Abstract
When virtual machines are activated under a condition in which an assignment request having a storage extent and a storage region origin is designated and an assignment request having only the storage extent designated are mixedly present, the logical partion (LPAR) whose storage origin is designated by flags is regarded as already assigned even when the storage region is not actually assigned, and a work table indicative of the current status of the storage assignment is generated in a not-in-use storage region table. The not-in-use storage region table is generated on the basis of the work table to determine the assignment or non-assignment of the LPAR to be activated, and assignment or non-assignment of a plurality of such not-in-use regions can be judged in an ascending order.
