How to configure Informix to run HDR threads on dedicated link to
secondary server ? As I understand we'll have IP address for this new
Interface Card, but how do we tell informix to send/receive logs over
this link/interface. How does it really work ?

The name of the peer node is a listener thread. HDR will connect to
which ever connection that maps to.

You would create your entry for your secondary and the hostname
portion of the sqlhosts file would be the name of the secondary that
mapped to the new network interface.

Example:
machine 1
name ip addr
m1 1.0.0.1
m2 1.0.0.2

If the new interface was 1.0.0.2, you would want to use 'm2' in your
sqlhosts file configuration for the secondary machines INFORMIXSERVER
entry.

But, that would be the ip address of secondary node. How do I give ip
address of primary node for specific Ethernet port ? What I am looking
for is when primary sends the logs it should send over this dedicated
link. Does configuring sqlhosts on secondary node as suggested above
takes care of it ?

If you want to totally isolate the network traffic, then you would have
to install a separate NIC and setup the network connection to it.
Otherwise, you can simply create a distinct listener thread with it's
own TCP port.
