检查 MetroCluster 配置
可以检查 MetroCluster 配置中的组件和关系是否正常工作。应该在初始配置之后以及对 MetroCluster 配置进行任何更改后进行检查。还应该在协商（计划内）切换或切回操作之前进行检查。
关于本任务
如果在一个或两个集群上短时间内发出两次 metrocluster check run 命令，可能会发生冲突，该命令可能无法收集所有数据。后续的 metrocluster check show 命令不会显示预期的输出。
- 检查配置：metrocluster check run
示例
该命令作为后台作业运行，可能不会立即完成。
cluster_A::> metrocluster check run
The operation has been started and is running in the background. Wait for
it to complete and run "metrocluster check show" to view the results. To
check the status of the running metrocluster check operation, use the command,
"metrocluster operation history show -job-id 2245"cluster_A::> metrocluster check show

6 entries were displayed. - 显示最近一次 metrocluster check run 命令的更详细结果：metrocluster check aggregate show metrocluster check cluster show metrocluster check config-replication show metrocluster check lif show metrocluster check node show
metrocluster check show 命令显示最近一次 metrocluster check run 命令的结果。在使用 metrocluster check show 命令之前，应始终运行 metrocluster check run 命令，使显示的信息是最新信息。
示例
以下示例显示了正常运行的四节点 MetroCluster 配置的 metrocluster check aggregate show 命令输出：
cluster_A::> metrocluster check aggregate show
