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:

• 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.
