查看磁盘缓存策略
/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache -L0 -a0
or
/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache -L1 -a0
or
/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache -LALL -a0
ro
/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache -LALL -aALL
ro
/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -DskCache -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
创建一个 raid5 阵列，由物理盘 2,3,4 构成，该阵列的热备盘是物理盘 5
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -Hsp[1:5] -a0
创建阵列，不指定热备
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -a0
删除阵列
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdDel -L1 -a0
在线添加磁盘
/opt/MegaRAID/MegaCli/MegaCli64 -LDRecon -Start -r5 -Add -PhysDrv[1:4] -L1 -a0
阵列创建完后，会有一个初始化同步块的过程，可以看看其进度。
/opt/MegaRAID/MegaCli/MegaCli64 -LDInit -ShowProg -LALL -aALL
或者以动态可视化文字界面显示
/opt/MegaRAID/MegaCli/MegaCli64 -LDInit -ProgDsply -LALL -aALL
查看阵列后台初始化进度
/opt/MegaRAID/MegaCli/MegaCli64 -LDBI -ShowProg -LALL -aALL
或者以动态可视化文字界面显示
/opt/MegaRAID/MegaCli/MegaCli64 -LDBI -ProgDsply -LALL -aALL
指定第 5 块盘作为全局热备
/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
指定为某个阵列的专用热备
/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Set [-Dedicated [-Array1]] [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
删除全局热备
/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Rmv -PhysDrv[1:5] -a0
将某块物理盘下线/上线
/opt/MegaRAID/MegaCli/MegaCli64 -PDOffline -PhysDrv [1:4] -a0
/opt/MegaRAID/MegaCli/MegaCli64 -PDOnline -PhysDrv [1:4] -a0
查看物理磁盘重建进度
/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv [1:5] -a0
或者以动态可视化文字界面显示
/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ProgDsply -PhysDrv [1:5] -a0
