Deleting a Gateway Host

Deleting a Gateway host completely removes it from the deployment. To delete one or more Gateway host(s):

Access the Gateway/Load Balancer screen (see The Gateway/Load Balancer Screen).
In the Gateway(s) Status table, either:
- Remove a single Gateway host by clicking the Delete icon (trash can) for the host you want to remove.
- Remove multiple Gateway hosts by selecting the affected hosts and then clicking the Delete button above the table.

HPE Ezmeral Runtime Enterprise removes the selected Gateway host(s).
