Description
Technical Field
The present invention relates to the field of data network communications, and in particular, to a method and an apparatus for starting dual master control devices, and a dual master control device.
Background
In order to ensure the high reliable operation of large-scale communication equipment, it is commonly adopted in the industry to perform redundant configuration on control boards of a system, that is, one system has two board cards which can both serve as control cores, which is called as dual-master control equipment, wherein one board card is a control board and is responsible for the normal operation of the whole system, and the other board card is a backup board card, and when the control boards are abnormal, the backup board card takes over the work of the master control board card, so that the safe and reliable operation of the system is realized.
During the starting process of the double master controls, in the starting process of the main master control, the onboard chip finishes initialization and enters a working state, if the initialization is not finished because the load capacity of the power supply of the single board is weak, the single board is restarted due to power failure, or the single board is restarted due to software or hardware faults in the starting process. After the single board is restarted, because the number of chips working at the BOOT stage is small or the version is started quickly, a certain control board always competes for being the master. Thus, although the other main control can be started normally, the other main control can not compete as the main control at all times, and if the control board which is in the main control in competition fails to be started, the double main control devices can not be started for a long time, and the service is interrupted for a long time. At present, the method for solving the problem is to unplug a control board which is failed to start, or forbid the control board which is failed to start, or manually intervene, and enable another control board to compete as the master through boot menus of two master control single boards. Manual intervention to start the equipment is time-consuming, inefficient, labor-intensive, and in the case of an external field, it is likely that familiar technical support cannot be arranged in time to manually intervene to start the equipment.
In order to solve the problem that the master control board in the related art fails to start the device for a long time due to a failure, an effective solution has not been proposed in the prior art.

The present invention is further illustrated by the following specific examples.
The dual master control device comprises a hardware module and a software module, wherein the hardware module comprises: the software module comprises a first control board, a second control board and other service boards, wherein the software module comprises: the main and standby competition module and the control panel start control module.
The two control boards and other service boards are basic components of the dual-master control network communication equipment, and the starting control module of the control boards can realize that alternative competition is mainly achieved in the starting process of the dual-master control equipment, so that the starting efficiency and success rate are ensured. The starting control method of the control panel stores a field (called as x) in the storage device of the control panel, the storage device must ensure power failure or restart without loss, the x is used for recording the running state of the single board, and whether to execute a punishment strategy is determined according to the running state, namely the value of the x. The punishment strategy refers to punishment on the starting and main-standby competition of the control board, and the punishment strategy is executed, so that the control board can lose the main use, and the partner control board can compete to the main use. The partner control board refers to another control board except the control board in the dual-master control system. Namely the first control board and the second control board are partner control boards of each other.
x is used for recording the running state of the board, and may represent the number of times of starting in which the competition is active, and the definition of x is as follows:
1-60: wherein, odd is used for punishment, even is continuously executed, wherein the value of 1-60 is not fixed and can be changed according to the requirement, and the punishment judgment strategy can be set according to the requirement. For example, the punishment policy may be to reset the partner control board first and reset itself after a certain time delay, or to reset the partner control board first and close the main/standby competition of the control board after a certain time delay. The punishment strategy only needs to ensure that the main backup of the partner control board competes for the main control board. The reset means restarting the single board.
It is worth mentioning that this scheme may also interchange parity policies, i.e. odd numbers are used for continued execution and even numbers are used for penalties, with the effect unchanged.
A flow chart of a dual master device boot method according to a preferred embodiment of the present invention, the method includes the following flows:
the method mainly comprises the following steps:
starting all control boards to respectively execute the following steps, wherein an x field is added in an EEPROM or a flash before the control boards are started, and is used for recording the running state of a single board;
step two, judging whether a partner board exists (namely whether another master control is in place); if the judgment result is negative, executing the third step; if the judgment result is yes, skipping to execute the step four;
and step three, setting x to be 0, and continuing starting the single board. In this case, although not a dual master, the use of only one control board does not affect the activation of the control boards.
Step four, judging the value range of x, if the value range accords with a punishment strategy, resetting the partner control board, delaying for a certain time, and resetting the partner control board; if the penalty strategy is not met, the single board continues to start. The punishment strategy can be that the partner control board is reset firstly, and the control board is reset after a certain time delay. The time of the time delay is determined according to the total starting time of the control board, so that the partner control board can compete for main use after being reset.
An optional implementation manner is that the value range of x is determined, if x is between 1 and 60 and x is an odd number, that is, the penalty policy is satisfied, x is x +1, the partner master control is reset, and after a delay k x seconds, the partner is reset, so that it can be ensured that the partner is started first and the competition is active. If x is between 1 and 60, and x is an even number, and does not meet the punishment strategy, then x is x +1, the execution is continued, and the single board is started as the main master control. If x is in the interval from 1 to 60, setting x to be 1, and continuing to execute, and if the single board is restarted, making penalty strategy starting for the next restart. The value of k may be set as required, and if the master control board needs to compete for the master in n seconds, k may be set to any value greater than 0 and less than or equal to n to ensure that the partner control board can compete for the master control board after being reset and the punished board is restarted quickly. Preferably, the user can preset the time when the master control is easy to fail in the starting process.
And step five, the double master control devices are started successfully. The successful starting of the double-master control equipment means that any control panel in the system is successfully started.
Through the process, the dual-master control equipment can be normally started without manual intervention under the condition that one control board can not be started, so that the starting efficiency is improved, the starting time is saved, and the stability of the system is improved.
The control board starting control module can be used in each stage after the main and standby hardware competitively starts in the starting process of the double-master control device, so that the starting fault caused by the failure of each stage in the starting process can be covered. Preferably, this scheme can be applied in the following two stages.
The first method can be applied to a boot stage, and can avoid the problem that double-master control equipment cannot be started for a long time due to the fact that one control board is failed to start in the boot stage after the boot starts the main-standby competition and before the boot menu is entered.
The second method can be applied to the problem that after board-level driving loading of the main control single board is completed, subsequent starting failure caused by failure of one control board after board-level driving loading is completed can be avoided, and therefore double main control devices cannot be started for a long time.
The method applied in the two scenes has the same strategy and effect, and also ensures that the two main controls can alternately compete as the main control in the starting process of the double main control equipment.
The first step is as follows: and starting the two control boards and executing a boot bootstrap program.
The second step is that: the two control boards respectively open the main and standby competition switches, wherein one main control (main control A) is in competition for main use, and the partner control board (main control B) is in standby use.
The third step: the two control boards respectively execute the starting control module, and at the moment, if the main control A does not execute the penalty strategy, the fourth step is continuously executed; otherwise, executing the fifth step.
The fourth step: the A is continuously started, if the A master control is successfully started, the double master control devices are started, and the A master control is used as a master; otherwise, after the start of the main control A fails, a certain time is reached to trigger the reset of the watchdog, if the competition is standby during the next start, the main control B is used as the main control, and the double main control equipment is successfully started; and if the next start is still in competition for the main use, executing a punishment strategy and executing a fifth step.
The fifth step: and the main control A executes a punishment strategy, so that the main control competition B is mainly, and the starting of the double main control devices is completed.
