smartctl with 3ware RAID controller

The below information is extracted from the smartctl man page.

To look at ATA disks behind 3ware SCSI RAID controllers:

smartctl -a -d 3ware,N /dev/sda
smartctl -a -d 3ware,N /dev/twe0
smartctl -a -d 3ware,N /dev/twa0

Where N is the disk number.

Devices /dev/sda and /dev/twe0 is used with 3ware series 6000, 7000, and 8000 controllers that use the 3x-xxxx driver.

/dev/sda form is deprecated starting with the Linux 2.6 kernel.

/dev/twa0 is used with 3ware 9000 series controllers, which use the 3w-9xxx driver.

You can also check on the series with the below command:

lspci |grep 3ware
