事件摘要

callhome.spares 事件 

如果一个或多个 RAID 组在发生磁盘驱动器故障时没有合格的备用磁盘驱动器可用,则会出现此消息。 

  • 符合条件的备用磁盘驱动器必须具有正确的大小和容量,并且必须位于适当的池中。
    • 如果磁盘驱动器在没有备用磁盘的情况下发生故障,则系统将进入降级模式。

"降级"的定义 "降级" 取决于聚合使用的 RAID 组类型:

  • raid4  - RAID 组有一个丢失或故障的磁盘
  • raid-dp  - RAID 组有两个丢失或故障的磁盘
  • raid-tec  - RAID 组有三个丢失或故障的磁盘
  • 如果聚合的两个丛在同一位置 RAID 组中都有丢失或故障的磁盘,则镜像聚合被视为 "降级" 。
  • 在早于 9.12.1 的 ONTAP 版本中,如果系统在定义的超时间隔内以完全降级模式运行,则系统会自动停止以防止 RAID 组完整性故障和可能的数据丢失。
    • 默认超时时间为 24 小时。
  • 如果系统在降级模式下运行时备用驱动器可用,系统会立即开始重建出现故障的驱动器。
