硬盘方面：
1、查看所有物理磁盘信息
MegaCli -PDList -aALL
Adapter #0
Enclosure Number: 1
Slot Number: 5
Device Id: 5
Sequence Number: 2
Media Error Count: 0
Other Error Count: 0

.....
2、查看磁盘缓存策略
MegaCli -LDGetProp -Cache -L0 -a0
Adapter 0-VD 0: Cache Policy:WriteBack, ReadAheadNone, Direct
or
MegaCli -LDGetProp -Cache -L1 -a0
Adapter 0-VD 1: Cache Policy:WriteBack, ReadAheadNone, Direct
or
MegaCli -LDGetProp -Cache -LALL -a0
Adapter 0-VD 0: Cache Policy:WriteBack, ReadAheadNone, Direct
Adapter 0-VD 1: Cache Policy:WriteBack, ReadAheadNone, Direct
or
MegaCli -LDGetProp -Cache -LALL -aALL
Adapter 0-VD 0: Cache Policy:WriteBack, ReadAheadNone, Direct
Adapter 0-VD 1: Cache Policy:WriteBack, ReadAheadNone, Direct
or
MegaCli -LDGetProp -DskCache -LALL -aALL
Adapter 0-VD 0: Disk Write Cache : Disk's Default
Adapter 0-VD 1: Disk Write Cache : Disk's Default
3、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：
MegaCli -LDSetProp WT|WB|NORA|RA|ADRA -L0 -a0
or
MegaCli -LDSetProp -Cached|-Direct -L0 -a0
or
enable / disable disk cache
MegaCli -LDSetProp -EnDskCache|-DisDskCache -L0 -a0
4、创建/删除 阵列
4.1 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
MegaCli -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -Hsp[1:5] �Ca0
4.2 创建阵列，不指定热备
MegaCli -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct �Ca0
4.3 删除阵列
MegaCli -CfgLdDel -L1 �Ca0
4.4 在线添加磁盘
MegaCli -LDRecon -Start -r5 -Add -PhysDrv[1:4] -L1 -a0
意思是，重建逻辑磁盘组1，raid级别是5，添加物理磁盘号：1:4。重建完后，新添加的物理磁盘会自动处于重建(同步)状态，这个 时候 fdisk -l是看不到阵列的空间变大的，只有在系统重启后才能看见。
5、查看阵列初始化信息
5.1 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。
MegaCli -LDInit -ShowProg -LALL -aALL
或者以动态可视化文字界面显示
MegaCli -LDInit -ProgDsply -LALL �CaALL
5.2 查看阵列后台初始化进度
MegaCli -LDBI -ShowProg -LALL -aALL
或者以动态可视化文字界面显示
MegaCli -LDBI -ProgDsply -LALL -aALL
6、创建全局热备
指定第 5 块盘作为全局热备
MegaCli -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
也可以指定为某个阵列的专用热备
MegaCli -PDHSP -Set [-Dedicated [-Array1]] [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
7、删除全局热备
MegaCli -PDHSP -Rmv -PhysDrv[1:5] -a0
8、将某块物理盘下线/上线
MegaCli -PDOffline -PhysDrv [1:4] -a0
MegaCli -PDOnline -PhysDrv [1:4] -a0
9、查看物理磁盘重建进度
MegaCli -PDRbld -ShowProg -PhysDrv [1:5] -a0
