You can remove a high availability (HA) cluster in the Clusters tab of the Broker VMs page.
When removing a cluster, the cluster is disassembled and the cluster object is deleted. All nodes in the cluster are reverted back to standalone Broker VMs with their settings reset to default as a newly created Broker VMs.
If you've configured load balancing for any "active/active" applets configured, you need to update your Load Balancer configuration settings to stop sending logs to these Broker VM nodes.
You cannot remove a cluster that is used as a download source from which the Cortex XDR agents retrieve release upgrades and content updates. You'll need to change the cluster's current designated role before removing a cluster.
Select→ → → .
In the Clusters tab, right-click a cluster, and select Remove Cluster.
Follow the instructions in the REMOVE CLUSTER window, whose instructions differ depending on the type of cluster you are trying to remove, and Remove the cluster.
