Check with smartmontools

[kkm]

As the title says, how can I check, normally command with:
sudo smartctl -a /dev/sda

It doesn't show complete information,
I need temperature and error message from SMART.

RaidXpert2 GUI is deprecated from 2015 or 2017 and today I can't start on Ubuntu 20.04.

AMD Raid driver works for me, it shows in lsblk.

EDIT:

media@xero:~$ sudo smartctl -a /dev/sda

no complete information from SMART, is that correct?

Short answer: You can't, easily anyway.
Long answer: Manpages for smartctl do have options for getting around the RAID obfuscation of drives for popular professional hardware RAID solutions from LSI/Avago/Broadcom, Areca, HighPoint, etc. but not for software/hybrid RAID.
With the kind of licence that Dot Hill/Seagate put on RAIDCore, you'd be lucky to find someone willing to make the changes to smartctl to add RAIDCore support.
