In OpenAIS for example, in /etc/ais/openais.conf you have a directive called
interface. In this directive you specify a ringnumber, bindnetaddr, mcastaddr
and mcastport. Configuring 2 communication channels means using adding
rrp_mode: passive, ringnumber 0 and ringnumber 1, two interface directives in
which you use different bindnetaddr IP addresses (ex: 10.0.0.1 and 10.0.0.2,
or whatever IP's you use, but preferably each IP address should be assigned
to a different network interface), two different mcastaddr multicast groups
(or mcastport, but I'd recommed different mcastaddr's in the range of
239.x.x.x).
The principle behind it is if one communication channel (network card, IP
address connectivity, multicast group/port) fails, the other one is still
there for redundancy. I see this similar to the way ring network topologies
work, without the token.

p.s.: Andrew, nice to have you back, to paraphrase a famous quote "Mr.
Anderson. Welcome back, we missed you."
Thanks that helps a lot
Just one more thing
If two interfaces are configured are they both used equally

The DRBD manual says
It is absolutely vital to configure at least two independent OpenAIS
communication channels for this functionality to work correctly.
My Google'n has not yielded any results in the how to do this department
I have DRBD configured and working properly with one channel
Where can I find info to add a second channel
