Objective

Unlike other Public Cloud Instances where the rescue mode can be activated from the OVHcloud Control Panel, this option is not yet available for Metal Instances. To activate the rescue mode on a Metal Instance, you must go through the command line interface. This can be done via Openstack.

This guide explains how to activate the rescue mode on a Metal Instance via CLI.

This guide applies only to Metal instances. To access rescue mode for all other instance types, follow this main guide.

Requirements

Instructions

Before following these steps, it’s recommended that you first complete the following:

Putting a Metal instance in rescue mode using OpenStack CLI

Once your environment is set, establish an SSH connection to your instance and run the following command to list your existing Instances:

#root@server:~$ openstack server list

+--------------------------------------+-----------+--------+--------------------------------------------------+--------------+
| ID                                   | Name      | Status | Networks                                         | Image Name   |
+--------------------------------------+-----------+--------+--------------------------------------------------+--------------+

+--------------------------------------+-----------+--------+--------------------------------------------------+--------------+

Once you have retrieved the ID of the instance, run the following command to reboot the instance in rescue mode:

openstack server rescue f12124f8-c058-4ee7-8b89-5a732ca8079b --password "csdsdf6dKcj5"
