How CentOS can view specific information such as the hard drive brand model

First use the SMARTCTL--ALL/DEV/SDA directive to check the hard disk information, the command CentOS comes with, the results may be as follows:

< Span style= "line-height:1.5" The information on the right side of the device model here is the specific model of the hard disk, the information on the right side of the User capacity is the actual size of the hard disk, and it also indicates that the machine does not have a disk array. If the machine has a disk array, the result of running the above command may be as follows:

< Span style= "line-height:1.5" >vendor:               DELL

The vendor and product here are actually information about the disk array card, not the disk information.

At this point, you can install the Smart tool, instructions for yum install smartmontools, enter the command and return. After entering the command: smartctl-a-D SAT+MEGARAID,0/DEV/SDA and enter, you can get the following results:

sm Artctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-431.el6.x86_64] (local build)
