检查 MetroCluster 配置

您可以检查 MetroCluster 配置中的组件和关系是否运行正常。在初始配置完成后以及在对 MetroCluster 配置做出任何更改后,都应该执行一次检查。您还应在执行协商(计划内)切换或切回操作之前执行一次检查。

关于本任务

如果在任一集群或同时在两个集群上短时间发出两次 metrocluster check run 命令,则可能发生冲突,并且此命令可能不会收集所有数据。如果此后再发出 metrocluster check show 命令,则不会显示应有的输出。

步骤

  1. 检查配置:metrocluster check run
    示例
    此命令会作为后台作业运行,并且可能无法立即完成。
    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

    Component           Result
    ------------------- ---------
    nodes               ok
    lifs                ok
    config-replication  ok
    aggregates          ok
    clusters            ok
    5 entries were displayed.
    
    
  2. 显示最近一次运行 metrocluster check run 命令后输出的详细结果:metrocluster check aggregate showmetrocluster check cluster showmetrocluster check config-replication showmetrocluster check lif showmetrocluster check node show
    metrocluster check show 命令可显示最近一次运行 metrocluster check run 命令的结果。应始终先运行 metrocluster check run 命令,再运行 metrocluster check show 命令,以便显示的信息为最新状态。
    示例
    以下示例显示了一个运行正常的四节点 MetroCluster 配置的 metrocluster check aggregate show 命令输出:
    cluster_A::> metrocluster check aggregate show
