   I was check this time starting when I have been send the shutdown to server until the second VIP interface up on second node (backup node).

 Can you also send crsd.log?

Ok, following the address because the size ... http://rafb.net/p/hqE13995.html

When I send the power off on first node, on second node (crsd log on link above), on line 1 log the message "[ COMMCRS][1147169120]clsc_receive: (0xc6d180) Error receiving, ns (12535, 12560), transport (505, 110, 0)" and still "Connection not active" until line 2045.

PS: Now, my VIP address of first node don't migrated to second node later power off ... (maybe will be necessary re-install the OS and Oracle ClusterWare, because I've changed the system a lot of to test)

 Further, refer $CRS_HOME/bin/racgvip and there are few parameters such as
> check interval, restart attempts etc controlling behavior of VIP failover

Yes, I checked this file too, but don't changed.

Now, looking the crsd log file, I believe the Oracle know when another node is out, but who is responsible to make a failover (mount the aliases of VIP on another machine) !? (Script, Daemon, Angel :P )

Thank you friends for help.
