METHOD AND SYSTEM FOR TESTING A NETWORK SYSTEM

摘要

The invention relates to a system and a method for diagnosing a storage area network. A determination is made of a path in the storage system to test. The path includes at least a host adaptor, a link, a device interface or a device. A first test is performed to determine if there is failure in the path. At least one of the path components is added to a suspect list capable of being a cause of the failure. At least one isolation test is performed on at least one of the path components added to the suspect list. The tested path component is removed from the suspect list if the isolation test confirms that the tested path component cannot be a source of the failure. The suspect list is returned to a user to provide information on the path components capable of being the cause of the failure
