assigning ip address for package.

[khilari]

Hi people, i wanted to know how do u assign floating ip address to a package.
And another thing. Now, there are services within a package so does each service has its own ip address which when failed on one node goes onto the other.....
So, its basically the service ip address which is called the package ip address.
Kindly clear on this.
Thanks.

An IP address is assigned for a package in the package control script, along woth the subnet it has to go on to.
Look for the following:
#IP[0]=""
#SUBNET[0]=""

I would recommend you try reading the managing Serviceguard manual at:
http://docs.hp.com/en/ha

Or even attending a class on Serviceguard

Khilari,

Ip address is assigned to a package and not service. Alternatively you can configure each service as a package and assign an ip address to each , this may be useful for load sharing but of no use if all the services now configured as packages were to run on the same node.

Well, what i really meant to ask was that how do u give it an ip address. I mean first of all i read the command cmmodnet configures the ip address. But, who determines what the ip address of that particular package will be, and what is the criteria to determine that.
Thanks

Khilari,

The cmmodnet is to be used in your package control script - you will have a package control script for every package configured on your cluster - e.g. /etc/cmcluster/packagename.cntl

As part of your package control script you will have to activate VGs, mount filesystems , assign ip addresses to your lan card ports, start services - service startup will be with cmrunserv etc. etc.
Please refer to Managing service guard manual at http://docs.hp.com/en/ha#Serviceguard
