Instead of this, the system administrator may be notified that there is a pair coordinate in which the initial area ID and the arrangement area ID do not match. In this case, however, the system administrator must create a migration plan and manually execute the migration plan.
- a configuration may be presented in which the system administrator is presented with a migration plan for solving it. In that case, the system administrator manually executes the migration plan.
- FIG. FIG. 19 shows how the coordinate plane of the system configuration is defined.

- the coordinate status is “match”.
- FIG. 22 shows a case where the migration plan is executed. Or, it shows how the migration plan is presented to the system administrator. In order to match the area (arrangement area) to which the coordinate P belongs to the initial area, the logical volume constituting the coordinate P is shifted to a high-performance logical volume.

(2)プログラム(構成管理プログラムP30、マシン情報収集プログラムP31)は、入力されたIPアドレスをメモリ上で一時的に保存する。
(3)プログラムは、入力された情報を使って,仮想化サーバへの接続を試みる。
(4)プログラムは、正しく接続できたことを確認したら、仮想化サーバ名と、仮想マシンのホスト名と、仮想マシンの性能等を取得する。プログラムは、それら情報を、IPアドレスと共に仮想マシンテーブル等に格納する。
