update_all_inventory.yml

---
#
# Summary: Auto generate (or update) the Ansible inventory file with all servers (Name and Moid or each discovered server)
#
# The hosts group used is provided by the group variable or defaulted to 'Intersight'.
# You can specify a specific host (or host group) on the command line:
#   ansible-playbook ... -e group=<your host group>
#   e.g., ansible-playbook server_profiles.yml -e group=TME_Demo
#
# This playbook only runs once (and not for each server in the inventory), but the hosts group is used to get API key info
#
