It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein.

The method comprises the steps that if any storage cabinet in the multi-control cluster activates the designated software function, the activation code of the storage cabinet can be used for activating the designated software functions of other storage cabinets in the cluster, so that the designated software functions of the whole multi-control cluster are activated, the corresponding activation codes do not need to be acquired for each storage cabinet respectively and are activated respectively based on the activation codes.
The activation method provided by the application can be applied to a multi-control cluster, and the activation method provided by the application is stored in the multi-control cluster in the form of an application program, and the multi-control cluster executes the application program, so that the activation method provided by the application is realized. The application program may be a stand-alone application program, or may be a functional module, a plug-in, an applet, or the like integrated with another application program.
Next, an activation method provided by an embodiment of the present application will be described with reference to the drawings. Referring to the flow chart of the activation method shown in fig. 1, the method includes:
s101: and analyzing the activation code of the first storage cabinet to obtain the unique identifier of the first storage cabinet.
A storage enclosure is an enclosure to which a storage system corresponds, which may be used to store data. For a storage cabinet, a plurality of special software functions are required to be used by an activated party. In this embodiment, the first storage rack refers to a storage rack that has activated a specific software function, where the specific software function refers to one or more of the feature software functions that need to be activated for use. Each storage enclosure has a unique identification that can be used to characterize the identity of the storage enclosure.
In a specific implementation, the multi-control cluster may initiate an activation application for the first storage enclosure to a server of a service provider to activate a specified software function. Specifically, the multi-control cluster sends an activation request to the server, where the activation request carries the unique identifier of the first storage cabinet and the function identifier corresponding to the specified software function, and thus, the server receives the activation request, and may generate and return an activation code according to the unique identifier of the first storage cabinet and the function identifier corresponding to the specified software function, which are carried in the activation request, and then, the multi-control cluster receives the activation code sent by the server, and activates the specified software function of the first storage cabinet according to the activation code.
Because the first storage cabinet has activated the designated software function and has the activation code corresponding to the designated software function, the multi-control cluster can analyze the activation code of the first storage cabinet to obtain the unique identifier of the first storage cabinet. It should be noted that, in some cases, the first storage enclosure may have a plurality of activation codes, for example, for the first storage enclosure applying for activation of a plurality of specific software functions, the first storage enclosure may obtain one activation code based on each specific software function, and thus, the first storage enclosure obtains a plurality of activation codes, where each of the plurality of activation codes corresponds to one software function.
When the first storage cabinet has a plurality of activation codes, the plurality of activation codes can be analyzed respectively to obtain the unique identifier of the first storage cabinet. It should be noted that the activation code is obtained according to the unique identifier of the first storage cabinet and the function identifier of the designated software function, therefore, a process of analyzing the activation code to obtain the unique identifier of the first storage cabinet is equivalent to an inverse process of generating the activation code by the server, and in specific implementation, the activation code may be processed through an inverse algorithm corresponding to an algorithm used by the server to generate the activation code, so that the activation code is analyzed to obtain the unique identifier of the first storage cabinet.
S102: traversing the multi-control cluster according to the unique identifier to determine whether the first storage cabinet is in the multi-control cluster; if yes, go to S103.
The multi-control cluster is a cluster formed by a plurality of storage cabinets and usually has higher load balancing capacity and more reliable redundancy. The multi-control cluster is stored with unique identifiers corresponding to the storage cabinets forming the cluster, and after the unique identifiers of the first storage cabinet are obtained through analysis, the multi-control cluster can be traversed according to the unique identifiers to determine whether the first storage cabinet is in the current multi-control cluster.
Specifically, if the unique identifier of the first storage cabinet matches with a unique identifier stored in the multi-control cluster, it indicates that the first storage cabinet is in the current multi-control cluster, and if the unique identifier of the first storage cabinet does not match with any unique identifier stored in the multi-control cluster, it indicates that the first storage cabinet is not in the current multi-control cluster.
In this embodiment, if the first storage enclosure is located in the multi-control cluster, the multi-control cluster may be activated based on the activation code of the first storage enclosure, that is, if the first storage enclosure is located in the multi-control cluster, S103 is executed.
S103: and activating the designated software function of the second storage cabinet according to the activation code so as to activate the designated software function of the multi-control cluster.
The second storage cabinet is a storage cabinet except the first storage cabinet in the multi-control cluster. The second storage rack may be one storage rack or a plurality of storage racks, and the number of the second storage racks is not limited in the embodiment of the present application.
When it is determined that the first storage cabinet belongs to the multi-control cluster, other storage cabinets in the multi-control cluster, such as the designated software functions of the second storage cabinet, may be activated based on the activation code of the first storage cabinet, and when the designated software functions of each cabinet in the second storage cabinet are activated, the designated software functions of the entire multi-control cluster are activated.
As can be seen from the above, in the method provided in this embodiment of the present application, if any storage enclosure in the multi-control cluster activates the designated software function, the activation code of the storage enclosure may be used to activate the designated software functions of other storage enclosures in the cluster, so as to activate the designated software function of the entire multi-control cluster, and it is not necessary to obtain a corresponding activation code for each storage enclosure and activate the activation codes respectively.
In order to facilitate maintenance and management of the multi-control cluster, after the designated software function of the multi-control cluster is activated, an activation code and a unique identifier of a storage cabinet activating the designated function can be recorded in a configuration file of the multi-control cluster. The configuration file may be, in particular, Vital Product Data (VPD). When the storage cabinet in the multi-control cluster is changed, for example, a storage cabinet is added or deleted, the configuration file may be updated, and the multi-control cluster may be managed according to the configuration file.
The management process of the multi-control cluster is described below with the storage cabinet deleted.
In some possible implementation manners of the embodiment of the application, if a third storage cabinet in the multi-control cluster is deleted, where the third storage cabinet is any storage cabinet in the multi-control cluster, it is determined whether the unique identifier of the third storage cabinet is the same as the unique identifier of the first storage cabinet; if so, the first storage cabinet is deleted, and accordingly, the activation code of the first storage cabinet is deleted, and based on the result, the designated software function of the multi-control cluster is closed.
It should be further noted that the storage cabinets in the multi-control cluster may be cabinets corresponding to the dual-control storage system, and thus, each storage cabinet includes two controller nodes. If the first controller node in the multi-control cluster is deleted, wherein the first controller node can be any one controller node in the multi-control cluster, whether the unique identifier of the storage cabinet corresponding to the first controller node is the same as the unique identifier of the first storage cabinet is judged, if so, the deleted first controller node is a controller node of the first storage cabinet, based on the judgment, whether a second controller node is deleted can be further judged, the second controller node is a controller node belonging to the same storage cabinet as the first controller node, and if the second controller node is also deleted, the specified software function of the multi-control cluster is closed.
In the above embodiment, if the deleted storage enclosure is not the first storage enclosure, or the deleted controller node is not the controller node of the first storage enclosure, or the deleted controller node is the controller node of the first storage enclosure, but the second controller node is not deleted, the specified software function of the multi-control cluster may be maintained.
Therefore, the activation method provided by the application can be used for realizing the sharing of the whole multi-control cluster based on the activation code of one storage cabinet, the activation cost and the activation workload are reduced, and when the activation code fails, the problem can be quickly positioned, so that the multi-control cluster can be managed in time.

For the first storage cabinet, there are N activation codes, or N certificates, that is, funclLicense1 and 2 … … funclLicense en in fig. 2, where N is a positive integer, and each activation code corresponds to a specific software function. And other storage cabinets in the multi-control cluster, namely a second storage cabinet, can activate the designated software function by using the activation code of the first storage cabinet, so that the whole multi-control cluster activates the designated software function.
