Accidental Production Server Shutdown - Suse Linux Enterprise server for Sap Applications

Hi Team

This is my first post and hoping to contribute much in the future.
“I searched for this topic and posted the same query in SAP Support forum as well”

Our Customer using SAP S/4 HANA on AWS
Operating System - Suse Linux Enterprise server for Sap Applications - 15 SP 1 (Total of 16 EC2 Instances)

We chose the BYOS version, where the premier support isn’t included, it was all fine until customer faced an issue two months ago

Their Production Server has shut down automatically without any intimation, below is the log from AWS Console

  • They also had problems with auto failback during DR

“userAgent”: "aws-cli/1.18.117 Python/3.6.12 Linux/4.12.14-197.83-default

botocore/1.17.40" “userName”: “InstanceRole-HANA-DB-02”

Logs from OS with time stamp :

2022-02-23T12:13:48.984527+08:00 as4hana-hdp01 systemd-logind[3022]: Power key pressed.

2022-02-23T12:13:48.984753+08:00 as4hana-hdp01 systemd-logind[3022]: Powering Off…

2022-02-23T12:13:48.984875+08:00 as4hana-hdp01 systemd-logind[3022]: System is powering down.

When we reached AWS support, they directed us to SUSE to find the Root Cause Analysis and suggested to buy SUSE Premier Support

Is Premier support a mandatory to get this advanced support ?
Or is this something to do with SAP

Your expert advice is much appreciated
