Dear Mach!
I want to modify this question asked by my friend somewhat...
While configuring an HACMP cluster 5.1 on two nodes in mutual takeover cascading configuration ... i configure two service ip addresses... one ip is owned by one RG while the other is owned by another RG...however bot ip adresses belong to same logical subnet and vlan...
here is the config
serviceip1 9.168.1.1
serviceip2 9.168.1.2
node1_boot1 9.168.10.1
node1_boot2 9.168.11.1
node2_boot1 9.168.10.2
node2_boot2 9.168.11.2
IPAT with ip aliasing is used... everything is ok ...cluster works ok however when one node failovers two rgs are on same node and the node have ip adresses belonging to same subnet configured onto its two adapters.
e.g if node2 fails....two RGS and hence ip adresses
9.168.1.1 and 9.168.1.2 are on node1
but i am able to ping both ip addresses..
IS IT CORRECT TO HAVE TWO IP ADDRESSES OF SAME LOGICAL SUBNET ON SAME MACHINE...IF NOT THEN HOW THIS CLUSTER MUTUAL TAKEOEVER CONFIG WORKS OK AND VARIFIES
Here comes polani Once again!!!

I would make the following modifications:
serviceip1 9.168.1.1
serviceip2 9.168.1.2
node1_boot1 9.168.10.1
node1_stdby 9.168.11.1
node2_boot1 9.168.10.2
node2_stdby 9.168.11.2
Make sure that you have standby adapters configured for each node. Make the necessary configuration changes within HACMP topogoly.
When you start HACMP on node1, the serviceip1 will takeover what used to be the node1_boot1.
When you start HACMP on node2, the serviceip2 will takeover what used to be the node2_boot1.
When you do a failover from node1 to node2, the serviceip1 will takeover the standby adapter and vice versa.
serviceip1 9.168.1.1
serviceip2 9.168.1.2
node1_boot1 9.168.10.1
node1_stdby 9.168.11.1
node2_boot1 9.168.10.2
node2_stdby 9.168.11.2
