Does my disk have SMART support? (got outputs)

Question

I can't run SMART tests on disks of our servers and I couldn't make sure if they support this feature or not (CentOS 7.2).

Short story: We have a bunch of identical servers those assambled in a big data cluster. On one of them we are getting (aproximate average of two in a week) disks remounted as read-only.

I wanted to run SMART tests for those disks to find out underlying reason of this repeating problem but I am not able to run SMART tests. When I want just the information, it's fine:

Well, it says "Enabled". If I want to get full information:

or try test:

Short offline self test failed [unsupported scsi opcode]

I also tried running command selecting scsi as device type and in permissive mode but the output is the same. However, I did not try other possible device types: ata, sat[,auto][,N][+TYPE], usbcypress[,X], usbjmicron[,p][,x][,N], usbsunplus, marvell, areca,N/E, 3ware,N, hpt,L/M/N, megaraid,N, cciss,N, auto, test

("test" option says they are scsi) Should I try them? I tried getting some clues from below output:

root@bigd08 ~]# lspci -knn | grep 'RAID bus controller'
03:00.0 RAID bus controller [0104]: Hewlett-Packard Company Smart Array Gen9 Controllers [103c:3239] (rev 01)
07:00.0 RAID bus controller [0104]: Hewlett-Packard Company Smart Array Gen9 Controllers [103c:3239] (rev 01)

Nope, no clues I got. I still want to believe they support SMART. They were purchased in the beginning of this year and isn't it 2017? They must have! Disks are HP brand as well as servers and RAID controllers but manufacturer is Seagate (ST6000NM0024).

I checked the product manual and seen some bits that indicate SMART support. screenshot from Seagate's manual

I don't know which bits it mentions though and how I can check them from command line. I assume they are the bits for which I see from the first smartctl command I run: "Available", "Enabled".

There are a lot of topics over internet which are similar to my case but most of them are about USB disks and left out.

I appreciate any help which I really need to get stable disks. I also accept your comments for why they may get read-only so often.
