摘要： A mount manager and supporting data structures enable automatic identification and re-establishment of logical volumes on non-removable storage devices in a computer system across multiple reboots and reconfigurations. The mount manager generates a redirected name for a new logical volume when a unique volume identifier is presented to the mount manager by the operating system. The mount manager stores the unique volume identifier and the associated redirected name in a persistent mount manager data structure. The mount manager establishes a symbolic link between the persistent redirected name and a non-persistent device name used by the operating system. During the boot process, the mount manager uses the data structure entries identified by the unique volume identifiers of the arriving logical volumes to reconstruct the symbolic links so that references to the redirected name will resolve to the correct non-persistent device name.

摘要： The invention provides a method and system for arbitrating for ownership of a logical quorum resource, such as a logical quorum volume, comprising one or more physical quorum resources so as to form a storage network having a plurality of storage devices. Arbitration and volume management responsibilities are cleanly divided between cluster management software and volume management software. The cluster management software handles the arbitration process without knowing the details of how the logical quorum resource is formed. The volume management software handles the formation and management of the logical quorum volume without having details of the arbitration process.
摘要翻译：本发明提供了一种用于对包括一个或多个物理仲裁资源的逻辑定额资源（例如逻辑定额卷）的所有权进行仲裁以便形成具有多个存储设备的存储网络的方法和系统。集群管理软件和卷管理软件之间的仲裁和卷管理责任划分清晰。集群管理软件处理仲裁过程，而不了解逻辑法定资源的形成细节。卷管理软件处理逻辑法定卷的形成和管理，而无需详细说明仲裁过程。

摘要： A mount manager and supporting data structures enable automatic identification and re-establishment of logical volumes on non-removable storage devices in a computer system across multiple reboots and reconfigurations. The mount manager generates a redirected name for a new logical volume when a unique volume identifier is presented to the mount manager by the operating system. The mount manager stores the unique volume identifier and the associated redirected name in a persistent mount manager data structure The mount manager establishes a symbolic link between the persistent redirected name, which is used by higher layers of the operating system and user applications to address the logical volume, and a non-persistent device name used by the operating system. During the boot process, the mount manager uses the data structure entries identified by the unique volume identifiers of the arriving logical volumes to reconstruct the symbolic links so that references to the redirected name will resolve to the correct non-persistent device name. When the system undergoes physical reconfiguration, the mount manager associates an existing redirected name to a different non-persistent device name if the unique volume identifier is present in the data structure. In this fashion, logical volumes can be removed and restored in the computer without the knowledge of higher layers of the operating system and user applications. Optionally, the mount manager builds an in-memory data structure from the persistent data structure to increase the speed of the identification process.
