Thank you guys, you are right. The BIOS provides only 1 disk to the 
loader! I checked it from loader prompt by lsdev (booted from USB 
external HDD).

So I will try to make a small zpool mirror for root and boot (if ZFS 
mirror can be made of 4 providers instead of two) and the rest will be 
in RAIDZ.

If that fails, I will go my old way with internal USB flash disk with 
UFS for booting and RAIDZ of 4 disks for storage as I did it few years 
ago with 7.0 or 7.1.

Thank you again!
