摘要： 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.

摘要： 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.

摘要翻译： 在数据迁移时，与数据一起，也优选从数据迁移源到数据迁移目的地的数据访问信息。 存储系统连接到计算机2，名称服务器5对发起者和目标之间的相互关系进行控制，并且包括第一存储节点1a和第二存储节点1b。 第一存储节点具有设置第一目标的第一逻辑单元到120a，121a，并且第二存储节点具有第二逻辑单元120b。 对于从第一逻辑单元到第二逻辑单元的数据迁移，第一存储节点将存储在第一逻辑单元中的数据转发到第二存储节点，并且第二存储节点将数据存储到第二逻辑单元中。 第一存储节点还将关于第一目标的信息转发到第二存储节点，并且第二存储节点使用接收到的关于第一目标的信息将目标设置到第二逻辑单元。
