megacli的安装通过如下链接http://down.51cto.com/data/2042596或者http://pan.baidu.com/s/1eQ2FeHc
下载至windows本地桌面,然后在linux命令行用命令:rz -be ,在弹出的窗口中选择刚才下载的压缩包(注意不要勾选已ASCII码方式传送文件)tar xf megacli-8.02.21-1-mdv2012.0.x86_64.rpm.tar
rpm -ivh megacli-8.02.21-1-mdv2012.0.x86_64.rpm默认yum源木有,为了安装方便,可以手工添加到本地yum源,以后安装就可以执行如下命令:
yum install megacli -y (关于本地yum源的搭建,请移步本地yum源搭建)一、查看Raid卡信息
megacli -LDInfo -Lall -aALL [root@ robin]# megacli -LDInfo -Lall -aALL
