How to view the hard drive brand model and other details of CentOS

First, use the smartctl -- all/dev/sda command to check the hard disk information. This command comes with CentOS. The result may be as follows:

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

The information on the right side of the Device Model here is the specific Model of the hard disk, and the information on the right side of the User Capacity is the actual size of the hard disk. It also indicates that the machine has no disk array. If the machine has a disk array, run the preceding command to obtain the following results:

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

Here, the Vendor and Product are actually the information of the disk array card, rather than the disk information.

Install the smart tool with the command yum install smartmontools. Enter the command and press Enter. Enter the command: smartctl-a-d sat + megaraid, 0/dev/sda, and press Enter. the following result is displayed:
