Description
Technical Field
The invention relates to the field of communication, in particular to a storage takeover and switching processing method and device.
Background
The storage gateway can protect and manage the storage equipment and is wide in application. In order to reinforce the data security on the storage device, the storage gateway needs to take over the storage resources of the storage device, which is beneficial to increasing the operations of controlling and reinforcing the data security and the like.
The existing storage gateway generally adopts such a takeover method, and the storage gateway first discovers the storage resources of the storage device by establishing a connection with the storage device. Some of the discovered storage resources have data already stored and some are empty. For a storage resource storing data, a storage gateway establishes a virtual storage resource mapped to the storage resource, and as for the virtual storage resource, the flow of establishing the virtual storage resource is the same as that of establishing a Logical Unit Number (LUN for short) of a local storage resource, some private attributes of the storage gateway are set, and only the set size of the storage resource is kept consistent with that of the original storage resource to be taken over, and the storage gateway provides the LUN to a client. The storage gateway will convert the client's access to the virtual storage resource LUN into a remote storage resource LUN access that is taken over. The storage takeover mode does not destroy original data of the storage resources. However, there are problems that because the attributes of the virtual storage resource LUN are generated by the storage gateway, such as a serial number, and these LUN attributes are referenced by the client to determine whether two LUNs can be merged into a multi-path disk, some attributes of the LUN learned by the client from the storage gateway and those of the LUN learned directly from the storage device are inconsistent, which may affect the generation of the multi-path disk, the client may not generate the multi-path disk, the client may not perform multi-path switching, and the service may not be switched from the storage device access to the storage gateway online.
The problem that two LUNs learned by a client cannot be combined into a multi-path disk due to the fact that some attributes of virtual storage LUNs created based on a storage gateway are set to be inconsistent with the LUN attributes of original storage equipment exists, and the problem exists in the prior art. And the storage gateway sends a protocol request command for acquiring the LUN attribute to the storage equipment, and the attribute of the virtual storage LUN is filled with the acquired real LUN attribute value. However, this solution has difficulties in implementation, such as compatibility, because the storage devices hosted by the storage gateway may be of different manufacturers and models. For example, the protocol command requesting the LUN attribute has multiple formats, and the storage gateway initiates a LUN attribute protocol command requesting a format, and some storage devices do not necessarily support a response. The storage gateway actively acquires the attributes of the takeover LUN to notify the attributes of the LUN, which is a real takeover mode, can only be supported by specific and limited storage devices.
An effective solution is not provided yet for the problem that the storage gateway in the related art has defects if the storage gateway supports the client-side online switching.

Because the storage gateway directly forwards the received request instruction for the client to obtain the attribute of the storage resource LUN to the storage device, and forwards the attribute of the storage resource LUN returned from the storage device according to the request instruction to the client, that is, the storage gateway is realized by a transparent transmission mode without modifying the format of the request instruction, the mode can ensure that the attributes of two LUNs seen by the client are consistent, and the multi-path software can combine the two LUNs into a multi-path disk and support multi-path switching.

The following examples are provided to further illustrate the present invention.
The embodiment of the invention can support the storage takeover of the client-side online switching, can solve the problem that the client-side can switch the service to access from the storage gateway only by interrupting the on-way service because the storage gateway does not support the client-side online switching in order to add the storage gateway in the storage application to reinforce the safety of the stored data, and the like, can support the client-side online switching, and can also continue to reinforce the safety of the stored data. Fig. 7 is a block diagram of a storage gateway taking over a storage device according to an embodiment of the present invention, and as shown in fig. 7, the technical solution of the embodiment of the present invention is applied to a storage gateway to provide transparent transmission and security reinforcement functions. The storage gateway establishes connection with the storage device first, and discovers the storage resource of the storage device. For storage resources with data, the storage gateway creates virtual storage resources and a mapping thereof. After the client end and the storage gateway are connected, the client end initiates a request LUN report command to the storage gateway in the first step, the storage gateway analyzes that the request command sent by the client end is the request LUN report command, and the storage gateway notifies all LUNs meeting the conditions to the client end. The client then queries the LUN attribute information for each acquired LUN. The storage gateway analyzes that the request command sent by the client is a command for acquiring the LUN attribute, does not directly respond, forwards the content of the request command to the storage device without changing the content, waits for the response of the storage device, and forwards the response content to the client when receiving the response of the storage device. In this process, the storage gateway is in a forwarder role between the client and the storage device. In other processes, the storage gateway does not act as a forwarder. When the storage gateway recognizes that the client command is about requesting to read and write the LUN data or the storage device responds to the read and write LUN data, the storage gateway performs processing for reinforcing the data security.
The important point of the technical scheme is that transparent transmission is performed aiming at the command for acquiring the LUN attribute. The realization of command transparent transmission is based on technology, and the interface provided by the SCSI general driver can realize transparent transmission. After the storage gateway transparently transmits the LUN attribute acquisition command of the client, the client multipath software can combine the LUN learned from the storage gateway and the LUN learned from the storage equipment into a multipath LUN to form the LUN from two paths to the storage equipment. With this condition, the client can switch the traffic that is going on with the storage device to enter from the storage gateway before reaching the storage device. Storage gateway uplinks do not require interruption of client traffic.
Fig. 8 is a flowchart of a method for a storage gateway to take over a storage device according to an embodiment of the present invention, as shown in fig. 8, the method includes the following steps:
s802, the storage gateway establishes connection with the storage equipment and initiates a request for taking over LUN to the storage equipment;
s804, the storage device informs the storage gateway of the LUN to be taken over;

s818, the storage device responds LUN attribute to the storage gateway;
s820, the storage gateway responds the LUN attribute of the storage device and forwards the LUN attribute to the client;
