Decommisson appliance and reuse hostname and IP address

[Anonymous]

I'd like to know the proper procedure for decommissioning an appliance (in my case, New Health and Wellness) so that I can reuse the existing IP address and hostname.

Thanks.

Hi Jeremy,

Please follow the steps below to decommission a host.

1. Remove the host from UI.

2. Find the UUID of the removed host.

SSH to the host and run 'cat /etc/salt/minion'

3. Remove the key using orchestration-cli-client from the Admin server.

SSH to the the Admin server then run the following command.

orchestration-cli-client --remove-key <UUID noted in step #2>

salt-key |grep <UUID noted in step #2>  -- to confirm the key is removed.

If the key still exists, try running the following command.

salt-key -d <UUID noted in step #2>

Type 'y' when asked.

4. Remove the federations from the Admin server.

rabbitmqctl clear_parameter -p /rsa/system federation-upstream carlos-upstream-<UUID noted in step #2>

Thanks.
