如何确定 E 系列上是否启用了写入缓存
执行
执行
适用于
- E 系列控制器固件 7.xx
- E 系列控制器固件 8.xx
说明
有几种方法可以检查是否启用了缓存;最简单的方法如下所示:
方法 1 : storage-array-profile
缓存设置按卷报告,可以在STORAGE-ARRAY-PROFILE
E 系列支持集合的“”文件中的“标准卷”部分下找到。
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.
请参见附加示例 STORAGE-ARRAY-PROFILE.
方法 2 : state - capture-data
缓存设置也可以在“STATE-CAPTURE-DATA
”、“ccmShowState
”下的“CacheDeviceFlags
”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.
请参见附加示例STATE-CAPTURE-DATA
