3092771 - HANA license invalid after unregister the secondary site

• After unregister or cleanup a system replication site, the HANA license got removed or is invalid.
  
  
• Prerequisite: any of these commands were executed.
• hdbnsutil -sr_unregister
• hdbnsutil -sr_cleanup
  
  
• Such a reset can be observed in the traces:

[26845]{-1}[-1/-1] 2021-06-26 16:52:32.797050 i sr_nameserver TopologyUtil.cpp(02207) : resetLandscapeId

• In combination with the "--force" option, unfortunately cannot be guaranteed that the temporary license mentioned in SAP Note 2211663 can be put into place. For that reason, an invalid license error can be received.
