Abstract:
1. A computer-readable, non-transitory medium that stores therein a computer program that causes a computer to transfer a virtual volume established on a real volume, the computer program causing the computer to execute: storing rule information in a storage unit of a transfer destination; acquiring first configuration information about virtual volume established on a real volume of a transfer source; acquiring second configuration information about real volume of the transfer destination; generating third configuration information about virtual volume for the real volume of the transfer destination from the first configuration information by reflecting the second configuration information on the first configuration information based on the rule information stored at the storing, wherein the rule information includes a rule applied when there is a difference between sizes of the real volume of the transfer source and the real volume of the transfer destination or a difference between the number of real volumes of the transfer source and real volumes of the transfer destination, or when a way a real volume is shared by nodes is different between the transfer source and the transfer destination; and establishing a virtual volume on the real volume of the transfer destination based on the third configuration information.
