Configure Replication Network on Source Cluster

The source environment can be either a HyperScale X cluster or a non-HyperScale X setup.

Ensure that a dedicated network for Vault replication is configured on the source side. This includes configuring the appropriate VLAN, network ports, and interfaces. The customer is responsible for setting up and maintaining this dedicated replication network according to Air Gap design requirements.

If the source is a HyperScale X cluster, perform the following steps on all source nodes:

Note

Unlike the Air Gap cluster, you do not need to modify the .hyperscalenw.cfg file on the source cluster.

Step 1: Configure Network Interfaces

  1. Connect to the node using IPMI console.

  2. Launch the HyperScale X network configuration tool:

    ./cvhsx_launch_nwconfig.sh
    3. Add a Data Protection Network.

    While configuring the Data Protection Network, ensure that you use the VLAN dedicated for Vault replication and select the network interface that is configured for Vault replication.

    The replication network supports all types of interfaces, including a single network port, bonded interfaces, and VLAN-tagged interfaces.

  3. Apply changes and exit.

Step 2: Update Firewall and Services

  1. Reconfigure firewall to add the replication interface to the block zone.

  2. Stop Commvault services:

    commvault stop

  3. Restart services:

    systemctl restart network
commvault start
