CentOS如何查看硬盘品牌型号等具体信息

时间:2015-07-05 11:24来源:cnblogs.com 作者:绿化树 举报 点击:

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)

Device Model:     WDC WD20EZRX-00DC0B0
Serial Number:    WD-WMC301111333
LU WWN Device Id: 5 0014ee 601111622
Firmware Version: 80.00A80
User Capacity:    2,000,398,934,016 bytes [2.00 TB]
Sector Sizes:     512 bytes logical, 4096 bytes physical
Device is:        Not in smartctl database [for details use: -P showall]
ATA Version is:   8
ATA Standard is:  ACS-2 (revision not indicated)

SMART support is: Available - device has SMART capability.
SMART support is: Enabled

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:      0x6b083fe0e9aa11111cf094800440aee5
Serial number:        00e5ae40048094f01c1111aae9e03f08
Device type:          disk
Local Time is:        Fri Jul  3 15:39:02 2015 CST
Device does not support SMART
 
Error Counter logging not supported
Device does not support Self Test logging

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)
