Template Creation for PowerVC

In this section you define the templates to run this demo.

Test your configuration

To check proper connection to your VCenter create the following template:

  1. Go to Resources -> Templates
  2. Click Add -> Add Job Template
  3. Add the following parameters
    • Name: tool - list diskimages
    • Inventory: your demo inventory
    • Project: your GitHub project
    • Playbook: tools/powervc/power_list_diskimages.yml
    • Credentials: OpenStack: PowerVC credentials
  4. Click Save
  5. Click Launch

If everything goes well you get a list of diskimages that are available in your environment.

There are some more playbooks like this in the tools directory of this repository to get information on the PowerVC environment. You can use these playbooks to figure out some of the variables that need to be configured in the inventory.

Set up the provisioning playbooks

Step 1

  1. Go to Resources -> Templates
  2. Click Add -> Add Job Template
  3. Add the following parameters
    • Name: 01 - provision Servers
    • Inventory: your demo inventory
    • Project: your GitHub project
    • Playbook: powervc/01-server-provisioning-power.yml
    • Credentials OpenStack: PowerVC Credentials
  4. Click Save

Step 2a

  1. Click Add -> Add Job Template
  2. Add the following parameters
    • Name: 02 - basic-os-setup (part1)
    • Inventory: your demo inventory
    • Project: your GitHub project
    • Playbook: powervc/02-basic-os-setup-subscription.yml
    • Credentials
      • OpenStack: PowerVC Credentials
      • Cloud: RHN Registration Credentials
      • SSH: Root Machine Credentials
  3. Click Save

Step 2b

  1. Click Add -> Add Job Template
  2. Add the following parameters
    • Name: 02 - basic-os-setup (part2)
    • Inventory: your demo inventory
    • Project: your GitHub project
    • Playbook: powervc/02-basic-os-setup-storage.yml
    • Credentials
      • OpenStack: PowerVC Credentials
      • Cloud: RHN Registration Credentials
      • SSH: Root Machine Credentials
  3. Click Save

Step 3 and 4

Repeat Step 2 with proper settings for the following playbooks in the powervc subdirectory:

  • 03-A-sap-hana-prepare.yml
  • 03-B-sap-hana-install.yml
  • 03-03-CD-sap-hana-cluster.yml (also needs PowerVC Credentials for unsupported Openstack fencing)
  • 04-A-sap-netweaver-prepare.yml
  • 04-B-S4-deployment.yml

Combine these job templates in a workflow template:

  1. Click Add -> Add Workflow Template
  2. Add the following parameters
  • Name: 00 - End-2-End S/4 HANA deployment
  • Inventory: your demo inventory
  • Project: your GitHub project
  • Variables: (adopt the variables to your needs)

This setup assumes a preconfigured DNS server with static names(see Prerequisites)
