The present invention provides a technique capable of preventing data loss due to relocation of physical storage devices. When a request to relocate a logical storage area is issued, it is determined if the logical storage area to be relocated, which is composed of the physical storage devices in the source storage apparatus, can be configured in the destination storage apparatus, and if it is, the physical storage devices that constitute the logical storage area to be relocated are switched into a write-inhibit state in the source storage apparatus, and the write-inhibit state of the physical storage devices is maintained until the physical storage devices are set up and the logical storage area to be relocated is configured in the destination storage apparatus.
A computer system comprising a first storage apparatus having a physical storage device in which data of a logical storage area is stored, a second storage apparatus connected to the first storage apparatus via a network, and a control device configured to manage the first and second storage apparatuses, wherein
A method for managing a computer system that includes a first storage apparatus having a physical storage device in which data of a logical storage area is stored, a second storage apparatus connected to the first storage apparatus via a network, and a control device configured to manage the first and second storage apparatuses, the method comprising the following steps performed by the control device:
