ABSTRACT:
Method and system for reflecting a change of a copy VOL caused by VOL replica means upon a standby party. In a living and standby party computer system for operating original volumes and copy volumes by using volume replica, after having executed a volume replica, the living party informs the standby party that a copy volume is changed and the standby party reflects changed copy volume information upon the self-party. Through this, even after a fault occurs in the living party and party switchover is done, the standby party can access the copy volume on the basis of the information reflected upon the standby party to continue a process.
