And temporal information representes to carry out the moment of assigned operation, and, if when baseboard management controller is confirmed constantly to arrive according to system clock, then carry out assigned operation at current time.
The present invention utilizes the IPMI management interface that BMC follows on the server master board.
For example, automatic on/off test of computer flow process of the present invention is following:
Step (1), under the system boot state, the instrument that utilizes standard to send the IPMI order sends command packet, such as enabler flags=open, booting wait time=10 second, 30 seconds stand-by period of shutdown;
Step (2), whether BMC checks enabler flags for opening after receiving the packet that step (1) sends, if open, the inspection shutdown stand-by period, shutdown command, system closedown are sent in (30 seconds) after the shutdown stand-by period;
Step (3), the BMC inspection booting wait time after system closedown, again the booting wait time (10 seconds) later BMC start boot program, system boot;
Step (4), circulation step (1) is to the process of step (3) in robotization switching on and shutting down test process.
As shown in Figure 2, according to the idiographic flow of the method for testing of the system operation of the embodiment of the invention be:
At first, under the state of system boot, send command packet by IPMI, this command packet comprises three conditions: enable sign, booting wait time and shutdown stand-by period.
Secondly, enable sign by the BMC judgement, if enable to be designated shutdown command, then system's shutdown switch machine test.When enabling to be designated when opening order, BMC judges and waits for the unused time.When the unused time that command packet is set arrived, BMC called shutdown command, system closedown.
At last, after the system closedown, BMC judges and waits for the on time.When the on time that command packet is set arrived, BMC called power-on command, system boot.
When system is in open state once more, receive the command packet of sending again and judge by IPMI, back and forth automatically perform above operation.
In addition, in the present invention, shutdown can remove the stand-by period in the definition of IPMI packet, or realizes the process waited for by external software, and the BMC shutdown process can be realized by external software, script.
According to embodiments of the invention, a kind of proving installation of system operation also is provided, this proving installation is based on baseboard management controller.
As shown in Figure 3, comprise according to the proving installation of the system operation of the embodiment of the invention:
