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.
