[操作系统]CentOS如何查看硬盘品牌型号等具体信息


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)Copyright (C) 2002-12 by Bruce Allen, http://smartmontools.sourceforge.net=== START OF INFORMATION SECTION ===Device Model:   WDC WD20EZRX-00DC0B0Serial Number:  WD-WMC301111333LU WWN Device Id: 5 0014ee 601111622Firmware Version: 80.00A80User Capacity:  2,000,398,934,016 bytes [2.00 TB]Sector Sizes:   512 bytes logical, 4096 bytes physicalDevice is:    Not in smartctl database [for details use: -P showall]ATA Version is:  8ATA Standard is: ACS-2 (revision not indicated)Local Time is:  Fri Jul 3 16:04:20 2015 CSTSMART 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:        DELLProduct:       PERC H310Revision:       2.12User Capacity:    999,653,638,144 bytes [999 GB]Logical block size:  512 bytesLogical Unit id:   0x6b083fe0e9aa11111cf094800440aee5Serial number:    00e5ae40048094f01c1111aae9e03f08Device type:     diskLocal Time is:    Fri Jul 3 15:39:02 2015 CSTDevice does not support SMARTError Counter logging not supportedDevice 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:

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。
