lsi官网下载最新MegaCli。
解压有两个文件MegaCli-8.07.08-1.noarch.rpm，megacli_8.07.08-1_all.deb
我们用的是centos，用如下命令安装
rpm -ivh MegaCli-8.07.08-1.noarch.rpm
确认安装信息
[root@xxxx ~]# rpm -ql MegaCli /opt/MegaRAID/MegaCli/MegaCli /opt/MegaRAID/MegaCli/MegaCli64 /opt/MegaRAID/MegaCli/libstorelibir-2.so.14.07-0
因为安装的是64bit操作系统，所以使用MegaCli64命令。
#/opt/MegaRAID/MegaCli/MegaCli64 该命令直接执行会提示如下错误 Fatal error – Command Tool invoked with wrong parameters Exit Code: 0×01 为这个命令做个软连接: #ln -sf /opt/MegaRAID/MegaCli/MegaCli64 /usr/bin/megacli
4. MegaCli常用命令：
(1)显示所有RAID级别、设置及逻辑盘信息
#megacli -LdInfo -LALL -aAll
(2)显示Raid卡型号,Raid设置,磁盘相关信息
#megacli -cfgdsply -aALL | more
(3)查看RAID卡详细信息
#MegaCli -AdpAllInfo -aALL
(4)查看适配器个数
#megacli -adpCount
(5)查看逻辑盘个数
#megacli -LdGetNum -aALL
(6)查看电池信息
