摘要： Volume configuration data management systems and methods are described. A logical volume provider maintains an epoch number on each of the extents comprising a volume. Upon each change in the configuration of the volume, the epoch number on each of the currently online extents is updated. When a volume is discovered and a request is made to bring the volume online, the logical volume provider can compare the epoch numbers on the extents to determine if the volume data is consistent across each of the extents, or if an extent contains stale data due to a transitory outage.

摘要： Systems and methods for creating and maintaining a stacked volume using one more volumes or extents of a storage subsystem is disclosed. The systems and methods define a hierarchy of operations and components that process operations. The hierarchy includes plex operations for an entire volume, mapping operations that concatenate volumes and/or extents, plex operations for a volume or extent that is a sub-component of a stacked volume. The hierarchy also includes striping operations that create and maintain storage volume stripes comprising sub-volumes and/or extents. In addition, the hierarchy includes configuration operations that operate directly on a storage volume through a hardware or software volume provider. Together, the hierarchy defined allows a flexible, extensible mechanism to build stacked volumes that provide for increase performance, fault tolerance, and/or aggregate volume size, while elimination volume combinations that can cause performance problems.

摘要： A storage management system in which a plurality of volume providers maps logical storage volumes onto one or more storage devices within a stand-alone computer or within a storage network. A common volume manager executing on a computer within the storage network selectively communicates commands to one or more of the volume providers in order to control the storage devices. The inventive storage management system seamlessly integrates management of the vendor-specific volume providers. The common volume manager provides a common application programming interface (API) by which applications are able to control and monitor hardware and software volume providers without requiring detailed knowledge of the volume providers or the underlying storage devices. The common volume manager aggregates response information from the volume providers and communicates the aggregated information to the software application that issued the storage management request. The interface is extensible so as to support provider-specific storage management requests and conforms to a component object-model (COM) interface.

摘要： A storage management system in which a volume provider incorporates an application programming interface (API) for receiving storage access information that characterizes high-level input/output (I/O) attributes of the storage volume such as intended access patterns, a desired level of fault handling and optimization preferences. The volume provider and the underlying storage devices conform to the specified attributes as best as possible and resolve any conflicts with the communicated attributes. The volume providers monitor the storage volumes and may reconfigure the storage volumes in order to accomplish the desired attributes.

摘要： Information regarding volume mount points hosted by a logical volume are stored on the physical device underlying the logical volume so that the relationships between the host logical volume and target logical volumes mounted on the volume mount points can be reconstituted when the system containing the logical volumes is rebooted, when the underlying physical devices are moved with the system, and when the logical volumes are transported to a different system. A data structure stored on the physical device contains the directory name of the volume mount point and the unique identifier and a globally unique mount name of the target logical volume mounted at the volume mount point. When the target logical volume is present in the system, symbolic links are created to relate the volume mount point name to a device name for the target logical volume so that pathnames containing the directory junction name are resolved correctly. If the target volume is not present in the system, the corresponding symbolic link does not exist, so an incorrect logical volume cannot be mounted onto a volume mount point. Furthermore, because the logical volumes contain the directory junction information, the namespace representing the logical volumes is self-describing so that neither user knowledge nor intervention is required to reconstitute the namespace.
摘要翻译：有关由逻辑卷托管的卷安装点的信息存储在逻辑卷底层的物理设备上，以便在包含逻辑卷的系统为包含逻辑卷的系统时，主机逻辑卷与安装在卷安装点上的目标逻辑卷之间的关系可以重新构建当底层物理设备与系统一起移动时，以及何时将逻辑卷传输到其他系统时重新启动。存储在物理设备上的数据结构包含卷安装点的目录名称和唯一标识符以及安装在卷安装点的目标逻辑卷的全局唯一安装名称。当系统中存在目标逻辑卷时，会创建符号链接，以将卷安装点名称与目标逻辑卷的设备名称相关联，以便正确解析包含目录结名的路径名。如果系统中不存在目标卷，则相应的符号链接不存在，因此不正确的逻辑卷无法挂载到卷安装点上。此外，由于逻辑卷包含目录结点信息，表示逻辑卷的命名空间是自描述的，因此不需要用户知识和干预来重构命名空间。

摘要： Persistent names for logical volumes in a computer system are used to enable symbolic links between the persistent names and non-persistent device names that identify the logical volumes to the lower layers of the operating system during a single boot session. A persistent unique mount name for each logical volume is associated with a unique volume identifier for the logical volume in a persistent mount manager data structure. Optionally a persistent drive letter can be assigned to the volume. Higher layers of the operating system and user applications address a volume through the persistent mount name as well as any assigned drive letter. When the system is rebooted, the data structure entries identified by the unique volume identifiers of the arriving logical volumes are used to reconstruct the symbolic links so that references to the persistent mount name, and optional drive letter, will resolve to the correct non-persistent device name, thus guaranteeing consistency in addressing the logical volumes across boot sessions. When the system undergoes physical reconfiguration, an existing persistent mount name is associated with 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, an in-memory data structure is created from the persistent data structure to increase the speed of the identification process.
摘要翻译：计算机系统中的逻辑卷的持久名称用于启用永久名称和非持久性设备名称之间的符号链接，以便在单个引导会话期间识别操作系统的较低层的逻辑卷。每个逻辑卷的持久唯一安装名称与持久性安装管理器数据结构中的逻辑卷的唯一卷标识符相关联。可选地，可以为卷分配持久性驱动器号。操作系统和用户应用程序的较高层通过持久安装名称以及任何分配的驱动器号来寻址卷。当系统重新启动时，由到达的逻辑卷的唯一卷标识符标识的数据结构条目用于重构符号链接，以便引用持久挂载名称和可选驱动器号可以解析为正确的非持久性设备名称，从而保证在引导会话中解决逻辑卷的一致性。当系统进行物理重新配置时，如果唯一卷标识符存在于数据结构中，则现有的持久性挂载名称与不同的非持久性设备名称相关联。以这种方式，可以在计算机中删除和恢复逻辑卷，而不需要知道较高层的操作系统和用户应用程序。可选地，从永久数据结构创建存储器内数据结构以增加识别过程的速度。
