Introduction to hard disk management tools: smartctl

[root@localhost scripts]# smartctl --all /dev/sda -bash: smartctl: Command not found [root@localhost scripts]# yum search smartctl -y //Loaded plug-in: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com ======================================================================================= Match: smartctl ======================================================================================== smartmontools.x86_64 : Tools for monitoring SMART capable hard disks [root@localhost scripts]# yum install smartmontools.x86_64 -y

smartctl -i define equipment -d Specify device type,For example: ata, scsi, marvell, sat, 3ware,N -a or A Show all information -l Specifies the type of log, for example:TYPE: error, selftest, selective, directory,background, scttemp[sts,hist] -H View the health status of the hard disk -t short Background detection of hard disk, short time consumption -t long Hard disk detection in the background takes a long time -C -t short The front desk detects the hard disk, which takes a short time -C -t long The front desk detects the hard disk, which takes a long time -X Interrupt background detection of hard disk -l selftest Display hard disk test log
