摘要： In case a fault has occurred in a volume, it was so far difficult to correctly notify a fault by using a host computer which can access the volumes managed by a management computer that integrally manages a plurality of devices constituting a network. The management program of the invention is executed by the management computer connected to computers and to a plurality of storage devices for managing the volumes connected to the computers through a SAN (storage area network). The management program executes a procedure for receiving a notice of fault in the volume from the storage devices, a procedure for receiving volume access control information from a plurality of storage devices for specifying the computers that can access the volumes, and a procedure for notifying the fault in the volume to the computers that are permitted to access the volumes based on the volume access control information.

摘要： In a storage subsystem which is connected to an IP network, by excluding an improper packet, security is heightened, and a performance of communication to a logical unit of a storage subsystem is maintained and secured. In the storage subsystem according to one embodiment, a function which carries out filtering of a packet other than an iSCSI packet is provided. With respect to only the packet passed through the function, its accessibility to the logical unit is filtered. Also, traffic of all received packets, and traffic of each packet sorted out by the two filtering functions are measured, and a traffic log of a packet judged to be discarded by the above filtering is recorded. By using this information, controlling such as a cut-off process of improper communication, QoS securement for normal communication and so on, are carried out.

摘要： When a file server migrates from an existing file server to a new file server, data is allowed to migrate and setting information for a file system can migrate, too. At this time, data migration timing can be arbitrarily designated while a file sharing service is executed without stop and while securing system performance. A file migration program of the new file server is connected in a block level to a volume of the existing file server to acquire file sharing configuration and volume setting information of the existing file server. During the migration of the file server, a file read/write request from the file sharing access program of the host computer is executed for the volume through the block access program of the existing file server on the basis of file sharing configuration and volume setting information of the existing file server so acquired.

摘要： Provided are a communication system and the like capable of making a stable relay route even when a propagation channel is fluctuated by the fluctuation of RSSI. For making a tree-type communication route whose root is a core node, each slave node, after the reception of the latest reset routing packet from a node, judges if the transmission source node should be the parent of the tree-type structure based on the sequential average of the reception power of n routing packets received from the same transmission source node. As the reception power is log-normally distributed in general, an asymptotically stable relay route can be obtained, especially by using the sequential average.
