监控 SnapVault 关系

应定期监控 SnapVault 关系的状态，确保按指定的计划在目标卷上备份数据。

关于本任务

snapmirror show 命令显示与 SnapMirror 和 SnapVault 关系相关联的信息。默认情况下，此命令显示以下信息：

  • 源路径

  • 关系类型

  • 目标路径

  • 镜像状态

  • 关系状态

  • 整体进度

  • 运行状况良好

  • 最近更新的进度

在“详细信息”按钮选项卡中验证状态。

此处将显示 SnapVault 关系的运行状况状态、任何传输错误和滞后时间：

  • “运行状况良好”字段必须显示 Yes。

    对于大多数数据传输失败的情况，此字段显示 No。但是在某些失败情况下，该字段仍然显示 Yes。必须检查“详细信息”部分中的传输错误以确保没有发生数据传输失败。

  • “关系状态”字段必须显示 Snapmirrored。

  • “滞后时间”不得超过传输计划时间间隔。

    例如，如果传输计划为每日，则滞后时间不得超过一天。
