Installing shared agent on NFS

I'm trying to deploy EM 12.1.0.2 agents on a 2-node RAC cluster with shared directories on NFS. After I installed the first agent I use the instructions in the documentation http://docs.oracle.com/cd/E24628_01/install.121/e24089/install_agent_usng_shrd_hm.htm to install the shared agent.
Deployment Type ->Add Host to Shared Agent
Target -> node1
OH -> Same as target on node1 (/u02/oracle/agent12c)
Instance -> /u02/oracle/agent12c/node2/agent_inst
However, it fails at the Prerequisite steps because it detects an existing agent on the host. Here's a snippet of the logs which gives the failed pre-reqs:

2013-05-13_11-43-34:INFO:DESCRIPTION:This is a prerequisite condition to ensure that there is no agent home exist on the host. RESULT: WARNING RESULT TEXT: Expected result: EM Agent should not exist in host.
Actual Result: An agent home already exists
Check complete. The overall result of this check is: Failed <<<<
2013-05-13_11-43-34:INFO:DESCRIPTION:This is a prerequisite to check if Agent Oracle Home or Install Base Directory, is already registered with inventory RESULT: FAILED RESULT TEXT: Expected result: New Agent Oracle Home should not be registered with inventory
Actual Result: Agent Oracle Home with same value /u02/oracle/agent12c/core/12.1.0.2.0 exists
Check complete. The overall result of this check is: Failed <<<<

Has anyone seen this before?


Thanks,
Leighton

    This is because you are trying nfs agent on same host on which you have deployed the first agent.Please try on another host

    Hi Nelson, as Nazim mentioned, how did you install the first agent ? If you are planning to install nfs agent on 2 node rac then make sure that you donnt have an existing 12c agent on these node, else you will get a pre-req warning that agent is already deployed. You can choose to ignore it and move forward as well. Let me knwo if this i snot clear to you or not working.
    Also if it fails durther you can drop me an email with logs.

    Hi Akanksha,
    The NFS agent is being installed on a different host with no existing agent. I'll remove the master agent and retry the deployment. I'll send you the logs via email also.

    Thanks,

    I upgraded the NFS agents to 12.1.0.3.0 but there were some errors encountered during the upgrade. It wasn't properly detecting the correct agent version so I uninstalled the shared agent only. Now I'm attempting the re-install the agent using silent install approach.

     

    The master agent is already installed and I'm attempting to create the plugin list using the master agent but its failing.

     

    $AGENT_HOME/perl /u02/oracle/agent12c/core/12.1.0.3.0/sysman/install/create_plugin_list.pl -instancehome /u02/oracle/agent12c/agent_inst

    The agent Base Dir is

    Creating file : /rwFile

    The plugin file cannot be created.

    Make sure the  has write permission

     

    It appears to be using the incorrect agent Base directory.

     

    ./emctl getproperty agent -name agentBaseDir

    Oracle Enterprise Manager Cloud Control 12c Release 3

    agentBaseDir=/u02/oracle/agent12c

     

    Any thoughts?

     

     

    Thanks,

    Leighton
