linux下查看硬盘型号、大小等信息（含Raid）
linux下查看硬盘型号、大小等信息（含Raid）
一、普通模式（该机硬盘没有做磁盘阵列）
1、fdisk -l 查看你的硬盘编号，如sda,sdb 等
2、smartctl --all /dev/sda
smartctl --all /dev/sda #该命令redhat自带
[root@localhost ~]# smartctl --all /dev/sda
smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-504.el6.x86_64] (local build)

二、磁盘阵列 RAID模式
如果该机有做磁盘阵列，那么运行上述命令会报错，得不到你要的磁盘信息。可以借助MegaCli命令
MegaCli命令系统不自带，需要额外下载，
下载地址：
http://www.lsi.com/downloads/Public/RAID%20Controllers/RAID%20Controllers%20Common%20Files/8.07.14_MegaCLI.zip
下载之后解压，
unzip CSA1.5-MegaCli_REL80571.zip
cd MegaCLI/MegaCli_Linux
rpm -ivh MegaCli-8.05.71-1.noarch.rpm
安装完成
ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/bin/
默认安装在/opt下面，建立软链到/usr/bin
[root@localhost bin]# /opt/MegaRAID/MegaCli/MegaCli64 -PDlist -aALL
