SMART Data through HP Raid Controller
To be able to view the SMART data of disks behind a raid controller, the driver for the controller would have to be used to communicate with the drives.
The command to be able to do this would be via the following command,
smartctl -d sat+cciss,X -a /dev/sdY
X would have to be substituted for the bay number starting from 0, with Y being the block device.
An example for this would be:
smartctl -d sat+cciss,0 -a /dev/sda
