Abstract: A system and method for handling multi-node failures in a disaster recovery cluster is provided. In the event of an error condition, a switchover operation occurs from the failed nodes to one or more surviving nodes. Data stored in non-volatile random access memory is recovered by the surviving nodes to bring storage objects, e.g., disks, aggregates and/or volumes into a consistent state.

Abstract translation: 提供了一种用于处理灾难恢复群集中的多节点故障的系统和方法。 在发生错误情况时，从发生故障的节点到一个或多个幸存节点发生切换操作。 存储在非易失性随机存取存储器中的数据由幸存的节点恢复，以使存储对象（例如磁盘，聚合体和/或卷）进入一致状态。
