This blog includes installation of SAP S/4HANA 2021 FPS2 and will focus on creating Sandbox type instance with co-deployed (embedded) gateway.

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 rev56
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
SAP Note 2945239 – SAP HANA Platform 2.0 SPS 06 Release Note
SAP Note 3150702 – SAP HANA 2 SPS06 Revision 062.00   <= Current at S/4HANA 2021 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_062_0-80002031.SAR available along with SAP HANA  Client IMDB_CLIENT20_012_25-80002082.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 S4CORE106_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/SWPM20SP12_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_Plan_2001306249_20220525_.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_1001290107_20211013_.xml
This is ok for sandbox.

As we executed combined SWPM+SUM you should have filesystem /usr/sap/S4H/SUM and you should directly jump to url https://vhcals4hci:1129/lmsl/sumabap/S4H/doc/slui

If not, don’t worry, please extract it as below 2 commands:

cd /usr/sap/S4H
SAPCAR -xvf /sapmedia/download/SUM20SP14_0-80002456.SAR
as root
ps –ef | grep –i sapup
