ABSTRACT:
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 controller10is connected to a first storage controller1-1to which a host system1-2is connected. With reference to a memory in which a table defining correspondence relationships between internal logical volumes and a host logical volume32of the second storage controller10is stored, a channel adapter1-3of the first storage controller1-1controls power supplies of driving mechanisms of storage devices corresponding to the internal logical volumes.
