Wow someone who has heard of this.
Yes, we have our interconnects set to etherfp.
LLT link information:
Link Tag State Type Pri SAP MTU Addrlen
Xmit Recv Err LateHB
Broadcast
0 eri0 on etherfp hipri 0xCAFE 1500 6
261840450 240300348 0 89
FF:FF:FF:FF:FF:FF
1 ce1 on etherfp hipri 0xCAFE 1500 6
261914713 240332338 0 91
FF:FF:FF:FF:FF:FF
we have 2 interconnects but they are of differnts speeds:
set-node VLDBN1
set-cluster 10
link eri0 /dev/eri:0 - ether - -
link ce1 /dev/ce:1 - ether - -
I believe ce1 is the 2 gigabit
and eri0 is the 100M
This setting was done by our SA. We do have a ce0 which is another 2 gigabit,
but our SA wants to leave this for public connection. Do have a similar setup?
So if I understand we should try setting set-nofastpath 1 in our /etc/llttab so
it will use the slower connection to perform a heartbeat check?
Thanks so much for responding.

Hi Lizz,
I posted this response on oracle-l, but it doesn't seem to have appeared.
On a customer of ours 3 node cluster VCS v3.5 (HP-UX), we had to set
"set-nofastpath 1" in /etc/llttab so as to force the heartbeat to operate at
100Mhz. Have you got 2 heart beat interconnects? i.e. redundancy?
You can get stats by running lltstat, which shows data volumes and errors.
You can run lltstat -l to check the setting of fastpath. "ether" means fastpath
is disabled, "etherfp" means enabled.
