Zone Cluster in VCS

I have 2 systems Node1 and Node2 running VCS5.1 MP1 with solaris10_u8. I want to configure an oracle database in solaris zone which is able to failover to other node. Current Configuration is as following 
The Zone root is on shared storage zonedg. And the zone is able to start on both the systems node1 and node2 when the zonedg ( zoneroot)  is switched over.  Now i do not know how to configure 
the zone under VCS control with hazonesetup



V-16-34-1100 Usage: /opt/VRTSvcs/bin/hazonesetup <SG> <res> <Zone> <passwd> <autostart> <Systems>

What will be the SG, res ? here ? 


node2:/>hagrp -state zoneSG

    For monitoring applications in the zone, VCS requires to run HA commands from the zone as zone root.

    After you ran hazonesetup, there would be a zone username created.  You will need to authenticate these users from the zone.

    Please do the following:

    Login to the local zone:

    globalzone # zlogin localzone

    Set the environment variable:

    localzone # VCS_HOST=<hostname of global zone>
    localzone # export VCS_HOST

    login to the VCS engine from localzone:
    localzone # /opt/VRTSvcs/bin/halogin <username> <password> 

    The username can be found in the main.cf file for the service group and password is the one that you entered while running hazonesetup

    Check and verify if the following files are created in localzone:

    localzone # ls -l ~/.vcspwd
    localzone # ls -l /etc/VRTSvcs/.vcshost

    Probe or online the resources and it should work this time.

    Assuming you want to set the zone up in the existing group (zoneSG) then

    SG: zoneSG
    resource: (whatever you want to call the zone resource, eg: myzoneres)
    zonename: (name of the zone, eg: myzone)
    autostart: (1 if you want it to start when vcs starts, 0 if you want to start it manually on cluster restart)
    Systems: (list of systems that can run the zone, in this case node1, node2)

    Edit: the following whitepaper may also be helpful:

    I brought the resources one by one and then i was able to bring the group ... 

    but i 'm getting following warning  in the engine log

    Now, most of agents provide facility to monitor resources in local zone while agents are installed in Gloabal zone. "containername" attribute is introduced to bring this flexibility.

    If you want to run Oracle and Listener in local zone and monitor them through VCS agents. You can install agents in Global Zone and use containername attribute ( use local zone name ) with resource to make them monitoring in local zone.

    You can refer the document provided by Lee for more details or agent guide for Oracle.

    ftp://ftp.entsupport.symantec.com/pub/support/products/Database_Edition_for_Oracle/302453.pdf

    http://sfdoccentral.symantec.com/sf/5.1/solaris/html/vcs_oracle_agent/apbs06.htm

    However there is bit difference in 5.1, below is update fro Oracle Agent guide.

    The attributes ContainerName and ContainerType are replaced with resource
    type-level attribute ContainerOpts, and a service group-level attribute
    ContainerInfo.
