Adding existing VG to powerHA Resource group
Hello. I am Running AIX 6.1 and PowerHA 6.1
I have an active/active cluster (Prod/Dev) cluster. Each side will failover to the other.
I have on my prod side an active volume group with a file system. The VG is imported on both nodes and active (varried on, file system mounted) on the prod node.
I would like to add this VG, which has been active for a time, to the resource group of the Prod node.
From my knowledge (such as it is) and research, I have the following as my plan:
Do a discovery
Add the vg to the resource group
Do a sync/verify
Anything I am missing? Can I do these safely while the cluster is active? Any small configfuration items that may pop up?
Thanks for your time and any suggestions.

NAME
groups - Displays your group membership
SYNOPSIS
groups [user]
DESCRIPTION
The groups command writes to standard output the groups to which you or the specified user belong. The Tru64 UNIX operating system allows
a user to belong to many different groups at the same time.
Your primary group is specified in the /etc/passwd file. Once you are logged in, you can change your active group with the newgrp shell
command (see sh). When you create a file, its group ID is that of your active group.
Other groups that you belong to are specified in the /etc/group file. If you belong to more than one group, you can access files belonging
to any of those groups without changing your primary group ID. These are called your concurrent groups.
NOTES
The /etc/passwd and /etc/group files must be on the same node.
EXAMPLES
To determine your group membership, enter: groups
The groups to which you belong will be displayed. For example: devel prod
FILES
Contains group information. Contains user information.
