1、简介
MegaCli 是LSI公司官方提供的SCSI卡管理工具，由于LSI被收购变成了现在的Broadcom，所以现在想下载MegaCli，
需要去Broadcom官网查找Legacy产品支持，搜索MegaRAID即可。
现在官方有storcli，storcli已经基本代替了megacli，整合了LSI和3ware所有产品。
安装方面比较简单，megacli还要Lib_Utils的支持，而storcli只用一个rpm包就可以下载，
去Broadcom官网去找就行了：https://www.broadcom.com/site-search?q=storcli
storcli支持json格式输出，信息解析更加方便。
我个人推荐使用这个软件，因为megacli 工具需要安装额外的软件包，有些服务器客户不允许安装其他的软件包，所以比较麻烦。
这个工具直接安装了之后就可以用。
1.1服务器信息：
1.2系统信息：
[root@localhost storcli]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)
1.3 安装storcli
rpm -ivh storcli-1.03.11-1.noarch.rpm
目录： /opt/Mega/storcli
注意版本问题
我这台服务器是DELL R720xd，2012年上线的，所以我用的是storcli.1.03.11版本。
我用的新版本安装之后，执行命令没有输出，所以这一点需要注意。
1.4一些参数定义：
/cx = Controller ID
/vx = Virtual Drive Number.
/ex = Enclosure ID
/sx = Slot ID
1.5为了管理方便，建立软连接
ln -s /opt/MegaRAID/storcli/storcli64 /bin/storcli
ln -s /opt/MegaRAID/storcli/storcli64 /sbin/storcli
如果不想建立软连接，就在/opt/MegaRAID/storcli 目录下 执行./storcli64 指令
2、查看当前设备raid控制器相关信息
[root@localhost storcli]# ./storcli64 show all 可以看到只有一个控制器
Status Code = 0
