Method for displaying the amount of storage use

A method for displaying the amount of storage use in a computer system in which a storage subsystem comprising a plurality of volumes, first servers including a plurality of file systems, and a second server comprising a plurality of file systems and a program for copying a volume in said storage subsystem to a volume in said storage subsystem or a different storage subsystem are connected via a network, the method comprising the steps of:

• acquiring, by said first and second servers, a list of said file systems composing the respective server, the capacity and amount-of-use information about said file systems, and the names of said plurality of volumes which are connected to said list of file systems;
• acquiring, by said first and second servers, a list of volumes composing said storage subsystem and the capacity of each volume of said list of volumes composing said storage system, from said storage subsystem;
• collecting, by a special server, which is one of said first servers, information acquired by the other first servers and said second server;
• acquiring, by said special server, said copy operation from said second server;
• and
• defining, by said special server, the association among various items of information collected according to said copy operation and displaying, by said special server, a list of said storage subsystems used by a specified server or file system, the total volume capacity, and the amount of volume use on a display device of said special server or other server;
• wherein said special server predicts a future capacity of said specified file system in accordance with an increase/decrease during a specific period, and displays a disk capacity that is required for each of said storage subsystems within the current configuration when the capacity of said file system is to be changed to said predicted capacity.

A method for displaying the amount of storage device use in a computer system in which computers each comprising a plurality of file systems and storage controllers having a storage device, which includes a plurality of volumes, are connected via a network, the method comprising the steps of:

• acquiring, by said computers, a list of file systems composing said computers, capacity and amount-of-use information about said file systems, and the names of volumes of said storage controllers connected to said list of file systems;
• acquiring, by said storage controllers, a list of volumes, information about the capacity of each volume of said list of volumes, configurations relating to copy operations performed between said list of volumes within the storage controllers, and configurations relating to copy operations performed between said storage controllers;
• collecting, by a special computer, which is one of said computers, said information collected by the other computers;
• and
• defining, by said special computer, association among various items of information collected according to said copy operation and displaying, by said special computer, a list of said storage subsystems used by a specified computer or file system, the total volume capacity, and the amount of volume use on a display device of said special computer or other computer;
• wherein said special server predicts a future capacity of said specified file system in accordance with an increase/decrease during a specific period, and displays a disk capacity that is required for each of said storage subsystems within the current configuration when the capacity of said file system is to be changed to said predicted capacity.
