Linux: Getting SMART status from 3ware cards

Posted by Christian Ashby on March 9, 2010

3ware RAID cards are a very robust hardware RAID solution which work under Linux.

If you use these cards though, the ’3dm2′ web interface and command line interface only give limited information about the health of the drive.

Fortunately the standard tool smartctl can access the drives as if they were directly connected to the system like this:

smartctl -d 3ware,X --all /dev/twa0

Where X is the index (0…n) of the drive you want to check.
