So, I have a server which has 7 hardisks, each and everyone of them has smartmontools enabled, except the 7th hardisk (/dev/sdg). Tried force enabling it, did not work. 

root@ac001.bafi:~# smartctl -a /dev/sdg
[unusually long delay]

Even tried to force enable smartctl:

  • How is the device physically connected? Are you sure you don't have a failed disk? – Zoredache Feb 21 '17 at 20:55
  • either the disk is failing, the controller/firmware is at least partly broken, or the manufacturer is so far away from using the standard smart operation that it doesn't support it at all. (or it just does not have smart support, but at least for the drives i have without smart i got way different output) – Dennis Nolte Feb 23 '17 at 08:37
  • ... or smartctl is not using correct translation layer to talk to it. `-r ioctl,2` will produce verbose record of ioctl() transactions with the device -- please run it with these options and post the output somewhere. – sendmoreinfo Feb 24 '17 at 10:41
