linux命令--查看硬盘信息（磁盘阵列模式下）

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 -lWARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT.

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：

http://www.avagotech.com/support/download-search

我下载到/root/usr/local目录下

[root@localhost local]# ls8-07-10_MegaCLI_Linux.zip  etc    include  lib64    sbin   srcbin                        games  lib      libexec  share

然后解压

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

安装MegaCLI，默认安装在/opt下面，建立软链到/usr/bin

[root@localhost Linux MegaCLI 8.07.10]# rpm -ivh MegaCli-8.07.10-1.noarch.rpm Preparing...                ########################################### [100%]   1:MegaCli                ########################################### [100%][root@localhost Linux MegaCLI 8.07.10]# ln -s /opt/MegaRAID/MegaCli/install.log                 libstorelibir-2.so.14.07-0  libstorelibir-2.so          MegaCli64                   [root@localhost Linux MegaCLI 8.07.10]# ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/bin/

安装完成，命令查看硬盘信息
