yep, the selftest works:

SMART Self-test log
Num  Test              Status                 segment  LifeTime  LBA_first_err [SK ASC ASQ]
     Description                              number   (hours)
# 1  Background long   Self test in progress ...   -     NOW                 - [-   -    -]
# 2  Background short  Completed                   -    6921                 - [-   -    -]


... and after completed:
