linux 查看磁盘信息命令行,linux命令

如果服务器有做磁盘阵列，那么运行fdisk -l或者smartctl –all /dev/sda，得不到你要的磁盘信息。

[root@localhost /]# fdisk -l

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，搜索MegaCLI即可找到：

我下载到/root/usr/local目录下

[root@localhost local]# ls

8-07-10_MegaCLI_Linux.zip etc include lib64 sbin src

bin games lib libexec share

然后解压

[root@localhost local]# unzip 8-07-10_MegaCLI_Linux.zip

Archive: 8-07-10_MegaCLI_Linux.zip

inflating: 8.07.10_MegaCLI_Linux/Linux MegaCLI 8.07.10.txt

creating: 8.07.10_MegaCLI_Linux/Linux MegaCLI 8.07.10/

inflating: 8.07.10_MegaCLI_Linux/Linux MegaCLI 8.07.10/MegaCli-8.07.10-1.noarch.rpm

找到安装包

[root@localhost local]# ls

8.07.10_MegaCLI_Linux bin games lib libexec share

8-07-10_MegaCLI_Linux.zip etc include lib64 sbin src
