local switch parameters?

[Doug O'Leary]

Hey;

It's been awhile since I had to configure local switching on a cluster - and even longer since I went through the mcsg class. I seem to remember that being a parameter in the cluster configuration file - not the package configuration file. Am I missing something?

Here's the set up:

lan0 192.168.240.xx
lan1 <
lan2 10.1.11.xx
lan3 10.1.10.xx

I'd like lan0 to be able to fail over to lan1 in case lan0 fails. I'm all but certain that's possible as I seem to remember doing it - however, as mentioned, I thought it was a cluster config, not a package.

Can someone help an ailing memory with what I need?

Appreciate the time.

Hi,

see below lan1 is a standby to lan0

NODE_NAME node1
NETWORK_INTERFACE lan0
STATIONARY_IP 192.168.240.xx
NETWORK_INTERFACE lan1 ---------> standby for lan0
NETWORK_INTERFACE lan3
HEARTBEAT_IP 10.1.11.xx

lan0 192.168.240.xx
lan1 <
lan2 10.1.11.xx
lan3 10.1.10.xx

Right, does lan1 show as setup in the cluster configurastion? Use cmviewconf and check that lan1 and lan0 are in the same bridged net.

If that is fine, then there are two places to specifiy this subnet in Legacy packages, the package configuration file and the package control script.
In the conf file, there is the SUBNET parameter, and the Network Manager will use this parameter (if set) to monitor this subnet when the package is runnning, and also allow the failover to occur.
You also have to have the LOCAL_LAN_FAILOVER_ALLOWED set to YES.

In the script, there is the IP and SUBNET parameter pair, that is used to add the relevant IP address to the relevant subnet.
So, add the subnet into the package configuration, and the NW manager should then handle the local failover

ah; Sweet! So, mcsg picks that up automatically now. I could be misremembering, but I seem to remember that I had to specify a standby nic. That was about 2001, though, so there's been a few upgrades since then.

Thanks, all for the replies. That's what I was looking for.
