Abstract
A management apparatus and management method capable of enhancing reliability and safety of the entire system are proposed. When any one of virtual machine no longer satisfies its performance requirement, a business computer notifies a management apparatus of an alert; a priority representing a priority level when switching a logical path is set to each virtual machine; and when the management apparatus is notified by the business computer of the alert, the management apparatus determines a combination pattern, which satisfies performance requirements for all the virtual machines and satisfies a requirement for the priority that is set to each virtual machine, and issues an instruction to the corresponding business computer and/or a storage apparatus so that a combination pattern of each logical path from each virtual machine to a logical volume allocated to that virtual machine will become the determined combination pattern.
