Abstract
The invention relates to a control method for supporting hot drawing and inserting of a peripheral component interconnect (PCI) board card of an Asterisk server. A management progress is established between an operating system and Asterisk application to monitor inserting and removing of the PCI board card. The operating system is informed to uninstall a PCI board card drive and stop or start an Asterisk service so that a user does not need to inform all users first and then to stop a server for replacing the PCI card board and then opens the server to start the Asterisk service.
Description
Technical field
The present invention relates to a kind of method of automatic identification PCI integrated circuit board, refer more particularly to based on the hot-swappable automatic identification technology of Asterisk hardware.
Background technology
Fast development along with network technology, next generation network is familiar with by everybody, call out software with the core of controlling as next generation network and change everybody and also do not feel strange, the Asterisk as the outstanding person in soft switch is widely used especially.Yet, being widely used simultaneously at Asterisk, the user has also found its weak point on hardware.Wherein the most important is: if a certain PCI integrated circuit board of Asterisk server damaged, need closing server, change the PCI integrated circuit board, then open server, open the Asterisk service.The trouble that so not only operates, but also delayed time of users.Therefore, a kind of technology of user's exigence makes it can be in the situation that closing server not, hot-swappable PCI integrated circuit board, and server can be identified loading automatically.
Summary of the invention
Technical matters to be solved by this invention has been to provide the hot-swappable control method of a kind of Asterisk of realization server PCI integrated circuit board, and it does not need to close the Asterisk server, realizes that the direct heat plug of PCI integrated circuit board is changed.
For solving the problems of the technologies described above, the invention provides the hot-swappable control method of a kind of Asterisk of realization server PCI integrated circuit board, set up contact channel between (SuSE) Linux OS and Asterisk, make Asterisk can in time recognize the insertion of PCI integrated circuit board and remove, automatic mounting unloads PCI Labcard driver program and unlatching or closes the Asterisk service, and need not user intervention.
The present invention specifically comprises the following steps:
Step 1, load a managing process on operating system, with the insertion of monitoring PCI integrated circuit board with remove; When the insertion of PCI integrated circuit board or when removing, managing process will scan by PCI " the PCI integrated circuit board inserts or removes " message;
Step 2, after managing process captures described " PCI integrated circuit board insert or remove " message, send the instruction scan pci bus to operating system, all devices on the identification pci bus;
Step 3, managing process obtain the information of each PCI slot this moment from operating system, comprise the connection status of PCI slot, model, the ID information of the PCI integrated circuit board that the PCI slot is connected, and generate temporary log file to keep a record;
Step 4, managing process send " closing application " instruction to the Asterisk application system, wait for the Asterisk feedback;
Step 5, Asterisk send " service is closed " message to the user who is conversing, and then stop service, are returning to " service is closed successfully " message to managing process;
After step 6, managing process receive that Asterisk returns to " service is closed successfully " message, notice operating system unloading PCI Labcard driver;
Step 7, operating system unloading PCI Labcard driver;
The information of the PCI slot that step 8, operating system are put down in writing according to temporary log file loads the PCI Labcard driver, then sends " loading of PCI Labcard driver " message to managing process;
Step 9, managing process send " opening service " instruction to Asterisk;
Step 10, the service of Asterisk process initiation;
Step 11, managing process deletion temporary log file.
The present invention is owing to having set up a managing process between (SuSE) Linux OS and Asterisk, thereby can understand timely the insertion of PCI integrated circuit board and remove, automatic mounting unloads the PCI Labcard driver and closes or open the Asterisk service, the user need not first to notify a user, closing server again, change the PCI integrated circuit board, then open server, open the Asterisk service.
Description of drawings
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further described in detail.
Fig. 1 is of the present invention based on the process flow diagram of realizing the control method that Asterisk server PCI integrated circuit board is hot-swappable under (SuSE) Linux OS.
Fig. 2 is PCI integrated circuit board provided by the invention main operation chart when inserting or removing.
Embodiment
The invention provides the hot-swappable control method of a kind of Asterisk of realization server PCI integrated circuit board, by set up a managing process between (SuSE) Linux OS and Asterisk, thereby can understand timely the insertion of PCI integrated circuit board and remove, automatic mounting unloads the PCI Labcard driver and closes or open the Asterisk service.Concrete steps are in conjunction with Fig. 1, shown in Figure 2:
Step P1, at first open managing process, managing process enters listening state, and whether monitor has the insertion of PCI integrated circuit board or remove.
Step P2, when the insertion that the PCI integrated circuit board is arranged or when removing, managing process captures " the PCI integrated circuit board inserts or removes " message.Operation steps 1,2 as Fig. 2.
Step P3, managing process can send instruction to linux kernel, requires kernel scanning pci bus, all devices on the identification pci bus.
After equipment on the complete all pci buss of linux kernel scanning recognition, return to scanning result to managing process.Operation steps 3,4 as Fig. 2.
Step P4, managing process read the relevant information of PCI slot, comprise the connection status of PCI slot, the information such as the model of the PCI integrated circuit board that the PCI slot is connected, No. ID, and preserve with the form of temporary log file.As shown in the operation steps 5,6 of Fig. 2.
Step P5, managing process send " closing application " instruction to the Asterisk application system, wait for the Asterisk feedback;
Step P6, Asterisk send " service is closed " message to the user who is conversing; The user that notice is using Asterisk to use, the Asterisk server is about to close.
Step P7, Asterisk stop service, are returning to " service is closed successfully " message to managing process; As shown in the operation steps 7,8,9,10 of Fig. 2.
After managing process receives that Asterisk returns to " service is closed successfully " message, notice operating system unloading PCI Labcard driver;
Step P8, operating system unloading PCI Labcard driver;
The information of the PCI slot that step P9, operating system put down in writing according to temporary log file loads the PCI Labcard driver, then sends " loading of PCI Labcard driver " message to managing process; Operating system according to PCI integrated circuit board ID, loads the PCI Labcard driver according to PCI slot order; As shown in the operation steps 11,12,13,14 of Fig. 2.
After step P10, managing process are received " loading of PCI Labcard driver " message that operating system sends, send " opening service " instruction to Asterisk; The service of Asterisk process initiation.
Step 11, managing process deletion temporary log file, then enter listening state.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
