In order to technical solution provided by the embodiments of the present application is described in detail, the following example is provided:
As shown in Fig. 2, for a kind of interaction flow signal for the control method that master control borad is restarted provided by the embodiments of the present application
Figure, this method can specifically include following steps:
S201, master control receive Restart Request, according to the Restart Request, it is determined whether complete machine is restarted；
In the embodiment of the present application, user can input Restart Request in the page or order line, which can
It to be restarted for complete machine, can also be restarted for master control, can also be restarted for standby master control, the application is real
It applies example and this is not construed as limiting.
Master control receives above-mentioned Restart Request and determines whether the Restart Request restarts for complete machine according to the Restart Request.
For example, the mark of master control is carried in Restart Request and the mark of standby master control, master control receive the Restart Request,
It can determine that the Restart Request is restarted for complete machine.
Wherein, in the embodiment of the present application complete machine restart refer to by more physics frame equipment groups at VSM logic box
The case where separate unit physics frame type equipment complete machine is restarted in border, or refer to physics frame type equipment complete machine in non-VSM logic environment
The case where restarting, the embodiment of the present application are not construed as limiting this.
S202, if complete machine is restarted, the Restart Request is sent to standby master control by master control；
If it is determined that complete machine is restarted, master control modifies preset complete machine reboot flag according to the Restart Request, specifically: root
According to the corresponding relationship of preset Restart Request and complete machine reboot flag, preset complete machine reboot flag is modified.
For example, presetting a complete machine reboot flag in kernel, pair of Restart Request and complete machine reboot flag is preset
It should be related to, as shown in table 1 below:
| Restart Request | Complete machine reboot flag |
| Restart for complete machine | 1 |
| Restart for master control | 0 |
| Restart for standby master control | 0 |
Table 1
According to the corresponding relationship of above-mentioned preset Restart Request and complete machine reboot flag, if it is determined that complete machine is restarted, modification
Preset complete machine reboot flag, is set to 1, if it is determined that master control is restarted or standby master control is restarted, and is modified preset complete machine and is restarted
Mark, is set to 0.
In addition, Restart Request is sent to standby master control by master control if complete machine is restarted.Wherein it is sent to by Restart Request
Before standby master control, master control determines whether standby master control can be used, if standby master control is available, Restart Request is sent to standby master control, no
Then without sending.
S203 after standby master control receives the Restart Request of master control transmission, is modified preset heavy according to the Restart Request
Open mark；
In standby this side of master control, after the Restart Request for receiving master control transmission, modified according to the Restart Request preset
Reboot flag, wherein the reboot flag is the reboot flag of standby master control side.For example, standby master control receives restarting for master control transmission
After request, preset reboot flag is modified, is set to 1.
S204, standby master control sends confirmation message to master control, and the local being locally stored is modified according to the reboot flag
Interface status；
After modifying above-mentioned preset reboot flag, on the one hand, standby master control sends confirmation message, the confirmation to master control
Message is for prompting master control to have received Restart Request, on the other hand, according to the preset reboot flag and local interface shape
The corresponding relationship of state modifies the local interface state being locally stored, and is revised as local interface disabling by local interface available mode
State.
For example, the reboot flag of standby master control side is set to 1, and local interface is locally stored in standby master control after above-mentioned modification
State, as shown in table 2 below.
Table 2
By above-mentioned table 2 it is found that frame type equipment is there are local interface 1, local interface 2, standby master control stores above-mentioned Interface status,
" UP " indicates that local interface is available, and according to the corresponding relationship of the preset reboot flag and local interface state, (reboot flag is set
It is 1, corresponding local interface available mode is revised as local interface disabled status), the local interface state being locally stored is modified,
Local interface disabled status is revised as by local interface available mode, as shown in table 3 below, " DOWN " is revised as by " UP ".
| Local interface | Local interface state |
| 1 | DOWN |
| 2 | DOWN |
Table 3
By above-mentioned table 3 it is found that after by above-mentioned modification, the local interface state that standby master control is locally stored is disabling shape
State.
Wherein during executing local interface disable operation, reboot flag is detected, if reboot flag is 1, no
Call notification chain notifies virtual interface and upper layer application response interface event, can so greatly shorten required for executing interface disabling
Time, it is ensured that standby master control completes local interface disable operation prior to master control.
Wherein, in the embodiment of the present application, local interface refer to by more physics frame equipment groups at VSM logic box
Separate unit physics frame type equipment physical interface in border, or refer to frame type equipment physical interface in non-VSM logic environment, the application
Embodiment is not construed as limiting this.
S205 executes local interface disable operation, and execute weight after master control receives the confirmation message that standby master control is sent
Operation is opened, starts to the active and standby election stage, elects as master control；
Master control indicates that standby master control has received to restart and asks in the case where receiving the confirmation message that standby master control is sent
It asks, local interface disable operation can be executed.It can be seen from the above, local interface refer to by more physics frame equipment groups at
Separate unit physics frame type equipment physical interface in VSM logic environment, or refer to that frame type equipment physics connects in non-VSM logic environment
Mouthful, the disable operation of physical interface is actually executed by master control here.
For example, as shown in table 4 below:
| Physical interface | Physical interface state |
| 1 | UP |
| 2 | UP |
Table 4
By above-mentioned table 4 it is found that frame type equipment is there are physical interface 1, physical interface 2, " UP " indicates that physical interface is available, by
Master control actually executes the disable operation of physical interface, and after executing physical interface disable operation, physical interface state becomes
“DOWN”。
Wherein before executing local interface disable operation, it is default to judge whether modified complete machine reboot flag meets
Requirement execute local interface disable operation if meeting preset requirement and if not meeting preset requirement do not execute local
Interface disable operation.
For example, modifying complete machine reboot flag after above-mentioned determining complete machine is restarted, being set to 1, master control checks the complete machine weight
Mark is opened, is equal to 1, executes local interface disable operation.Wherein during executing local interface disable operation, check that this is whole
Machine reboot flag is equal to 1, then never calls notice chain notice virtual interface and upper layer application response interface event, so can be significantly
Shorten and executes the time required for interface disables.
After executing local interface disable operation, master control can terminate the operation of local process, and dirty data is write back magnetic
Then disk etc. executes reboot operation, start to the active and standby election stage, elect as master control.Here the active and standby election stage refers to
Frame type equipment determines that (master control borad being first powered on is master control to master control board type, and the master control borad being powered on afterwards is standby according to powering order
Master control), such master control is preferentially restarted, is powered on, and is after restart still main master control.
S206, standby master control determine whether master control executes reboot operation according to preset mode, if it is determined that master control is held
Row reboot operation, executes reboot operation, and starting to active and standby election stage is elected as standby master control.
Whether master control, which executes, is determined according to preset mode after executing local interface disable operation for standby master control
Reboot operation, such as message is sent to master control, judge whether that the return message for receiving master control is said if do not received
Bright and master control lost contact, master control have executed reboot operation.
It should be noted that whether executing the implementation of reboot operation, the embodiment of the present application pair for determination master control
This is not construed as limiting.
If it is determined that master control executes reboot operation, standby master control can terminate the operation of local process, dirty data is write back
Disk etc., then executes reboot operation, and starting to active and standby election stage is elected as standby master control.Here the active and standby election stage refers to
Being frame type equipment determines that (master control borad being first powered on is master control to master control board type, and the master control borad being powered on afterwards is according to powering order
Standby master control), so standby master control executes reboot operation after determining that master control executes reboot operation, is after restart still standby main
Control.
In addition, it is pre- that master control judges whether the modified complete machine reboot flag meets if standby master control is unavailable
If requirement；If meeting preset requirement, local interface disable operation is executed.
For example, in the case where complete machine is restarted, if standby master control is unavailable, it is not necessary that Restart Request is sent to standby master control,
Master control judges modified complete machine reboot flag, is equal to 1, executes local interface disable operation.
Furthermore if non-complete machine is restarted, master control is according to the Restart Request, it is determined whether master control is restarted or standby master
Control is restarted, where it is determined whether the implementation that master control is restarted or standby master control is restarted, determines whether that complete machine is restarted with above-mentioned
Implementation it is similar, this is no longer going to repeat them for the embodiment of the present application.
If master control is restarted, master control executes reboot operation, and starting was elected as standby master control, then to the active and standby election stage
Standby master switching is new master control, carries out business processing instead of former master control, masterslave switchover occurs.
If standby master control is restarted, the Restart Request is sent to standby master control by master control, and standby master control receives master control hair
After the Restart Request sent, reboot operation is executed, starting to active and standby election stage is elected as master control, master control still carries out industry
Business processing, will not occur masterslave switchover.
It is true according to preset mode by standby master control by the above-mentioned description to technical solution provided by the embodiments of the present application
Whether fixed master control executes reboot operation, if it is determined that master control executes reboot operation, executes reboot operation, starting to active and standby choosing
In the act stage, masterslave switchover will not be occurred, due to not when so ensuring to carry out complete machine to frame type equipment to restart for standby master control by electing
Masterslave switchover can occur, avoid the influence to service stability and frame type equipment reliability.
It is corresponding with above method embodiment, the embodiment of the present application also provides a kind of control system that master control borad is restarted,
Applied to frame type equipment, the frame type equipment includes master control and standby master control, the system comprises:
Master control receives Restart Request, according to the Restart Request, it is determined whether complete machine is restarted；
If complete machine is restarted, the Restart Request is sent to standby master control by master control；
After standby master control receives the Restart Request of master control transmission, mark is restarted according to Restart Request modification is preset
Will sends confirmation message to master control, and modifies the local interface state being locally stored according to the reboot flag；
After master control receives the confirmation message that standby master control is sent, local interface disable operation is executed, and execute and restart behaviour
Make, starts to the active and standby election stage, elect as master control；
Standby master control determines whether master control executes reboot operation according to preset mode, if it is determined that master control execution is restarted
Operation, executes reboot operation, and starting to active and standby election stage is elected as standby master control.
