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.
