一、普通模式(該機硬盤沒有做磁盤陣列)

1、fdisk -l 查看你的硬盤編號，如sda,sdb 等

2、smartctl --all /dev/sda

smartctl --all /dev/sda #該命令centos自帶

[root@localhost ~]# smartctl --all /dev/sda

二、磁盤陣列 RAID模式

如果該機有做磁盤陣列，那么運行上述命令會報錯，得不到你要的磁盤信息?？梢越柚鶰egaCli命令

MegaCli命令系統(tǒng)不自帶，，需要額外下載，

下載地址：

%20Controllers/RAID%20Controllers%20Common%20Files/8.07.14_MegaCLI.zip

下載之后解壓，

unzip CSA1.5-MegaCli_REL80571.zip

cd MegaCLI/MegaCli_Linux

rpm -ivh MegaCli-8.05.71-1.noarch.rpm

安裝完成

ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/bin/

默認安裝在/opt下面，建立軟鏈到/usr/bin

[root@localhost bin]# /opt/MegaRAID/MegaCli/MegaCli64 -PDlist -aALL
