Abstract
A storage system and an undo processing method that can facilitate undo processing for configuration change operations that have been performed for storage apparatuses by different administrators. A management server manages the history of configuration change operations it performs for storage apparatuses while a storage apparatus manages the history of configuration changes it makes in itself in accordance with the configuration change operations performed by the management server. When the storage apparatus receives a request to undo a configuration change operation from a management server, if the undo target configuration change operation or its relevant configuration change operations performed after the undo target configuration change operation have not involved a further relevant configuration change operation for another storage apparatus, the storage apparatus performs undo processing only for the configuration change made in accordance with the undo target configuration change operation, and if they have involved a further relevant configuration change operation for another storage apparatus, the storage apparatus makes a request to the management server that performed the further relevant configuration change operation to undo it.
