适用于

Data ONTAP 7 及更早版本 

说明

如果这会影响您的系统、请检查 Active IQ 的输出中显示的多个磁盘。

prefailsysconfig -r.sysconfig -r输出可能与多个磁盘上的输出类似:

data         2a.18        2a 1 2 FC:A - FCAL 10000 136000/278528000 137104/280790184 (prefail)

系统会继续在这些预故障磁盘上提供数据、但会在备用磁盘可用时将其复制到备用磁盘。如果已预先确定出现故障的磁盘数超过可用备用磁盘数,则备用磁盘池将耗尽,并且系统将开始记录备用磁盘不足警告。
