    Abstract: PROBLEM TO BE SOLVED: To provide a failure tracking method for a system having a virtual layer.
    SOLUTION: A stack system detects an error in a user application interface, and identifies an error being a relevant bottom cause in a much lower stack level, and prepares an error trace entry concerning the error, and associates an error log identifier with the error trace entry, and prepares an unique error identifier in the plurality of host systems of the stack system from the combined error log identifier and error trace entry. When there is high possibility that any failure is generated in a service due to the error being the bottom cause, the error identifier is transmitted to an arbitrary service request side through the user application interface of one or more host systems. Thus, the error detected by the user application interface of one or more host systems is associated with the error being the bottom cause in the stack level below a virtual layer.

    解决方案：堆栈系统检测用户应用程序界面中的错误，并在较低的堆栈级别中识别作为相关底层原因的错误，并准备与错误相关的错误跟踪条目，并将错误日志标识符与 错误跟踪条目，并从组合的错误日志标识符和错误跟踪条目在堆栈系统的多个主机系统中准备唯一的错误标识符。 当由于错误是底部原因而在服务中产生任何故障的可能性很高时，错误标识符通过一个或多个主机系统的用户应用接口发送到任意服务请求侧。 因此，由一个或多个主机系统的用户应用接口检测到的错误与作为虚拟层下方的堆栈级别的最低原因的错误相关联。 版权所有（C）2005，JPO＆NCIPI

    Abstract: A method implemented in a computer infrastructure having computer executable code having programming instructions tangibly embodied on a computer readable storage medium. The programming instructions are operable to determine whether a target disk of a map contains data unavailable to a downstream disk from an upstream disk in a FlashCopy cascade and detect whether the downstream disk has a copy of the data. Additionally, the programming instructions are operable to copy the data from the target disk to the downstream disk, if the target disk of the map contains data unavailable to the downstream disk from the upstream disk and the downstream disk does not have the copy of the data. Furthermore, the programming instructions are operable to refrain from copying the data from the target disk to the downstream disk, if the target disk of the map does not contain data unavailable to the downstream disk from the upstream disk or the downstream disk does have the copy of the data. Moreover, the programming instructions are operable to remove the map from the FlashCopy cascade.

    Abstract: Storage control apparatus is operable in a network of storage controller nodes having an owner node operable to control locking of a region of data during I/O activity, a messaging component operable to request locks, grant locks, request release of locks and signal lock release. The apparatus comprises an I/O performing component to perform I/O on data owned by any owner node, subject to compliance with lock protocols controlled by the owner node. Any Flash Copy image of the region of data is maintained in a coherency relation with the region of data, and the I/O performing component is operable to cache a previous positive confirmation that the region of data has been left in a coherency relation with any said Flash Copy image, and to perform I/O activity on the basis of said previous positive confirmation.

    Abstract: PROBLEM TO BE SOLVED: To provide a high-function storage area controller which is connected in an n-way storage area configuration provided with a shared storage area.
    SOLUTION: A storage area controller in a network is equipped with an I/O execution component, a component for allocating the right of ownership of metadata concerned with data to an owner storage area controller node, a lock manager for controlling a lock of the metadata during I/O, and a storage area constitution element for transferring messages between storage area controller nodes to request the state of the metadata to allow a lock and also request the lock to be reset to send an unlock signal. Then I/O is carried out on data whose metadata are possessed by an arbitrary owner storage area controller node on condition that a metadata lock protocol controlled by the owner storage area controller is based upon, and consistent relation between an arbitrary copy of held data and the data is held upon occasion.
