Enabling Firewall on HyperScale X Reference Architecture

Firewall can be enabled and the required ports automatically opened on the HyperScale nodes.

Firewall configuration divides the network into zones. A zone is a group of interfaces and services that share common rules to establish a secure boundary within the network and implement access control between the nodes. When you enable firewall, the CS registration and data protection interfaces are added to the default 'blocked' zone and the storage pool interface is added to a private 'cv_storage_ zone' in the firewall configuration.

Procedure

1. Set the MediaAgents associated with the cluster on Maintenance mode.

   For more information, see Setting the MediaAgent on Maintenance Mode.

2. Login to any one of the nodes in the storage pool.

   Note

   Firewall can be enabled on all the nodes in the storage pool from any one of the nodes. (It is not necessary to repeat the following steps from each node.)

3. Navigate the following folder:

   # cd /opt/commvault/MediaAgent/task_manager

4. Run the following script:

   # ./cvmanager.py -t Configure_Firewall

   This will enable the necessary ports needed for the cluster, depending on your environment. For more information on the required ports, see Firewall Port Requirements.

5. Verify that the firewall is enabled using the following command:

   # firewall-cmd --state

   This should display the state as running.

6. Verify that the MediaAgent services are running using the following command:

   # commvault list

   For more information on managing the MediaAgent services, see Commands to Control Services on UNIX Clients.

7. Check readiness of the MediaAgents in the HyperScale nodes to make sure that it is ready.

   For more information, see Checking Readiness.

8. Turn off the maintenance mode on MediaAgents associated with the cluster.

   For more information, see Setting the MediaAgent on Maintenance Mode.

Result

Firewall will be enabled in all the nodes in the storage pool.
