ABSTRACT:
In case a fault has occurred in a volume, it was so far difficult to correctly notify a fault by using a host computer which can access the volumes managed by a management computer that integrally manages a plurality of devices constituting a network. The management program of the invention is executed by the management computer connected to computers and to a plurality of storage devices for managing the volumes connected to the computers through a SAN (storage area network). The management program executes a procedure for receiving a notice of fault in the volume from the storage devices, a procedure for receiving volume access control information from a plurality of storage devices for specifying the computers that can access the volumes, and a procedure for notifying the fault in the volume to the computers that are permitted to access the volumes based on the volume access control information.
