Physical Drive83. 1、查看RAID级别84. 85. 2、查看RAID卡信息，主要输出RAID卡的一些配置信息86. 87. 88. RAID Level : Primary-1, Secondary-0, RAID L

8、evel Qualifier-0Size : 1.086 TBState : OptimalStrip Size : 128 KBNumber Of Drives per span:4 /表示每4个物理盘做成一个RAID1盘组Span Depth : 2 /表示共2个RAID1盘组做成了RAID1089. 90. 3、查看所有硬盘的信息91. /opt/MegaCli64-pdlistaALL92. 93. 4、查看当前raid缓存状态，raid缓存状态设置为wb的话要注意电池放电事宜，设置电池放电模式为自动学习模式94. /opt/MegaRAID/MegaCli/MegaCli64 -ld

9、getprop -dskcache -lall -aall95. 96. 5、raid电池设置相关97. 查看电池状态信息（DisplayBBUStatusInformation）MegaCli-aN|-a0,1,2|-aALL98. 查看电池容量（DisplayCapacity99. 查看电池设计参数（DisplayDesignParameters）100. 查看电池属性（DisplayCurrentProperties）101. 设置电池为学习模式为循环模式（StartLearningCycle）DescriptionStartsthelearningcycleonBBU.Noparame

10、terisneededforthisoption.-BbuLearn102. 设置磁盘的缓存模式和访问方式（ChangeVirtualDiskCacheandAccessAllowsyoutochangefollowingvirtualdiskparameters:-WT（Writethrough）,WBback）:Selectswritepolicy.-NORA（Noreadahead）,RA（ReadADRA（Adaptiveahead）:-Cached,-Direct:cache-RW,-RO,Blocked:access-EnDskCache:Enablescache.-DisDskC

Megaraid 必知必会 使用LSI的megaraid可以对raid进行有效监控。别的厂商比如HP,IBM也有自己的raid API

12、MegaCli -ldinfo -lall -aall查询raid级别，磁盘数量，容量，条带大小。MegaCli -cfgdsply -aALL |grep Policy查询控制器cache策略MegaCli -LDSetProp WB -L0 -a0设置write back功能MegaCli -LDSetProp CachedBadBBU -L0 -a0设置即使电池坏了还是保持WB功能MegaCli -AdpBbuCmd -BbuLearn a0手动充电MegaCli -FwTermLog -Dsply -aALL查询日志显示适配器个数： MegaCli -adpCount显示所有适配器信息
