SMART checks can be performed on hard drives connected to 3ware RAID controllers. The RAID device will be identified as /dev/twa0-15 or /dev/twe0-15 depending on the controller you are using. Each controller will be having ports on to which the hard drives will be connected. For eg: p0 , p1 , p2 etc.

You may use tw_cli command line utility provided by 3ware to identify the ports on which hard drives are connected.

tw_cli /c0/u0 show

Above will give details of RAID configuration for unit 0 (u0) on 3ware RAID controller 0 (c0).

Once you got the information on ports , you may do SMART checks on your hard drives as below,

smartctl -H -d 3ware,0 /dev/twa0
