摘要： A controller for controlling a logical resource of a storage system comprises a virtual resource preparation section for preparing a virtual resource which is a virtual logical resource, and a real resource assignment section that assigns a real resource which is a logical resource of a real entity to the prepared virtual resource. One or more backup resources which are virtual resources that have not yet been used by a higher-level section that is on a higher level than the controller are prepared by the virtual resource preparation section for one or more of the higher-level section.

摘要： 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.

摘要： In a situation where a host computer or storage system is an initiator and the storage system or another storage system is a target, when the initiator intends to check LUs in the target, if the initiator judges that the number of delay ACKs is set to more than one, it simultaneously issues the same number of check commands—SCSI Inquiry LUN#a and LUN#b—as the number of delayed ACKs, or check commands in multiples of the number of delayed ACK, to the target; and, when receiving check results—SCSI Data-In—in response to the check commands from the target, sends an acknowledgement to the target. Accordingly, when the number of delayed ACKs set in the TCP in the initiator is more than one, the initiator simultaneously issues check commands to the target designating the same number of LUs as the number of delayed ACKs, and the responses will not be influenced by the delayed ACK.

The initiator includes an interface coupled to the network, a processor and a memory. The storage system includes an interface coupled to the network, a memory and a processor. The session management method comprising the steps of: executing, by the initiator, health check for diagnosing a status of a session established between the initiator and the storage system in the case of which no data is input/output to/from the storage device for a first predetermined period; and cutting off and re-establishing, by the initiator, the session with the storage system at a timing of executing the health check in the case of which no data is input/output to/from the storage system for a second predetermined period.

摘要： A network management apparatus is designed so that when reassigning the existing address, the network management apparatus extracts a link with the largest link cost from among links comprising the network based on the network configuration information and specifies a flow routed though the extracted link based on the statistic information; when receiving a path change request and a via link request to request a via link with respect to the specified flow from an external terminal, the network management apparatus selects either one of addresses of an address pair of the specified flow as a change target address; and when changing the selected change target address, the network management apparatus changes the change target address to a candidate address to be assigned by selecting an address, which is routed through a link included in the via link request and has not been assigned, as the candidate address to be assigned.
