CentOS如何查看硬碟品牌型號等具體資訊

CentOS如何查看硬碟品牌型號等具體資訊

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-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) Local Time is: Fri Jul 3 16:04:20 2015 CST SMART 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: 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

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：

smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-431.el6.x86_64] (local build) Copyright (C) 2002-12 by Bruce Allen, http: //smartmontools.sourceforge.net === START OF INFORMATION SECTION === Device Model: ST91000640NS Serial Number: 9XG3XXXF LU WWN Device Id: 5 000x50 04fxxxx06 Firmware Version: AA02 User Capacity: 1,000,204,886,016 bytes [1.00 TB] 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 4 Local Time is: Fri Jul 3 16:01:03 2015 CST SMART 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。
