以下示例显示发生群集间链路中断时使用 /clusters/cluster-name/ consistency-groups/consistency-group 上下文
中的 ls 命令时的输出。
● detach-rule 是 no-automatic-winner，因此 I/O 会在两个群集中停止。在群集间链路重新启动，或者您使用
consistency-group choose-winner 命令进行干预之前，Metro Node 会一直保持该状态。
● 状态 summary 为 suspended，表明 I/O 已停止。
● 状态 details 包含 cluster-departure，指示群集不能再彼此通信。
VPlexcli:/clusters/cluster-1/consistency-groups/cg1> ls

● 在声明 cluster-2 是群集间链路中断期间丢失的群集后，ls 命令会将一致性组 cg1 显示为在 cluster-2 上已暂停，requires-
resume-at-loser。
● resume-at-loser 命令会重新启动 cluster-2 上的 I/O。
● ls 命令显示操作状态的更改：

This may change the view of data presented to applications at cluster cluster-2. You
should first stop applications at that cluster. Continue? (Yes/No) Yes
