适用场景

  • ONTAP 9
  • 使用16个或更少驱动器的AFF / FAS系统

问题描述

默认情况下、如果与存储系统中每个驱动器的属性匹配的热备用驱动器数量少于一个、则系统会向控制台发出警告并记录这些警告。

  • RAID.min_spare_count选项指定为避免出现有关备用驱动器不足的警告所需的最小备用驱动器数。
  • 如果每种类型的驱动器都具有在raid.min_spare_count 中指定的最少量备用驱动器、并且这些驱动器是合适的替换驱动器、则不会针对备用磁盘不足显示任何警告。

已设置 raid.min_spare_count

  • 指定为避免出现有关备用驱动器不足的警告而需要的最小备用驱动器数。
  • 可以设置为0到4。
  • 默认设置
    • 对于容量优化型平台(例如AFF C190)、为0。
    • 1用于其他平台(例如FAS2720)。

设置为0

  • 将此选项设置为0意味着、即使没有可用的备用磁盘、也会针对低备用磁盘显示任何警告
  • 仅在连接了16个或更少驱动器且具有RAID-DP聚合的独立系统或HA系统上允许。
限制 

 

自动更改

  • 如果非容量优化系统在 raid.min_spare_count  设置为0的情况下扩展到16个以上的驱动器、则此选项将自动改回1。

限制

  • 使用RAID4聚合的系统不允许设置为0。
