Installing a Remote Acquisition Unit

Contributors netapp-alavoie

You can install one or more Remote Acquisition Units (RAUs) in your OnCommand Insight environment. Acquisition units run in the network that accesses (through modules called data sources) and collect data from different devices in the data center.

Before you begin

You must have completed all of the installation prerequisites.

At least one port must be open and available between the RAU server and the OnCommand Insight Server to forward change information to the server. If you are unsure about this, validate it by opening a Web browser on the RAU computer and directing it to the OnCommand Insight server:

 https://< OnCommand Insight Server hostname >:< acquisition_port >

The acquisition port defaults to 443, but it might have changed during the server installation. If the connection is successful, you see a OnCommand Insight response page, indicating an open and available port between the RAU and the OnCommand Insight server.

For environments using Network Address Translation or Port Address Translation (NAT/PAT: i.e, any translation of IP addresses), Insight only supports insertion of an RAU between NAT and the Device.

  • Supported: OnCommand Insight -> NAT -> RAU -> Device

  • Unsupported: OnCommand Insight -> RAU -> NAT -> Device

Steps

  1. Log in to the RAU server using an account with sudo privileges.

  2. Navigate to the directory on the server where the installation files are located and type the following command:

    unzip oci-rau-<version>-linux-x86_64.zip

  3. You can view syntax, command arguments, and parameter usage for oci-install.sh:

    sudo ./oci-rau-<version>-linux-x86_64/oci-install.sh --help

  4. Run the installation script:

    sudo ./oci-rau-<version>-linux-x86_64/oci-install.sh

  5. Read the License Agreement, accept it, and then follow the prompts.

    After you answer all the prompts, the installation begins and should take approximately 10 minutes, depending on the applications installed.

If your data begins acquiring, you are all set; you do not need to synchronize the Server and RAU as noted below.

Synchronize Server and RAU

Important If data does not begin acquiring after installing the Remote Acquisition Unit, synchronize the RAU with the OnCommand Insight Server. Follow these steps:

  1. On the OnCommand Insight Server system, start the SecurityAdmin tool in interactive mode

    securityadmin -i

  2. Change the password for the acquisition user for the Insight Server to a password of your choice. Make note of this password as you will require it below.

  3. Restart the server/LAU.

  4. On the Remote Acquisition Unit (RAU) system, start the SecurityAdmin tool in interactive mode. You will need the password you noted from step 2 above.

    securityadmin -i

  5. Change the password for the acquisition user to the password used in step 2.

  6. Restart the RAU.
