Remove Edge Nodes from an NSX Edge Cluster

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.

Procedure

1. In the navigation pane, click Inventory > Workload Domains.
2. In the Workload Domains page, click a domain name in the Domain column.
3. Click the Edge Clusters tab.
4. Click the vertical ellipsis menu for the Edge Cluster you want to expand and select Shrink Edge Cluster.
5. Select the Edge node(s) to remove and click Next.
6. Review the summary and click Next.
   SDDC Manager validates the request.
7. If validation fails, use the Back button to edit your settings and try again.
   Note: You cannot remove the active and standby Edge nodes of a Tier-1 router at the same time. You can remove one and then remove the other after the first operation is complete.
8. If validation succeeds, click Finish to remove the NSX Edge node(s) from the NSX Edge cluster.
   You can monitor progress in the Tasks panel.
