3.磁带状态的变化，从拔盘，到插盘的过程中。
Device |Normal|Damage|Rebuild|Normal
Virtual Drive |Optimal|Degraded|Degraded|Optimal
Physical Drive |Online|Failed –> Unconfigured|Rebuild|Online
4.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
5.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
6.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
7.创建阵列，不指定热备
#/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -a0
8.删除阵列
#/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdDel -L1 -a0
9.在线添加磁盘
#/opt/MegaRAID/MegaCli/MegaCli64 -LDRecon -Start -r5 -Add -PhysDrv[1:4] -L1 -a0
10.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
11.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
12.指定第 5 块盘作为全局热备
#/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
13.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
14.删除全局热备
#/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Rmv -PhysDrv[1:5] -a0
15.将某块物理盘下线/上线
#/opt/MegaRAID/MegaCli/MegaCli64 -PDOffline -PhysDrv [32:4] -a0
#/opt/MegaRAID/MegaCli/MegaCli64 -PDOnline -PhysDrv [1:4] -a0
16.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
磁带状态的变化，从拔盘，到插盘的过程中：
Device |Normal|Damage|Rebuild|Normal
