    • The present invention provides a storage unit system that can be connected to a plurality of different kinds of networks and a controlling method for a system LU of a storage device control unit required in such a storage unit system. In the storage unit system, to an LDEV of a storage device, it is possible to set a system LU for storing control information in the storage unit system itself and a user LU for writing write data sent from a host device, while a management terminal specifies a system LU or a user LU to set a path definition to the LDEV and a CHN inhibits an access to the system LU from the host device in accordance with distinction specified by the management terminal. Furthermore, a path of the system LU is automatically defined to a backup LU, so that the control information stored in the system LU is backed up to the backup LU.
    • 本发明提供一种可以连接到多个不同种类的网络的存储单元系统和用于这种存储单元系统中所需的存储设备控制单元的系统LU的控制方法。 在存储单元系统中,对于存储装置的LDEV,可以将用于存储控制信息的系统LU设置在存储单元系统本身中以及用户LU用于写入从主机设备发送的写入数据,而管理终端 指定系统LU或用户LU以将路径定义设置为LDEV,并且CHN根据管理终端指定的区别禁止从主机设备访问系统LU。 此外,系统LU的路径自动定义为备份LU,以便将存储在系统LU中的控制信息备份到备份LU。
