Abstract
A method for rearranging a logical volume including arranging a logical volume rearranging program on a particular server and using the logical volume rearranging program to acquire server/storage mapping information from each server and performance information from each storage subsystem. Moreover, the logical volume rearranging program acquires request I/O (Input/Output) performance and a rearranging rule for each application set by a user. Furthermore, the logical volume rearranging program determines a destination by using the logical volume rearranging destination parity group specified by the user according to the aforementioned information, and rearranges the logical volume according to the storage subsystem performance and the request I/O performance of each application.
