Check what exact controller do you have: 

lscpi

or more specified: 

lspci | grep LSI
09:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS3008 PCI-Express Fusion-MPT SAS-3 (rev 02)

example with controller Supermicro LSI AOC-S3008L-L8i https://www.supermicro.com/products/accessories/addon/AOC-S3008L-L8i.cfm

check the mpt3sas module is loaded 

lsmod | grep sas
mpt3sas               222983  1 
raid_class             13554  1 mpt3sas
scsi_transport_sas     41224  1 mpt3sas


Otherwise load it with 

modprobe mpt3sas

ALso you may neeed to download the rpm and install it : https://www.supermicro.com/wftp/driver/SAS/LSI/3008/Driver/

Alternate link : https://www.broadcom.com/products/storage/host-bus-adapters/sas-9311-8i#downloads (another adapter with the same logic) 

Once downloaded you need to install the module according to your kernel. In our case we use kernel  3.10.0-862.11.6.vz7.64.7 Openvz7 SO we will use the next rpm: kmod-mpt3sas-26.00.00.00_el7.3-1.x86_64.rpm

If you face any dep issues do not afraid to install it with --nodeps like 

rpm -i kmod-mpt3sas-26.00.00.00_el7.3-1.x86_64.rpm --nodeps

If everything is fine you should be able to see the loaded modules and smartctl should work fine: 

smartctl --scan
/dev/sda -d scsi # /dev/sda, SCSI device
/dev/sdb -d scsi # /dev/sdb, SCSI device

I know that raid based on sdb: 

smartctl --all /dev/sdb

smartctl 6.6 2017-11-05 r4594 [x86_64-linux-3.10.0-862.11.6.vz7.64.7] (local build)

Error Counter logging not supported

Device does not support Self Test logging

You may see the disks attached with lswh 

lshw -c disk

You need to make sure SCSI generic device driver is loaded (and will be loaded at boot). Simply run: 

lsmod | grep sg

if nothing listed try to activate module: 

modprobe sg

You can add this to autoload: 

echo sg >> /etc/modules

To view SMART details use the next: 

smartctl -a  /dev/sg0  #for Logic Volume
smartctl -a  /dev/sg2 #for disk attached to the 1st channel in my case
smartctl -a  /dev/sg5
