System Monitoring Plug-in Installation Guide for EMC Celerra Server

10g Release 2 (10.2)


January 2006

This document provides a brief description about the Oracle System Monitoring Plug-in for EMC Celerra Server, details on the versions the plug-in supports, prerequisites for installing the plug-in, and step-by-step instructions on how to download, install, verify, and validate the plug-in.


The System Monitoring Plug-in for EMC Celerra Server extends Oracle Enterprise Manager Grid Control to add support for managing EMC Celerra Network Attached Storage (NAS) servers. By deploying the plug-in in your Grid Control environment, you gain the following management features:

Versions Supported

This plug-in supports the following versions of products:


The following prerequisites must be installed before you can deploy the plug-in:

Deploying the Plug-in

After you ensure that the prerequisites are met, follow these steps to deploy the plug-in:

  1. Download the EMC Celerra Server Plug-in archive to your desktop or computer on which the browser is launched. You can download the archive from the Oracle Technology Network (OTN).

  2. Log in to Enterprise Manager Grid Control as a Super Administrator.

  3. Click the Setup link in the upper right corner of the Grid Control Home page, then click the Management Plug-ins link on the left side of the Setup page.

  4. Click Import.

  5. Click Browse and select the plug-in archive:

  6. Click List Archive, which lists the plug-ins from the selected archive.

  7. Select the plug-in and click OK.

  8. Verify that you have set preferred credentials on all Agents where you want to deploy the plug-in.

  9. In the Management Plug-ins page, click the icon in the Deploy column for the EMC Celerra Server plug-in. The Deploy Management Plug-in wizard appears.

  10. Click Add Agents, then select one or more Agents to which you want to deploy the plug-in. The wizard reappears and displays the Agent you selected.

  11. Click Next, then click Finish.

    If you see an error message stating that the preferred credential is not set up, go to the Preferences page and add the preferred credentials for the Agent target type.

Adding Instances for Monitoring

After successfully deploying the plug-in, follow these steps to add the plug-in target to Grid Control for central monitoring and management:

  1. From the Agent home page where the EMC Celerra Server Plug-in was deployed, select the EMC Celerra Server target type from the Add drop-down list, then click Go. The Add EMC Celerra Server page appears.

  2. Provide the following information for the parameters:

    • Name — Name for the plug-in

    • Celerra Control Station Host or IP Address — Name/IP address of the Control Station

    • Celerra Admin User — Keep the default name if SSH set up for nasadmin, or change the name if SSH is set up for a different user

  3. Click Test Connection to make sure the parameters you entered are correct.

  4. Reenter the encrypted parameters from step 2 if the connection test was successful, then click OK.


After you deploy and configure the plug-in to monitor one or more targets in the environment, you can customize the monitoring settings of the plug-in. This alters the collection intervals and threshold settings of the metrics to meet the particular needs of your environment. If you decide to disable one or more metric collections, this could impact the reports that the metric is a part of.

Verifying and Validating the Plug-in

After waiting a few minutes for the plug-in to start collecting data, use the following steps to verify and validate that Enterprise Manager is properly monitoring the plug-in target:

  1. Click the EMC Celerra Server target link from the Agent home page Monitored Targets table. The EMC Celerra Server home page appears.

  2. Verify that no metric collection errors are reported in the Metrics table.

  3. Ensure that reports can be seen and no errors are reported by selecting the Reports property page.

  4. Ensure that configuration data can be seen by clicking the View Configuration link in the Configuration section. If configuration data does not immediately appear, click Refresh in the View Configuration page.

Configuring SSH to Bypass the Password

Follow the steps below to set up SSH from the host, where the Enterprise Manager Agent is installed on the EMC Celerra control station.

  1. Log in to the host where the Enterprise Manager Grid Control Agent is installed that monitors EMC Celerra. Log in as the user under which the Agent is running.

  2. Connect to the EMC Control Station using SSH as shown below. Ensure that the SSH client is installed on the host. If this is the first time you are accessing the Control Station, type Yes when the system asks whether you want to save the RSA key of the Control Station to the local file.

    # ssh -l nasadmin erpcel01-con 
    The authenticity of host 'erpcel01-con (' can't be established. 
    RSA key fingerprint is 72:2c:f8:db:76:c9:8d:35:ae:b1:ab:74:30:f5:69:af. 
    Are you sure you want to continue connecting (yes/no)? yes 
    Warning: Permanently added 'erpcel01-con,' (RSA) to the list of known hosts. 
    nasadmin@ erpcel01-con 's password: [Type the password for nasadmin]

    slot_0 primary control station ***  
    [nasadmin@erpcel01-con nasadmin]$ [Type exit and exit SSH]
  3. Generate a pair of authentication keys on the Agent host by entering:

    # cd ~/.ssh    
    # ssh-keygen -t dsa -f id_dsa 
    Generating public/private dsa key pair. 
    Enter passphrase (empty for no passphrase): [Leave empty] 
    Enter same passphrase again: [Leave empty] 
    Your identification has been saved in id_dsa. 
    Your public key has been saved in 
    The key fingerprint is: 
    e2:24:fa:d2:f9:48:e6:1e:85:7e:86:d1:b5:52:79:fb spanchum@
  4. Upload the public key ( to the Control Station in the home directory for user nasadmin.

    # scp nasadmin@erpcel01-con:~/.ssh/ 
    nasadmin@erpcel01-con's password: [Type the password for nasadmin] 100% |*************************************************| 600 00:00 
  5. Log in to the Control Station (erpcel01-con) and rename the uploaded file ( to the authorized_keys file. If the file already exists, add the contents of the file to the authorized_keys file by entering:

    # ssh -l nasadmin erpcel01-con 
    nasadmin@erpcel01-con's password: [Type the password for nasadmin] 
    Last login: Sat Oct 15 22:53:22 2005 from
    EMC Celerra Control Station Linux Thu Mar 24 08:27:43 PST 2005
    *** slot_0 primary control station *** 
    [nasadmin@erpcel01-con nasadmin]$ cd .ssh 
    [nasadmin@erpcel01-con .ssh]$ cat >> authorized_keys 
    [nasadmin@erpcel01-con .ssh]$ logout 
    Connection to erpcel01-con closed. 
  6. Run the following command to verify that a password is not required for any of the secure programs:

    # ssh -l nasadmin erpcel01-con date 
    Sat Oct 15 23:04:46 PDT 2005
