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 -c set -t appliance -m extender
3. Follow the instructions to set a new chassis id for the extender chassis.
   This function updates the chassis id on all hosts, and hard resets the FortiAnalyzer-BigData system.
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 -c show -t members
   There should be 12 additional hosts added as members. Wait until all the hosts' status shows as Joined.
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.
