There is provided a storage control system in which various controls to a plurality of storage controllers connected to each other can be effectively performed. The storage control system controls first and second storage controllers, in which a second storage controller 10 is connected to a first storage controller 1-1 to which a host system 1-2 is connected. With reference to a memory in which a table defining correspondence relationships between internal logical volumes and a host logical volume 32 of the second storage controller 10 is stored, a channel adapter 1-3 of the first storage controller 1-1 controls power supplies of driving mechanisms of storage devices corresponding to the internal logical volumes.
