How to scale out

You can scale out by adding more extender chassis.

The following operation removes all user data from the extender chassis.

To add an extender chassis

1. On the extender chassis, power off Blade A1 via the CMM (see Connect to the Chassis Management Module).

   Do not connect the links between both chassis until step 2 has been successfully completed; otherwise, it may cause an IP conflict and corruption in the distributed consensus.

2. On the extender chassis, access the Security Event Manager Controller (see To connect to the Security Event Manager Controller:) and run the following command:
   

   fazbdctl set appliance {chassis_id}

   The chassis ID is an integer starting with 1, where 1 is the default chassis ID of the cluster formed by one chasis. If you are adding the first extender to a cluster with one chassis, the chassis_id of the extender should be set to 2. You should increment this chassis_id as you stack more chassis to the cluster. For example, the second extender’s chassis_id should be set to 3 before you connect it to a cluster of two chassis. This function updates the chassis id on all hosts, and hard resets the FortiAnalyzer-BigData system.

   Wait for the command to finish running without errors before you proceed with the next step.

3. Power off Blade A1 in the extender chassis from CMM.
4. Connect the 40GE links with QSFP between the Internal Switch Modules (Switch Module #1) of the extender and main chassis.
5. On the main chassis, access the Security Event Manager Controller and run the following command to make sure the new hosts have been added:
   fazbdctl show members
   There should be 12 additional hosts added as members. Wait until all the hosts' status shows as Alive.
6. Access the FortiAnalyzer-BigData GUI of the main chassis, and go to Cluster Manager > Hosts.
7. Click Assign Role to assign the newly added hosts.

   New hosts should have a "new" label.

8. Wait for the "Assign" job to complete for all services to become healthy.
9. Recommended. After scaling out, rebalance the data across the cluster.
   1. Go to Cluster Manager > Services and stop the Core Services Group.
   2. Go to Cluster Manager > Jobs and click Create Custom Job.
   3. From Template, select Data Rebalance (All) and click Create.
   4. In the Jobs table, click Run beside to the created Job.
   5. When the job is finished, go back to Services and start the Core Services Group.
