Configure Replication Network on Air Gap Cluster

Perform the following steps on each node in the Air Gap 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 IRE and select the network interface that is configured for IRE.

   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. Edit HyperScale X network configuration file:

   /etc/CommVaultRegistry/Galaxy/Instance001/MediaAgent/.hyperscalenw.cfg
   

4. Delete commServeRegistration and rename dataProtection to commServeRegistration.

   For example:

   Before:

   [network_types]
   bond1 = commServeRegistration
   bond2 = storagePool
   bond3 = dataProtection
   

   After:

   [network_types]
   bond2 = storagePool
   bond3 = commServeRegistration
   

   /// note | Note

   Actual bond or interface name on the node may be different. Make sure you use the correct interface.

   ///

5. Restart services using the following commands:

   systemctl restart network
   commvault start
