CentOS如何查看硬碟品牌型號等具體資訊，centos品牌型號

首先使用smartctl --all /dev/sda 指令來檢查硬碟資訊，該指令CentOS內建，得到的結果可能如下：

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

這裡的Device Model右側的資訊就是硬碟的具體型號，User Capacity右側的資訊就是硬碟的實際大小，同時也表明該機器並沒有做磁碟陣列。 如果該機有做磁碟陣列，那麼運行上述命令得到的結果可能如下：

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

這裡的Vendor和Product實際上是磁碟陣列卡的資訊，而不是磁碟資訊。

這時可先安裝smart工具，指令為yum install smartmontools,輸入該指令並斷行符號。之後輸入指令： smartctl -a -d sat+megaraid,0 /dev/sda並斷行符號，可得到如下的結果：

這裡的Device Model右側的資訊就是硬碟的具體型號，User Capacity右側的資訊就是硬碟的實際大小。
