Chapter 3. RHEL System Roles for SAP

Procedure

1. Create a file named sap-hana.yml with the following content:

   ---
   
   - hosts: localhost
     vars:
       ansible_connection: local
       sap_general_preconfigure_max_hostname_length: 64
       sap_general_preconfigure_reboot_ok: false
       sap_general_preconfigure_fail_if_reboot_required: false
       sap_hana_preconfigure_reboot_ok: false
       sap_hana_preconfigure_fail_if_reboot_required: false
       sap_hana_preconfigure_update: true
     roles:
       - sap_general_preconfigure
       - sap_hana_preconfigure

   Important

   The correct indentation and the use of spaces instead of tabs is essential for YAML files.

   Note

   The line sap_general_preconfigure_max_hostname_length: 64 is only required if your hostname (hostname -s) is longer than 13 characters and if you are not using this system for an SAP ABAP Platform instance. Without this line, the role sap_general_preconfigure will fail its hostname check because a hostname with more than 13 characters is not allowed for an SAP ABAP Platform instance as per SAP note 611361.

2. Run the sap-hana.yml Ansible playbook:

   # ansible-playbook sap-hana.yml -e 'ansible_python_interpreter=/usr/libexec/platform-python'

   This will configure this system according to the applicable SAP notes for SAP HANA on RHEL 9.

3. After the ansible-playbook command has finished successfully, reboot the system:

   # reboot
