执行

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-PROFILE
E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-DATA
ccmShowState
CacheDeviceFlags
""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.
请参阅随附的示例 STATE-CAPTURE-DATA
