This documentation explains how Ansible role can be used for starting InfoScale services on the cluster nodes after an upgrade.

The goals of this guide is to start services on the cluster nodes of InfoScale after an upgrade.

Pre-requisites

  • Ansible control node is properly set to run Ansible playbooks.

  • The role is installed or copied as per your environment

Role information

The role can be used like this:

```yaml
---
- name: My playbook for InfoScale tasks
  hosts: cluster_nodes
 
  roles:
    - upgradestart_processes
```

This role should be used when the user wants to start the services on the cluster nodes of InfoScale.

There are several ways of modifying the default variables. You can check the Ansible documentation for more information.

Dependencies

This role internally has dependencies on the following roles which are defined in meta/main.yml:

  • role: get_host_info

  • role: set_infoscale_facts

The get_host_info and set_infoscale_facts roles compliment the start_processes role to have recent information from the cluster node before starting the services.

This role can be included in the playbook as per the user's environment workflow or requirements. The playbook can be run as below:

From the command line, it can be done with the -e EXTRA_VARS or --extra-vars EXTRA_VARS flag:

```cli
ansible-playbook -i hosts playbooks/myinfoscale.yml -e "vtas_component='sfha'" -e 
"vtas_product='ENTERPRISE'" -e "vtas_product_version='sfha'"

Role usage

This role can be used in the playbooks in all the ways Ansible supports. The following is the example of how to import this role.

```yml 
 
 - name: Starting processes 
    import_role:
      name: upgradestart_processes
