摘要： Embodiments of the invention relate to handling failures in a cluster of computer resources. The resources are represented as nodes in a dependency graph in which some nodes are articulation points and the removal of any articulation point due to a resource failure results in a disconnected graph. The embodiments perform a failover when a resource corresponding to an articulation point fails. The failover is to a local resource if the failed resource does not affect all local resources. The failover is to a remote resource if no local resource can meet all resource requirements of the failed resource, and to a remote resource running in a degraded mode if the remote resource cannot meet all of the requirements.
摘要翻译：本发明的实施例涉及处理计算机资源群集中的故障。资源被表示为依赖图中的节点，其中一些节点是关节点，并且由于资源故障导致的任何关节点的移除导致断开的图形。当与关节点相对应的资源失效时，这些实施例执行故障切换。如果失败的资源不影响所有本地资源，则故障切换将是本地资源。如果没有本地资源可以满足故障资源的所有资源需求以及远程资源不能满足所有需求的远程资源，则该故障转移将是远程资源。

摘要： A method, system, and article are provided to enable a Hyperswap operation in a clustered computer system. Each node in the system is configured with flash memory, with a hierarchical list of boot volumes therein. Following a Hyperswap operation, the current boot volume is communicated to each node in the cluster and each node joining the cluster. All previously inactive nodes that were booted from the improper boot volume are re-booted from the correct and the flash memory is amended to reflect the correct boot volume.

摘要： A mechanism to permit consolidation of storage subsystem volumes into larger, more easily managed volumes and an operating system device driver which includes a trap mechanism for intercepting calls from a host into logical unit devices that were previously consolidated into a single physical volume. A map converts such calls to a logical unit device into a corresponding offset in the single physical volume. A driver accesses the single physical volume with corresponding offsets to transfer data associated with a particular logical unit device. So, logical unit devices can be consolidated and reconsolidated to single physical volumes and other physical volumes without requiring changes to the operating system or its application software and without requiring application or host downtime.
摘要翻译：一种允许将存储子系统卷整合到更大，更容易管理的卷中的机制，以及一种操作系统设备驱动程序，其包括用于拦截主机到先前合并到单个物理卷中的逻辑单元设备的呼叫的陷阱机制。地图将这样的呼叫转换为逻辑单元设备到单个物理卷中的相应偏移量。驾驶员使用相应的偏移量访问单个物理卷以传送与特定逻辑单元设备相关联的数据。因此，可以将逻辑单元设备整合并重新分解为单个物理卷和其他物理卷，而无需更改操作系统或其应用程序软件，并且不需要应用程序或主机停机。
