In this mode, the Shared volume groups are accessible by multiple PowerHA nodes, which results in faster failover (disk takeover) in the event of a node failure.
在这种模式下，多个Power ha节点都可以访问共享卷组，这会加快发生节点故障时的故障转移(磁盘接管)。
You should now have all the components necessary to handle a failure of the master node, if it should occur.
现在您就已经拥有了处理主节点故障(如果它会发生)所需要的所有组成部分。
For the second failure, case 1: If a fails, it is placed on the spare node.
对于第二次故障，情形1：如果A出现故障，它将被转移到空闲节点上。
