How to Decommission a Node

Use this procedure also in cases when a provisioning operation failed.

1. Set the node to a deleted state.

   # ironic node-set-provision-state $NODE deleted

2. Display the node's information.

   In the following example, the properties with asterisks (*) indicate the deleted state of the node.

   # ironic node-show $NODE

3. If you are troubleshooting a failed provisioning process, validate the node's fields.

   Problems with any of the driver_info elements that were specified for the node are identified under Reason column.

   # ironic node-validate $NODE
   +------------+--------+---------------+
   | Interface  | Result | Reason        |
   +------------+--------+---------------+
   | console    | None   | not supported |
   | deploy     | True   |               |
   | management | True   |               |
   | power      | True   |               |
   +------------+--------+---------------+
