Linux / UNIX: Smartctl Check Hard Disk Behind 3Ware RAID Card

To use the smartctl command to check the health of a hard disk behind a 3Ware RAID card on a Linux or Unix system, you will need to specify the device file for the hard disk and the 3ware,N device type.

Here is the basic syntax for using the smartctl command with a 3Ware RAID card:

smartctl -d 3ware,N /dev/twaN

The N in the 3ware,N device type and the twaN device file represents the controller and disk number. For example, if you want to check the health of the hard disk on controller 2, disk 3, you would use 3ware,2 as the device type and /dev/twa2 as the device file.

For example, to check the health of the hard disk on controller 2, disk 3, you can use the following command:

smartctl -d 3ware,2 /dev/twa2

This will display the SMART data for the hard disk on controller 2, disk 3.

You can use the -H option to check the overall health status of the hard disk.

For example:

smartctl -d 3ware,2 -H /dev/twa2

This will display the overall health status of the hard disk on controller 2, disk 3.

You can use other options and arguments to customize the smartctl command, such as the -a option to display all SMART attributes, or the -A option to display the raw SMART data.
