Computer system and method of updating authentication information of computer system
First Claim
1. A computer system that connects a first computer device and a second computer device so that the first and second computer devices are capable of bi-directional communication, whereinthe second computer device judges whether the first computer device has legitimate access rights on the basis of authentication information received from the first computer device and, when the first computer device has legitimate access rights, permits usage of the second computer device by the first computer device,a session manager for managing a session configured in a path that connects the first and second computer devices is provided, andthe session manager updates the authentication information while maintaining the session between the first and second computer devices by executing data processing that is in the course of execution before the update of the authentication information is requested via a first session that is provided in the path and which uses pre-update authentication information and by executing data processing that is produced after the update of the authentication information is requested via a second session that is provided in the path and which uses updated authentication information.

Abstract
The storage system of the present invention is able to update a secret while maintaining a session between a host and storage. The administrator configures a new secret for the host and the storage. The session manager issues a request to the storage to open a session that uses the new secret. The session manager opens a session that uses the new secret following authentication. A response to an old command issued prior to the secret update is transmitted from the storage to the host via a session that uses an old secret. A new command following the secret update is transmitted from the host to the storage via the session that uses the new secret. When all the old command processing is complete, the old secret using session is closed.

16. A method for updating authentication information of a computer system that comprises a first computer device and a second computer device that are connected so as to be capable of bi-directional communication via a communication network, comprising the steps of:
-
inputting updated authentication information to the first computer device; inputting the updated authentication information to the second computer device; opening a second session that uses the updated authentication information in a path that connects the first and second computer devices; processing a new command that is issued by the first computer device after the second session is opened via the second session; processing an old command that is issued by the first computer device before the second session is opened via a first session that uses pre-update authentication information; and closing the first session when all the old command processing is complete.
