigate again fault.
The present invention is exactly for such problem, and a kind of method that realizes that storer automatically detects the deadlock state and resets of design helps the user to solve the problem of remote maintenance.
Summary of the invention
The method that the purpose of this invention is to provide a kind of automatic detection of stored device deadlock state and reset.
The objective of the invention is to realize in the following manner, between storer and electric power system, outage and power supply that supply control unit comes control store are set, storer and power supply unit are set up communication mechanism mutually, communication mechanism comprises that supply control unit is to the emulation detection mechanism of storer, emulation detection mechanism adopts the form of emulation client to implement to survey the state of storer, supply control unit is according to surveying machine-processed 1/0 result who returns, supply line is carried out folding control, thereby reach the purpose of coming control system equipment by supply control unit, supply control unit: comprise the state detection module that is connected with storer, with be connected with electric power system control module, concrete steps are as follows:
1) the real-time detection of stored device of state detection module crashes or ossified this special state, detect and use the simulative surveillance strategy, this strategy is to divide a very little space to supply control unit at storer, the storage space that supply control unit utilization mapping is come is as this domain, then simply generate several data at this subregion, then deletion, so constantly circulation creates, deletion, create again, in deletion ... simulate in this way client's practical operation, when supply control unit can not create or delete data, the storer that far-end is described is inaccessible, storer is in a kind of improper ossified or deadlock state, and this time, detection module will the trigger circuit control module be processed;
2) when state detection module detects the abnormality of storer, meeting transmission information is to circuit control module, circuit control module can cut off the power supply to storer, storer has just been realized power-off operation like this, then utilize delay strategy, connect again circuit after spending 1 minute, again to the storer power supply, so just reached the purpose that restarts storer.
The invention has the beneficial effects as follows: just realized by the present invention's design, realized storer automatic detection and recovery to a certain extent, ease for use and the maintainability of product have been improved, design by the present invention, be that storer can be deployed to long-range data center more easily, be convenient to the centralized management control of storer.
Description of drawings
Fig. 1 is processing flow chart.
Embodiment
With reference to Figure of description to explaining below the work of the present invention.
With reference to shown in the upper figure, left side machine is a storer, and design core of the present invention is to increase a reference mark in supply line, and this reference mark is used for the transmission of control circuit with good conditionsi, thereby reaches the purpose of controlling machine by control circuit.
The design core of control node is divided into two parts, and a part is and the state detection module of storer, and a part is the control module of circuit, and the below sets forth respectively:
1. state detection module, its effect is exactly that the detection of stored device crashes or ossified this special state, the present invention designs and uses a kind of simulative surveillance strategy, the reference mark that namely utilizes us to design, divide a very little space to reference mark (may diminish to several K) at storer, the storage space that control node utilization mapping is come is as this domain, then simply generate several data at this subregion, then deletion, so constantly circulation creates, deletion, create again, in deletion ... the practical operation the simulation client so in fact, when the control node can not create or delete data, the storer that far-end is described is inaccessible, storer is in a kind of improper ossified or deadlock state, and this time, detection module will the trigger circuit control module be processed.
2. the function of circuit control module is to realize the control of power supply, the information that namely can send when detecting the abnormality of storer is to circuit control module, then circuit control module can cut off the power supply to storer, storer has just been realized power-off operation like this, then utilize delay strategy, connect again circuit after spending 1 minute, again to the storer power supply, so just reached the purpose that restarts storer.
Embodiment
The control node can select the PC of least significant end to get final product, but will do some changes in design, because we will add the part of circuit control, circuit control design can cooperate chronotron to realize with trigger, flip flop design is fairly simple, gets final product as long as can accept 0,1 signal that software sends; The design of emulation client, come the little subregion of simulant-client connected storage to get final product with regard to the OS with PC, then write a script in system, make it constantly create data of deletion at the subregion of formulating, and each result sent to trigger, when operating successfully, production data position 1 unsuccessfully makes generated data position 0; When trigger receive 1 as a result the time think that state is normal, do not do any action; When receive 0 as a result the time, notice chronotron line disconnection, and beginning timing, circuit on the automatic pressing again after 1 minute. realized like this a process that automatically detects and recover.
Except the described technical characterictic of instructions, be the known technology of those skilled in the art.
