A storage system has a storage controller and a RAID group. The storage controller has policy management information such that one failure recovery process among a plurality of differing failure recovery processes is associated with each RAID group, and when an error in a command issued to a RAID group is detected, the failure recovery process associated with the RAID group to which the command was issued is specified on the basis of the policy management information, and the specified failure recovery process is executed.
