StorCLI即Storage Command Line Tool 是LSI公司开发的RAID卡命令行管理工具。主要用于服务器内部RAID管理。
安装storcli前，服务器本地硬盘故障更换过程中，在message中只有如下2行日志，无法得到详细信息

查看raid卡类型
# lspci |grep RAID

可到服务器的官网下载相应的包，本例下载ul_avago_storcli_1.18.11_anyos.zip，下载后ftp到/opt目录下
# unzip ul_avago_storcli_1.18.11_anyos.zip
# cd storcli_all_os/Linux
# rpm -ivh storcli-1.18.11-1.noarch.rpm

rpm安装后 storcli64所在路径为/opt/MegaRAID/storcli/storcli64，可以直接运行storcli64工具，
为了使用方便，可以考虑将/opt/MegaRAID/storcli追加到系统PATH变量，或做链接
ln -s /opt/MegaRAID/storcli/storcli64 /bin/storcli
ln -s /opt/MegaRAID/storcli/storcli64 /sbin/storcli
