So, I put 'log_level = 5' into /etc/tcmu/tcmu.conf , restart
tcmu0runner and see only this in its logs :

Wikipedia says that 1A is 'mode sense' and 9e is 'service action in'.
These records are logged when I try to put the disk online or
initialize it with GPT/MBR partition table in Windows Disk Management (and
Windows report errors after that)
What to check next ? Any importance of missing 'SSD' device class ?
