二、常用命令

查看硬盘当前状态：

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aAll|egrep  "Adapter|Enclosure Device ID|Slot Number|Foreign State:"  

清除外来设备:

/opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -clear -a0   （在线更换硬盘或者增加硬盘后需要操作）

创建raid方法：

raid 0:

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r0 [32:5,32:6,32:7,32:8,32:9] WB Direct -a0

raid 1:

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r1 [32:4,32:5] WB Direct -a0

raid5:

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [32:2,32:3,32:4,32:5,32:6,32:7] WB Direct -a0

raid 6:

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r6 [32:2,32:3,32:4,32:5] WB Direct -a0    

raid 10:

/opt/MegaRAID/MegaCli/MegaCli64 -CfgSpanAdd -r10 -Array0[32:2,32:3] -Array1[32:4,32:5] -Array2[32:6,32:7] WB Direct -a0

raid5 + 热备盘

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [32:2,32:3,32:4] WB Direct -Hsp[32:5] -a0

删除raid:

/opt/MegaRAID/MegaCli/MegaCli64  -cfglddel  -L1 -force -a0

查看所有硬盘详细信息：

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL 

查看所有raid信息：

/opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -LALL -aAll 

查看硬盘物理状态：

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL |grep "Firmware state" 

外部设备导入raid信息：

/opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -import -a0

修改硬盘模式为unconfigure good：

/opt/MegaRAID/MegaCli/MegaCli64 -PDMakeGood -PhysDrv[32:4] -force -a0  

显示硬盘重建进度：

/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv [32:1] -a0  

查看日志：

/opt/MegaRAID/MegaCli/MegaCli64 -FwTermLog dsply -a0

查看raid卡电池状态：

/opt/MegaRAID/MegaCli/MegaCli64 -adpallinfo -a0|grep -i bbu

查看raid卡的信息：

/opt/MegaRAID/MegaCli/MegaCli64 -AdpAllInfo -aALL

查看磁盘缓存策略：

/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache -LALL -aALL

设置磁盘缓存策略：

缓存策略解释：

WT (Write through
WB (Write back)
NORA (No read ahead)
RA (Read ahead)
ADRA (Adaptive read ahead)
Cached
Direct
例子：
#/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp WT|WB|NORA|RA|ADRA -L0 -a0
or
#/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp -Cached|-Direct -L0 -a0
or
enable / disable disk cache
#/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp -EnDskCache|-DisDskCache -L0 -a0
