RAID卡

简介

RAID模式介绍

Linux下raid卡工具

安装

使用

进入/opt/MegaRAID/storcli，只有在这个目录下，才能执行（因为没有加入系统path）。
Raid数量及当前状态

[root@seg1 storcli]# pwd
/opt/MegaRAID/storcli
[root@seg1 storcli]# ./storcli64 show ctrlcount
Status Code = 0
Status = Success
Description = None

Controller Count = 1

查看基础信息

[root@seg1 storcli]# ./storcli64 /c0 show

查询虚拟磁盘大小，raid结构等.
因为有2个raid配置，分别执行v0和v1来看，发现第一个做的是RAID1，第二个做的是RAID5
