如果这些机器中的一台出了故障，那么保持商业操作所需要的资源会转移到群集中另一台可用机器上。
If one of those machines should fail, the resources required to maintain business operations are transferred to another available machine in the cluster.
当出现一个高可用性事件时，这个资源组将故障转移到辅助计算机上，从停止的地方继续进行处理。
When a high availability event occurs, this resource group will fail over to the secondary machine and continue processing where it left off.
灾难恢复和高可用性故障转移要求跨所有节点惟一地标识这些过程中涉及的资源。
Disaster recovery and high availability fail-overs require that resources involved in these processes be uniquely identified across all nodes.
通过数据库管理的空间(DMS)和原始设备，我们可以减少磁盘资源的故障转移时间，因为在故障转移时将不会进行磁盘检查。
With database managed space (DMS) and raw device, we can decrease the time to fail over the disk resources, because there will be no checking of disks during failover.
发生故障或者服务器从故障中恢复之后，它按需处理从一个系统到另一个的资源组的故障转移。
It handles the failing over of the resource groups from one system to the other as needed after a failure or after a coming back of a server from a failure.
通过用ewu值定义这些资源，可以在自动或手工故障转移、高可用性操作和灾难恢复测试或实现期间消除冲突。
Designing these resources with EWU values eliminates the possibility of conflict during automated or manual fail-overs, high-availability operations, and disaster-recovery testing or implementation.
此外，现在可以对单独的应用程序甚至单个资源进行故障转移，而以前的故障转移单位是整个队列管理器。
In addition, it is now possible to failover individual applications or even single resources, whereas previously the unit of failover was an entire queue manager.
如果没有在峰值负载下积极测试和验证集群，那么在真正发生故障时，故障转移的一端可能受到资源限制，响应时间较长，甚至出现故障。
If you do not actively test and validate your clustering during peak loads, during an actual failure the failover side can become constrained and deliver poor response times or even fail.
发生故障转移的情况有两种：一是系统管理员指示集群中的节点执行故障转移；二是出现灾难性应用程序或服务器故障的情况迫使资源组转移。
Failover can occur when a systems administrator instructs the nodes in the cluster to do so or when circumstances like a catastrophic application or server failure forces the resource groups to move.
故障恢复/回退：这是在故障转移发生后将资源组移回其最初在其上运行的原始节点的操作。
Failback/fallback: This is the action of moving back resource groups to the nodes on which they were originally running after a failover has occurred.
在资源组中，我们定义了将挂到需要进行故障转移的DB 2UDB服务器的所有资源。
In a resource group we define all resources that should be attached to the DB2 UDB server that we want to failover.
HACMP还必须对所有其他资源(如网络适配器)进行故障转移，但是，将会最小化时间最长的磁盘故障转移。
HACMP will still have to fail over all other resources (like the network adapters), but the disk failover, which is the longest, will be minimized.
此外，成对的故障转移节点允许节点和所有的资源(包括MQ)作为一个单元转移到被动机上。
Additionally, the pairing of the failover node allows for the node and all of its resources, including MQ, to fail over as a single unit to the passive machine.
在企业范围内对资源进行唯一地命名，这样可以提供一种有效的方法，以便在灾难恢复或者高可用性故障转移的过程中避免发生冲突。
The unique naming methodology for resources across the enterprise provides an effective method of avoiding conflicts during a disaster recovery or high-availability failover.
因此，系统要么变得不一致，要么完全停止，直到对某些共享资源进行了故障转移(仅转移到一个数据中心)。
Thus, the system will either become inconsistent or simply stop until the failover (to only one data center) of some Shared resource.
开发人员必须熟悉和使用配置的SIBus资源，而且在MQLink支持的故障转移的配置上还存在一些限制。
The developer must be familiar with and use the SIBus resources for the configuration, plus there are limitations on the configurations for failover which are supported by MQLink.
资源组（Resourcegroup）：这是一组需要从一台服务器进行故障转移至另一台的全部资源。
Resource group: This is a group of all resources that need to be failed over from one server to the other.
资源组（Resourcegroup）：这是一组需要从一台服务器进行故障转移至另一台的全部资源。
Resource group: This is a group of all resources that need to be failed over from one server to the other.
