一、簡介
MegaCli 是LSI公司官方提供的SCSI卡管理工具，因爲LSI被收購變成了如今的Broadcom，因此如今想下載MegaCli，
須要去Broadcom官網查找Legacy產品支持，搜索MegaRAID便可。
如今官方有storcli，storcli已經基本代替了megacli，整合了LSI和3ware全部產品。
安裝方面比較簡單，megacli還要Lib_Utils的支持，而storcli只用一個rpm包就能夠下載，
去Broadcom官網去找就好了：
https://www.broadcom.com/site-search?q=storcli
storcli支持json格式輸出，信息解析更加方便。
我我的推薦使用這個軟件，由於megacli 工具須要安裝額外的軟件包，有些服務器客戶不容許安裝其餘的軟件包，因此比較麻煩。
這個工具直接安裝了以後就能夠用。
1.1服務器信息：
1.2系統信息：
[root@localhost storcli]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)
1.3 安裝storcli
rpm -ivh storcli-1.03.11-1.noarch.rpm
目錄： /opt/Mega/storcli
注意版本問題
我這臺服務器是DELL R720xd，2012年上線的，因此我用的是storcli.1.03.11版本。
我用的新版本安裝以後，執行命令沒有輸出，因此這一點須要注意。
1.4一些參數定義：
/cx = Controller ID
/vx = Virtual Drive Number.
/ex = Enclosure ID
/sx = Slot ID
1.5爲了管理方便，創建軟鏈接
ln -s /opt/MegaRAID/storcli/storcli64 /bin/storcli
ln -s /opt/MegaRAID/storcli/storcli64 /sbin/storcli
若是不想創建軟鏈接，就在/opt/MegaRAID/storcli 目錄下 執行./storcli64 指令
二、查看當前設備raid控制器相關信息
[root@localhost storcli]# ./storcli64 show all 能夠看到只有一個控制器
