Check Disk Health Status When Using Hardware RAID

I have several boxes using RAID controller from LSI brands. And of course, sometimes we need to know important information about our disks, let say disk health status.

When using Software RAID then the command is very simple, eg:

smartctl -a /dev/sda

However, when using a hardware RAID, the command is slightly different:

# Physical drive information
MegaCli -PDList -aALL

# Outputting device ID
MegaCli -PDList -aALL | grep "Device Id"

# Smartctl test
smartctl -a -d sat+megaraid,#DeviceID /dev/sd[a-z]

Note: the RAID controller is MegaRAID LSI.
