首先使用smartctl --all /dev/sda 指令来检查硬盘信息，该指令CentOS自带，得到的结果可能如下：

			
									smartctl 5.43 2012-06-30 r3573 
[x86_64-linux-2.6.32-358.el6.x86_64] (local build)

这里的Device Model右侧的信息就是硬盘的具体型号，User Capacity右侧的信息就是硬盘的实际大小，同时也表明该机器并没有做磁盘阵列。如果该机有做磁盘阵列，那么运行上述命令得到的结果可能如下：

			
									Vendor:               DELL
								
									Product:              PERC H310
								
									Revision:             2.12
								
									User 
Capacity:        999,653,638,144 bytes [999 GB]
								
									Logical block size:   512 bytes
								
									Logical Unit id:

									Serial

这里的Vendor和Product实际上是磁盘阵列卡的信息，而不是磁盘信息。

这时可先安装smart工具，指令为yum install smartmontools,输入该指令并回车。之后输入指令： smartctl -a -d sat+megaraid,0 /dev/sda并回车，可得到如下的结果：

			
									smartctl 5.43 2012-06-30 r3573 
[x86_64-linux-2.6.32-431.el6.x86_64] (local build)
