Abstract
In a computer system, even when the virtual storage capacity of pools is increased, it is possible to keep the availability of each pool at least at a desired level. The managing server compares a reference value beforehand stored therein with an evaluation value of availability which represents a degree of resistivity against destruction, the degree being derived by use of physical configuration information which is obtained from the controller and which is associated with the pool; and determines necessity of addition of an element to the pool if the availability evaluation value exceeds the reference value and indicates the addition of the element to the pool to the storage apparatus.
