Storage system with mainframe and open host performing remote copying by setting a copy group
摘要：
If the pair state of a certain volume pair in one copy group is a fault state which has changed due to occurrence of a fault in the volume pair, then a write holding state is set for the copy group, and after setting the write holding state, the pair states of all the other volume pairs belonging to the copy group are set to a copy halt state. When setting the write holding state, and when executing setting of the copy halt setting state, commands from an open host are not necessary.
摘要（中）：

如果一个拷贝组中某个卷对的配对状态是由于卷对中发生故障而发生变化的故障状态，则为复制组设置写保持状态，并且在设置写保持状态 属于复制组的所有其他卷对的对状态被设置为复制停止状态。 当设置写入保持状态时，当执行复制停止设置状态的设置时，不需要来自打开的主机的命令。
