Hi,

you can check the mcsg documentation or else contact HP for the same.

But I think that technically there shouldnt be an issue.

Make sure that you do not configure the backup lan card - ie do not configure an IP address in your cluster config file. This is our section from the config file

NETWORK_INTERFACE lan3
HEARTBEAT_IP 171.10.20.8
NETWORK_INTERFACE lan0
HEARTBEAT_IP 192.168.0.6
NETWORK_INTERFACE lan4
# This line left blank to define standby Lan card

Hi Marcelo,

you can configure as many heartbeats as you want. You can configure two heartbeats and once data channel and once standby lan as you are planning. But the best would be have the data port carry the heartbeat too. No harm in having three heartbeats. It does not generate much traffic that could affect your data transfer.

Hope this helps.

Sanjay:

Ok, but haven't trhee lan card's in one machine of my cluster configuration(i have a five machine's in my cluster), so your recomendation is valid with this configuration?

You mean , You have five nodes in a cluster.?? Well,

You can configure a third heartbeat too if you want but it depends on how many network card you have on the server. Heartbeat does not generate any netwrok traffic.

Hi,

Heartbeat does not generate much traffic if configured alone. Only when you have configured it with data lan then the heartbeat failure may occur incase of the heavy netwrok load.

Why do you want to specifically configure a new lan card with a diff ip for heartbeat ??/ You can always configure a standby lancard for the primary heartbeat lan card.

What advantage are you going to get ??
