Instructions

您可能需要创建包含多个规则的快照计划，例如：

  1. 我们保留 24 小时的每小时检查点
  2. 我们保留 7 天的夜间检查点
  3. 每周检查点，保留 4 周

但是，您无法使用 UI 执行此作，因为 UI 允许每个计划最多两个规则。
创建计划

#> uemcli -no /sys/task/sched -id snapSch_19 show
1:    ID    = snapSch_19
      Name  = MySchedule
      Type  = User
      Rules = SchedRule_93, SchedRule_94

#> uemcli -no /sys/task/rule -id SchedRule_93 show
1:    ID                = SchedRule_93
      Type              = HoursInterval
      Frequency         = Every 1h
      Keep for          = 1d
      Allow auto-delete = no
      Access            = Checkpoint

#> uemcli -no /sys/task/rule -id SchedRule_94 show
1:    ID                = SchedRule_94
      Type              = WeekDaysList
      Frequency         = Every Mon, Tue, Wed, Thu, Fri, Sat, Sun at 00:00
      Keep for          = 7d
      Allow auto-delete = no
      Access            = Checkpoint

并且最多可以为 LUN 分配一个计划，因此您无法满足要求。

但是，您可以使用 CLI 满足要求，因此在我们的示例中，我们使用 UI 创建了包含前两条规则的快照计划 （snapSch_19），然后通过以下命令使用 CLI 将第三条规则添加到计划中：

#> uemcli -no -u <username> -p <password> /sys/task/rule create -schedId snapSch_19 -type weekdayslist -days sat -at 12:00 -keepFor 31d -access ckpt

结果如下，符合我们的要求：

#> uemcli -no /sys/task/sched -id snapSch_19 show
1:    ID    = snapSch_19
      Name  = MySchedule
      Type  = User
      Rules = SchedRule_93, SchedRule_94, SchedRule_95

#> uemcli -no /sys/task/rule -id SchedRule_93 show
1:    ID                = SchedRule_93
      Type              = HoursInterval
      Frequency         = Every 1h
      Keep for          = 1d
      Allow auto-delete = no
      Access            = Checkpoint

#> uemcli -no /sys/task/rule -id SchedRule_94 show
1:    ID                = SchedRule_94
      Type              = WeekDaysList
      Frequency         = Every Mon, Tue, Wed, Thu, Fri, Sat, Sun at 00:00
      Keep for          = 7d
      Allow auto-delete = no
      Access            = Checkpoint

#> uemcli -no /sys/task/rule -id SchedRule_95 show
1:    ID                = SchedRule_95
      Type              = WeekDaysList
      Frequency         = Every Sat at 12:00
      Keep for          = 31d
      Allow auto-delete = no
      Access            = Checkpoint

我还能够在同一计划中添加更多规则，但 UI 仍然只能显示前两个规则！
