Unable to reload N7k switch using ansible after upgrade

[swattik]

Hello Experts,

I'm trying to reboot one of my n7k using ansible but unable to do it. Tried all the possibilities but no luck. Can any one here please help me out in this matter.

- name: Save and Reload the N7k

  hosts: n7k

  gather_facts: no

  tasks:

 #   - name: Save the config and verify current Boot variable

 #     nxos_command:

 #       commands:

 #         - copy running-config startup-config vdc-all

 #         - show boot

 #     register: new_boot

 #   - debug: var=new_boot.stdout_lines

# Reload the Nexus

    - name: Reload the Nexus Switch

      nxos_command:

        commands:

          - reload

        prompt: "This command will reboot the system. (y/n)?  [n]"

 #       provider: {{ cli }}

 #   - nxos_command:

 #       commands:

 #         - reload

#          - command: y

 #       check_all: true

 #   - nxos_command:

 #       prompt: This command will reboot the system. (y/n)?

 #         - answer: y

    - name: Wait for 1500 seconds

      wait_for_connection:

        delay: 90

        timeout: 1000

This looks good @swattik i made a couple of changes, firstly in Reload the nexus switch task, where I added the response: "y" parameter to the nxos_command module, so this tells ansible to respond with "y" when prompted to confirm the reload. I also removed the unnecessary provider and check_all parameters, as well as the duplicate nxos_command tasks too. Let me know how this goes, i do not have a devices to try this on atm.

Hope this helps.

Hi @bigevilbeard Thanks for your quick response. I've tried your play but unfortunately getting similar kind of response.

Play :

    - name: Reload the Nexus Switch
      nxos_command:
        commands: 
          - reload
        prompt: This command will reboot the system. (y/n)?  [n] y
        response:  "y"

Error:
{
"msg": "Unsupported parameters for (nxos_command) module: prompt, response Supported parameters include: auth_pass, authorize, commands, host, interval, match, password, port, provider, retries, ssh_keyfile, timeout, transport, use_ssl, username, validate_certs, wait_for",
"invocation": {
"module_args": {
"commands": [
"reload"
],
"prompt": "This command will reboot the system. (y/n)? [n] y",
"response": "y"
}
},
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"_ansible_no_log": false,
"changed": false
}

@swattik sorry thats my fault, prompt and response parameters are not supported by the nxos_command module, try this way with the expect parm, hopefully this is supported!

Hello @bigevilbeard , tried the play you have shared above, but unfortunately getting same error, seems the module doesn't support by NXOS. Below the error msg.

fatal: [x,x,x,x]: FAILED! => changed=false
ansible_facts:
discovered_interpreter_python: /usr/bin/python

@swattik surprised that is not supported, ok so.. looks like the main issue is that nxos_command module doesn't natively handle interactive prompts like the reload confirmation. This is a bit of change in approach, but wonder if this solves the issue? I have seen a few threads in the past with the prompts being a blocker for automation and it can be hard to handle these.

@swattik ok, good this is getting closer, this error appears to be that the wait_for condition is being applied within the nxos_command - see if splitting this into two tasks helps....

- name: Reload Nexus 7K Switches with Improved Confirmation Handling
  hosts: n7k
  gather_facts: no

  tasks:

    - name: Save Configuration and Check Boot Variables
      nxos_command:
        commands:
          - copy running-config startup-config vdc-all
          - show boot
      register: new_boot

    - name: Display Boot Variables (Optional - for debugging)
      debug:
        var: new_boot

    - name: Initiate Switch Reload
      nxos_command:
        commands:
          - reload

    - name: Confirm Reload Prompt
      nxos_command:
        commands:
          - y    # Send 'y' to confirm the reload

    - name: Wait for Reload Confirmation
      nxos_command:
        commands:
          - show logging logfile | include reload
      register: reload_log
      until: reload_log.stdout.find("Proceed with reload") != -1
      retries: 10
      delay: 5

    - name: Wait for Switch to Go Offline
      wait_for:
        host: "{{ inventory_hostname }}"
        port: 22
        state: absent
        delay: 30
        timeout: 600

    - name: Wait for Switch to Come Back Online
      wait_for:
        host: "{{ inventory_hostname }}"
        port: 22
        state: present
        delay: 60
        timeout: 1200

[swattik · Accepted solution]

Finally, Issue got resolved, Hurrey... @bigevilbeard you can use below module to reboot any NXOS device.

---
- name: Save and Reload the N7k
   hosts: n7k
   gather_facts: no

   tasks:

      - name: Reload the Nexus Switch
         nxos_reboot:
            confirm: true

Awesome, congrats!

Thank you so much for your continuous support. Much appreciated.
