Add another SUBNET in SG

[Asif Sharif]

Hi All,
Good day!

We are using below ServiceGuard.

T1905CA A.11.20.00.01 Serviceguard

Two Service guard clustered nodes

Node-A# 192.168.2.100
Node-B# 192.168.2.101

Pkg IP: 192.168.2.103 (One package)

Now we need to add three more LAN interfaces e.g. LAN9, LAN10, LAN11 with another subnet (192.168.3.100) in both Nodes.

What configuration changes i need to do in cluster.conf and pkg_conf or do i need to create another package for it?

Asif,

You would edit the cluster ascii file and add more lines just as you did for the first subnet. Note that the lan numbers for each server can differ so you need to know which are connected to each other network-wise. I always make every subnet a heartbeat subnet, by the way, because I am paranoid by nature with other people's systems. For example:

NODE_NAME servera
NETWORK_INTERFACE lan0
HEARTBEAT_IP 192.168.1.50
NETWORK_INTERFACE lan3
HEARTBEAT_IP 192.168.2.50
NETWORK_INTERFACE lan1

NODE_NAME serverb
NETWORK_INTERFACE lan0
HEARTBEAT_IP 192.168.1.51
NETWORK_INTERFACE lan3
HEARTBEAT_IP 192.168.2.51
NETWORK_INTERFACE lan1

Then cmapplyconf (cmcheckconf first) the new configuration and if it is happy, you are done.

Cheers,

T

Hi, You should Shutdown Cluster, after it works.
