A first computer server included in a cluster system includes a plurality of network interfaces, a memory, and a processor coupled to the memory. The processor retrieves a first Internet Protocol (IP) address and a second IP address from the memory. The processor initiates a first communication process with a second computer server included in the cluster system via a first network interface of the plurality of network interfaces. The processor sets the first IP address to the first network interface when the first communication process enables communication with the second computer server. The processor initiates, using the first IP address, a second communication process with a first device having the second IP address via the first network interface. The processor obtains a type of the first device and outputs information on the type of the first device in association with information on the first network interface.

Current configuration information of an information processing apparatus, post configuration information after updating a software, configuration information of a network device are stored in a database. A selection of a software image for updating the software of the information processing apparatus and a change of a configuration of the network device are considered, based on the pieces of configuration information. An automation of an operation of updating the software is realized by sending a result of consideration to an agent deployed in the information processing apparatus and causing the information processing apparatus to perform a desired processing.

A file management system which locates files with less processing load and provides more sophisticated file management tasks. A file manipulation command causes a file manipulation hander to execute a file system operation, which involves placement of a given file to a specified directory, thus assigning the specified directory as a parent directory of that file. The file placement operation causes a parent directory record manager to define a parent directory record of by setting thereto the file's parent directory identifier. Afterwards, when a parent directory inquiry about a specific file is issued, a parent directory inquiry handler retrieves the parent directory record of the specified file and outputs the identifier of the specified file's parent directory that is contained in the retrieved parent directory record.

File management system with parent directory search functions

A data processing system having an efficient logging mechanism which stores log records for repairing a file system when its consistency is lost. When there is a transaction attempting to update metadata stored in metadata volumes, a metadata loading unit reads the requested metadata objects out of the volumes and loads them to a metadata cache. At that time, a metadata manager updates its internal database to record from which metadata volume each metadata object has been fetched. Each time the transaction updates a metadata object in the cache, a log collection unit collects a copy of the updated metadata object, together with a volume ID which indicates its home metadata volume. The collected data is temporarily stored in a log buffer, and finally saved into a log volume by a log writing unit.
