SMART monitoring is not included in the default minimal installation; you will have to install it manually:
yum install smartmontools

Enable the monitoring service; uncomment and edit the various failure/prefailure modes you would like to know about and add your e-mail address to the config file to be notified of errors:
systemctl start smartd ; systemctl enable smartd nano /etc/smartmontools/smartd.conf

Get the basic status of a drive (replace sda accordingly)
smartctl -H /dev/sda

Run self-tests. A short self-test typically completes in under one or two minutes. A full test will depend on the specifications of the drive.
smartctl --test=short /dev/sda smartctl --test=long /dev/sda

You can monitor test progress using the same command you will use to view the results and nitty-gritty:
smartctl -a /dev/sda

Don't be trown off if the values seem out of alignment with the listed thresholds; SMART values are notoriously proprietary. Your main concern is that you receive a status of PASSED
