Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings according to embodiments.
In the invention, in the process of testing the multi-controller storage equipment, part of the controllers in the controllers which normally operate in the multi-controller storage equipment are used as working controllers and are responsible for stable operation of a multi-controller storage equipment system, and other controllers which normally operate are used as controllers to be tested to carry out restart test.
Referring to fig. 1, fig. 1 is a flowchart of a method for testing a multi-controller storage device according to an embodiment of the present invention, and as shown in fig. 1, the method mainly includes the following steps:
step 101, selecting a working controller and controllers to be tested from controllers which normally run in a multi-controller storage device, keeping the working controller normally running, and restarting all the controllers to be tested.
In the invention, in the control of the test of the multi-controller storage equipment, the stable operation of the multi-controller storage equipment needs to be ensured, and the front-end IO request can still be processed. Therefore, at least one controller in the multi-controller storage equipment is kept to normally work, and meanwhile, the rest controllers are subjected to restart testing, so that the front-end IO is not interrupted while the multi-controller storage equipment is tested, and the whole multi-controller storage equipment normally works.
Preferably, one controller is selected from the normally operating controllers in the multi-controller storage device to be used as the working controller, and the other normally operating controllers are used as the controllers to be tested. And keeping the working controller to normally operate, so that the multi-controller storage equipment normally processes the front-end IO request, and simultaneously restarting all the controllers to be tested to perform restart test.
Step 102, after restarting the preset duration of all the controllers to be tested, detecting whether each controller to be tested is started successfully, if all the controllers to be tested are started successfully, returning to execute step 101, otherwise, executing step 103;
after the controller to be tested is restarted, after a preset time period, whether the controller to be tested is restarted successfully or not can be detected, if all the controllers to be tested are restarted successfully, the test of the local wheel to the multi-controller storage device is passed, the next round of test can be continued, otherwise, further processing needs to be executed, and specifically, refer to step 103.
In this embodiment, the operating system of the controller to be tested is successfully started and all the boot-up programs in the operating system are normally started, which are used as the flags that the controller to be tested is successfully restarted, that is, when detecting whether each controller to be tested is successfully started (restarted), it is required to detect whether the operating system of each controller to be tested is successfully started and whether all the boot-up programs in the operating system of the controller to be tested are normally started, if the operating system of the controller to be tested is successfully started and all the boot-up programs in the operating system are normally started, it is determined that the controller to be tested is successfully started, otherwise, it is determined that the controller to be tested is not successfully started.
In this embodiment, whether the operating system of the controller to be tested is successfully started is detected by sending a ping message with a destination address being an IP address of the controller to be tested to the controller to be tested, if the ping message is successful, that is, a response message of the controller to be tested is received, it is indicated that the controller to be tested can normally communicate, and therefore it is determined that the operating system of the controller to be tested is successfully started, otherwise, it is indicated that the controller to be tested cannot normally communicate, and therefore it is determined that the operating system of the controller to be tested is not successfully started.
Under normal conditions, an authorized user can log in the controller, i.e., a user who is authorized to log in the controller by using a certain user name and password.
In order to detect whether all startup programs in an operating system of a controller to be tested are normally started, a user name and a login password of each controller in a multi-controller storage device need to be obtained in advance; when detecting whether all the boot-up programs in the operating system of the controller to be tested are normally started, the method of the prior art can be used to detect whether all the boot-up programs in the controller to be tested are started only by logging in the controller to be tested by using the user name and the login password of the controller to be tested, for example, whether all the boot-up programs are included in the boot-up programs in the operating system of the controller to be tested is checked, if yes, all the boot-up programs in the controller to be tested are started, and if not, all the boot-up programs in the controller to be tested are not normally started.
And 103, marking the unsuccessfully started controllers to be tested as abnormal-operation controllers, executing the step 104 if the number of the normally operated controllers is not more than 1, otherwise, returning to the step 101 for execution.
In this embodiment, the controller to be tested that is not successfully restarted is marked, and no longer participates in the test in the next test, and the controller to be tested that is successfully restarted enters the next test as the controller that normally operates.
And step 104, ending the test flow.
It can be seen from the above method that in this embodiment, in each round of testing of the multi-controller storage device, part of the controllers are selected as the working controllers, and the others are used as the controllers to be tested to perform the restart testing, so long as at least one controller that normally operates in the multi-controller storage device is not less than one, the multi-controller storage device can be subjected to the multi-round testing without manual intervention, and in each round of testing, because the working controller still operates normally, the multi-controller storage device can normally process the front-end IO request. Therefore, by adopting the method of the embodiment, the abnormal test under the unattended condition of the multi-controller storage equipment can be realized, the problem that the restarting fault processing of the controller occurs in a simulation field is solved, and the stability of the storage product is improved.
