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
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.
如下是安装过程:
