Configuring Heartbeat with Serviceguard A.11.17

[Feljav]

Can i configure a cluster with serviceguard A.11.17 having two cluster heartbeat lan interfaces(in each node) conected with crossover cables? Both heartbeat lan interfaces are in the same subnet, and they are not being utilized by any clients for data traffic.

Hi,

You can configure SG cluster with such a configuration, but it's not a good idea to have two NICs on the same subnet. Configure them in different subnets and run
#>cmquerycl -C /etc/cmcluster/cluster.ascii -n node1 -n node2
and edit the ascii file according to your needs.

Shalom,

HP-UX networking does not like two lan cards on the same subnet.

In earlier releases of HP-UX 11i v1 this would lead to sudden loss of networking.

That is why you should use set_parms or edit /etc/rc.config.d/netconf and then execute the command Victor recommends.

Since you propose crossover cables (which are supported with Serviceguard), it is apparent that these heartbeat networks are also private networks. Therefore, you have no real need to keep them both on the same subnet. I concur with previous writers - change the subnet of one of the HB networks to avoid trouble.
