下载并安装lsi MegaRAID raid卡 管理工具

单盘可以做raid0，只是没有任何增益效果，唯一就是能让raid卡识别硬盘。那些说raid0至少要2块硬盘的，都是理论课党，常玩阵列卡的都知道raid0无限制

背景:

lsi MegaRAID raid卡管理工具能查如下信息:
raid的level,

raid是几块物理硬盘构成的,

物理硬盘的制造商.

首先,介绍下Linux系统中查看raid厂商.

软件raid：查看raid级别，状态等信息
#cat /proc/mdstat

硬件raid：查看raid的厂商，型号，级别
#dmesg | grep -i raid
#cat /proc/scsi/scsi

比如如下的输出:

[root@rac1 disk]# dmesg | grep -i raid
[    2.657117] megaraid_sas 0000:01:00.0: irq 95 for MSI/MSI-X

这就确定是LSI的raid卡控制器.

下载并安装lsi MegaRAID raid卡 管理工具

下载网址:
http://www.avagotech.com/support/download-search
在如上的网址中,在搜索框里搜索"megacli",点击确定,找到Management Software and Tools (188) 下的 MegaCLI 5.5 P2  (这是命令行工具),
注意不要下载Latest MegaRAID Storage Manager (MSM) ,这个MSM是图形化的管理工具.

另:lsi已经被avago收购了.
