事件摘要

CallHome.spares事件 

如果一个或多个RAID组没有符合条件的备用磁盘驱动器、则会在磁盘驱动器发生故障时显示此消息。 

  • 符合条件的备用磁盘驱动器必须具有正确的大小和容量、并且必须位于相应的池中。
    • 如果磁盘驱动器发生故障、并且没有可重建的备用磁盘、则系统将进入降级模式。

"降级"的定义 取决于聚合使用的RAID组类型:

  • RAID4 - RAID组有一个磁盘缺失或出现故障
  • RAID-DP —RAID组有两个缺失磁盘或发生故障的磁盘
  • RAID-TEC - RAID组有三个缺失磁盘或发生故障的磁盘
  •  如果镜像聚合的两个plexes在同一定位RAID组中缺少磁盘或发生故障磁盘、则该聚合将被视为"已降级"。
  • 在9.12.1之前的ONTAP版本中,如果系统在完全降级模式下按定义的超时时间间隔运行,则会自动暂停以防止RAID组完整性故障和可能的数据丢失。
    • 默认超时为24小时。
  • 如果在系统以降级模式运行时备用驱动器可用、则系统会立即开始重建故障驱动器。
