Thank you for detailed explanation.
(sorry to late reply, I am not so good at english)

I know I have to restore the system as soon possible when the system be
It depends on the case, unfortunately I need the much time for 
restore the system.
The better way is DHCP configuration would be chane to with out

So I have to get ready "failover configuration file" and "no failover
configuration file" for trouble?
Then they will exchange the files when the peer partner be down?
Becase, DHCP server can not change sate FREE while peer partner be down
when I still use failover.
(This case is needs the time so much for repaire)
