摘要： A storage apparatus 10 includes channel devices (each being CHA_PK 11) and microprocessors (each being MP_PK 12). CHA_PK 11 and MP_PK 12 respectively store therein control information being information designating logical volumes (LDEVs) 171 accessible by respective MP_PKs 12. Upon receipt of an I/O request from a management apparatus 20, CHA_PK 11 transmits, based on the control information stored therein, an I/O command to MP_PK 12 having an access right to a logical volume to which the I/O request is directed. In the storage apparatus 10, MP_PK 12 having received the I/O command from CHA_PK 11 judges based on the control information stored therein whether MP_PK 12 itself has an access right to the logical volume, and transmits the control information therein to CHA_PK 11 when judging that it does not have the access right, whereby the control information in CHA_PK 11 is updated.

摘要： A storage system comprising a host device, a storage device, a switching device, and a management terminal is provided. The host device has a plurality of first logical blocks. The storage device has a plurality of second logical blocks. The switching device transfers data between the host device and the storage device through a plurality of paths. The management terminal receives information on the first logical blocks from the host device, receives information on the second logical blocks from the storage device, and generates information showing connecting paths between the first logical blocks and the second logical blocks based on the information on the first logical blocks received and the information on the second logical blocks received. Accordingly, it is possible to get hold of the connected configuration of the first logical blocks and the second logical blocks.

摘要： A storage subsystem includes a disk control unit having a cache memory and disk units under control thereof is connected to a central processing unit through an interface such as FC-SB2 which the central processing unit issues an I/O request including a chain of plural commands and data asynchronously with responses from the disk control unit. The disk control unit executes commands having target data hit on the cache memory independently of the order of receipt of plural commands from the central processing unit, in parallel with the staging of target data of commands resulting in cache misses from a disk unit to the cache memory.

摘要： A personal computer inputs path information for forming a path group and a storage controller manages the path group. For example, a physical path PS#1, a path PS#2 and a path PS#3 are defined as a path group PG#1 and instructed to the storage controller. This indication is stored in a table. Host A recognizes this path group information, too. Host A designates “Persistent Reserve OUT” on the path PS#1. The storage controller recognizes that the path group PG#1 inclusive of this path PS#1 is reserved as a whole. When Host B attempts release this reserve state illegally through a path PS#1 of Host A, Host B issues “Persistent Reserve OUT” command by KEY#1. Because the path PS#1 does not belong to the path group managed by the storage controller, however, the reserve release request is rejected.

摘要翻译： 个人计算机输入用于形成路径组的路径信息，存储控制器管理路径组。 例如，物理路径PS＃1，路径PS＃2和路径PS＃3被定义为路径组PG＃1，并被指示给存储控制器。 该指示存储在表中。 主机A也识别此路径组信息。 主机A在路径PS＃1上指定“持久保留OUT”。 存储控制器识别出包含该路径PS＃1的路径组PG＃1整体被保留。 当主机B尝试通过主机A的路径PS＃1非法释放该保留状态时，主机B发出KEY＃1的“持久保留OUT”命令。 由于路径PS＃1不属于由存储控制器管理的路径组，所以保留释放请求被拒绝。
