Hi,
looking at:
http://docs.hp.com/en/B7660-90013/ch06s07.html

Add to /etc/cmcluster/
pkgname.cntl MetroCluster/CA package control script
pkgname_xpca.env MetroCluster/CA environment file
pkgname.ascii ServiceGuard package ASCII configuration file
pkgname.sh Package monitor shell script, if applicable

Hi Peter,
Thanks for giving me a usefull answer and weblink.
I need to configure a package on a 3node cluster but am not using XP for disk storage. Am using EVA5K for shared storage now can you please guide me a bit more.

And i'll definately award points from now on-wards.
waiting for you feedback

EVA implementation with Metrocluster is documented in chapter 4 (pg 227) in
http://docs.hp.com/en/B7660-90019/B7660-90019.pdf - titled,
Designing Disaster Tolerant HA Clusters Using Metrocluster and Continentalclusters, 1st Edition, December 2006

which is located here:

Hi,
Another quick question from you guys. I am planning to add this new package in our already configured metrocluster environment. And in this environement all the packages are getting their storage from XP12k but now am planning to add a package which will get its storage from EVA5K. Is that possible?
and it's basically a 3 node cluster with a local fail over and a remote failover. Is it possible?
Actually i only configured a 2 node cluster so which things should i keep in mind while configuring a 3 node cluster?

Typically, Metrocluster recommends to have equal no. of nodes in both the data centers. So having a 4-node cluster, with 2 nodes in each data-center wld be recommended.
You can certainly have XP and EVA packages in the same cluster; as well as MC and non-MC packages. Just remember that in a MC environment, u shud have quorum service running for lock resolution.

If you are currently using Metrocluster, you must be aware of environment file that must exist to notify Metrocluster of the type of
array the package will use. Though it' not possible to use two different types of arrays in one package, it is possible to use 2 different arrays in a Metrocluster configuration.

In your case, the /etc/cmcluster/pkgdir/pkgname_caeva.env file must exist to guide metrocluster to proper validation of the array before starting the package.
Chapter 4 pg 227 and particularly pg 263 of http://docs.hp.com/en/B7660-90019/B7660-90019.pdf starts the discussion of configuring an EVA-based Metrocluster package.
