Hi All,

I am very new to HACMP, and trying to configure a simple 2 node
cluster. After reading the redbooks, I am in the process of
configuring my network. Currently, I have 3 NICs on each node.

My question is, do all 3 (6 total) IP addresses need to be on the same
subnet, for HACMP to function properly?

TIA!

They can be on the same physical network.
But they have to be logically separate networks.
(Logically seperate them using netmask!)
Depending on the topology you use you need to pick the addresses.

You need each one of adapter (2 actually one on each node)
to be on different logical subnets.

Congratulations, you confused me :-)


I am currently putting everhing on the samesubnet, this seems to work
fine. However, will it work on different subnets? Can I use a TCP/IP
for hearbeat interface?
