Abstract

Before an active program replacement is carried out, a storage controller confirms a communication state between a redundant storage controller having a redundant configuration with the storage controller and the second storage device, and prohibits, in a case where an abnormality is detected in the communication state between the redundant storage controller and the second storage device, the active program replacement of the first storage controller. This inhibits occurrence of system down when active firmware replacement process is to be carried out in a storage system including multiple storage devices connected to one another.
