Claim 9:
10. A method of managing a computer system comprising:
a storage device of one or more storage devices that store data;
one or more processors;
a management unit,
wherein the computer system has an operation history information including a load of a migration source processor and a volume at each time, a migration determination processor provides a storage volume to which a storage area of the storage device is assigned, and processes data to be input and output via the storage volume, another processor in charge of the storage volume has been predetermined, and
