As far as i can remember there is no need for NICs used just for
heardbeat. AFAIK hacmp uses every correct configured NIC ( in the sense
of IP ) for heartbeat. So with 3 Nic you have got almost 1 spare. ;-) (
Using IP takeover )

HACMP need NICs to communicate which each cluster member. Since HAMCP
in conjunction with hardware shell provide no single point of failure
you need at least 2 NICs. Its no problem to put any service ip alias to
any nic.
