Hyperconverged Storage Pool - Scaling Out By Adding Additional MediaAgent Nodes

To scale out an existing storage pool, you can add additional MediaAgent nodes in the multiples of the Redundancy factor.

Before You Begin

  • Install the latest Service Pack on the CommServe host. For more information see, Service Packs.

Important: In case you have multiple Hyperconverged Storage Pools, change the Automatic Association to Manual Association for all the Hyperconverged Storage Pools other than the one that has to be scaled out.

  • In case you have multiple Hyperconverged Storage Pools configured, do the following:
    • Ensure that you know the exact Client Computer Group name of the Hyperconverged Storage Pool that has to be scaled out.
    • Ensure you have the Hostnames of the MediaAgent nodes that you plan to add to the storage pool.
    • Set filters to ensure that the existing and the to be added MediaAgent nodes are selected based on the Hostname.


Following are the high-level processes required to add additional MediaAgent nodes and involves the following tasks in the order listed:

  1. Ensure that you have all the prerequisites configured. For more information see, Prerequisites for Manually Setting Up the Hyperconverged Storage Pool.
  2. On all the Linux servers that have to be added as the additional node, install the MediaAgent and the Storage Pool.

    For more information, see Installing the MediaAgent.

    Important: You must configure at least 3 MediaAgent nodes to configure a Storage Pool.

  3. After all the MediaAgent nodes are registered, verify the default configurations. For more information see, Verifying the Default Configurations.
  4. On the CommCell Console, by default 5% of the total disk space or 2 TB (which ever is lower) is set as the Reserve Space on the Mouth Path Properties > Allocation Policy tab

    For example: If you have 100 TB of disk storage, 2 TB will be reserved.

  5. Verify from the Hyperconverged Storage Pool's Client Computer Group Properties that the newly added MediaAgent nodes are automatically added to the existing Hyperconverged Storage Pool.
