A volume control system in a storage area network environment, which is capable of executing volume operation requests in multiple stages, and is also capable of canceling an erroneous volume operation even after the operation has been executed by the user. A volume operation request for executing run commands from the user is analyzed, and parameters for executing the volume operation request are created by a program that operates the storage apparatus. Each of the parameters is provided with an attribute indicating as to whether cancellation is possible or as to when the execution is to be performed. If cancellation of the run command is possible, a parameter for canceling the run command is created simultaneously. The run commands may be executed on the basis of the parameters after verifying by a simulation as to whether or not the various parameters created are correct. At this point, the user may select whether to execute the run commands promptly or in stages. When the user selects executing the run commands in stages, the user registers execution conditions for executing the run commands. In the event the user makes a cancellation request before the registered execution conditions are fulfilled, any of the run commands that has been executed can be cancelled by using cancellation parameters.

1. Field of the Invention
The present invention relates to a volume management technology for storage area networks, which enables delaying the execution of run commands at the request of the user and even canceling the run commands after their execution at the request of the user.
2. Related Background Art
FIG. 1 is a conceptual diagram illustrating a volume management system in accordance with an embodiment of the present invention.
FIG. 2 shows a function block diagram and a hardware configuration of the volume management system of the present embodiment.
FIG. 3 shows a data structure of a command list control table that is created in the volume management system of the present embodiment.
Descriptions are made below as to a volume control method that enables execution of volume operations in multiple stages, and that enables the cancellation of commands until execution conditions for the commands registered by the user are fulfilled.
First, FIG. 2 is used to explain a hardware configuration and a function block of the volume control system in accordance with an embodiment of the present invention.
A volume control system 200 is typically formed form a CPU 210, a main storage apparatus 220, an external storage apparatuses 202 such as magnetic disks, a storage area network 203 to be operated and managed, which includes a server 204, a switch 205 and a storage 206, and a plurality of terminals 201.
