Patent ID: 7100016

Claim:
A configuration management method in a computer system comprising a first storage device, a virtualization device which manages a logical volume of said first storage device by a virtual volume which is a virtual logical volume, and a server which can transmit an access request to said first storage device and said virtualization device through a network, for setting up a configuration in said virtualization device, comprising: a first step for obtaining a configuration including a logical volume definition, which is set up in said first storage device; a second step for preparing a logical volume definition of a virtual volume of said virtualization device which virtualizes a logical volume of said first storage device, on the basis of a logical volume definition which is included in the configuration obtained in said first step; a third step for preparing a cache allocation definition of a virtual volume of said virtualization device which virtualizes a logical volume of said first storage device, in case that a cache allocation definition is included in the configuration obtained in said first step, on the basis of the cache allocation definition that said first storage device has and capacity of a cache that said virtualization device has; a fourth step for preparing a port bandwidth allocation definition of a port that said virtualization device has, which is used for an access to a virtual volume of said virtualization device which virtualizes a logical volume of said first storage device, in case that a port bandwidth allocation definition is included in the configuration which was obtained in said first step, on the basis of the port bandwidth allocation definition that said first storage device has and bandwidth capacity of a port that said virtualization device has; and a fifth step for setting up the logical volume definition prepared in said second step, the cache allocation definition in case that the cache allocation definition is prepared in said third step, and the port bandwidth allocation definition in case that the port bandwidth allocation definition is prepared in said fourth step, in said virtualization device, as a configuration.
