摘要： PROBLEM TO BE SOLVED: To easily confirm and release a reserve status left in an LDEV by the systemdown of a host etc.
SOLUTION: A server 1 reserves and exclusively uses an LEDV4. When the systemdown of the server 1 is generated due to any failure (S1), the LEDV4 is put in a reserved state as it is (S2). Thus, it is not possible for the server 2 to perform access to the LDEV4. A system manager reads the exclusive control information 6 in a memory 5 through a management terminal 7. Thus, it is possible to display and confirm the reserve state of each LDEV unit on a terminal picture. A user instructs the release of the reserve state from a management terminal 7 (S3). A disk array device 3 receives the release instruction, and partially rewrites exclusive control information 6, and releases the reserve state.

摘要翻译：要解决的问题：通过主机等的系统轻松确认和释放LDEV中保留的状态。解决方案：服务器1保留并专门使用LEDV4。当由于任何故障而产生服务器1的系统故障时（S1），LEDV4被保持为预留状态（S2）。因此，服务器2不可能访问LDEV4。系统管理器通过管理终端7读取存储器5中的排他控制信息6.因此，可以在终端画面上显示并确认每个LDEV单元的保留状态。用户指示从管理终端7释放保留状态（S3）。磁盘阵列装置3接收释放指令，并且部分重写专用控制信息6，并释放保留状态。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To effectively use storage resources by virtualizing external storage resources as internal storage resources.
SOLUTION: A first storage control device 20 comprises a multilayer storage hierarchy of an LDEV (a logical device) 102 connected from LUN 103, and a VDEV (a virtual device) 101 connected under the LDEV 102. At least one of the VDEV 101 is configured by mapping storage resources held by external storage control devices 40A-D. At the time of mapping, functions such as a stripe and an RAID can be added. By using external storage resources as virtual internal storage resources, a variety of functions operable for usual internal volumes (a remote copy, a variable volume function, etc.) can be used for virtual internal volumes, thereby increasing a flexibility of utilization.

摘要： PROBLEM TO BE SOLVED: To unitarily manage a configuration change of a storage system to grasp a latest configuration, and to evaluate reliability in advance when performing the configuration change to suppress occurrence of a failure. SOLUTION: In this storage system, when a host 1 is connected to a switch 2, attribute information of an HBA 1a and attribute information of the switch 2 are stored in a connection information storage part 2C by an FDMI (Fabric Device Management Interface) (S1, S2). Each piece of attribute information is associated, and is managed as combination information. A storage device 3 acquires the combination information from the switch 2 (S3, S4), and requests the reliability of combination thereof from a management device 4 (S5). The management device 4 decides the combination of the HBA and the switch (S6), and notifies the storage device 3 about a decision result thereof (S7). When changing a configuration of the storage system, the reliability of the configuration can be confirmed before starting operation by the configuration after the change, so that the occurrence of the failure can be reduced.

摘要： PROBLEM TO BE SOLVED: To use protocols of an SCSI and a TCP/IP, that is NFS, in different purposes without a plurality of connections or a special apparatus.
SOLUTION: Partitions of each protocol are provided in a magnetic disk 110, and a protocol determination part 106 determines a protocol from header information to check a corresponding partition to prevent wrong access to a different block position to destroy a file system. In the case of TCP/IP, a processing determination part 107 further determines whether it is an NFS command, and an NFS processing part 108 carries out processing as an NFS file system. In the case of SCSI, the protocol is transmitted from the determination part 106 directly to the magnetic disk 110.
