Linux under the Smartmontools tool installation use method

Environment:
System environment: CenetOS6.4 x86_64

One, what is s.m.a.r.t.

Smart is a kind of disk self analysis detection technology, as early as the end of the 90, the basic popularity of each hard disk (including IDE, SCSI) in the running, will have a number of their own parameters, including models, capacity, temperature, density, sector, seek time, transmission, BER, etc. After the hard drive has been running for thousands of hours, many of the intrinsic physical parameters will change, a parameter exceeding the alarm threshold, indicating that the hard drive is close to damage.

Smartmontools is an open source disk control, monitoring tool that can run on Linux,unix,bsd,solaris,mac os,os/2,cygwin and Windows, and it can also run from the boot CD or boot floppy disk to support ata/ Atapi/sata-3 (to-8) bit of hard disk and SCSI hard drive, also supports tape device, its home is in smartmontools.sourceforge.net, actually it is a software package, including two utilities: Smartctl and SMATD. The hard drive it monitors must have S.M.A.R.T features, which are currently available on all hard drives, but are usually not turned on by default, and there are two ways to turn this feature on: 1 through the BIOS setup option 2 via the SMARTCTL command. It can be used to test the health of the hard drive and to alert you before a failure occurs.

Second, enable smart

Smart is the corresponding function with the motherboard BIOS, to use smart, you must first go into the host BIOS settings inside the start of the relevant settings, and then the operating system level of things

Iii. installation of Smartmontools tools and use

1. Direct use of Yum installation

Yum Install Smartmontools-y

2. Detect if the hard drive turns on smart support

Smartctl-i/DEV/SDA

For hard disk device symbols, you can use Fdisk to view

[Root@dazhong ~]# smartctl-i/DEV/SDA
Smartctl 5.42 2011-10-20 r3458 [X86_64-linux-2.6.18-371.3.1.el5] (local build)
