新版本的 MegaCli-1.01.24-0.i386.rpm (下载地址:http://www.lsi.com/Pages/user/eula.aspx?file=http%3a%2f%2fwww.lsi.com%2fdownloads%2fPublic%2fMegaRAID%2520Common%2520Files%2f8.00.46_Linux_MegaCLI.zip&Source=http%3a%2f%2fblog.chinaunix.net%2fuid-28705339-id-3760426.html)该包会把程序安装在/opt下,当然也可以自定义安装目录,例如:rpm--relocate /opt/=/usr/sbin/ -i MegaCli-1.01.24-0.i386.rpm (即把安装目录 /opt 替换成/usr/sbin)。
(linux文件夹下有个MegaCli文件里面有I386RPM)64位环境的话,是MegeCli64命令

硬盘方面:
1、查看所有物理磁盘信息
MegaCli -PDList-aALL

Media Error Count:0
Other Error Count:0
Predictive FailureCount: 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: DiskWrite Cache : Disk's Default
Adapter 0-VD 1: DiskWrite 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 readahead)
RA (Read ahead)
ADRA (Adaptiveread ahead)
Cached
Direct
例子:
MegaCli -LDSetPropWT|WB|NORA|RA|ADRA -L0 -a0
or
MegaCli -LDSetProp-Cached|-Direct -L0 -a0
or
enable / disabledisk 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] –a0
4.2 创建阵列,不指定热备
MegaCli -CfgLdAdd-r5 [1:2,1:3,1:4] WB Direct –a0
4.3 删除阵列
MegaCli -CfgLdDel-L1 –a0
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 –aALL
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
