SAP license verification fails after upgrade to SLES12 SP5 due to system UUID change

This document (000019647) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 12 SP5
SUSE Linux Enterprise Server 12 SP5 for SAP

Situation

After an upgrade to SLES12 SP5, alphabetic characters in /sys/devices/virtual/dmi/id/product_uuid are switched to lower-case whereas previous SLES versions use upper-case characters in the UUID string. 
This may impact case-sensitive tools that read this UUID, such as SAP license registration/verification checks.

Resolution

For those customers impacted by this issue before the patch is reverted, a PTF may be obtained from SUSE via a Service Request. 
This TID will be updated with the fixed kernel version once the maintenance update is released. 

Cause

A patch was merged into the SLES12 SP5 kernels in order to comply with RFC4122.

Status

Reported to Engineering

Additional Information

This change will not be reverted in SLES15+ as this is considered the new standard.

A new SAP note will be created at a later time which addresses this problem.
