适用场景

  • E 系列控制器固件 7.xx
  • E系列控制器固件8.xx

问题描述

有几种方法可用于检查是否已启用缓存;最简单的方法如下:

方法1:storage-array-profile

缓存设置会按卷进行报告、您可以在STORAGE-ARRAY-PROFILEE系列支持集合的""文件中的"标准卷"部分的"详细信息"部分下找到这些设置。

潜在状态:

Write cache:   Enabled
Write cache:   Disabled
Write cache:   Enabled   (currently suspended) <- Indicates controller suspended cache for some reason. Will need to be investigated.

 

请参见随附的示例 STORAGE-ARRAY-PROFILE.

方法2:状态捕获数据

缓存设置也可在STATE-CAPTURE-DATAccmShowStateCacheDeviceFlags""下的""中的""中找到:

潜在状态:

RCE = Read Cache Enabled
RCA = Read Cache Active
RCD = Read Cache Disabled
RCD = Read Cache Inactive
WCE = Write Cache Enabled
WCA = Write Cache Active
WCD = Write Cache Disabled
WCI = Write Cache Inactive
CME = Cache Mirroring Enabled
CMA = Cache Mirroring Active
CMD = Cache Mirroring Disabled
CMI = Cache Mirroring Inactive
WC_INTERNALLY_DISABLED  <- Indicates controller suspended cache for some reason. Will need to be investigated.
CM_INTERNALLY_DISABLED  <- Indicates controller suspended cache for some reason. Will need to be investigated.
