摘要： Methods and devices are provided for sharing data across two or more different clusters. An operating system (OS) in a cluster checks a metadata record of a file system of a shared device to retrieve path group identifiers (PGIDs). A control unit list of the shared device is checked to retrieve PGIDs that are active on the shared device. An input/output supervisor (IOS) record in a couple dataset is checked to retrieve PGIDs in the cluster. The metadata record, control unit list, and IOS record are compared, and if a PGID is found in the metadata record that is not in the IOS record and if the found PGID is not in the control unit list, the found PGID is not active on the shared device. The found PGID of the different cluster is removed from metadata record, and members of the cluster can R/W to file system.
摘要翻译：提供了用于在两个或多个不同集群之间共享数据的方法和设备。集群中的操作系统（OS）检查共享设备的文件系统的元数据记录以检索路径组标识符（PGID）。检查共享设备的控制单元列表以检索共享设备上活动的PGID。检查几个数据集中的输入/输出监视器（IOS）记录以检索集群中的PGID。比较元数据记录，控制单元列表和IOS记录，并且如果在不在IOS记录中的元数据记录中找到PGID，并且如果找到的PGID不在控制单元列表中，则找到的PGID不活动在共享设备上。从元数据记录中删除不同集群的已找到的PGID，并且集群的成员可以将R / W转换为文件系统。

摘要： A method for maintaining data integrity of a storage device is provided. A request is received to create an access monitoring session for a data range on a volume of the storage device. A session identification (ID) is determined for the access monitoring session for data range on the volume. An entry is created in an access monitoring session table for the session ID, and the entry adds the access monitoring session with session ID for the data range on the volume to the access monitoring session table. Request parameters are included in the request to create the access monitoring session. The request parameters denote access to the data range on the volume for the session ID and are stored in the access monitoring session table. Access is controlled to the data range on the volume for the session ID based on request parameters stored in the access monitoring session table.
