Smartmontools - zypper/yum/apt-get in/install smartmontools
First query the MegaRAID controller to get the list of DID's for the drives needing to be queried . In this case 43,81,82,83 These DID's will be used when running the smartctl command later.
Next run lsblk -l to get your drive letter. We will be using /dev/sdb
With the information gathered on the first two commands you can now run smartctl to query the drives. You will need to change the DID for each drive and in this case since the drives are in a RAID /dev/sdb does not change when running the command.
