help configuring heartbeat

[tam1]

Hi everyone

I'm looking for some advice regarding configuring heartbeats. Hopefully I’m going along the correct path.

Our 2 cluster members each have 5 network cards each.
i would like to have -
1 primary
1 standby
and 2 as dedicated heartbeats.

Details of the cards are :

# ioscan -fnC lan
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
lan 0 0/1/2/0 iether CLAIMED INTERFACE HP AB352-60003 PCI/PCI-X 1000Base-T Dual-port Core
lan 1 0/1/2/1 iether CLAIMED INTERFACE HP AB352-60003 PCI/PCI-X 1000Base-T Dual-port Core
lan 2 0/2/1/0 igelan CLAIMED INTERFACE HP A6825-60101 PCI 1000Base-T Adapter
lan 3 0/5/2/0 igelan CLAIMED INTERFACE HP A6825-60101 PCI 1000Base-T Adapter
lan 4 0/6/1/0 igelan CLAIMED INTERFACE HP A6825-60101 PCI 1000Base-T Adapter

I have so far configured the primary card Lan0, the standby card Lan3is unconfigured.
I have given the 2 heartbeat cards an IP address each.

# netstat -in
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
lan2 1500 192.168.104.0 192.168.104.5 181 0 192 0 0
lan0 1500 172.25.80.0 172.25.81.98 3324897 0 4596985 0 0
lo0 4136 127.0.0.0 127.0.0.1 752220 0 752220 0 0
lan4 1500 192.168.104.0 192.168.104.6 12612 0 192 0 0

/etc/rc.config.d/netconf
INTERFACE_NAME[0]=lan0
IP_ADDRESS[0]=172.25.81.98
SUBNET_MASK[0]=255.255.252.0
ROUTE_GATEWAY[0]=172.25.80.1

IP_ADDRESS[2]=192.168.104.5
SUBNET_MASK[2]=255.255.255.0
INTERFACE_NAME[2]=lan2

IP_ADDRESS[4]=192.168.104.6
SUBNET_MASK[4]=255.255.255.0
INTERFACE_NAME[4]=lan4

Do I need to put the heartbeat information in /etc/hosts.
Also should my cluster file look like this :

NETWORK_INTERFACE lan0
HEARTBEAT_IP 192.168.104.5
HEARTBEAT_IP 192.168.104.6
NETWORK_INTERFACE lan3

Your advice is greatly appreciated

Cluster file doesn't look right, does it not contain lan2 and lan4?

netconf looks correct

[Richard.Brown · Accepted solution]

Sorry that was a little vague, cluster file should look like

NETWORK_INTERFACE lan2
HEARTBEAT_IP 192.168.104.5

NETWORK_INTERFACE lan4
HEARTBEAT_IP 192.168.104.6

Enter into /etc/hosts as required

Hi Richard

does this mean that lan2 and lan4 would be used for data as well as heartbeat?

I would prefer to keep them as dedicated heartbeats only.

Thanks

[Richard.Brown]

I agree with you on dedicated heartbeats, which they should be as they are on different subnets.

Are you connecting the heartbeats via a hub or xover ?

Hi Richard

the heartbeats are connected into cisco switches

Thanks
