Abstract

The present invention discloses a storage take-over and switching processing method and device. The method comprises: a storage gateway providing a storage resource logical unit number LUN for a client side; the storage gateway forwarding a received request instruction by which the client side obtains the attribute of the storage resource LUN to a storage device; the storage gateway forwarding the attribute of the storage resource LUN which is returned by a storage device according to the request instruction to the client side, wherein the attribute of the storage resource LUN is used for merging the storage resource LUN obtained from the storage gateway by the client side and another storage resource LUN obtained from the storage device into a multi-path storage resource LUN, to form two paths, and the operation is online switched to the path through which the access to the storage resource LUN of the storage device from the storage gateway is made. The problem that in the prior art the storage gateway comes online and supports the online switching of the client side and thus defects are caused is solved, and online switching of the client side can be realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a storage takeover and switching processing method and device. Background technique [0002] Storage gateways can protect and manage storage devices and are widely used. In order to strengthen the data security on the storage device, the storage gateway needs to take over the storage resources of the storage device, which is conducive to operations such as increasing control and strengthening data security. [0003] Existing storage gateways generally adopt such a takeover method. 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 already have data, and some are empty. For storage resources with data, the storage gateway will create a virtual storage resource mapped to the storage resource. Creating a virtual storage resource is the same as creating a lo...
