the power effect units of the electronic devices being related to communication ports of the electronic devices and being the electronic devices themselves or a part of the electronic devices,the management device comprising;
a specification part that specifies a first power effect unit, the power state of which is an ON state from among the plurality of power effect units in the storage system;
a path management part that transmits a path closure instruction, which is an instruction to close a first path passing through the first power effect unit, to the power effect unit having the upper-level port through which the first path passes, or to the upper-level device having the power effect unit; and
a power management part that transmits a switching instruction to switch the power state of the first power effect unit to the power savings state to the first power effect unit or the electronic device having the first power effect unit, whereinall of the respective first paths which pass through the first power effect unit are constituent elements of either multipath.

Abstract
A management device that manages a plurality of electronic devices constituting a storage system specifies a power effect unit, through which a path that cannot be closed does not pass, from among a plurality of power effect units present in the storage system (units whose power states are switched independently), and causes the power state of the power effect unit to be transitioned to a power savings state by closing the path passing through the power effect unit. The power effect units are units, the power states of which are switched independently, and are the electronic devices themselves or a part thereof.
