操作系统自带的命令查看RAID：

软件raid：查看raid级别，状态等信息【生产环境没人敢用软raid，除非他不想干了】

# cat/proc/mdstat

硬件raid：查看raid的厂商，型号，级别

# dmesg |grep -i raid

# cat/proc/scsi/scsi

DELL服务器 使用MegaCli64查看RAID：

安装

# rpm-ivh MegaCli64-8.07.14-1.noarch.rpm

默认是安装到/opt/MegaRAID目录下了。

cd /opt/MegaRAID/MegaCli

执行./MegaCli64 -LDInfo -LAll-aAll  ---->常用

#./MegaCli64  -LDInfo -Lall -aALL查raid级别

#./MegaCli64-AdpAllInfo -aALL查raid卡信息

#./MegaCli64 -PDList -aALL查看硬盘信息---->常用

#./MegaCli64 -AdpBbuCmd -aAll查看电池信息

#./MegaCli64-FwTermLog -Dsply -aALL查看raid卡日志

#./MegaCli64-adpCount【显示适配器个数】

#./MegaCli64-AdpGetTime–aALL【显示适配器时间】

#./MegaCli64-AdpAllInfo -aAll【显示所有适配器信息】

#./MegaCli64-LDInfo -LALL -aAll【显示所有逻辑磁盘组信息】

#./MegaCli64-PDList -aAll【显示所有的物理信息】

#./MegaCli64-AdpBbuCmd -GetBbuStatus -aALL |grep 'Charger Status'【查看充电状态】

#./MegaCli64-AdpBbuCmd -GetBbuStatus -aALL【显示BBU状态信息】

#./MegaCli64-AdpBbuCmd -GetBbuCapacityInfo -aALL【显示BBU容量信息】

#./MegaCli64-AdpBbuCmd -GetBbuDesignInfo -aALL【显示BBU设计参数】

#./MegaCli64-AdpBbuCmd -GetBbuProperties -aALL【显示当前BBU属性】

#./MegaCli64-cfgdsply -aALL【显示Raid卡型号，Raid设置，Disk相关信息】

3.磁带状态的变化，从拔盘，到插盘的过程中。

Device        |Normal|Damage|Rebuild|Normal

VirtualDrive    |Optimal|Degraded|Degraded|Optimal

PhysicalDrive    |Online|Failed –>Unconfigured|Rebuild|Online

4.查看磁盘缓存策略

#./MegaCli64-LDGetProp -Cache -L0 -a0

or

#./MegaCli64-LDGetProp -Cache -L1 -a0

or

#./MegaCli64-LDGetProp -Cache -LALL -a0

ro

#./MegaCli64-LDGetProp -Cache -LALL -aALL

ro

#./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：

#./MegaCli64-LDSetProp WT|WB|NORA|RA|ADRA -L0 -a0

or

#./MegaCli64-LDSetProp -Cached|-Direct -L0 -a0

or

enable /disable disk cache

#./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

#./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

#./MegaCli64-CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -a0

8.删除阵列

#./MegaCli64-CfgLdDel -L1 -a0

9.在线添加磁盘

#./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。

#./MegaCli64-LDInit -ShowProg -LALL -aALL

或者以动态可视化文字界面显示

#./MegaCli64-LDInit -ProgDsply -LALL -aALL

11.查看阵列后台初始化进度

#./MegaCli64-LDBI -ShowProg -LALL -aALL

或者以动态可视化文字界面显示

#./MegaCli64-LDBI -ProgDsply -LALL -aALL

12.指定第5块盘作为全局热备

#./MegaCli64-PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0

13.指定为某个阵列的专用热备

#./MegaCli64-PDHSP -Set [-Dedicated [-Array1]] [-EnclAffinity] [-nonRevertible]-PhysDrv[1:5] -a0

14.删除全局热备

#./MegaCli64-PDHSP -Rmv -PhysDrv[1:5] -a0

15.将某块物理盘下线/上线

#./MegaCli64-PDOffline -PhysDrv [1:4] -a0

#./MegaCli64-PDOnline -PhysDrv [1:4] -a0

16.查看物理磁盘重建进度

#./MegaCli64-PDRbld -ShowProg -PhysDrv [1:5] -a0

或者以动态可视化文字界面显示

#./MegaCli64-PDRbld -ProgDsply -PhysDrv [1:5] -a0
