CentOS下下查看硬盘型号、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centos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)

- === START OF INFORMATION SECTION ===
- Device Model: SanDisk SD6SB1M128G1022I
- Serial Number: 141218410909
- LU WWN Device Id: 5 001b44 becdaed9d
- Firmware Version: X231600
- User Capacity: 128,035,676,160 bytes [128 GB]
- Sector Size: 512 bytes logical/physical
- Device is: Not in smartctl database [for details use: -P showall]
- ATA Version is: 8
- ATA Standard is: ATA-8-ACS revision 6
- Local Time is: Fri Jan 16 08:35:48 2015 CST
- SMART support is: Available - device has SMART capability.
- SMART support is: Enabled
从上面可以看出,硬盘型号为SanDisk SD6SB1M128G1022I,容量为128GB
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
