适用场景

  • ONTAP 9
  • FabricPool

问题解答

在一天运行散热扫描程序后添加了数据

 
示例:
 
  • 最小冷却天数设置为2
  • 策略设置为自动
  • 已达到填充度阈值
 
1 天:在扫描程序运行后移动数据。
2 天:扫描程序运行并发现数据。
3 天:扫描程序再次看到数据、但只冷却了1天。
第4 天:扫描程序发现数据已冷却2天并移动。
 
 
注意: 数据散热扫描程序每天仅运行一次
 

追加信息

要检查分层策略和散热天数、请执行以下操作:
 
cluster1::> volume show -volume <vol-name> -fields tiering-policy, tiering-minimum-cooling-days
 
要检查填充度阈值、请执行以下操作:
 
cluster1::> aggr object-store show -fields tiering-fullness-threshold
