onecli收集FFDC日志：
1、将onecli文件拷贝到本地临时目录下(比如/tmp)；
2、 确保onecli文件具有可执行属性，执行命令：chmod +x lnvgy_utl_lxceb_onecli01n-3.2.0_rhel_x86-64.bin；
3、 执行onecli工具（需要用ROOT用户），执行命令：./ lnvgy_utl_lxceb_onecli01n-3.2.0_rhel_x86-64.bin；
4、稍等一段时间，onecli程序会将收集到的信息保存到/var/log/Lenovo_Support 目录下
storcli收集RAIDlog方法如下：
1、解压缩到Linux/ tmp文件夹
2、安装rpm -Uvh /tmp/Linux/storcli-*
3、执行shell命令

故障硬盘判断方式：
1：找到有问题的挂载点：
[root@bdp-bat-worker01 ~]# ls /data/
ls: cannot access /data/disk12: Input/output error
disk1 disk10 disk11 disk12 disk2 disk3 disk4 disk5 disk6 disk7 disk8 disk9
2：找到故障盘：
