Firstly do a cmviewcl -v, you will get the node status

Then check the /etc/cmlcuster/cluster config file and check the ip address of the cluster

otherwise you might also get it in the /etc/hosts file

Shalom,

I would use some version of the cmviewcl command.

You might also try traceroute and try and get the MAC address of the ip address assigned to float.

The question is whether you need to determine this from the outside or can log in to both nodes and use cmviewcl or other Service Guard Tools.

Knowing what IP address to connect to, is something you have to get from the package configuration file. It has to be hard coded there.

apply command "cmviewcl", the out will show you the node name. and then ping that node name will show you the IP address.

Hi,

To start with there is nothing called cluster IP. I believe you are refering to package IP.

cmviewcl -v -p

The above will give you primary node and secondary node of the package.

Take the subnet from the above o/p

netstat -ni|grep -i

The interface which has lanX:1 is the package IP.

X is the PPA of LAN interface.

Second way

Check the package config file to see the primary and secondary node. Check the package control file for package IP.

Package config and control file are in /etc/cmcluster//

Cheers,
Ravi.
