Yes, now it is working! Comm daemons starts on primary and secondary without error.
Comm daemon registered his leafs only on internal network that is correct.
When I terminate primary, secondary take control(starts dataservice and scheduler, comm and server starts prior).
I ask in this post how to set PBS_LEAF_NAME and conclusion was that I need use short hostname - not with domain. So conclusions from that post are wrong:
SOLUTION and conclusion is:
PBS_LEAF_NAME should be FQDN of hostname which resolves to IP of internal network!
Many thanks for Your help!
