SAP-as-a-Service with OpenStack Cloud – Part 3: S/4HANA HEAT Template
This content was based on work originally carried out by Phani Arava from SAT Infotech.
In the previous blog entry, we looked into building a HEAT template for HANA Instances.
In this part of the series SAP-as-a-Service with OpenStack Cloud, we will build-up on the previous HEAT template to create a S/4HANA Instance (S/4HANA 1511 SR1)
The S/4HANA HEAT Template should automate the following:
- Use a SUSE for SAP Image
- Take the inputs for the S/4HANA system (Instance Size: Small, Medium and Large)
- Create two servers: HANA System and S/4HANA Primary App Server
- Block Attachments from different Volume Types, size varies again based on the Instance Size to both the HANA System and the primary application server
- Create Mount Points for HANA Server based on the SID Inputs (HANA Server)
- Create Mount Points for S/4HANA App Server based on SID Inputs (HANA Server)
- Create mount point for HANA Installer (HANA server)
- Download the HANA Installer from a repo (This needs to be created prior) (HANA Server)
- Do an unattended installation of HANA Server
- Create a mount point for SAP Installation Dump (Primary S/4HANA server)
- Download the SWPM and inifile.params template from a repo (This needs to be created prior) (Primary S/4HANA Server)
- Do an S/4HANA Unattended Installation (Primary S/4HANA Server) SAP Note : 2230669
HEAT Stack Inputs
Once you launch the stack, the necessary operations start orchestrating. We have to wait till the Stack completely gets created.
The Complete Stack Operation should complete within 6-7 hours.
The HEAT Stack automates setting up of Volumes, the connection between the S4HANA server and completely sets up S4HANA.
The following HEAT template was used to achieve this:
