The present disclosure involves a method and device for maintaining a session of a network storage device. As an example, there is provided a method of maintaining a session of a network storage device, comprising: storing a profile of the session in a network storage device, the profile describing attributes of the session; migrating a first virtual server associated with the session and managed by a first storage processor in the network storage device to be managed by a second storage processor, the migration causing the session to be disconnected; recovering the session using attributes based on the stored profile; and updating signature of the session. Thus, when migration occurs in a virtual server, the associated session can be maintained.
