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 [1:4] -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

Virtual Drive |Optimal|Degraded|Degraded|Optimal

Physical Drive |Online|Failed –> Unconfigured|Rebuild|Online
