1.0 Adding an Appliance to an Existing Deployment

You can add TeamWorks appliances to the TeamWorks system to accommodate additional load only if your original TeamWorks system was configured with shared storage (/vashare).

Do Not Mix Appliance Versions

It is critical to never allow mixed-version appliances to service user requests in the same deployment.

If mixed versions are allowed to service user requests, a full reindex of the system might be required to restore service stability.

Follow the instructions in this section exactly to avoid mixed-version problems.

Prerequisites

You can add TeamWorks and Search appliances to an existing TeamWorks deployment only if your TeamWorks deployment meets the following prerequisites:

  • It is not an all-in-one TeamWorks deployment: All-in-one TeamWorks deployments cannot be expanded.

  • The NFS mount is accessible to all appliances: All TeamWorks appliances in the cluster need to have access to the NFS mount.

  • (Recommended) A load balancing solution is in place: If you want to provide a common access URL for all your TeamWorks users, you must provide a solution for load balancing between the TeamWorks appliances.

    Micro Focus does not provide a load balancing appliance; however, there are many software solutions available, such as Apache, HAProxy, and NGinx.

    There are also hardware solutions available, such as F5 Networks, Juniper, Riverbend, and A10 Networks.

    Searching the web for Layer 4-7 switches or Application Delivery Controller is a good place to start finding a solution that meets your requirements.

Adding 18.2 Search Appliances to an Existing Deployment

To add Search appliances to an exiting large TeamWorks deployment:

  1. Ensure that your system meets the necessary prerequisites.

  2. Assuming that you have planned the installation, downloaded the software, and so on, install the additional Search appliance, beginning with Setting Up Subsequent Search Appliances in the GroupWise TeamWorks 18.2.1: Installation and Deployment Guide.

    IMPORTANT:Choose the same configuration options (including the same NFS mount) that you chose when you installed the original Search appliance.

  3. Run the installation wizard for a multiple-appliance deployment (at port 9443), as described in Setting Up Subsequent Search Appliances in the GroupWise TeamWorks 18.2.1: Installation and Deployment Guide.

  4. Restart each TeamWorks appliance to ensure that the entire TeamkWorks system is synchronized.

Adding 18.2 TeamWorks Appliances to an Existing Deployment

To add a TeamWorks appliance to an exiting large TeamWorks deployment:

  1. Ensure that your system meets the necessary prerequisites.

  2. Assuming that you have planned the installation, downloaded the software, and so on, install the additional TeamWork appliance, beginning with Creating the TeamWorks Virtual Machines in the GroupWise TeamWorks 18.2.1: Installation and Deployment Guide.

    The process is the same as when you installed the original TeamWorks appliances.

    IMPORTANT:Choose the same configuration options (including the same NFS mount) that you chose when you installed the original TeamWorks appliances.

  3. Run the installation wizard for a multiple-appliance deployment (at port 9443), as described in Setting Up the TeamWorks Appliances in the GroupWise TeamWorks 18.2.1: Installation and Deployment Guide.
