Remove appliance (svc_remove_appliance)

This service script enables you to remove an appliance from the cluster without migrating existing data or workloads. When you run the script, it displays the associated storage resources and workloads for the appliance you specified.

NOTE:Run this script only on the master node.

Migrate the relevant storage resources and workloads to another appliance before removing it from the cluster. If there are data protection operations in progress, the script is unable to remove the appliance. However, the script enables you to stop any replication operations.

CAUTION:
  • Removing the appliance using this script is not an ideal use case. Ensure that you really want to remove the appliance.
  • This script not only removes the appliance, but also resets it back to original factory settings and shuts it down.
  • Although the IP addresses assigned to the appliance remain with the cluster and are marked as unused, all data is removed.
  • The script does not block user commands or actions. Ensure that users are notified not to create any storage resources or virtual machines when you begin migrating data off the appliance. If new storage resources and virtual machines are created during this operation, the workloads may get placed on the appliance you are trying to remove.

Ensure that all relevant storage resources and workloads are migrated to another appliance before you proceed.

You cannot remove a master appliance. See the Knowledgebase article - HOW17166 for more information.
