Where can i configure the script? I should start it at the begin of the
takeover.

The real server has the vip on lo:0 as a hidden device.
In the case of a failover heartbeat starts the director on the backup, that was
the real server. Heartbeat assigns the vip to lo:0 and not to eth0:0.
Normal Operation:
Server 1: heartbeat start
VIP is on eth0:0
lvs start with dr
Server 2: heartbeat start
VIP on lo:0 !--------
hide lo:0 --! because of the
arp problem manually startet
hostroute fpr vip to lo:0 !--------
In case of Failover:
Server 1: heartbeat stop
release vip
Server 2: heartbeat takes control to server2
Assigns vip - vip vip already exist from normal oeration.
I hope that my problem is now transparent. At the begin of the failover-process
a
must stop the manually startet VIP assignment, but how?
