I‘ve CentOS Linux and FreeBSD based server running using 3Ware (9650SE-2LP) RAID card. I know how to check hard disk behind Adaptec raid controllers, but how do I look at ATA / SATA disks behind 3ware SCSI RAID controllers using smartctl command?
You need to use the following device names:
a) IDE / ATA – /dev/hd[a-t]
b) SCSI / SATA – /dev/sd[a-z] OR /dev/twe[0-9] OR /dev/twa[0-9]
HowTo: Look at ATA / SATA Disks Behind 3ware SCSI RAID Controllers
Use the following syntax:
smartctl -a -d 3ware,N /dev/tweY smartctl -a -d 3ware,N /dev/twaY |
The argument 3ware,N, the integer N is the disk number (3ware “port”) within the 3ware ATA RAID controller. The allowed values of N are from 0 to 31 inclusive. You can use the following tw_clin command to find out 3ware port and check RAID card health:
# tw_cli info
Sample outputs:
Ctl Model (V)Ports Drives Units NotOpt RRate VRate BBU
------------------------------------------------------------------------
c0 9650SE-2LP 2 2 1 0 1 1 -
To get port info for c0 controller, enter:
# tw_cli info c0
Sample outputs:
Unit UnitType Status %RCmpl %V/I/M Stripe Size(GB) Cache AVrfy ------------------------------------------------------------------------------ u0 RAID-1 OK - - - 232.82 W ON VPort Status Unit Size Type Phy Encl-Slot Model ------------------------------------------------------------------------------ p0 OK u0 233.81 GB SATA 0 - WDC WD2503ABYX-01WE p1 OK u0 233.81 GB SATA 1 - WDC WD2503ABYX-01WE
Type the following command to view smart information about the hard disk behind 3Ware RAID card, enter:
# smartctl -a -d 3ware,0 /dev/twa0
# smartctl -a -d 3ware,1 /dev/twa0
Sample outputs:

Please note that if the special character device nodes /dev/twa? and /dev/twe? do not exist, or exist with the incorrect major or minor numbers, smartctl will recreate them on the fly. Typically /dev/twa0 refers to the first 9000-series controller, /dev/twa1 refers to the second 9000 series controller, and so on. Likewise /dev/twe0 refers to the first 6/7/8000-series controller, /dev/twa1 refers to the second 6/7/8000 series controller, and so on.

Many thanks, just what I needed!
typo here
Likewise /dev/twe0 refers to the first 6/7/8000-series controller, /dev/twa1 refers to the second 6/7/8000 series controller, and so on.
good info.
Thank you for sharing this!
Within one of my systems a 9750-8i is used. To get smart info about a disk I have to use /dev/twl0 as device …
for example
smartctl -a -d 3ware,17 /dev/twl0
i have the 9750-4i and all disks connected as SINGLE and i had to use this line for disk 9
smartctl -a -d 3ware,9 /dev/tws0
Hi,
Need some help here with my 3ware 9750-8i raid controller card. I can see the controller and hdd at booting stage but I can not see the hdd in Centos. I even have latest firmware update but still no hdd detected.
Thanks
