Good Morning!

Glad you have your system running again!

As you might know in the meantime, these are hints for working with a 
non-starting system:

zpool import shows all your pools on a boot with an USB image

zpool import rpool

beadm list

beadm mount ......

bootadm install-bootloader -M -f -P rpool


It is always a good idea to be prepared for such 'events' and have a 
booklet with hints and maybe tried out some bad scenarios with a vm...

i am not prepared :-/

Greetings,

Stephan
