You can remove NSX Edge nodes from an NSX Edge Cluster that you created with SDDC Manager if you need to scale down to meet business needs.
For information about deleting an NSX Edge cluster, see KB 78635.
Prerequisites
- The NSX Edge cluster must be available in the SDDC Manager inventory and must be Active.
- The NSX Edge node must be available in the SDDC Manager inventory.
- The NSX Edge cluster must be hosted on one or more vSphere clusters from the same workload domain.
- The NSX Edge cluster must contain more than two NSX Edge nodes.
- The NSX Edge cluster must not be federated or stretched.
- If the NSX Edge cluster was deployed with a Tier-0 Service High Availability of Active-Active, the NSX Edge cluster must contain two or more NSX Edge nodes with two or more Tier-0 routers (SR component) after the NSX Edge nodes are removed.
- If selected edge cluster was deployed with a Tier-0 Service High Availability of Active-Standby, you cannot remove NSX Edge nodes that are the active or standby node for the Tier-0 router.
