One or more target components of a system that are not associated with an active initiator are identified, where the identifying is based on information regarding zones of devices in the system. The devices in each of the zones include at least one initiator and at least one target component accessible by the initiator. The information describes accessibility of devices between the zones. A power management procedure is performed with respect to the identified one or more target components that are not associated with an active initiator to place the identified one or more target components in a reduced power state.
