使用MegaCli查看raid信息

LSI SAS based MegaRAID driver

http://www.lsi.com/downloads/Public/Nytro/downloads/Nytro%20XD/MegaCli_Linux.zip

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.-.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-.so.14.07-

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: ×
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
#MegaCli -AdpBbuCmd -aAll
(7)查看命令帮助
#megacli -help
