Run Powervault_template via CLI

  1. Verify that /opt/omnia/powervault_inventory is created and updated with all powervault IP details. This is done automatically when control_plane.yml is run. If it’s not updated, run ansible-playbook collect_device_info.yml (dedicated NIC) or ansible-playbook collect_node_info.yml (LOM NIC) from the control_plane directory.
  2. Run ansible-playbook powervault.yml -i /opt/omnia/powervault_inventory

Run Powervault_template on the AWX UI.

  1. Run kubectl get svc -n awx.
  2. Copy the Cluster-IP address of the awx-ui.
  3. To retrieve the AWX UI password, run kubectl get secret awx-admin-password -n awx -o jsonpath="{.data.password}" | base64 --decode.
  4. Open the default web browser on the control plane and enter http://<IP>:8052, where IP is the awx-ui IP address and 8052 is the awx-ui port number. Log in to the AWX UI using the username as admin and the retrieved password.
  5. Under RESOURCES -> Templates, launch the powervault_template.
