PowerScale OneFS 9.X.X：Resolved: 启用以下位置的驱动器的写入高速缓存

Summary: 在一个或多个节点重新启动后，用户可能会看到一个或多个节点的以下错误或类似内容。OneFS 禁用了写入高速缓存，以符合建议的驱动器设置。“已解决：启用以下位置的驱动器的写入高速缓存：机箱序列号JXXXXXXXXXXXX1、节点 4、底座 E、插槽 1、类型 HDD、LNUM 0、串行 XXXXXXXX。”

Symptoms

更改是节点重新启动。对于所有驱动器，您可能不会看到此消息，可能整个群集中只有一个或两个驱动器。

用户会看到以下警报或类似内容，并想知道导致该问题的原因以及驱动器是否损坏： 
Resolved: The write-cache for the drive in the following location is enabled: Chassis Serial Number JXXXXXXXXXXXX1, Node 4, Sled E, Slot 1, Type HDD, LNUM 0, Serial XXXXXXXX. OneFS disabled the write-cache to comply with recommended drive settings. Replace the drive according to the instructions in the H400 Drive Replacement Guide.

提醒：这仅在第 6 代群集上出现。

Cause

该问题是，默认情况下，驱动器上的写入高速缓存处于禁用状态，并且在重新启动期间，写入高速缓存似乎已更改为已启用。系统报告此信息通常是表面性质的，可在检查“Write Cache Enabled”值时忽略。

这将在未来的 OneFS 版本中得到解决。戴尔工程团队正在努力更改事件通知。

Resolution

运行以下命令以确认驱动器的状态以及驱动器写入高速缓存已禁用：     
  1. 验证驱动器的状态，并检查是否有任何不正常运行的驱动器：       
# isi_for_array 'isi devices list | grep -iv "healthy" | grep -iv "L3"
  1. 检查驱动器的写入高速缓存是否已禁用：       
# camcontrol modepage da<drive da number> -m 8 -P 0
# camcontrol modepage da<drive da number>-m 8 -P 1
# camcontrol modepage da<drive da number>-m 8 -P 2
# camcontrol modepage da<drive da number>-m 8 -P 3

上述每个命令都显示值列表，如下所示：  
Cluster-8# isi_for_array -n4 camcontrol modepage da3 -m 8 -P 0
Cluster-4: IC: 0
Cluster-4: ABPF: 0
