<p>At the time of data migration, together with data, information about data access is also preferably taken over from a data migration source to a data migration destination. A storage system is connected to a computer 2, and a name server 5 exercising control over the interrelation between initiators and targets, and includes a first storage node 1a and a second storage node 1b. The first storage node has a first logical unit to 120a, 121a which a first target is set, and the second storage node has a second logical unit 120b. For data migration from the first logical unit to the second logical unit, the first storage node forwards data stored in the first logical unit to the second storage node, and the second storage node stores the data into the second logical unit. The first storage node also forwards information about the first target to the second storage node, and the second storage node sets a target to the second logical unit using the received information about the first target.</p> |
