摘要： One embodiment is directed to a method and apparatus for modifying a configuration of a computer system including a host computer and at least one computer system resource accessible to at least one application program executing on the host computer. The computer system is dynamically reconfigured, without reinitializing the host computer or the application program, to alter a manner in which the at least one application program accesses the at least one computer system resource. Another embodiment is directed to a method and apparatus for responding to changes in a configuration of the computer system impacting a manner in which the at least one computer system resource is accessed by the host computer. Information relating to a first configuration of the computer system at a first point in time is stored, the first configuration relating to a first manner of accessing the at least one computer system resource by the host computer. A second configuration of the computer system at a second point in time is determined, the second configuration relating to a second manner of accessing the at least one computer system resource by the host computer. The second configuration of the computer system is compared with the first configuration to determine whether the second configuration differs from the first configuration. When it is determined that the second configuration differs from the first configuration, the second manner of accessing the at least one computer system resource by the host computer is determined.

摘要： An apparatus has host ports for coupling hosts to data storage devices. The data storage devices are configured into logical storage units, and the apparatus is programmed with a mapping of the hosts to respective logical storage units. The apparatus decodes a host identifier and a logical storage unit specification from each data access request received at each host port, and determines whether or not the decoded host identifier and logical storage unit specification are in conformance with the mapping in order to permit or deny data access of the logical storage unit through the host port. For example, the apparatus includes a switch for routing the data storage access requests from the host ports to ports that provide access to the data storage, and a set of logical volumes of storage are accessible from each of the ports that provide access to the data storage.
摘要翻译：一种装置具有用于将主机连接到数据存储装置的主机端口。数据存储设备被配置成逻辑存储单元，并且该设备用主机到相应逻辑存储单元的映射来编程。该设备从在每个主机端口处接收的每个数据访问请求解码主机标识符和逻辑存储单元规范，并且确定解码的主机标识符和逻辑存储单元规范是否与映射一致以允许或拒绝数据通过主机端口访问逻辑存储单元。例如，该装置包括用于将来自主机端口的数据存储访问请求路由到提供对数据存储的访问的端口的交换机，并且可以从提供对数据的访问的每个端口访问一组逻辑存储容量存储。

摘要： A stacked map storage system has a base mapping of logical data to physical locations in the storage system. Level maps are created either as positive or negative maps of a lower level map. A positive map enables an alternate view while keeping the next lowest level map the same. A negative map allows changes to a lower level map but stores references to the data in itself so the negative map becomes a backup. Negative maps freeze storage in themselves and are read-only. A positive map allows changes to itself and can be used by applications under test to make changes, while not allowing changes to the next lower level map to be made through the positive map. In a preferred embodiment, maps can be stacked to any number of levels, can be shared by applications and hosts, and can either be deleted or merged. Deletion removes the map as though it never existed. A merge overlays an upper view onto a lower view and thus changes the lower view to match the other's state. Both merger and deletion manipulate only the mapping information and do not change or move any stored data.
摘要翻译：堆叠地图存储系统具有逻辑数据到存储系统中的物理位置的基本映射。水平图被创建为较低级别地图的正或负图。积极的地图启用备用视图，同时保持下一个最低水平的地图相同。负映射允许更改较低级别的映射，但存储对数据的引用，因此负映射将成为备份。负图自身冻结存储，只读。积极的地图允许更改自己，并且可以由被测试的应用程序进行更改，而不允许通过积极的地图更改下一个较低级别的地图。在优选实施例中，地图可以堆叠到任何数量的级别，可以由应用和主机共享，并且可以被删除或合并。删除将删除地图，就像它从未存在一样。合并将上视图覆盖到下视图，从而改变下视图以匹配对方的状态。兼并和删除仅操纵映射信息，并且不更改或移动任何存储的数据。

摘要： Method and apparatus for managing access to one of a plurality of raw storage devices in a computer system including a host computer and a storage system. The computer system includes a plurality of logical volumes of data that are visible to the host computer and the storage system and are perceived by the host computer as comprising a plurality of raw storage devices. The host computer includes a file system/LVM mapping layer. In accordance with one aspect of the invention, a request, from a requester having less than system administrator access privileges, to perform an action directly on the one of the plurality of raw storage devices is granted, so that a logical channel is provided to directly access the one of the plurality of raw storage devices without the logical channel being mapped by the file system/LVM mapping layer. Another aspect is directed to a computer system including a host computer comprising an application layer including at least one application program. A plurality of volumes of storage are visible to the application layer, and access privileges less than the root access privileges are assigned to the at least one application program to access the plurality of volumes of storage.
