摘要： In a network computing environment, in which data stored at a primary storage system, is mirrored from the primary storage system to a secondary storage system, a selection may be made to direct an input/output operation such as a read operation, for example, to the secondary storage system instead of the primary storage system in order to improve operations. For example, a read operation may be directed to the secondary storage to improve the read operation response time. In other aspects, a read or other input/output operation may be directed to the secondary storage to improve utilization of the resources of the secondary storage system. Other aspects are described.

摘要： Provided are a computer program product, system, and method for an application to provide data attributes to a storage manager to use to select a storage tier to use for a data set management operation. Each storage tier has storage devices with different storage attributes. The application determines data attributes of a data set for which a data set management operation is to be performed based on an application intended usage of the data set. The application sends the determined data attributes and a data set management command to the storage controller to cause the storage controller to use the determined data attributes to select one of the storage tiers of storage devices for performing the data set management operation specified by the data set management command.

摘要： A method for reducing data transfers while eliminating data loss during database replication includes receiving one or more database log write operations caused by an application making updates to a database. The method also includes writing the one or more database log write operations on a database log stored at a primary site and asynchronously mirroring the database log to a secondary storage device located at a secondary site. The method also includes synchronously storing the one or more database log write operations on a secure storage unit at the primary site and receiving an indication of a disaster event at the primary site. In response to the indication of the disaster event, transmitting only the one or more database log write operations stored to the secure storage unit during a time interval to the secondary storage device.
摘要翻译：一种减少数据传输同时消除数据库复制期间的数据丢失的方法包括接收一个或多个数据库日志写入操作，这些操作是由数据库进行更新所引起的。该方法还包括将一个或多个数据库日志写入操作写入存储在主站点上的数据库日志，并将数据库日志异步镜像到位于辅助站点的辅助存储设备。该方法还包括将一个或多个数据库日志写入操作同时存储在主站点上的安全存储单元上，并且在主站点处接收灾难事件的指示。响应于灾害事件的指示，在时间间隔内仅将存储到安全存储单元的一个或多个数据库日志写入操作发送到辅助存储设备。

摘要： A storage controller is configured to communicate with a host over a first storage area network. Data controlled via the storage controller is mirrored to another storage controller over a second storage area network. The storage controller receives a request from the host to provide read diagnostic parameters of the second storage area network. In response to receiving the request, the storage controller secures the read diagnostic parameters of the second storage area network. The storage controller transmits the read diagnostic parameters of the second storage area network to the host.

摘要： A computer-implemented method for transferring a reserve to a target host, according to one embodiment, includes granting to a source system, by a control unit, a reserve for a volume of a storage device. A push reserve command is received from the source system. The push reserve command specifies: a transfer of the reserve to a target system, parameter data identifying the target system, and path information specifying the source system. The reserve is transferred only to the target system in response to release of the reserve by the source system.

摘要： A method for suppressing data mirroring between a primary storage system and a secondary storage system is disclosed. In one embodiment, such a method includes defining a data class with an attribute designed to suppress mirroring of data from a primary storage system to a secondary storage system. The method assigns a data set to the data class, thereby causing the data set to inherit the attribute. In certain embodiments, assigning the data set to the data class includes recording the attribute in one or more of a volume-table-of-contents (VTOC) and a catalog used to reference the data set. The method automatically suppresses mirroring of the data set from the primary storage system to the secondary storage system in accordance with the assigned attribute. A corresponding system and computer program product are also disclosed.
