This blog includes installation of SAP S/4HANA 2020 FPS2 and will focus on creating Sandbox type instance with co-deployed (embedded) gateway.
Please find other blogs as follows at S/4HANA SQUARE ONE
This is the Video for installation of SAP S/4HANA 1909 FPS0 (Not 2020 FPS2 but process is similar):
STEP 1: OPERATING SYSTEM
It is recommended to install SuSE Linux or RedHat Linux8. Refer
SAP Note 2235581 – SAP HANA: Supported Operating Systems.
SAP Note 2399995 – Hardware requirement for SAP HANA 2.0
SAP Note 2620910 – SAP S/4HANA 1511, 1610, 1709 and SAP BW/4HANA 1.0: Recommended Application Server Platforms
SAP Note 2777782 – SAP HANA DB: Recommended OS Settings for RHEL 8
SAP Note 2684254 – SAP HANA DB: Recommended OS settings for SLES 15 / SLES for SAP Applications 15
You can check your operating system version as below:
sid-hdb-s4h:~ # cat /etc/os-release
NAME="SLES"
VERSION="15-SP1"
VERSION_ID="15.1"
PRETTY_NAME="SUSE Linux Enterprise Server 15 SP1"
STEP 2: SAP HANA DATABASE
It is recommended to install minimum SAP HANA 2.0 SP05 rev52
SAP Note 2655761 – SAP S/4HANA – restrictions and recommendations regarding specific revisions of SAP HANA database for use in SAP S/4HANA
SAP Note 2844322 – SAP HANA Platform 2.0 SPS 05 Release Note
3021026 – SAP HANA 2 SPS05 Revision 055.00 <=Current at FPS2 release
SAP Note 2423367 – Multitenant database containers will become the standard and only operation mode
SAP Note 2469025 – How-To: Upgrading to SAP HANA 2.0
We will install HANA database through SWPM. So you need to have the SAR file IMDB_SERVER20_055_0-80002031.SAR available along with SAP HANA Client IMDB_CLIENT20_007_26-80002082.SAR
After S/4HANA and HANA Database are installed please follow SAP Note 2600030 – Parameter Recommendations in SAP HANA Environments for parameter recommendations. This note contains check scripts which detect SAP HANA version, SAP product installed, etc. and give specific parameter recommendations.
TIP: Please change the log mode if you don’t want to be spend time on log maintenance: In HANA studio –> Configuration –> global.ini –> persistence and set the parameter log_mode to overwrite. When you change the log mode, you must restart the database system to activate the changes. It is also recommended that you perform a full data backup. You can also set the log_mode to ‘overwrite’ using the following SQL-Statement:
ALTER SYSTEM ALTER CONFIGURATION ('global.ini', 'SYSTEM') SET ('persistence', 'log_mode') = 'overwrite' WITH RECONFIGURE;
STEP 3: SAP S/4HANA INSTALLATION USING SWPM
TIP: You don’t need to extract the backup zip files S4CORE105_INST_EXPORT_*.zip. SWPM tool will extract them into /usr/sap/HDB/HDB02/backup/data/DB_HDB. Ensure sufficient space of 100GB is available in this folder.
We will use the procedure for SWPM+SUM combined installation and you don’t need the SYSTEM/DDIC password from backup Database/ABAP instance.
Extract the SWPM SAR file as below
sid-hdb:/ # cd /install sid-hdb:/install # /sapmedia/SAPCAR -xvf /sapmedia/download/SWPM20SP08_0-80003424.SAR
You should get message at the end of this that SAPCAR: … files(s) extracted
Execute SWPM to do system copy with backup restore as below:
sid-hdb:/install#./sapinst SAPINST_USE_HOSTNAME=vhcals4hci SAPINST_ACCEPT_INTERNAL_SIGNATURE=true SAPINST_STACK_XML=/sapmedia/download/MP_Stack_1001203027_20210525_.xml
TIP: At this point if you get the screen below: 
Please refer SAP Note 2510478 Data unit /xx/xx/xx/SWPM is not signed with an official SAP signature.
SAP Note 2600047 – SAPINST_SLP_MODE=false and SAPINST_USE_XML don’t work together
I started with command: ./sapinst SAPINST_USE_HOSTNAME=vhcals4hci SAPINST_ACCEPT_INTERNAL_SIGNATURE=true SAPINST_STACK_XML=/sapmedia/download/MP_Stack_1001139968_20210224_.xml
This is ok for sandbox.
