Check SMART with software or hardware raid (MegaRaid)

#!/bin/bash

## Prerequisites :
# smartmontools - Sudo command & espacially (sudo /usr/sbin/smartctl).
# MegaCli (MegaRAID) if needed.
# HP ACU Cli (HP RAID) if needed.

# backup ALL= NOPASSWD: sudo /sbin/MegaCli -pdlist -a0
# backup ALL= NOPASSWD: sudo /usr/sbin/smartctl
# backup ALL= NOPASSWD: /sbin/fdisk -l

## To have the Device ID for all MegaRAID disks:
# sudo /sbin/MegaCli -pdlist -a0 | grep 'Device Id' | sed 's/Device Id: //' | sort
