Abstract
A new storage unit is installed such that installation costs are suppressed and functions of the new storage unit can be utilized sufficiently. An access right is changed such that the new storage unit (second storage unit) can access an existing first storage unit (S502). A logical device relating to a storage device of the first storage unit is assigned to a logical device of the second storage unit (S503). Path definition and device recognition in a host computer are performed such that the host computer can access the assigned logical device of the second storage unit (S504, 505). Input-output setting of the host computer is changed such that processing of an input-output from the host computer to the device of the first storage unit is requested to the second storage unit (S506). Seleted figure: FIG. 5.
