OS / Environment

Ansible server: CentOS Junos: 15.1X53-D59.3 Device: EX2300-48

Summary

The update process fails after updating the master in an virtual chassi with 4 members, when member 0 is not the master. It works fine when you force member 0 to be the master first.

Steps to reproduce

1. Set up a virtual chassi with 4 memebers
2. Make member 1,2 or 3 master. Not member 0.
3. Update the switch using Ansible

- name: Perform a Junos OS software upgrade
  hosts: juniper
  roles:
    - Juniper.junos
  connection: local
  gather_facts: no

  vars:
    wait_time: 3000
    local_dir: /var/testing/software
    OS_version: 15.1X53-D59.3
    OS_package: junos-arm-32-15.1X53-D59.3.tgz
    log_dir: /var/testing/playbooks/log

  tasks:
    - name: Perform update
      juniper_junos_software:
        local_package: "{{ local_dir }}/{{ OS_package }}"
        reboot: false
        logfile: "{{ log_dir }}/ansible.log"

Expected results

A normal update with no reboot and that the "show version" command shows 4 pending installs.

Actual results

The ansible playbooks fails. The "show version" command shows only a few pending installs. It shows pending installs for every member with a higher member id then the master and for the master.
