System and method for operational management of computer system

An operational management server that manages an OS disk image and a server in association with each other, the latter server being adapted to load and execute the OS disk image, the management server comprising:

• an I/O device recognition table for storage of first information relating to an I/O device and used by the OS disk image;
• an I/O device configuration table for storage of second information relating to an I/O device and included in the latter server;
• and
• a processing unit for associating the OS disk image with the latter server when the first information stored in the I/O device recognition table is included in the second information stored in the I/O device configuration information.

A method for operational management in a management server of a computer system including more than one server to be managed and an OS disk image adapted to operate on any one of the servers, the management server being used to manage association between the OS disk image and one of the servers to be managed, the method comprising the steps of:

• acquiring I/O device recognition information including a combination of software control information and physical device configuration information, the software control information being included in the OS disk image related to a first server to be managed, and being used for determining a device control behavior of an OS, the physical device configuration information being used for identifying an I/O device which applies the software control information;
• acquiring physical device configuration information indicating an I/O device configuration of a second server to be managed;
• and
• determining, on the basis of the I/O device recognition information and physical device configuration information acquired by the above steps, whether the OS disk image operates properly when loaded into the second server and executed.
